Commonly used instructions can be quickly accessed from from the RAM(main memory) so less time is spent scanning the surface of the Hard Disk Drive.

c)

The CPU requires a steady supply of electrical current, and the Cache acts as a kind of well for this. By having a larger Cache, it means your computer can function for longer between small electrical power-outs.

d)

A larger Cache means that the CPU has almost a second form of RAM and this means twice as many instructions can be fetched, decoded and executed per cycle.

140.

What is clock speed?

a)

The number of cycles per second, measured in Hertz (Hz).

b)

The speed with which the computer clock(the one that tells the time in the bottom right hand corner) is refreshed.

c)

The speed with which an individual instruction can be passed from RAM to the Memory Data Register.

d)

The number of bits (1s and 0s) that can be processed per second, measured in Hertz (Hz).

e)

The number of nibbles that can be processed per second, measured in Kilohertz (Hz).

141.

The faster the clock speed...

a)

The more instructions can be fetched, decoded and executed in a given period of time.

b)

The easier it is to time the completion of a particular task by the CPU.

c)

The greater the chance of the CPU being overclocked and potentially being damaged.

d)

The less threads the CPU will be dealing with at any given moment in time.

142.

A cycle is...

a)

Fetching, decoding and executing an instruction.

b)

Copying data from the accumulator and sending it back to the RAM (primary memory).

c)

Storing, decoding and fetching an instruction

d)

Thirty two 1s and 0s being stored in the registers of the CPU, ready to be processed.

143.

Multiple cores are...

a)

Architecture where a single control unit works with several cores (the bits of a processor that actually carry out the instructions).

b)

Architecture where several control units work with more than one core (the bits of a processor that actually carry out the instructions).

c)

Architecture where there is more than one processor. Each processor is given its own dedicated chip of primary memory (RAM), to prevent data collisions.

d)

Is actually a misleading phrase. It actually means more than one control unit working with a single core(the bit of a processor that actually carry out the instructions).

144.

A Dual Core Processor improves performance by...

a)

Each core simultaneously processing instructions (so the time required is almost halved).

b)

One core can work faster on a task because there is a redundant processor not having to be managed by the Control Unit.

c)

Each core is designed to be significantly quicker so together they will process more together.

d)

Bottlenecks of data are removed from the processor bus because they are being passed directly into each code.

145.

The Program Counter

a)

Stores the address of the next instruction in memory

b)

Stores the address of where the next item will be fetched from

c)

Stores data fetched from memory, or waiting to be stored in memory

d)

Stores the result of arithmetic calculations

146.

Memory Address Register (MAR)

a)

Stores the address of the next instruction in memory

b)

c)

Stores data fetched from memory, or waiting to be stored in memory

d)

Stores the result of arithmetic calculations

147.

Memory Data Register (MDR)

a)

Stores the address of the next instruction in memory

b)

Stores the address of where the next item will be fetched from

c)

Stores data fetched from memory, or waiting to be stored in memory

d)

Stores the result of arithmetic calculations

148.

The control unit

a)

Controls the flow of data around the CPU and also decodes instructions

b)

Only controls the flow of data around the CPU

c)

Only decodes instructions

d)

Controls how much power is directed to all components within the computer

149.

Accumulator

a)

Stores the address of the next instruction in memory

b)

Stores the address of where the next item will be fetched from

c)

Stores data fetched from memory, or waiting to be stored in memory

d)

Stores the result of arithmetic calculations

150.

The Arithmetic Logic Unit (ALU)

a)

Carries out numerical calculations and logical decisions

b)

Calculates the different items of number data stored within the Accumulator and converts them into logical decisions

c)

Calculates graphic data as they are only found within GPU units.

d)

Calculates the flow of execution in a program and decodes instructions into small steps to be carried out by the program counter.
