Year 7 Computing Revision

What is the CPU?

• All the physical parts of a computer

• Software that allows all programs and applications to run

• Hardware inside a computer that carries out program instructions by performing arithmetic and logical operations

Which one does this: Manages programs by controlling data between the CPU and other devices.

• CU (Control Unit)

• ALU (Arithmetic and Logic Unit)

Which one does this: Carries out comparisons and determines the relationship between values and logical operations

• CU (Control Unit)

• ALU (Arithmetic and Logic Unit)

Which one does this: Receives coded instructions to complete calculations or operations.

• CU (Control Unit)

• ALU (Arithmetic and Logic Unit)

Which one does this: Controls and instruction register that can transfer instructions or data.

• CU (Control Unit)

• ALU (Arithmetic and Logic Unit)

Name the cycle that the CPU performs

• Decode, Fetch, Retrieve Cycle

• Fetch, Decode, Execute Cycle

• Retrieve, Decode, Execute Cycle

• Fetch, Decipher, Execute Cycle

What language does the CPU understand?

• English

• Binary

• French

• Denary

What is the CPU's main memory called?

• Delayed Access Store

• Immediate Access Store (IAS)

• Fetch Access Store

• Managed Access Store

What does the fetch stage of the cycle do?

• Store data and instructions from main memory in temporary memory (called registers)

• Carry out instructions and store the results

• Make sense of instructions and prepare the data

What does the decode stage of the cycle do?

• Store data and instructions from main memory in temporary memory (called registers)

• Carry out instructions and store the results

• Make sense of instructions and prepare the data
