Class 8 Computer Questions With Answers

1. What is the purpose of an operating system?

Ans: An operating system (OS) is software that manages computer hardware and provides services for computer programs. Its primary purpose is to act as an intermediary between the user and the computer hardware, enabling users to interact with the computer system and run various software applications. The OS also handles tasks like memory, file, and device management.

2. Define RAM and ROM in relation to computer memory.

Ans: RAM (Random Access Memory) and ROM (Read-Only Memory) are types of computer memory:

• RAM: RAM is a volatile memory that stores data currently being used or processed by the computer. It allows quick access to data, but its contents are lost when the computer is turned off. RAM is crucial for running programs and multitasking.
• ROM: ROM is a non-volatile memory that contains firmware and permanent instructions necessary for booting up the computer and initializing hardware components. It retains data even when the computer is powered off and is not easily modified by users.

3. What is a file extension?

Ans: A file extension is a suffix at the end of a filename that indicates the format or type of the file. It helps both the user and the computer to identify the nature of the file and the software required to open or process it. For example, “.txt” indicates a plain text file, “.jpg” represents a JPEG image file, and “.docx” is associated with Microsoft Word documents.
