1. What is a Computer?

A computer is an electronic device that processes data and performs tasks according to a set of instructions called a program. It can store, retrieve, and process data, making it a versatile tool for a wide range of applications.

2. What is the Central Processing Unit (CPU)?

The CPU is the brain of the computer, responsible for executing instructions from programs. It performs arithmetic and logical operations, controlling the overall operation of the computer.

3. Explain the Difference Between RAM and ROM.

RAM (Random Access Memory) is volatile memory used for temporary data storage during program execution. It loses its contents when the power is turned off. In contrast, ROM (Read-Only Memory) is non-volatile and retains data even when the power is off, typically storing firmware and essential system instructions.

4. What is an Operating System?

An operating system is software that manages computer hardware and provides services for computer programs. It acts as an intermediary between the user and the computer hardware, facilitating communication and resource management.

5. Define Input and Output Devices.

Input devices are used to provide data and control signals to the computer (e.g., keyboard, mouse), while output devices display or produce results (e.g., monitor, printer).

6. Explain the Binary System.

The binary system is a base-2 number system used in computers, consisting of only 0s and 1s. It is the fundamental language of computers, as digital circuits can represent two states (on/off, 0/1) easily.

7. What is a File System?

A file system organizes and manages data on storage devices. It defines how data is stored, retrieved, and organized on a storage medium such as a hard drive or SSD.

8. Differentiate Between Hardware and Software.

Hardware refers to the physical components of a computer, such as the CPU, memory, and peripherals. Software, on the other hand, is a collection of programs and data that instruct the hardware to perform specific tasks.

9. Explain the Concept of Networking.

Networking involves connecting computers and other devices to share resources and information. The Internet is a global network that allows communication and information exchange across the world.

10. What is Cybersecurity?

Cybersecurity is the practice of protecting computer systems, networks, and data from unauthorized access, attacks, and damage. It encompasses a range of technologies, processes, and practices designed to safeguard digital information.

Conclusion:

These fundamental questions touch upon key aspects of computer science and technology. Whether you’re a beginner or an experienced professional, revisiting these basics is essential for building a strong foundation in the ever-evolving world of computing. Keep exploring, learning, and staying informed to stay ahead in the dynamic field of computer science.
