Final answer:

The response outlines the essential components of computers, including hardware, input/output devices, and memory types. It discusses the differences between RAM and ROM and explains computer viruses and their prevention methods. Various troubleshooting tips for common issues like sound, keyboard, and mouse problems are also provided.


Explanation:

1. Hardware Component of a Computer

The hardware component of a computer refers to the physical parts that make up a computer system, including the CPU, memory, storage devices, and input/output devices.

2. Computer Peripherals

Computer peripherals are external devices connected to the computer that expand its functionality. Examples include printers, scanners, and external drives.

a. Input Devices

Input devices allow users to input data into a computer. Some common input devices include:

  1. Keyboard
  2. Mouse
  3. Scanner
  4. Microphone

b. Output Devices

Output devices display or produce data from a computer. Four examples of output devices are:

  1. Monitor
  2. Printer
  3. Speakers
  4. Projector

3. Computer Memory

Computer memory refers to storage that enables computers to store and retrieve data quickly. The smallest unit of data in a computer is a bit.

Types of Memory

Different types of memory include:

  • RAM (Random Access Memory)
  • ROM (Read-Only Memory)

b. Secondary Storage Devices

Examples of secondary storage devices are:

  • Hard Disk Drives (HDD)
  • Solid State Drives (SSD)

4. RAM and ROM

a. RAM

RAM is a type of volatile memory that temporarily stores data for fast access while a computer is in use. It is essential for computer performance, as it allows for quick read and write operations.

b. ROM

ROM is a non-volatile memory that permanently stores data, typically instructions needed during the boot process. Unlike RAM, the data in ROM is not lost when the computer is turned off.

5. Storage Conversion

To convert 10TB to GBs, you multiply by 1024.

10 TB is equal to 10240 GB.

6. Computer Abbreviations

a.

Full forms of the abbreviations are:

  • Computer: Common Operating Machine Particularly Used for Trade, Education, and Research
  • EBCDIC: Extended Binary Coded Decimal Interchange Code
  • ASCII: American Standard Code for Information Interchange

b.

Full forms include:

  • LCD: Liquid Crystal Display
  • CRT: Cathode Ray Tube
  • NIC: Network Interface Card

c.

Full forms include:

  • VLSI: Very Large Scale Integration
  • LSI: Large Scale Integration
  • ICs: Integrated Circuits
  • ALU: Arithmetic Logic Unit

7. Computer Virus

A computer virus is malicious software designed to replicate and spread. Viruses can corrupt data, slow down performance, and cause operational failures.

a.

Prevention methods include:

  • Installing antivirus software
  • Regularly updating software and operating systems

b.

No single person "owns" computer viruses; they often originate from anonymous sources or are developed by individuals with malicious intent.

c. Troubleshooting Tips

For troubleshooting sound, keyboard, and mouse issues, consider:

  • Checking connections and cables
  • Restarting the computer
  • Updating drivers
  • Testing with another device if possible
