Explanation

A number system that has eight different symbols to represent any quantity is known as Octal.

The Octal number system uses digits from 0 to 7.

It is often used in computing as a simpler alternative to binary representation.

Explanation

Seek time is defined as the time taken to position the read/write head over the correct track on a disk.

It is a crucial factor in the performance of hard drives and other storage devices.

Explanation

A modem's purpose is to convert digital information to analog signals (modulation), and to convert analog signals back into useful digital information (demodulation).

MODEM stands for Modulation and Demodulation.

Explanation

Shortwave radio operates in the high frequency (HF) band, typically between 3 MHz and 30 MHz.

The range 5.9 MHz to 26.1 MHz is commonly used for long-distance communication like international broadcasting.

Explanation

Fiber optics uses light to transmit data at high speeds through thin glass or plastic fibers.

It is mainly used in communication networks like internet, telephone, and cable TV.

Explanation

Artificial Intelligence, Cloud Computing, and Zero-Knowledge technologies are all part of the broader field of IT.

Artificial Intelligence (AI)

Definition: The simulation of human intelligence by machines.

Cloud Computing

Definition: Delivery of computing services (servers, storage, databases, etc.) over the Internet.

Zero-Knowledge (ZK)

Definition: A cryptographic method where one party proves to another that something is true without revealing the actual information.

Explanation

Relational operators (like >, <, ==) are used to compare two values.

They return true or false based on the comparison result.

Explanation

Third generation computers (1960s–70s) used integrated circuits (ICs), enabling them to execute instructions in millionths of a second.

This marked a significant improvement in speed and processing over earlier generations.

Explanation

A linker combines object files and library files into a single executable file.

It resolves references between different modules and links external libraries needed for execution.

Explanation

Digital media is used to transmit information in the form of binary data (0s and 1s) in electronic devices.

It includes texts, images, audio, and video transmitted through digital signals.
