Question 6

all-in-one computer
A computer that has the monitor and computer case built together and uses components that are common to both a notebook and desktop computer.

Question 7

analog
a continuous signal with infinite variations, as compared with digital, which is a series of binary values- 1s and 0s

Question 8

atx ( advanced technology extended)
The most common form factor for desktop computer cases, motherboards, and power supplies; it was originally introduced by Intel in 1995. ATX motherboards and cases make better use of space and resources than the earlier AT form factor.

Question 9

atx12v power supply
An ATX Version 2.1 power supply that provides an extra 12-v power cord with a 4-pin connector and is used with the auxiliary 4-pin power connector on motherboards to provide additional power for processors

Question 10

Audio Ports
A port that can be used by microphone, audio in, audio out, and stereo audio out connections
also called a sound port.

Question 11

base station
a fixed transceiver and antenna used to create one cell within a cellular network

Question 12

bios ( basic input/output system)
Firmware that can control much of a computers input/output functions, such as communication with the keyboard and the monitor.
Compare with UEFI

Question 13

Bluetooth
a short-range wireless technology used to connect two devices in a small personal network.

Question 14

cellular network
a network that can be used when a wireless network must cover a wide area. The network is made up of cells, each controlled by a base station. Also called a cellular WAN or wireless wide are network ( WWAN).

Question 15

Central processing unit (cpu)
The component where almost all processing of data and instructions takes place. The CPU receives data input, processes information, and executes instructions. also called a microprocessor or processor.

Question 16

chassis
a case of any type of computer.

Question 17

db9 port
see serial port

Question 18

db15 port
see
VGA (Video Graphics Array) port.

Question 19

de15 port
same as dB15

Question 20

Desktop case
a computer case that lies flat and sometimes serves double duty as a monitor stand. a tower case is sometimes called a desktop case.

Question 21

digital
a signal consisting of a series of binary values- 1s and 0s
compare with analog.

Question 22

dimm (Dual inline memory module)
a miniature circuit board installed on a motherboard to hold memory.

Question 23

display port a port that transmits digital video and audio ( not analog transmissions) and can be used in the place of VGA and DVI ports on personal computers.

Question 24

docking port
a connector on the bottom of the laptop that connects to a port replicator or docking station.

Question 25

docking station a device that receives a laptop computer and provides additional secondary storage and easy connection to peripheral devices.

Question 26

dual-voltage selector switch a switch on the back of the computer case where you can change the input voltage to the power supply to 115 V ( in the United states) or 220 V ( in other countries).

Question 27

dvi ( digital video interface) port a port that transmits digital or analog video.

Question 28

Electrostatic discharge (ESD) Another name for static electricity, which can damage chips and destroy motherboards, even though it might not be felt or seen with the naked eye

Question 29
