Explanation

getche() reads a single character from the keyboard and displays (echoes) it immediately on the screen.

It's part of conio.h in C programming, often used for interactive input.

Explanation

The <sup> tag in HTML is used to define superscript text, which appears slightly above the normal line (e.g., x²).

Commonly used for mathematical exponents and footnote references.

Explanation

The Interface Message Processor (IMP) was the first device used to connect computers in the early ARPANET, the precursor to the internet.

It acted like a packet-switching node, similar to modern routers.

Explanation

Flowcharts help visualize the logic and flow of an algorithm.

They are useful for spotting errors, inefficiencies, or missing steps before coding.

Explanation

Resolution is commonly measured in pixels per inch (PPI) or dots per inch (DPI) for screens and printed images.

Higher PPI/DPI means better image clarity and detail.

Explanation

Nested loops are loops placed inside another loop.

It allowing complex iteration through multi-dimensional data structures.

They are commonly used for tasks like processing matrices or multi-level data.

Explanation

Edge computing involves processing data closer to where it is generated, such as on IoT devices or local servers, reducing latency and bandwidth use.

It enables faster data processing and real-time analytics without needing to send data to a centralized cloud server.

Explanation

LiFi (Light Fidelity) uses light waves, typically from LED lights, to transmit data at high speeds.

It offers faster data transfer rates compared to traditional Wi-Fi due to the high frequency of light waves.

Explanation

• RAM is a type of Primary Memory.
• Also known as Volatile Memory.
• Also called Read/Write Memory.
• Temporarily stores data and instructions.
• Allows data to be read and written.
• Stores data currently used by the CPU.

Explanation

The CPU and memory are located on the motherboard.

The motherboard's job is to connect all hardware components together.

The motherboard's a thin plate that holds the:

1. CPU,
2. Memory,
3. Connectors for the hard drive,
4. Optical drives.
