DefinitionsDiy-Computer-Repair can help!Need to know what that tech said? Geek got you confused? Here is a small glossary of definitions I have put together to lower the confusion level.
A
AGP - Accelerated Graphics Port: Allows for
acceleration of 3D computer graphics, this means that the graphics are read from
the system ram (memory) by the adapter instead of being processed through the
system processor. Thus speeding up the display of 3D graphics.
Fix It! Your CPU - Central Processing Unit or processor - see processor Return to topD Deframentation - The process of taking all the parts of a file and writing them to contagious blocks or sectors of a hard drive.  DIMM - Dual Inline Memory Module, 168 or 184 pin memory module DDR - Double Data Rate, 240 pin memory Module Disk - There are three types of disks, Floppy, Hard, and CD ROM. DVD - Digital Versatile Disc, same format and size as the CD-ROM with a higher capacity. Writeable DVD's created on a computer have the capacity to be used in regular DVD players. Data storage on DVD's can be either 4.7 Gig or 8.4 Gig with the Dual Layer DVD. Decimal - Base 10 numeric system, how humans count. Return to top E EPROM or EEPROM - Electronically Programmable Read Only Memory. Some devices have a Read Only Memory chip for programming the functions of the device. This memory is non-volatile, it can not be erased. EPROM's are chips that can be erased and reprogrammed. EEPROM's can be erased electronically, you system bios is a EEPROM for example. ESD - Electro Magnetic Discharge, static electricity that builds up naturally by movement. Has catastrophic effects on electronic components when discharged. Grounding will dissipate the static electric with out damage to components. Encryption - A process that will scramble a word, document, or program. Making it unreadable by normal processes, such as a word processor or text editor. Encrypting takes a special program that uses two 'keys' created by the person requiring the encryption. The 'keys' are called a 'public key' and a 'private key' the strength of the encrypted file or word depends on how 'strong' the algorithm is that creates the 'key pair'. Once the object. file, word, or program) is encrypted it can only be decrypted by with the key pair in unison.

Fragmentation - Fragmentation is defined as
the fragmenting of a file when it is written to a device. This happens on hard
drives when the capacity of the drive does not accommodate the complete file in
contiguous (one after another) blocks. IDE Integrated Drive Electronics. The integration of electronics inside
the body of the drive allows for more control over the capacity of the drive.
Before IDE all controls were on the outside of the drive, thus limiting the
capacity of the format of the platter. When the electronics were moved to
circuit boards inside the drive the capacity has increased by a million fold,
soon more than a billion fold.

for music in the
1980's, early in the 1990's CD ROM Drives became available for the computer
market. Writeable CD's with the correct format can be used in Audio CD players,
or you can store up to 800 meg of data on one disk. Also comes in Re-Writeable
format.
from the disks in the early 1970's, these disks were 8 inch in a thin
plastic sleeve, when you picked up one it had a tendency to bend, or flop
around. Newer disks come in a more ridged plastic case but are still bendable to
a certain degree before they break.
