Explanation

Dot pitch (also known as pixel pitch) is the distance between two same-colored pixels on a screen.

A smaller dot pitch means a sharper and clearer display quality.

Explanation

Blu-ray disk is a type of optical storage that uses laser technology to read and write data.

It stores high-definition video and large data.

Unlike floppy disks and hard disks which are magnetic storage devices.

Explanation

Feature Virtual Memory

Location: On the hard drive or SSD

Speed: Slower (due to disk I/O operations)

Capacity: Larger, limited by disk space

Cost: Lower (cost of additional disk storage)

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

Bluetooth is a short-range radio communication technology used for exchanging data over short distances (typically up to 10 meters).

It enables wireless connection between devices like phones, headsets, and computers.

Explanation

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

In computing, jobs in the buffer are typically managed in a queue, where they wait their turn for processing.

A queue follows the First-In-First-Out (FIFO) method, ensuring orderly job execution.

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

Pixel is short for "picture element".

It is the smallest unit of a digital image.

Each pixel holds color and brightness data, combining to form the full picture.

Explanation

 Function overloading allows multiple functions with the same name but different parameters.

It is a type of compile-time polymorphism, enabling code flexibility and readability.
