A processor does the following

• Process data
• Execute instructions
• Execute data
• Operate in Hz

The part of a processor in which instructions are executed is known as?

• Core
• Centre
• Execution
• Instruction centre

What acts as an intermediary between the processor and the main memory? (6-9) ü

• Bus
• User
• Cache
• Clock

What is held in cache?

• All the programming instructions
• Commonly used instructions and data
• Instructions that have been processed
• Data that hasn’t been used for a long time

This would perform an operation such as 5+8 ?

• Arithmetic Logic Unit
• Accumulator
• Cache
• Control Unit

What is held in ROM?
