LGA - ANSWER 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? - ANSWER 1. Storage
2. Input
3. Processing
4. Output
5. Storage
What is a system unit? - ANSWER The full enclosure system that holds the motherboard,
RAM, GPU, PSU, harddrives, cooling, etc.
What is a monitor? - ANSWER 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? ANSWER 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? - ANSWER 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? - ANSWER This is a peripheral of the system unit, used for auditory
output to the user.
,What is a scanner? - ANSWER 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 - ANSWER 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 - ANSWER 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 - ANSWER This is typically wired, using an 8-pin RJ-45 connector.
ESATA - ANSWER This connector is used almost exclusively with external hard drives.
S/PDIF - ANSWER 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? - ANSWER This is the legacy port used for monitors or projectors.
Supports both digital and analog outputs.
What is a HDMI - ANSWER This port is used for both audio and video, connecting to
televisions or any type of media receiver.
1/8 inch mini RCA jack - ANSWER Used as direct links to microphones or speakers, they
are small round jacks used for audio transfer.
Power - This plug is found on the rear of a PSU; it is used to provide power from the wall
socket to the PC.
Firewire - This is a diminishing connector; however it is primarily used on the rear of
,camcorders to transfer video/audio.
mini DIN - ANSWER A legacy connector, this connector is used for mouse and keyboard
inputs. Sometimes known as PS/2 connector and named after the first PC that used
them.
9 pin DB - ANSWER A legacy connector featuring a D sub serial port was used with an
adapter to support mice, keyboards, printers etc.
25 pin D sub - ANSWER A legacy connector with a D sub parallel port, it was used
primarily with printers.
VGA - ANSWER 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 - ANSWER This box takes household current and converts it either to 5v
or 12v DC. It is used to power the system unit.
What is a Video card? - ANSWER 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 needing 200 W and five brand drives needing 9 W each.
- ANSWER 500 Watts
what is a RAM stick? - ANSWER 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 - ANSWER 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 - ANSWER 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 - ANSWER 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? - ANSWER 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. - ANSWER 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 - ANSWER Central Processing Unit
What's the significant about AMD, Intel - ANSWER Two of the biggest CPU
manufacturers
what is CPU-Z - ANSWER This application is free on the internet. It lets the user view
their computer's specs from CPU to GPU.
Hertz - ANSWER This term is used for Cycle per second.
Giga - This is the word that means Billion, can also be used with other combinations of
terms, below.
