Answers 100% Pass
LGA - ANS Land Grid Array. A chip interface standard that places the pins on the circuit board
instead of on the chip packaging. The pins do not insert into sockets. The chip has an array of
lands or flat conductive pads that interface with the pins by surface contact only.
Where are the 5 steps do Computers use to operate? - ANS 1. Storage
2. Input
3. Processing
4. Output
5. Storage
What is a system unit? - ANS The full enclosure system that holds the motherboard, RAM,
GPU, PSU, harddrives, cooling, etc.
What is a monitor? - ANS This is a peripheral of the system unit, used to display output to
the user via a readable and/or interactive interface.
What is a keyboard? - ANS 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.
What is a mouse? - ANS 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.

What is the speaker? - ANS This is a peripheral of the system unit, used for auditory output
to the user.
What is a scanner? - ANS This is a peripheral of the system unit, used to create softcopies of
hardcopy data. It is an input device.
Describe the functions of a Printer - ANS 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.
USB - ANS 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 - ANS This port is used primarily with wired networks, using an 8-pin RJ-45
connector.
ESATA - ANS This port is used almost exclusively with external hard drives.
S/PDIF - ANS This port is supported by fiber optic cabling, occasionally by a coaxial-type
connector that screws on. It is used for audio transfer.
What is a DVI? - ANS This is the legacy port used for monitors or projectors. Supports both
digital and analog outputs.
What is a HDMI - ANS This port is used for both audio and video, connecting to televisions or
any type of media receiver.
1/8 inch mini RCA jack - ANS Used as direct links to microphones or speakers, they are small
round jacks used for audio transfer.

Power - ANS This plug is located on the back of a PSU, used to transfer power from a wall
socket to the PC.
Firewire - ANS A declining connector, this plug is mainly used in camcorders for video/audio
transfer.
mini DIN - ANS 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 - ANS 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 - ANS A legacy connector with a D sub parallel port, it was used primarily with
printers.
VGA - ANS 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 - ANS This box takes standard household current and converts it to either 5v or
12v DC. It is used to power the system unit.
What is a video card? - ANS 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.
What would be sufficient power supply for a workstation set up with two CPU processors
needing 100 W GPU that needs 200 W and five brand drives that need 9 W each. - ANS 500
Watts

what is a RAM stick? - ANS 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.
describe a CPU - ANS 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.
what is a Motherboard - ANS 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.
what is a Optical drive - ANS 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.
What is a hard drive? - ANS 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.
A solid state drive can be used as a substitute for a hard disk drive. - ANS 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 here, until otherwise deleted by the user, by accidental means, or simply by
conductor burnout.
CPU (what does it stand for) - ANS Central Processing Unit
What's the significant about AMD, Intel - ANS Two of the largest CPU manufacturers
what is CPU-Z - ANS This program is available free on the internet. It allows the user to see
the specifications of their computer, from the CPU to the GPU.
