1. Installing Hardware & Display Components

Question 1

What is the difference between memory and storage?

Answer 1

Memory is volatile, meaning that it requires power to retain its data.
Hard drives or storage is static.

Question 2

SSD

Advantages

Disadvantages

Answer 2

Solid State Drive

Advantages:

• No Moving parts
• Faster access time
• Greater reliability
• require less power
• produce less noise

Disadvantages:

• More expensive
• Traditional hard drives tend to have more storage capacity

Question 3

HDD/SDD Replacement

Answer 3

• Backup all data
• Create or obtain a recovery disc

Question 4

PAN

Answer 4

Personal Area Network

Question 5

Biometric security devices

Answer 5

• Fingerprint readers - found on laptop tablet and smart phones
• Facial Recognition
• Iris scanners
• voice recognition - easiest to circumvent

Question 6

NFC

Answer 6

Near Field Communication

Question 7

LCD

Answer 7

Liquid Crystal Display

Two primary methods of providing light

CCFL - cold cathode fluorescent light
LED - light-emitting diodes

There are several different iterations

IPS - in-plane switching - considered to have the best color accuracy and viewing angles and overall image quality.
PLS - place to line switching
VA - vertical alignment
TN - twisted nematic
TTL - transistor translator logic

Advantages

lightweight technology
lower power consumption

Disadvantages

relies on background lighting
since this light is always on, there is no true representation of black

Question 8

IPS

Answer 8

In Plane Switching - Provides better colour but it has much slower reponse time and more expensive.

Question 9

TN

Answer 9

Twisted Nematic - Twisted nematic (TN) is the older of the two major technologies for flat-panel displays. While it provides the shortest response time, has high brightness, and draws less power than competing technologies, it suffers from poor quality when viewed from wide angles. It suffers color distortions when viewed from above or from the sides.

Question 10

VD

Answer 10

Vertical Alignment - Monitors with VA LCD panels provide the advantages of wide viewing angles and high-contrast ratios and reproduce colours well.

Question 11

OLED

Answer 11

Organic Light-emitting diode - It uses an emissive electroluminescent layer of organic compounds that emit light in response to an electric current. An interesting characteristic of these displays is their flexibility and transparency. This means they can roll up for storage (like a mat), and you can see through the display to objects behind the display. These displays are now available but quite expensive.

Question 12

Laptops

Physical Chip in a laptop is called.

Answer 12

SODIUMM - small outline dual inline memory module

Question 13

What is the role of the CPU?

Answer 13

Central Processing Unit - is to control and direct all the activities of the computer using both internal and external buses.

Question 14

What is DIMM?

Answer 14

Dual in-line memory module

Question 15

What is SODIMM?

Answer 15

small outline dual in-line memory module

Question 16

Bus Architecture

Answer 16

collection of signal pathways

Question 17

Chipsets

Answer 17

Is a collection of chips or circuits that perform interface and peripheral functions for the processor. Provides interfaces for memory, expansion cards, and on board peripherals.

Question 18

PCI Expansion Shots

Answer 18

Peripheral Component Interconnect

Question 19

What is another type memory?

Answer 19

Cache Memory which is a small and fast and logically sits between the CPU and RAM

Question 20

What is the BIOS chip?

p- 34

Answer 20

Basic Input/Output System which is burned into a chip.
This special memory chip contains the BIOS software system that boots the system and allows the operating system to interact with certian hardware in the computer.

Question 21

CMOS Memory Chip

p- 40

Answer 21

Complementry metal oxide semiconductor memory chip
