FAQs on Components of Computer System Video Lecture - SSC CGL Tier 2 - Study Material, Online Tests, Previous Year

1. What are the main components of a computer system?
Ans. The main components of a computer system include the central processing unit (CPU), memory (RAM), storage devices (hard drive or SSD), input devices (keyboard and mouse), and output devices (monitor or printer). These components work together to process and store data, allowing the computer to perform tasks.
2. What is the function of the central processing unit (CPU)?
Ans. The central processing unit (CPU) is often referred to as the "brain" of the computer system. Its main function is to carry out instructions and perform calculations. The CPU interprets and executes instructions from the computer's memory, manages data flow between different components, and performs arithmetic and logical operations.
3. How does memory (RAM) contribute to the computer system?
Ans. Random Access Memory (RAM) is a vital component of a computer system. It stores data and instructions that are being actively used by the CPU. When a program is running, it loads data from the storage devices into RAM for faster access. The CPU can quickly retrieve and modify data in RAM, allowing for efficient and speedy operations.
4. What are storage devices and their role in a computer system?
Ans. Storage devices in a computer system, such as hard drives or solid-state drives (SSD), play a crucial role in data storage. They provide long-term storage for operating systems, software applications, files, and user data. Storage devices retain data even when the computer is turned off and allow for easy retrieval and access when needed.
5. What are input and output devices, and why are they important in a computer system?
Ans. Input devices, such as keyboards and mice, enable users to provide instructions and data to the computer system. Output devices, like monitors and printers, display or produce the results of the computer's processing. These devices are essential for human-computer interaction, allowing users to interact with and receive information from the computer system.
