A

AT or Advanced Technology: A design of Motherboard released in 1985.

ATX or Advanced Technology eXtended: in 1995 the ATX design of motherboard replaced the AT design and is the most common computer motherboard (07/12/2016).

AGP or Accelerated Graphics Port): High-speed port to attach a video card to a computer.

B

Bit: is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0 or 1.

BitLocker: A hard drive encryption tool in Windows Vista Enterprise and Ultimate. BitLocker addresses threats of data theft or disclosure from lost, stolen or inappropriately decommissioned PC hardware.

Byte: is a unit of digital information that most commonly consists of eight bits. the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.

C

Cache: location were prevoiusly accessed data is stored. Data stored in the cache can be accessed and served faster. Cache can be either Hardware/Software base.

CPU or Central Processing Unit: is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

D

Disk: A round plate on which data can be encoded. There are two basic types of disks: magnetic disks and optical disks.

E

Electromagnetic induction: the production of an electromotive force across an electrical conductor.

Expansion Port: Usually a slot that allows specific devices to connect to your computer. (USB, Firewire, Printer/Parallel).

F

Form Factor: The physical size and shape of a device. It is often used to describe the size of circuit boards.

G

H

Hot swapping or hot plugging: the functions of replacing computer system components without shutting down the system.

I

IDE or Integrated Drive Electronics: is an interface for mass storage devices, in which the controller is integrated into the disk or CD-ROM drive.

I/O (Input/Output): All things related to computing and networking is either Input or Output. Some things can be both.

J

K

KISS or Keep It Simple Stupid: The concept of keeping computing simple, so it can be explained in simple layman terms.

Memory:

Memory for Laptop: 200-pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. 200-pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2-6400 SDRAM, DDR2 PC2-5300 SDRAM, DDR2 PC2-4200 SDRAM and DDR2 PC2-3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200-pin SODIMM slots and a DDR- or DDR2-enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

The number of black components on a 200-pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144-pin SODIMMs, 200-pin SODIMMs have one small notch within the row of pins; however, the notch on the 200-pin SODIMMs is closer to the left side of the module.

Moore's Law: Moore's law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel, whose 1965 paper described a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade.

H

Hot swapping or hot plugging: the functions of replacing computer system components without shutting down the system.

I

IDE or Integrated Drive Electronics: is an interface for mass storage devices, in which the controller is integrated into the disk or CD-ROM drive.

I/O (Input/Output): All things related to computing and networking is either Input or Output. Some things can be both.
