Multimedia Forensics

The world today is moving at great speed down the road of scientific and technological progress. And nobody will be surprised with a thin LCD monitor or TV. They can be seen in almost any office. Many have already changed their fat old TVs to the new slim LCD panel. Laptops also have an LCD screen, so it is also a concern.

The advantages of LCD technology are:

1. Flicker-free (image constant, and only those pixels change color, where the movement)

2. Reflection of light from the LCD monitor is 4 times less than that of conventional CRT display

3. No harmful electrostatic potential around the monitor

4. Small and lightweight (only 5.7 kg),

5. Low power consumption

6. Perfect accuracy and geometry of the image;

7. The minimum load on the eyes (but, despite this, it is still recommended to keep your eyes from the screen every 40 minutes and look into the distance or just close your eyes and relax);

Despite the long list of benefits, LCD monitors (or TV) have a few drawbacks among which is a smaller depth of color (compared to CRT monitors and TVs) and the fragility of the backlight. With the first problem manufacturers have coped by raising the tone of color to a few tens of millions of colors. But the second problem we have to fight, to consumers. As shown by numerous examinations, the average lifetime backlight for LCD monitors (or TV) is about 30,000 hours; with an average duration of work per day is about 10 years. But, experts say, the satisfactory brightness of the lamp is observed over 10-20 thousand hours of work (the first 3-6 years). These figures may vary slightly, depending on model and manufacturer, but the fact remains. At the expiration of the term brightness decreases significantly, there are dark areas in the corners, and shade light turns yellow.

And so the question arises: how to extend the lifespan of the monitor? I propose a simple and reliable way: in the settings of your computer should be set automatically switch off the monitor after 1 minute (that is, if you do not press the buttons on the keyboard and do not touch the mouse, the monitor turns off after 1 minute). To enable the monitor again, you have to press a key or move the mouse. And in any case do not include a screen saver that you will only speed up your visit to a service center for replacement lamps. This method allows you to extend the lifespan of the monitor 2-fold or even more (the monitor will not work when you copy a DVD-ROM with something useful, or downloading a large file from the Internet, converting videos or listening to music, that is, when there is no need for constant visual inspection).

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

We would like to give you some general tips – today the Internet technologies give you a really unique chance to choose what you need at the best terms which are available on the market. Strange, but most of the people don’t use this chance. In real practice it means that you should use all the tools of today to get the information that you need.

Every day, notebooks and netbooks are gaining the popularity, despite the somewhat high prices compared to their stationary brethren. This is due to the fact that the basic rate in the world today is on the mobility and autonomy. Initially, at first it works from the network, but then we feel the need to work offline. And here rises a question about the battery life and the extension of working hours on a single charge.

Tip 1. Battery power is used absolutely in all the devices on the laptop, so when running the battery the power should be off on the unused equipment in the device manager (the main consumers, which can be disabled: adapter wi-fi, bluetooth and infrared all plug-ins, additional monitors, also all USB-controllers can be disabled for some time, network cards, and then embedded modems, etc.) If you have not figured out what you can turn off, and what – no, then a little program Battery Double can help you, which automatically turns off unused equipment and can put the processor and hard drive in economy mode.

Tip 2. Put the backlight on the lowest brightness (on some operating systems this is done automatically). Tip 3. Do not use if possible a DVD and CD, as its little motor eats a lot of energy (if there is an urgent need to use the DVD drive, then pull all necessary files directly to hard disk, and then remove the CD or DVD from the hard drive and work with these files).

Tip 4. If you’re going to adjourn for at least half an hour, then do not leave your laptop on, and send it into sleep mode or hibernation. Do not leave it in standby mode, because the processor, RAM and keyboard still remain to work. By following these tips, you can extend the time for working offline on a single charge. The following tips will help you to maintain fitness and capacity of batteries for many years.

Tip 5. If you plan to work on a laptop computer from the network (a month or more) for a long time, it is better to charge the battery up to 50% and put it in a cool location 10-15 degrees. In this mode the battery loses only 2% of its capacity per year.

Tip 6. Battery life is measured by the number of full charge-discharge cycles, so the charge to 100%, then discharge to 50% and then charging to 100% will be considered as a half of the cycle. But according to the manufacturers, should produce a full cycle of 100% -0% -100% at least once every two months for better safety and stability of the battery.

Tip 7. Do not be lazy to read the user manual for your mobile device – sometimes there is very useful information.

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

We would like to give you a final piece of advice – today the online technologies give you a really unique chance to choose what you require at the best terms which are available on the market. Funny, but most of the people don’t use this chance. In real life it means that you should use all the tools of today to get the info that you need.

Currently, there are quite a number of different graphics file formats. Nevertheless, all of them can be divided into two groups. These are files that store vector graphics, and files stored raster graphics. Raster graphics – is a format when the image is stored in the form of small dots – pixels. Accordingly, the quality of such images is limited by two factors: it is actually the size of the image in pixels, and image resolution – that is, the number of pixels per unit length (the most common pixels per inch). Files stored in raster graphics are a jpg, gif, bmp, tiff, png, psd and others.

Vector Graphics – is a format when the image is stored as an array of numbers describing the construction of images in the form of curves and the key points of the vertices. Formats of vector graphics are swf, cdr, max, ai, partly pdf.

In practice, web graphics are mainly used in two formats, raster graphics – jpeg and gif, and a vector graphics – swf. The format png is much less frequently used.

Jpeg and gif formats differ in different image compression algorithm. Since the web file size still plays a very significant value for several reasons, therefore, light weight graphics file significantly increases the speed of loading images. For different “types” of pictures fits a particular format graphics.

Determining the required format is the basic ability of a web-designer.

The format jpeg is best for photos, portraits, large pictures rich with intricate details. Compression algorithm of this format works so that, when the “weight” lessen of a picture, and therefore the quality of the image, as if “smeared out”, becomes ill distinguish the clear transitions between colors, and stray colored pixels appear as a side effect of the algorithm. The degree of compression of a file is determined each time by the designer on the basis of its needs, but the optimum ratio of the size / quality of the image compression rate is equal to 65.

Gif format is best suited for images of small size, where transparency (alpha channel) is necessary, and for animated bitmaps. Compression algorithm of the format is based on the fact that the image is given a fixed color palette (from 2 to 256 colors), and all similar shades are discarded or replaced by the adjacent colors.

Also, the algorithm calculates the image lines from left to right, and stores the information not about each pixel but considers how many pixels of the same color are in a row, and stores the information only about the color and the number of pixels. This significantly reduces the weight of the file. It is easy to see that the vertical gradient (top-down) will weigh in this case is much smaller than the gradient of the horizontal (left to right). This should be considered when creating images, especially when you create animated banners, where the weight is composed also of the number of frames and is literally a war for each byte.

Png format is rarely used. It differs from the format of gif that png to preserve more information about the file. In particular, information about the alpha channel. In gif format each individual pixel can be either completely transparent or completely opaque. This imposes restrictions on the use of transparent transitions in transparency, because of what gif files with transparency often look “jagged” at edges. However, due to the large weight png files practically are not used. It is applied a variety of visual tricks in the format gif, in particular the addition of the “transitional” pixels at the edges of the image.

When naming files you should follow the simple rules. First, it should be avoided as meaningless and “speaking” names. The file name should immediately determine its place in the web page. That is, if it’s an image to the article, it should be placed in the folder articles and its name is the id of the article. If this is the position in the directory, then in the appropriate folder (items, groups) the picture must have the name ID of the group, subgroup or product.

At the same time, if, for example, the site is very rarely write articles, you cannot add additional folders, but then the file must be on the name is uniquely associated with this section. This can be done for example by adding words to the news or art picture id (such as news-34.jpeg). If a few pictures of different sizes refer to one id it is needed to add an extension after the picture id, indicating the size (for large images – b, for small – s) (Example 38-s.gif, art-2008-b.jpeg). For several images of the same size, you can enter the serial numbers (example: art08-b_01.gif).

When naming pictures that form the design of the website, you should use the following notation: top – for the header of the site, bottom – for basement of the site, but – for various kinds of buttons, ico – for the icons, img, or pic – for other images of registration with the addition of numbers in end.

The main programs for working with images from the designer are Adobe Photoshop and Adobe ImageReady for raster graphics; Corel draw and Macromedia Flash for vector. It is also used sometimes for vector graphics software Adobe illustrator – but it’s a matter of designer’s taste, because the programs are essentially identical and have similar functionality.

The successfully passed operation of recording digital audio on the CDA (Compact Disc Audio) announced to the world about the beginning of a new era in sound recording. In 1982 in Langenhagen, near Hanover, was discovered the mass production of CDs. The rapid development of computer technology and digital technology, which began a little later, led to the necessity of compression of digital audio. The reason for this was a mass. Saving disk space, increasing the speed of transmission of digital information, the need for a sound recording format, suitable for use in the software.

In 1987, the German Fraunhofer Institute (Fraunhofer Institut für Integrierte Schaltungen) has launched a comprehensive study of the problem of encoding digital audio. This institution owns the patent on the technology MP3. Karl-Heinz Brandenburg is the “father” of the sound format, mathematician and electronics, who studied the methods of compression since 1977. In 1989, when he was received a patent on the format, a single MP3 file did not exist. In 1993, the MP3-files have been found to comply with the international standard MPEG-1.

What principles were the basis of encoding digital audio in this format?

Original audio file is divided into frames the duration of each is 0.05 seconds. Then analyzes of each frame appeared. In this case, all the sound frequencies that lie outside the range of perception of human ear are discarded. In addition, oscillations that are too high or low value of amplitude are discarded. As is known, its upper limit of human perception is of 96 dB. The lower boundary of perception depends strongly on the frequency of the sound. High and low frequencies have a higher amplitude threshold of perception. In the first phase signal of each frame, the mathematical Fourier transform as a sum of sinusoids of various amplitudes and frequencies (in fact graphically sound at any frequency is just a sine wave). In memory of recorded amplitudes and frequencies contained in the resulting formula. The second stage of processing is based on a psychoacoustic model of human perception of sound ear. For example, discarded small incremental changes in sound frequency (the signal frequency of 5000 Hz followed by a 5100 Hz signal is recorded as one with a frequency of 5000 Hz and summed duration). Another feature of the ear leads to the effect of frequency masking. Sound with a certain frequency masks other sounds with similar frequency but smaller amplitude, which is discarded. The inertia of the ear perception of sound leads to the fact that, sometime after a loud pop sound of high frequency and low amplitude is simply not heard. These sounds are also discarded by filter. The third stage is the compression of the processed signal by known mathematical methods. Data compression to MP3 is carried out on a somewhat modified version of Huffman, applying when creating an archive file in PKZIP, LHA, ZOO, ARJ. As a result of all three transformations, the information contained in the original audio file is squeezed a few times. Compression ratio in the current coder is measured in kilobits per second (kbps), and can be specified by the user. In this case, he should remember that an infinite desire to decrease the file size with increasing degree of compression leads to that the second stage of processing the sound (it is settled without any restrictions) is becoming more aggressive.

There is no single opinion on the minimum degree of audio compression admissible when it is processed. Some say that 128 kbps (compression ratio – about 10:1) is quite enough, while others prefer a value twice as large. Today, most players and encoders set the upper limit – 320 kbps, which can satisfy any expert.

Your computer can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

With the term “bitrate” we face at the mention of audio and video formats. To understand this term, you must master the process of compressing and encoding files. German scientists have laid the general principle of file compression with minimal loss. On the example of coding the original MP3 sound file is cut into fragments, the duration of 50 milliseconds, each of which is analyzed separately. In the analysis of the fragment is decomposed into harmonics of the Fourier method, of which, in accordance with the theory of sound perception by the human ear thrown those harmonics that people perceive worse than the rest. These are quieter harmonics on the back of the higher ones. As a result, emitted sounds are masked due to the inertia of hearing. The information about the harmonics left after filtering and recorded in the MP3 file, which results in a much smaller than the original WAV.

WAV-file contains detailed information about the original sound, digitized and quantized with a frequency of 44kHz. This information is stored on ordinary audio-CD. When playing there is the inverse transformation, in which the remaining harmonic is re-converted into sound waves. Some of the information about the original signal was lost, because the sound is not identical to the original. But throwing irrelevant sounds, so the human ear cannot distinguish the signal from the original order, which was packed to MP3.

Bitrate is the amount of information per unit time. Its essence – how much information about every second of recording we can spend. Naturally, as it is smaller, the smaller the size of the files have the same length of time, thus will have to throw more “extra” harmonics. Bitrates are units of measurement – kilobits per second (Kbps) and megabits per second (Mbps). MP3 audio compression algorithm is often used with 128 kbps compression. They are of two types: fixed and variable. For example, when a video compression is used with a constant bitrate a fixed amount of data is used to encode a second film. In the case of variable bitrate the codec installs eigenvalue bitrate depending on the scenes of the movie. For example, when encoding to mpeg the gain in compression is mostly obtained by retaining only the difference between adjacent frames. During a slow scene change the difference between frames is small and thus can reduce the amount of a bit rate required for playback of these scenes. However, with the abrupt change of scenes in the film, the differences in staffing increase dramatically in size and require more bitrate to play such scenes. In contrast to the constant bit rate, at a variable one cannot predict the size of the output file, it depends on the ratio of “fast” and “slow” scenes in the film.

Regarding to radio online, the downloadable sound quality of radio stations with the network also can be analyzed by bitrate. The choice between 48kbps and 128 kbps bit rate, I hope, will introduce you to a long meditation.

Probably everybody has noticed that when connecting to the Internet via dial-up-modem the connection speed gradually decreases. The fact is that when connecting new users to the server provider’s connection speed is reduced (more so if the server provider “thinks” that your modem shows no activity). To restore the connection speed you can use the so-called ping.

What is a ping?

A ping (English acronym for Packet InterNet Groper) is a program used to check the availability of the destination network by sending him a special signal (ICMP echo request) and wait for a response. Pinging is a diagnostic scan of the remote object.

– ICMP (English abbreviation for Internet Control Message Protocol) – one of four protocols of internetworking level family TCP / IP, it restores the connection in bad situations in the transfer of custom packages.

Ping can be used for full-time operating system utilities. But first you need to know IP-address of the server.

How to know IP-address of the server?

a) Windows Vista: – connect to the internet

- click Start -> Connection

- in the window “Connect to a network” right-click your connection

- from the context menu, select “Status”

- in the window “Status” tab “Details”

- in the column “Property” locate IPv4-address of the server

- in the column “Value” find the address (eg, 100.100.100.100).

b) Windows XP: – connect to the Internet

- click the network status (“monitors” in the system tray near the clock)

- in the window “Status” tab “Data”

- in the column “Property” Find IP-address of the server

- in the column “Value” find the address (eg, 100.100.100.100).

To create a shortcut to ping the server provider (listed step by step process for Windows XP, Windows Vista for the differences are minor):

- right-click on the free surface from the icons on the desktop

- from the context menu select New -> Shortcut

- in the window “Create Shortcut”, click “Browse …”

– in the window “Browse For Folder” click Computer -> drive C: (or D:, if the operating system is installed on drive D:) -> Windows -> system32 -> ping. exe -> OK (after these manipulations in the text box “Type the location of the object” will address C: WINDOWSsystem32ping.exe) -> Next

- in the next window, enter the tag mark name (the default value ping.exe, but you can change this name on the other) -> Finish

- shortcut to the newly created ping.exe appears on the desktop;

- click the right mouse button from the shortcut menu, select “Properties”

- in the window Properties: ping.exe “tab” Shortcut click in the text box “Object” after C: WINDOWSsystem32ping.exe, make one space and enter the IP-address of the server, which was found previously (eg, 100.100.100.100), then click OK.

Now, when you notice that the speed of your Internet connection drops periodically ping the server provider by clicking on the shortcut.

Notes: 1. Answers of the ping server such as “timed out a request” or “The specified node is unavailable” usually indicates a problem of the server provider.

2. Firewall server can be configured to block requests and responses; it results in the normal functioning of all network services. In this case a ping does not make sense.

3. Ping can be any node in the network, both local and global. For example, you can ping any site to find out its IP-address, it needs to use the ping utility with the-a (prefix http:// it is not necessary to paste into the command).

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

Modern society has become dependent. It is dependent from smoking, addiction to alcohol, drugs, society, state, and finally, depending on the information and communication infrastructure. Communications are developing so rapidly that mobile phones and various communication devices have become a habitual means of communication of millions of people. But who would have thought 30 years ago that today, while thousands of miles apart, you can not only communicate but also to see the face of your friend!

Firstly web-camera was made to organize and creates a teleconferencing via the Internet. Today, with this multifunction device you can shoot videos, take photographs, and conduct surveillance on the neighbors. Some advanced models even allow watching the stars and examining lunar craters.

But all the same how to choose web-camera, without knowing all the intricacies of this mysterious gadget?

When choosing a web-camera the first thing you need is to pay attention to compatibility with computer operating system, because many models are only designed for Windows. In addition to the sensor technology, it is necessary to take into account such an important parameter, as the resolution matrix. The resolution of the camera can be in the range of 0.1 to 2 megapixels (MP).

To conduct online conferences enough there is a web-camera with a resolution of 320×240 pixels. To record a small video camera with a suitable resolution there is a camera of 640×480 pixels (0.3 megapixels). Higher resolution, 1280×960 pixels, allows large-scale photographs.

Matrices differ in manufacturing technology. Nowadays two of them are popular – CMOS and CCD. Matrix CCD is preferred, since it gives a better image, creates less noise.

When choosing a web-camera it is also necessary to carefully look at the type of connection to the computer. Modern web-camera is connected with an USB interface. Version USB 1.1 is obsolete today, and replaced by a high-speed – USB 2.0.

Connecting of the web-camera to the Internet can be managed through a 3G modem, which is now myriad. Data transfer rate is typically 3.2-7.2 Mbps. Cable modems provide Internet access over telephone networks or cable television networks. Maximum possible rate of data reception up to 40 Mbps, and data transfer rate of 10 Mbps. More expensive models of web-cameras are equipped with wireless interfaces. In this case, Wi-Fi most technology is often used for signal transmission.

For the most advanced users can be selected a camera with extra features, you can use it to take pictures, shoot video, control contrast, brightness, frame rate. As well as built-in microphone.

The look of the camera is important as well as the type of its attachment to the computer.

So, summarizing, we can say that using these features when purchasing a web-camera, you will avoid errors and get exactly what you want.

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

NAS is a set of hard disks connected to the LAN. It features from a simple external drive connected to the router via USB with the greatest functionality, scalability, provision of additional services and greater fault tolerance (if using RAID). In fact, it is inexpensive miniserver for home or for your company.

Firstly it is for storing data. If there is more than one computer at home, then increase the volume of hard disk drives in each cost more. Yes, the backup of your data should be stored somewhere in case your computer crashes or virus infection. DVD collection, too, can build out and no longer fear that the disc will be scratched and couldn’t be read. Upload your favorite music and listen to it from any location via the network. Put your favorite photos of cats and show to your friends. Many modern TVs have a built-in media player and can connect to the network, so you needn’t a DVD-player. No needs to wait to download the file from the Internet – give the task to the server and calmly went to sleep. Or use it as a print server. You can show a home video or photos to relatives in another city: recorded, opened access, threw a link to family.

Which is to choose?

There are two options: to buy or to assemble it yourself. It all depends on your ability and desires.

In the first case everything’s limited by the financial resources. The only advantage of the purchased option is the simplicity: bought and turned on, tuned to work. Everything else is minuses. Not very high speed, inability to updates and improvements in terms of hardware, limited opportunities to expand software functionality.

In the second case, there is a total space for creativity. Any parts, any software, a variety of services. There are already tried and tested options for enthusiasts, and it is worth to study them before making a decision. Find them easy to dial in any search engine “NAS by hands” and read.

The main points to consider when designing:

NAS will operate around the clock so it is desirable to reduce power consumption and heat dissipation. Not worth tinkering based server motherboards from PC or server, and powerful processors. Quite fit mini-ITX motherboard with a processor Atom.

The server should be as inconspicuous. If it is going to shine lights and make noise all day and night, it will trouble the surrounding people and you will have to redo it. Therefore, think from the beginning about the cooling and noise reduction, especially if the noise is above 30dB (loud whisper). For hard drives, there are special cases, which, except for noise reduction, also reduce vibration and temperature. Fans can be replaced by silent or lowered to a reasonable minimum speed of existing ones.

The server should not require daily intervention, work quietly, without a monitor, keyboard and mouse, and managed through a web-interface or remote desktop.

If you collect it yourself, what do you need?

A motherboard. As already stated above, it is quite suitable mini-ITX with integrated processor, Atom. It is worth noting the number of SATA connectors on the motherboard that was enough for all your disks. Built-in video and audio can be any; they still will not be used.

Memory. One or two gigabytes should be sufficient. It is only necessary to select a supported motherboard.

Case. Any, as long as everything is included and the case is well cooled and produces no noise. If the power supply is built in, it should be quiet, and the power connector should be suited to the chosen motherboard.

Discs. Here only your preferences and needs play a role. There is no sense to chase for the Green-series (low power consumption and heat dissipation, reduced speed) if you have a spinning engine and other services are constantly accessing the disk.

The operating system. MS Windows there is unlikely to fit (although some have), it is better to use Linux. Reliable, easier, faster, and no viruses.

Your computer can get into serious problems if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

Some viruses infect Microsoft Windows, they disable the printing subsystem. The symptoms of infection are: when you try to print a file, a message that the print subsystem is unavailable appears on the screen. When you try to display the properties of the connected printers the error message appears on the screen: “Unable to display the printer properties. Print subsystem is unavailable “. An unpleasant consequence is that even after the treatment the print subsystem remains unavailable.

The algorithm for the fault:

- open the Windows Task Manager (in any way – by using Ctrl + Alt + Del, or by using Start -> Run … -> taskmgr -> OK) and unload (if any) spoolsvv.exe spooldr.exe files from the memory (these are executable files of the virus that isolates the printing subsystem)

- check your anti-virus system monitor (if the system does not treat everything else is meaningless!)

- find and delete files WINDOWSsystem32spoolsvv.exe WINDOWSspooldr.exe (since These files usually have the attributes Hidden, System, Read-only, so click the Folder Options dialog box on the View tab, select “Show the contents of system folders”, uncheck “Hide protected operating system files”, select “Show hidden files and folders” )

- Click Start -> Run -> msconfig -> OK;

- Settings dialog box, click System Startup tab

- uncheck all startup items from spoolsvv.exe and spooldr.exe files -> OK (viruses, disabling the printing subsystem prescribes autorun files WINDOWSsystem32spoolsvv.exe and WINDOWSspooldr.exe instead of WINDOWSsystem32spoolsv.exe);

- click Start -> Settings -> Control Panel -> Administrative Tools -> Services

- Find the spooler

- double click the left mouse button activating the Spooler print

- click Start (or Stop -> Start)

- check the type of start -> Auto

- check the text box executable file -> C: WINDOWSsystem32spoolsv.exe;

- click OK;

- run the Registry Editor Windows: Start -> Run … -> regedit -> OK;

- find the section [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSpooler];

- check the REG_EXPAND_SZ-parameter ImagePath: it should be %SystemRoot% system32spoolsv.exe (viruses install for example spoolsvv.exe or spooldr.exe instead of spoolsv.exe);

- Find the section [HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesSpooler] and [HKEY_LOCAL_MACHINESYSTEMControlSet002ServicesSpooler];

- value ImagePath REG_EXPAND_SZ-parameter should be %SystemRoot% system32spoolsv.exe.

- Click Start -> Settings -> Printers and Faxes -> View – File menu -> Server Properties -> Advanced tab

- check the text box, the print queue -> C: WINDOWSSystem32spoolPRINTERS.

Notes:

1. If you cannot run Task Manager, see What to do if the message “Task Manager disabled by administrator” appears.

2. If the menu item Folder Options isn’t available, see What to do if menu item “Folder Options” isn’t available?

3. If you cannot run the Registry Editor Windows, see What to do if the message “Editing the registry is prohibited?

4. Be careful when handling the Register! Incorrect use of Registry Editor can cause serious problems, until you reinstall the operating system!

5. Remember that warning is easier than cure! Use a firewall and reliable anti-virus software with regular (at least once a week!) updated databases.

Your PC can get into serious troubles if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

We would like to give you some general tips – today the Internet technologies give you a truly unique chance to choose exactly what you need at the best terms which are available on the market. Funny, but most of the people don’t use this opportunity. In real practice it means that you must use all the tools of today to get the info that you need.

Print spooler is a program planner which accepts documents sent by the user to print, stores them (on the disk or in memory) and sends in the order of the selected printer. Disk address of the Print Spooler (Spooler SubSystem App) – WindowsSystem32spoolsv.exe;

Buffering print is a creation of a print queue allowing the processor of the computer to expedite the processing of a print job due to its temporary storage on the hard disk before being sent to the printer. As a result, the processor can more quickly return control to the program from which you print than if the processing of all jobs and sending it directly to the printer is performed by the program.

To cancel a print job – XP: Click Start -> Settings -> Printers and Faxes (Vista: Start -> Control Panel -> Printers), – in the dialog Printers and Faxes (Printers), double clicking on the left mouse button, open the printer you want (or click your printer, right-click from the context menu, select Open) – in the print queue, right-click the item whose seal is required to stop, and then click Cancel (to cancel all jobs in the Printer menu, click Clear the print queue) .

Notes: 1. If you cannot cancel a print job using these steps, click the Cancel button on the printer.

2. To quickly view a list of current print jobs, double-click the printer icon in the taskbar notification area (near the clock).

3. The user can cancel only its own print jobs. To cancel a print job of another user he must have a permission to manage documents on the printer.

Problems with cancellation of print jobs to Windows Vista and XP “do not like to” cancel the print job “on the fly” (when the seal is already in progress). In such cases, to manage to clean the print queue is often possible not at once, but as long as you do not clean the print queue, the next print job will fail. Sometimes cancel a print job can only after restarting (and sometimes after restarting the print job, which we already seem to be canceled, the printer starts to print). In such cases, you can try to manually clear the spool folder (Windowssystem32spoolPRINTERS). True, this is not always possible because this folder has attributes Hidden, System, Read-only, so Windows will not let you specifically “disorderly” in this folder. You can try to clean the print queue using an alternative file manager, for example, Total Commander (in the settings should be set to box item Show hidden files and system files).

There is another – a radical! – Method:

- Complete all the print job

- stop the print spooler

- create a special folder for the job print queue (for example, C: spool);

- specify in the settings of the print server (or via the Registry), its location

- start spooler

- Now for the problems with the abolition of print run of the Service (or Task Manager)

- unload the print spooler spoolsv.exe;

- open the folder C: spool and delete all temporary files (each print job, as a rule, “issued” a pair of spool files – * . SPL, *. SHD, for example, 00005.SHD and 00005.SPL (or FP00001.SPL and FP00001.SHD). Some printers in your print queue, in addition to the files *. SPL, *. SHD, are also Files *. tmp);

- run the print spooler.

How to unload (stop) print spooler (spooler)

- Click Start -> Settings -> Control Panel -> Administrative Tools -> Services (or Start -> Run … -> drop-down menu Open the Run dialog box, type services.msc – > OK);

- in the Services dialog box, locate the Print Spooler

- click Stop Service. How to run a print spooler

- click Start -> Settings -> Control Panel -> Administrative Tools -> Services (or Start -> Run … -> drop-down list View Run dialog box, type services.msc -> OK);

- in the dialog Services window, find the Print Spooler

- click Start the service.
