Computer Architecture Quiz

What is the main purpose of computer architecture?

• To define how hardware components communicate.

• To define how software components interact.

• To provide a user interface for applications.

• To organize the physical components of the computer.

Which component is responsible for executing instructions in a computer system?

• Memory

• ALU

• CPU

• I/O devices

The control unit (CU) is responsible for:

• Performing arithmetic operations.

• Fetching instructions from memory.

• Directing the operation of the CPU.

• Managing I/O operations.

Which of the following is NOT a part of computer architecture?

• CPU

• I/O devices

• Operating system

• Memory hierarchy

What is a bus in computer architecture?

• A communication pathway that connects components.

• A storage device for instructions.

• A type of CPU.

• A method of input/output communication.

What does the ALU (Arithmetic Logic Unit) perform?

• Fetching data

• Logical and arithmetic operations

• Controlling program execution

• Managing data storage

The program counter (PC) stores:

• The current instruction.

• The address of the next instruction to fetch.

• The execution results.

• Data being processed by the ALU.

What does the term "machine cycle" refer to?

• The time taken to execute one instruction.

• The number of instructions the CPU can execute per second.

• The process of fetching, decoding, executing, and storing an instruction.

• The speed of the CPU.

What is the main purpose of the system clock in a computer?

• To control the execution of instructions.

• To synchronize the operations of different components.

• To store data.

• To manage memory access.

Which of the following is the primary function of memory in a computer system?

• Storing data permanently.

• Storing data temporarily for quick access.

• Performing calculations.

• Fetching instructions.
