Aperipheralis an adjunct, an accessory, not something required.

ex: printers, speakers, video card, monitor

Question 6

What is a computer component?

Answer 6

A component is essential to the computer

ex: cpu, motherboard, ram

Question 7

What is a video port?

Answer 7

a port that can be used to connect a monitor or other display, such as a TV, to a computer

Question 8

What is the difference between broadband and narrowband EMI?

Answer 8

• narrowband affects less than broadband
• narrowband is a short disruption that does not cause permanent harm in the system

-broadband can cause permanent damage to devices

Question 9

What is a search engine?

Answer 9

A program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web is called a search engine.

Question 10

What is a browser?

Answer 10

A web browser is a software application that allows you to access information using the World Wide Web.

Question 11

What is a motherboard?

Answer 11

Contains all necessary components of computer, like cpu, ram, video cards etc.

Question 12

What is a processors register size?

Answer 12

The number of bits processed at one time

Today, cpus have register sizes of 64 too 128 bits

Question 13

What are buses? Say the difference between internal and external?

Answer 13

An internal bus are the electronic lines inside the CPU

The external bus connects the
CPU to external devices

Question 14

What is an ALU?

Answer 14

An arithmetic logic unit. part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words

Question 15

What are pipelines?

Answer 15

Processors have multiple pipelines, or separate internal buses that operate simultaneously
Process are broken down into smaller tasks and each line helps complete the entire process faster
A 32- or 64-bit CPU can have separate paths, each of which handles 32 or 64 bits
Debate continues about whether a longer pipeline improves performance

Question 16

What is a multi-core processor?

Answer 16

A CPU that combines two cores in a single unit

Question 17

How to cool the processor?

Answer 17

Using a cooling fan , heat sink, or liquid cooling

Question 18

How to install processor?

Answer 18

Gently, by applying zero force and just letting it drop in the right position with the triangle

Question 19

What is a GPU?

Answer 19

A GPU provides better video card performance with an adapter

Question 20

What is PCI? What is PCIE?

Answer 20

Peripheral Component Interconnect, an industry-standard, high-speed bus found in nearly all desktop computers used to install graphics/video cards and sound cards.

PCIE is basically a better and newer version of PCI. The E stands for Express

Question 21

What is AGP?

Answer 21

Accelerated Graphics Port, Bus interface for graphics adapters developed from the PCI bus. It is better to put graphics here then PCI.

Question 22

What is the power supply?

Answer 22

The power supply converts AC to DC, distributes DC power to components throughout the computer, and provides cooling through the use of a fan located inside the power supply.

Power from wall socket? High Voltage AC

Power needed by computer? Low Voltage DC

Question 23

What are power protection? Give 4 examples

Answer 23

Surge suppressor: helps so that overvoltage isnt an issue

Line suppresor: converts at the wall socket before the computer

UPS: provides power during an outage and 
conditions the voltage when there is no outage FOR a short amount of time

SPS: provides power during an outage for a long time

Question 24

What is hyper-threading?

Answer 24

allows a single CPU to run multiple tasks simultaneously rather than sequentially, which improves performance in most situations.

Question 25

What is the chipset?

Answer 25

manages the flow of data between components on a motherboard. It’s the traffic controller between the CPU, GPU, RAM, storage, and peripherals.

Question 26

What is clock speed?

Answer 26

Clock speed is the number of times a second that a circuit operates and is most associated with the central processing unit (CPU). It is measured in hertz, or cycles per second.

Question 27

What is Cache memory?

Answer 27

Cache memory is a chip-based computer component that makes retrieving data from the computer’s memory more efficient. It acts as a temporary storage area that the computer’s processor can retrieve data from easily.

Question 28

What is overclocking?

Answer 28

term for increasing a component’s CPU (Central Processing Unit or computer hardware) to speed up its performance.

Question 29

What is processor pipelines?

Answer 29

a technique for breaking down a sequential process into various sub-operations and executing each sub-operation in its own dedicated segment

Question 30

What is Processor threads?

Answer 30

a sequence of instructions given to the CPU by a program or application

Question 31

What is BIOS?

Answer 31

Basic input/output system:
