1

A special very high speed memory called __________ is used to increase the speed of processing by making current programs and data available to the CPU at a rapid rate.

Cache

2

Most of the main memory is made up of what two chips

RAM integrated Chips
ROM chips

3

What does RAM stand for

Random Access Memory

4

RAM is available in two possible operating modes What are they?

Static and Dynamic

5

ROM stands for what

Read only memory

6

ROM is used for..........?

storing programs that are permently resident in the computer and for tables of constants that do not change in value once the production of the computer is completed

7

What is Bootstrap Loader

It is a portion of ROM needed for storing an initial program, which is to start the computer software operating when the power is turned off

8

A Cluster is the....

smallest unit of disk space that MS-DOS could allocate to a file.

9

What does a cluster consist of

One or more Sectors

10

How is cluster sized determined

By the OS when the disk is formatted

11

(cluster) Generally, the larger the disk drive;.....

the more sectors per cluster

12

Each sector holds

512 bytes (FAT 32)

13

Cluster are too small......

to hold larger files

14

FAT sectors are gathered in clusters:...?

2,4,8,16,32,64 sectors

15

NFTS stands for what?

New Technology file System

16

What system does Windows 7, and 8 hold and with how many bytes per sector

NFTS
4096 bytes per sector

17

Partitioning makes hard disk compatible with the.......

Operating system

18

Partitioning prepares what....

the hard disk for high-level format

19

Partitioning divides the.....

hard disk into two or more partitions or makes it all one large partition

20

What command is partitioning performed with

FDISK or DISKPART

21

What does RAID stand for

redundant array of inexpensive disks

22

RAID does what?

combines multiple small, inexpensive disk drives into a group to yield performance exceeding that of one large, more expensive drive

23

What does RAID appear to the computer as?

As a single virtual drive

24

What does RAID support?

It supports fault-tolerance by redundantly storing information in various ways

25

what are the five types of array architectures and what the difference?

RAID 1-5
Different disk fault-tolerance
Different trade-offs in features and performance

26

A non-redundant array of disk drives is often referred to as

RAID 0

27

Which RAIDs are commonly used

Only RAID 0,1,3 and 5

28

Which raids do not offer any significant advantages over these other types

RAID 2,4

29

What is a parity check

An extra bit added to a byte to detect errors in storage or transmission

30

A single parity can only detect....

single bit errors since if an even number of bits are wrong then the parity bit will not change
