What is the role of an input device in a computer system?

• Converts binary data into real-world information

• Stores binary data on the computer

• Converts real-world information to binary data

• Changes the data by following an algorithm

Answer explanation

An input device in a computer system converts real-world information to binary data, allowing the computer to process and manipulate the data effectively.

What is meant by the Von Neumann Architecture?

• A type of computer system that uses binary data

• The basic concept of a computer system introduced in 1945

• A modern computer system that does not follow the basic principles

• The idea that a computer should only perform one task

Answer explanation

The Von Neumann Architecture refers to the basic concept of a computer system introduced in 1945, which includes a CPU, memory, input/output devices, and a control unit.

What does the stored program concept allow in modern computers?

• It allows the computer to store binary data only.

• It allows the computer to perform tasks without changing the program.

• It allows the computer to change what it does by changing the stored program.

• It prevents the computer from performing different tasks.

Answer explanation

It allows the computer to change what it does by changing the stored program.
