The CPU is the brain of the computer. The processing power of the CPU depends on which of the 3 features below?

• Physical Size

• Number of Cores

• Cache Size

• Clock Speed

• Control Unit

What are the 4 main components of the CPU?

• RAM

• ALU

• Cache

• Registers

• Control Unit

Which part of the processor is responsible for managing the fetching, decoding, and executing of program instructions? It controls the flow of data inside the CPU to registers and outside the CPU to RAM.

• Register

• ALU

• Control unit

• Cache

It performs calculations and logical operations such as AND, OR, NOT.

• Registers

• ALU

• Cache

• Control Unit

A very fast type of memory which is used to store recently used data and instructions so that the CPU can access it quickly the next time it is needed. It has very low capacity.

• Cache

• Registers

• Control Unit

• ALU

An extremely fast type of temporary storage on the CPU used to store small amounts of data that are needed during processing.

• Resgister

• ALU

• MAR

• Chache

A system where both the instructions and data are stored in memory so that they can be accessed by the CPU is called?
