BIT
|
A bit is a single digit number in base-2 (a zero or a one) and is the smallest unit of computer data.
|
|
|
BYTE
|
A byte is a set of 8 bits that represent a single character in the computer's memory.

|
|
|
BINARY
|
- is a two-digit (Base-2) numerical system, which computers use to store data
|
|
|
HEX

|
|
|
ROM
|
"Read-Only Memory."
|
|
|
PROCESSOR
|
This chip is the heart of a computer, also referred to as the "microprocessor," the processor does all the computations.
|
|
|
HARDWARE
|
Computer hardware refers to the physical parts of a computer and related devices.
|
|
|
MB
|
A megabyte is 2 to the 20th power, or 1,048,576 bytes. It can be estimated as 10 to the 6th power, or one million (1,000,000) bytes.
|
|
|
GB
|
A gigabyte is 2 to the 30th power, or 1,073,741,824 bytes. It can be estimated as 10 to the 9th power, or one billion (1,000,000,000) bytes.
|
|
|
TB
|

|
AUDIO PORTS
|
AUDIO JACKS, OR Audio connectors are electrical connectors for carrying audio signalsof either analog or digital format. Analog A/V connectors often use Shielded cable to inhibit radio frequency interference (RFI) and noise
|
|
|
BLUETOOTH
|
- wireless technology enables communication between Bluetooth-compatible devices. It is used for short-range connections between desktop and laptop computers, PDAs (like the Palm Pilot or Handspring Visor), digital cameras, scanners, cellular phones, and printers.

|
DIMM
|
Dual In-Line Memory Module." It is a type of computer memory. A DIMM is a small circuit board that holds memory chips.
|
|
|
DRAM
|
- "Dynamic Random Access Memory." DRAM is a type of RAM that stores each bit of data on a separate capacitor. This is an efficient way to store data in memory, because it requires less physical space.
|
|
|
EEPROM
|
Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration tables or device configuration.
|
|
|
EPROM
|
(Erasable Programmable ROM) A rewritable memory chip that holds its content without power..
