Grade A QUESTION AND ANSWER
Storage, Input, Processing, Output, Storage - (CORRECT ANSWEWR)Computers
use these 5 steps to operate.
System Unit - (CORRECT ANSWEWR)The full enclosure system that holds the
motherboard, RAM, GPU, PSU, harddrives, cooling, etc.
Monitor - (CORRECT ANSWEWR)This is a peripheral of the system unit, used to
display output to the user via a readable and/or interactive interface.
Keyboard - (CORRECT ANSWEWR)This is a peripheral of the system unit, used for
input from the user. It has many keys available to input in the form of alphabets,
numerals, and symbols.
Mouse - (CORRECT ANSWEWR)This is a peripheral of the system unit, used for
input from the user in the form of a handheld device that is moved around on top of a
surface. It is used to interact with the monitor. It moves a pointer on the screen.
Speaker - (CORRECT ANSWEWR)This is a peripheral of the system unit, used for
auditory output to the user.
Printer - (CORRECT ANSWEWR)This is a peripheral of the system unit, used to
create hardcopy data. Some types of these may also have built-in scanners, and/or
fax. It is an output device.
Scanner - (CORRECT ANSWEWR)This is a peripheral of the system unit, used to
create softcopies of hardcopy data. It is an input device.
USB - (CORRECT ANSWEWR)This port comes in 3 different flavors and supports
plug and play. It is one of the most common port types today, replacing the older
ports.
Ethernet - (CORRECT ANSWEWR)This port is used primarily with wired networks,
using an 8-pin RJ-45 connector.
ESATA - (CORRECT ANSWEWR)This port is used almost exclusively with external
hard drives.
S/PDIF - (CORRECT ANSWEWR)This port is supported by fiber optic cabling,
occasionally by a coaxial-type connector that screws on. It is used for audio transfer.
DVI - (CORRECT ANSWEWR)This port is used for monitors or projectors.
HDMI - (CORRECT ANSWEWR)This port is used for both audio and video,
connecting to televisions or any type of media receiver.
1/8 inch mini RCA jack - (CORRECT ANSWEWR)Used as direct links to
microphones or speakers, they are small round jacks used for audio transfer.
, Power - (CORRECT ANSWEWR)This plug is located on the back of a PSU, used to
transfer power from a wall socket to the PC.
Firewire - (CORRECT ANSWEWR)A declining connector, this plug is mainly used in
camcorders for video/audio transfer.
mini DIN - (CORRECT ANSWEWR)A legacy connector, this connector is used for
mouse and keyboard inputs. May also be referred to as PS/2 connector, named after
the first PC that used them.
9 pin DB - (CORRECT ANSWEWR)A legacy connector with a D sub serial port, it
was used with an adapter to support mice, keyboards, printers, etc.
25 pin D sub - (CORRECT ANSWEWR)A legacy connector with a D sub parallel
port, it was used primarily with printers.
VGA - (CORRECT ANSWEWR)A legacy connector consisting of 3 rows of 5 pins
each with a D sub connector, it was used for monitors or projectors.
Power Supply - (CORRECT ANSWEWR)This box takes standard household current
and converts it to either 5v or 12v DC. It is used to power the system unit.
Video card - (CORRECT ANSWEWR)a printed circuit board controlling output to a
display screen, it is used to render graphics from a simple GUI to a complex 3d
game. The more powerful the card, the better the application that it can render.
RAM stick - (CORRECT ANSWEWR)These cards hold the computer memory. Any
active program, such as the OS, a game, or application, is stored here for quick
access by the processor.
CPU - (CORRECT ANSWEWR)This is the brains of a computer. It handles every
process that goes through from the hard drive to the motherboard, managing every
element of a computer.
Motherboard - (CORRECT ANSWEWR)Every piece of the computer is connected
either directly or indirectly together from this central point. It is where the CPU is
located, controlling every element of the computer.
Optical drive - (CORRECT ANSWEWR)These play disk media, such as CD's,
DVD's, or blu-ray disks, or some can copy data to special disks in the form of burning
data. It uses a laser to read the data on the disk.
Hard drive - (CORRECT ANSWEWR)This uses platters to store data by means of
magnetic force. It uses actuator arms to record the data to the platters. It is where
every element of a program is permanently stored until otherwise deleted by the
user, or by accidental means.
Solid State Drive - (CORRECT ANSWEWR)This uses semiconductors to store data
as electronic means. It uses no moving parts, and can be generally quicker than the
platter variants. Like it's cousin, every element of a program is stored permanently
