Computer Architecture Quiz

What does IAS stand for?

• Immediate Access Store (Same as RAM)

• Integrated Access System

• Intelligent Application Suite

• Interactive Application Service

What is the function of a von Neumann architecture?

• It controls the power supply of a computer.

• It introduced the concept of the stored program.

• It is responsible for the design of integrated circuits.

• It manages the data flow between the CPU and memory.

Which register is responsible for storing numerical values during an operation?

• Memory Address Register (MAR)

• Current Instruction Register (CIR)

• Memory Data Register (MDR)

• Accumulator (ACC)

What does a system clock do?

• It controls the power supply of a computer.

• It produces timing signals for synchronization.

• It manages the data flow between the CPU and memory.

• It stores the address of the next instruction to be read.

What is the purpose of backing store?

• To hold frequently used data for quick access.

• To store data permanently even when the computer is powered down.

• To manage the synchronization of data flow.

• To convert digital data into electric currents.

What is the main function of a register in the CPU?

• To store data permanently.

• To convert digital data into electric currents.

• To hold data or instructions as part of the Fetch–Decode–Execute cycle.

• To manage memory addresses.

What is the difference between a unidirectional and bidirectional data flow?

• Unidirectional can travel in one direction, bidirectional in both.

• Unidirectional is faster than bidirectional.

• Bidirectional is used for data, unidirectional for control signals.

• Unidirectional is used for control signals, bidirectional for data.

What is overclocking?

• Reducing the clock speed of a system clock.

• Changing the clock speed to a lower value.

• Changing the clock speed to a higher value.

• Replacing the system clock with a new one.

How many cores does a dual core CPU have?

• One core

• Two cores

• Four cores

• Eight cores

What is the Fetch–Execute–Decode cycle?

• Instructions and data are fetched, decoded, and finally executed.

• Instructions and data are decoded, fetched, and finally executed.

• Instructions and data are executed, fetched, and finally decoded.

• Instructions and data are fetched, executed, and finally decoded.
