Unit 8.2 (Computer Hardware): A lovely quiz about the CPU!

This component will fetch, decode and execute data and instructions.

• CPU
• RAM
• Hard drive
• ROM

This component will store the applications and data you are currently using.

• CPU
• RAM
• Hard drive
• ROM

This stores all of the files needed for your computer system to run. For example, the operating system, programs and files.

• CPU
• RAM
• Hard drive
• ROM

Google Chrome and Microsoft Word are examples of

• Programs
• Operating systems
• Files

Documents, spreadsheets and presentations are examples of

• Programs
• Operating systems
• Files

The amount of times your CPU can complete the fetch-decode-execute cycle is known as

• The clock speed
• The number of cores
• The cache
• The RAM

The number of independent processors in your CPU is known as

• The clock speed
• The number of cores
• The cache
• The RAM

The area of the CPU which stores regularly used data is known as

• The clock speed
• The number of cores
• The cache
• The RAM

The more cache your CPU has…

• The less time spent accessing memory, therefore programs run faster
• The more time spent accessing memory, therefore programs run slower.

A dual core processor will

• Have 2 processors which perform the fetch, decode, execute cycle simultaneously. This makes it twice as fast.
• Have 2 processors which perform the fetch, decode, execute cycle simultaneously. This means more instructions can be carried out at once, making it faster.
• Have 4 processors which perform the fetch, decode, execute cycle simultaneously. This makes it twice as fast.
• Have 4 processors which perform the fetch, decode, execute cycle simultaneously. This means more instructions can be carried out at once, making it faster.
