Explanation

• A computer cannot ‘boot’ if it does not have the Operating System.
• *****
• An operating system is system software that handles software and hardware resources and gives services to computer programs.
• The computer system requires an operating system for “boot”
• ****
• A Loader in the computer systems is a unit of the operating system which is primarily responsible for loading the libraries and programs.
• ****
  
• An assembler in the computer system is a program that interprets software programs written using “assembly language” into “machine language”.

Explanation

An IP address is a unique address that identifies a device on the internet or a local network.

IP stands for "Internet Protocol," which is the set of rules governing the format of data sent via the internet or local network.

Explanation

Hard disk storage devices can store a maximum amount of data.

It has the highest capacity to store data up to 2 Terabytes.

Hard Disk is an electromechanical data storage device that stores and retrieves digital data using magnetic storage.

Explanation

The main memory of a computer is also known by several names, including:

• Primary storage
• Internal memory
• Primary memory
• Main storage
• Random Access Memory (RAM)

All these terms refer to the computer's volatile memory, which temporarily stores data and programs that are currently being used or processed by the CPU (Central Processing Unit).

RAM is a primary memory.

ROM is a secondary memory.

RAM stands for: Random Access Memory

ROM stands for: Read Only Memory

Explanation

• RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS).

• RAM is also known as read/write memory.

Explanation

Short cut key to saving any document in MS office is Ctrl+S.

Explanation

A trackball is a pointing device where the ball is held in place by a socket, allowing users to rotate the ball to move the cursor on the screen.

Unlike a traditional mouse, which moves over a surface, a trackball stays stationary, and the ball's rotation controls the cursor's movement in different directions.

Explanation

A hard disk is a secondary storage device used to store data permanently.

RAM and ROM are primary storage (main memory).

Diodes and Semiconductors are basic electronic components.

Explanation

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.

The main electronic component used in first-generation counterparts was Vacuum Tubes and Valves.

Leo is called the first-generation computer.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation
