GRAPHICS MEMORY of computer

Graphics Memory is the memory that stores your Imagery (Desktop Picture, Game Scenes, Photographs, Icons, Text and so on). It is a microchip on the Graphics Card. The main job of a graphics card is to store Imagery inside its graphics memory and then display that imagery, on the monitor screen, when a program asks it to. For example. If you are editing a photograph the paint package would of allocated some of the graphics memory as file memory (for the original photograph) and some of the graphics memory as edit memory (for editing purposes) - In the same way the file memory and edit memory was allocated in the Microsoft Word 2007 explanation above. The graphics card will not only display the photograph (file memory) on the monitor screen, but it will also update (refresh) the monitor screen instantly every time you edit the photograph. In the same way that Microsoft Word 2007 updates instantly any changes you make to a document. Graphics memory is also in charge of storing other imagery. For example. If you have one game open, a paint program open and the Internet open it is graphics memory storing the imagery of those three programs. The more programs open that use graphics memory the more tasks (jobs) you are giving the graphics card. Meaning. If you give it too much to do and/or it runs out of graphics memory it will not be able to update the monitor screen quick enough, which means editing and game playing for example will not be instant. The monitor screen will update (draw the imagery) so slowly that it would not be worth editing a photograph or playing a game. A normal sign of this is when the monitor screen is updated (drawn) line by line as opposed to instantly. So get a good Graphics Card with plenty of Graphics Memory because the one built into the computer might not be good enough for your needs.

ROM / RAM of computer

Memory is known by two types. ROM (Read Only Memory) which means hardware and software can only read the byte values stored inside rom memory and RAM (Read Access Memory) which means hardware and software can not only read the byte values stored inside ram memory but they can also, temporarily, change the byte values stored inside ram memory.

ROM memory is a microchip on a motherboard (green microchip board), such as a Modem motherboard, that contains the instructions (byte values) needed to make the hardware (Modem) work. This is why ROM memory cannot have its byte values changed. The instructions (byte values) are preprogrammed onto the microchip, so that when you first switch on the computer the instructions (byte values) are always the same.

RAM memory is a microchip that is permanently fitted onto a Card (small motherboard), such as a Graphics Card or Memory Card, or a single removable microchip that you attach to the main motherboard. The main motherboard is the big green microchip board inside the computer (base unit). RAM memory can have its byte values temporarily changed, and read, so that you can change Graphics settings (Graphics Card) or store data (Memory Card) for example. Even though RAM memory is cleared when you switch off or restart the computer, because it is meant as a temporary storage place only, the data inside the memory is normally saved by a program (as a file) beforehand. For example. If you change the Modem (hardware) settings using a modem program it will save your changes as a settings file on the hard drive before the computer is switched off or restarted. When the computer is switched on again the modem uses its default (normal, preprogrammed) settings before looking at, and using, the settings from the saved settings file. The modem uses its default settings first for two reasons. One is so that it knows it is setup correctly (by using its normal, manufacturer's, preprogrammed settings) and two is in case the settings file is corrupt, damaged or missing. If it reads a settings file incorrectly (i.e because it is corrupt) you may get problems with the modem or it may revert back to its default settings.

What is a computer virus?

A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation. A computer virus may corrupt or delete data on a computer, use an e-mail program to spread the virus to other computers, or even delete everything on the hard disk.

Computer viruses are most easily spread by attachments in e-mail messages or by instant messaging messages. Therefore, you must never open an e-mail attachment unless you know who sent the message or unless you are expecting the e-mail attachment. Computer viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread by using downloads on the Internet. Computer viruses can be hidden in pirated software or in other files or programs that you may download.
