●● 8 -pin 12-V connector
Answer: An auxiliary motherboard connector, which is used for extra
12-V power to the processor, providing more power than the older 4-pin
auxiliary connector
●● 20-pin p1 connector
Answer: The main motherboard power connector used in the early atX
systems
●● 24-pin p1 connector
Answer: The main motherboard power connector used today also called
the 20+4 pin connector
●● accelerometer
Answer: A type of gyroscope used in mobile devices to sense the
physical position of the device.
●● airplane mode
,Answer: A setting within a mobile device that disables the cellular, Wi-
Fi, and Bluetooth antennas so the device cannot transmit signals
●● all-in-one computer
Answer: A computer that has the monitor and computer case built
together and uses components that are common to both a laptop and a
desktop computer
●● analog
Answer: A continuous signal with infinite variations. Compare with
digital, which is a series of binary values—1s and 0s
●● ATX (Advanced Technology Extended)
Answer: The most common form factor for computer systems presently
in use, originally introduced by Intel in 1995. ATX motherboards and
cases make better use of space and resources than did the earlier AT
form factor.
●● ATX12V power supply
Answer: An ATX Version 2.1 power supply that provides an extra 12-V
power cord with a 4-pin connector to be used by the auxiliary 4-pin
power connector on motherboards used to provide extra power for
processors.
●● audio port
, Answer: A port that can be used by a microphone, audio in, audio out,
and stereo audio out. Also called a sound port
●● base station
Answer: A fixed transceiver and antenna used to create one cell within a
cellular network.
●● BIOS setup
Answer: The program in system BIOS that can change the values in
CMOS RAM also called CMOS setup.
●● BIOS (basic input/output system)
Answer: Firmware that can control much of a computer's input/output
functions, such as communication with the keyboard and the monitor.
Compare with UEFI.
●● Bluetooth
Answer: A short-range wireless technology used to connect two devices
in a small personal network.
●● cellular network
Answer: 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
