Explanation

Primary storage, also known as main storage or memory.

It is the area in a computer in which data is stored for quick access by the computer's processor.

The terms random access memory (RAM) and memory are often as synonyms for primary or main storage.

Explanation

RAM is a primary memory while ROM is a secondary memory.

RAM stands for: Random Access Memory

ROM stands for: Read Only Memory

Explanation

CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) are used together to design and produce products.

This technology improves accuracy, efficiency, and automation in manufacturing.

Explanation

Communication between a keyboard and computer is simplex, meaning data flows in one direction only — from keyboard to computer.

The computer does not send data back to the keyboard during typing.

There are 3 main data transmission modes:

1. Simplex: Data flows in one direction only (e.g., keyboard to computer).
2. Half-Duplex: Data can flow both ways, but not at the same time (e.g., walkie-talkies).
3. Full-Duplex: Data flows both ways simultaneously (e.g., telephone conversations).

Explanation

A warm boot refers to restarting a computer without turning off the power (e.g., using Ctrl + Alt + Del or the restart option).

In contrast, a cold boot means starting the computer after it has been completely powered off.

Explanation

A switch connects two or more computers within the same local area network (LAN).

It intelligently forwards data only to the specific device intended, improving network efficiency.

Explanation

John Bardeen, William B. Shockley, and Walter H. Brattain are collectively known as the fathers of the second generation of computers.

They invented the transistor in 1947, which led to the development of smaller, faster, and more efficient computers.

The fathers of each generation of computers:

1. First generation (Vacuum Tubes): John Atanasoff (invented the first electronic computer, ABC)
2. Second generation (Transistors): John Bardeen, William B. Shockley, and Walter H. Brattain (invented the transistor)
3. Third generation (Integrated Circuits): Jack Kilby (developed the first integrated circuit)
4. Fourth generation (Microprocessors): Ted Hoff and Stanley Mazor (developed the first microprocessor, Intel 4004)

Explanation

Drivers are programs that control the hardware of a computer.

It allowing the operating system and other software to interact with the hardware devices.

They act as a bridge between the hardware and software, providing instructions on how to operate the hardware devices.

Explanation

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell,

usually consisting of a tiny capacitor and a transistor,

both typically based on metal-oxide-semiconductor (MOS) technology.

DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs)

Explanation

Transmission means sending or passing on data or signals.

The opposite (antonym) is Hold, which means to keep or retain without sending.

Transmission means ڈیٹا یا سگنل بھیجنا یا پاس کرنا

Hold means بھیجے بغیر رکھنا یا برقرار رکھنا
