Answer Key with Explanations
1. Ans: B) CPU
Exp: The CPU (Central Processing Unit) controls all operations and calculations, hence it is called the brain of the computer. (CPU को कंप्यूटर का दिमाग कहा जाता है।)
2. Ans: A) Central Processing Unit
Exp: CPU stands for Central Processing Unit.
3. Ans: C) ALU (Arithmetic Logic Unit)
Exp: The ALU performs all mathematical (arithmetic) and logical (AND, OR, NOT) operations inside the CPU.
4. Ans: B) 8
Exp: 1 Byte consists of exactly 8 bits. (1 Byte = 8 bits).
5. Ans: C) RAM
Exp: RAM (Random Access Memory) is volatile, meaning it loses all its data when the computer is turned off. (बिजली जाने पर RAM का डेटा डिलीट हो जाता है।)
6. Ans: B) Read Only Memory
Exp: ROM stands for Read Only Memory. It is non-volatile and contains permanent boot instructions.
7. Ans: D) Scanner
Exp: A scanner inputs physical documents/images into the computer in digital form. Monitor, Printer, and Speaker are output devices.
8. Ans: B) Printer
Exp: A printer produces a physical (hard copy) output of documents stored on a computer.
9. Ans: A) Charles Babbage
Exp: Charles Babbage designed the Analytical Engine in the 1830s and is known as the Father of the Computer.
10. Ans: D) Vacuum Tubes
Exp: First-generation computers (1940-1956) used large vacuum tubes for circuitry.
11. Ans: B) 1024
Exp: In digital memory, 1 Kilobyte (KB) = 1024 Bytes.
12. Ans: D) Register
Exp: Registers are the smallest and fastest memory located directly inside the CPU, faster than Cache and RAM.
13. Ans: A) Basic Input Output System
Exp: BIOS is firmware used to perform hardware initialization during the booting process.
14. Ans: B) Application Software
Exp: These are end-user programs designed to perform specific tasks (like word processing or creating spreadsheets).
15. Ans: C) Operating System
Exp: An Operating System (OS) is system software that manages computer hardware and software resources. (Windows एक ऑपरेटिंग सिस्टम है।)
16. Ans: B) Hardware
Exp: Physical, tangible parts of a computer (like monitor, mouse, keyboard) are called hardware. (जिने हम छू सकते हैं वह Hardware है।)
17. Ans: C) Router
Exp: A router is a networking device that forwards data packets between computer networks, connecting multiple networks together.
18. Ans: C) CD-ROM
Exp: CD-ROM (Compact Disc Read-Only Memory) uses optical lasers to read and write data.
19. Ans: A) 2
Exp: The binary system uses only two digits: 0 and 1. (कंप्यूटर बाइनरी भाषा (0 और 1) समझता है।)
20. Ans: A) Universal Serial Bus
Exp: USB is an industry standard for cables and connectors used to connect devices to a computer.
21. Ans: B) Motherboard
Exp: The motherboard is the main printed circuit board (PCB) where all core components (CPU, RAM) are connected.
22. Ans: D) Touchscreen
Exp: A touchscreen acts as an input (receiving touch commands) and output (displaying visuals) device simultaneously.
23. Ans: B) Shift + Delete
Exp: Pressing Shift + Delete permanently deletes a file without moving it to the Recycle Bin.
24. Ans: B) Clock speed
Exp: GHz (Gigahertz) measures the clock speed of a CPU, indicating how fast the processor can execute instructions.
25. Ans: B) Malware Exp: Malware (Malicious Software) is designed to harm, exploit, or cause unauthorized access to a computer system. (वायरस एक मालवेयर है।)
