Multiple Choice

One core of CPU is equivalent to how many cycles of Fetch-Decode-Execute process?

• 1

• 2

• 3

Multiple Choice

Core is made up of ______________.

• MDR, registers, and ALU

• PC, MAR, MDR

• registers, ALU, CU

• PC, ALU, and CU

Multiple Choice

 More number of cores require _________ clock speed.

• lower

• higher

Multiple Choice

If a computer has 4 cores, it means that it has _____ channels.

• 2

• 4

• 6

• 8

​CORE

The part of the CPU that contains all the components that are used to perform the fetch-decode-execute cycle​

• ​one core = one fetch-decode-execute cycle

• ​made up of ALU, control unit, and registers

• ​more number of core needs higher clock speed

• ​core communicates with each other, creating channels

Multiple Choice

 The number of FDE cycles that can be performed in a second. 

• Cache

• Clock Speed

• Core

Multiple Select

Another term for clock speed.

• system clock

• internal clock

Multiple Choice

Unit used for clock speed.

• MB

• hertz

• mL

• hP

Multiple Choice

1 hertz is equivalent to _______ instruction per second.

• 1

• 2

• 1000

• 16

Multiple Choice

Clock speed synchronises computer operations through _________.

• address bus

• control bus

• data bus

• purple bus

• CLOCK SPEED​

​The number of FDE cycles that can be performed in a second

• ​a.k.a internal clock

• 1 hertz = one instruction per second

• Synchronises computer operations through control bus​

Multiple Choice

A type of storage that is built into the CPU, to store the most frequently used data and instructions.

• Cache

• Clock Speed

• Core

Multiple Choice

Cache makes the fetching of the data ________.

• faster

• slower

Multiple Choice

Cache is last checked by the CPU for any instructions to be fetched.

• TRUE

• FALSE

​Cache

​A type of storage that is built into the CPU, to store the most frequently used data and instructions

• Makes the fetching of data quicker (the faster the CPU fetches the instructions, the better performance)

• CPU checks cache first for any instructions to be fetched
