1.1 Systems Architecture

What does CPU stand for?

• Computer Processing Unit

• Central Power Unit

• Central Processing Unit

• Control Processing Unit

What is the main function of the CPU?

• Store data and information.

• Display output on the screen.

• Execute instructions and perform calculations

• Connect to the internet and browse websites.

Name two components of the CPU.

• memory unit

• input unit

• output unit

• control unit, ALU

What is the purpose of memory in a computer system?

• To provide power to the computer system.

• To display images and text on the screen.

• To connect the computer to the internet.

• To store and retrieve data and instructions for the computer's processor.

What are the two main types of memory in a computer system?

• RAM and ROM

• Input and Output

• CPU and GPU

• Cache and Hard Drive

What is cache memory and why is it important?

• Cache memory is used to store temporary files on a computer.

• Cache memory is only important for gaming computers.

• Cache memory is important because it helps to improve the overall performance of a computer system by reducing the time it takes to access data from the main memory.

• Cache memory is a type of storage device used to store large amounts of data.

What is the difference between RAM and cache memory?

• RAM is a type of computer memory used to store actively used data, while cache memory is a smaller and faster memory used to store frequently accessed data.

• RAM is a type of computer memory used to store data temporarily, while cache memory is a permanent storage for data.

• RAM is slower than cache memory in terms of data access speed.

• RAM and cache memory are the same thing, just called by different names.

What is the role of the control unit in the CPU?

• The control unit in the CPU coordinates and controls the operations of the CPU.

• The control unit in the CPU performs arithmetic and logical operations.

• The control unit in the CPU manages the input and output devices.

• The control unit in the CPU is responsible for storing data.

What is the purpose of the arithmetic logic unit (ALU) in the CPU?

• The ALU is used to control input and output devices in the CPU.

• The ALU is designed to execute instructions in the CPU.

• The ALU is responsible for managing memory in the CPU.

• The purpose of the ALU is to perform arithmetic and logical operations in the CPU.
