What is a Computer System made up of?
Correct Answer
C. Hardware and Software
Explanation
A computer system is made up of both hardware and software components. Hardware refers to the physical components of a computer system, such as the system unit, peripherals, and input/output devices. Software, on the other hand, refers to the programs and instructions that are installed on the computer system, including both system software (such as the operating system) and application software (such as word processors or web browsers). Therefore, both hardware and software are essential components of a computer system.

3.
What does open-source software mean?
Correct Answer
A. Free software with no restrictions
Explanation
Open-source software is freely accessible and allows users to view, modify, and distribute the source code. It promotes collaboration, transparency, and community-driven development without imposing restrictions on usage.
4.
Which is an example of an Input device?
Correct Answer
B. Keyboard
Explanation
A keyboard is an example of an input device because it allows the user to input data and commands into a computer system. It consists of a set of keys that are used to type letters, numbers, and symbols. The keyboard sends the input to the computer, which processes the information and performs the desired actions. In contrast, a printer, CPU, and memory are not input devices as they do not directly receive data from the user.
5.
Which is an example of an Output device?
Correct Answer
A. Printer
Explanation
An example of an output device is a printer. A printer is used to produce a hard copy of documents or images that are stored electronically. It takes data from a computer or other device and transfers it onto paper or other physical media. Unlike a keyboard or CPU, which are input and processing devices respectively, a printer is specifically designed to generate output in the form of printed documents.
6.
Which component is responsible for long-term data storage in a computer?
