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.

Explanation

3D Paint (also known as Paint 3D) was introduced with the Windows 10 Creators Update in 2017.

It allows users to create and edit both 2D and 3D graphics.

Explanation

When a computer detects invalid data, it often displays a red triangle or an error indicator to alert the user.

This symbol is commonly used in spreadsheets, databases, and other software applications to indicate that the data is incorrect, inconsistent, or outside of the expected range.
