Explanation

Software piracy is the illegal copying, distribution, or use of software without proper licensing.

It especially refers to unauthorized commercial resale or use of software for profit.

Explanation

Twisting copper wires (as in twisted pair cables) helps cancel out electromagnetic interference from external sources and reduces crosstalk between adjacent wires.

This method improves signal quality in data transmission.

Explanation

Dividing a number by zero is a logical error because the program may compile successfully but give a runtime error or unexpected behavior.

It represents a flaw in the program's logic.

Explanation

In Ring topology, each computer is connected to two others, forming a circle.

Data travels in one direction (or sometimes both, in a dual ring) from node to node until it reaches its destination.

Explanation

A telephone line supports full-duplex transmission, meaning both parties can talk and listen simultaneously.

Unlike half-duplex (e.g., walkie-talkie).

Full-duplex allows two-way communication at the same time.

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

Infrared communication supports data transfer rates typically ranging from 100 Kbps to 4 Mbps.

It is used in short-range, line-of-sight applications like remote controls and some wireless devices.

Explanation

Coaxial cables typically support data transmission speeds between 10 Mbps to 200 Mbps, used in cable TV and internet.

They are shielded and suitable for medium-speed data over longer distances than twisted-pair cables.

Explanation

In asynchronous transmission, data is sent one byte at a time with start and stop bits, and often a parity bit for error checking.

It's commonly used in serial communication, like keyboards and older modems.

Explanation

The first successful GUI-based computer was the Apple Lisa, developed by Apple Inc. in 1983.

It introduced a mouse-driven interface with icons and windows, paving the way for modern operating systems.
