Question 1

________boosts a CPU's performance by working on more than one instruction at the same time.

Accepted Answer

The answer of ________boosts a CPU's performance by working on...

Question 2

The CPU is the part of the ALU that performs mathematical operations and makes comparisons.

Accepted Answer

The ALU (Arithmetic Logic Unit) is a part of the CPU that performs mathematical operations and makes comparisons, not the other way around.

Question 3

Today's clock speeds are measured in megahertz (MHz).

Accepted Answer

Today's clock speeds are measured in gigahertz (GHz), not megahertz (MHz).

Question 4

The ________ processor is used in tablet computers and smartphones because it is very small and uses very little power.

Accepted Answer

The answer of The ________ processor is used in tablet...

Question 5

All data input into a computer will be stored as 0s and 1s.

Accepted Answer

This statement is true. Computers use binary code, which consists of 0s and 1s, to store and process data.

Question 6

The CPU machine cycle starts with the Fetch step.

Accepted Answer

The CPU machine cycle starts with the Fetch step, where the processor retrieves an instruction from memory.

Question 7

Level 1 cache is located farther away from the CPU than Level 3 cache.

Accepted Answer

Level 1 (L1) cache is the closest and fastest cache in the hierarchy of caches and is located next to the CPU. On the other hand, Level 3 (L3) cache is typically the farthest and slower cache, located further away from the CPU.

Question 8

The collection of commands that a CPU executes is called the instruction set.

Accepted Answer

The instruction set is a collection of commands that a CPU can understand and execute.

Question 9

________ is the final step of the CPU machine cycle.

Accepted Answer

The answer of ________ is the final step of the...

Question 10

A single byte is composed of ten bits.

Accepted Answer

A byte is composed of eight bits, not ten.

Question 11

The ASCII code is able to represent the alphabets of all modern and historic languages.

Accepted Answer

The ASCII code only represents a limited set of characters including alphabets (upper and lower case), digits, and some special characters. It cannot represent characters used in non-Latin languages such as Chinese, Japanese, Arabic, etc.

Question 12

Mainstreaming boosts CPU performance by enabling the CPU to work on more than one processing stage at a time.

Accepted Answer

The answer of Mainstreaming boosts CPU performance by enabling the...

Question 13

Mathematical operations and comparisons are performed in the ________.

Accepted Answer

The answer of Mathematical operations and comparisons are performed in...

Question 14

A semiconductor is any material that can be controlled to either conduct electricity or prohibit the flow of electricity.

Accepted Answer

A semiconductor is a type of material that can be controlled to either allow or block the flow of electricity. This property makes it useful in electronic devices such as transistors and diodes.
