Explanation

Virtual reality (VR) uses software and hardware to create immersive, simulated environments.

It is different from artificial intelligence, which focuses on making machines think like humans.

Explanation

Analog data varies smoothly over time and is represented by continuous signals.

Examples include sound waves, temperature changes, and voltage variations.

Explanation

A software engineer designs, develops, tests, and maintains software using various programming languages.

Tasks like creating graphics, networking, or database security can be part of the job, but core work is coding and software development.

Explanation

External cache memory (like L2 or L3 cache) is placed between the CPU (microprocessor) and RAM to speed up data access.

It stores frequently used instructions/data to reduce the time the CPU waits for RAM.

Explanation

Modern microprocessors contain billions of transistors for processing instructions.

RAM, ROM, and hard disks have far fewer transistors compared to a CPU.

Explanation

An unwanted signal that mixes with the original signal is called noise.

Noise is any random or unwanted signal that interferes with the intended communication signal, potentially distorting or corrupting the original information.

Explanation

Mbps = Megabits per second

Gbps = Gigabits per second

Tbps = Terabits per second

Hbps is not a standard data transfer speed unit.

Explanation

Wrap Text is part of the Format or Layout tools for arranging text around objects, not the Page Setup group.

Margin, Orientation, and Size are all options found in the Page Setup group in MS Word.
