Explanation

High-level programming languages are commonly classified into three categories: procedural, object-oriented, and functional.

These categories are based on different programming paradigms that define how programmers structure and write code.

Explanation

L3 cache is a level of CPU cache memory that is slower than L1 and L2, but still faster than main RAM.

It helps improve overall CPU performance by storing frequently accessed data shared across cores.

Explanation

A mechanical mouse uses a rubber ball to detect movement as it rolls on a surface.

The movement of the ball turns internal rollers that track the cursor’s direction and speed.

Explanation

The ALU is the main processing unit of a CPU, responsible for performing all arithmetic and logical operations.

It works alongside other components like registers and cache to execute instructions efficiently.

Explanation

The term information highway refers to the Internet, which is a global system that allows access to vast amounts of information.

Intranet is a private network within an organization, and computer refers to the device used to access the Internet.

Explanation

In C programming, && is the logical AND operator, used to evaluate whether both conditions are true.

It differs from &, which is a bitwise AND operator.

Explanation

gets() can accept a full string including white space characters until a newline is encountered.

In contrast, getch() and getche() only accept a single character input.

Explanation

HTML provides 6 levels of heading tags: <h1> to <h6>, with <h1> being the largest and most important.

These tags are used to define headings and organize content hierarchically on web pages.

Explanation

Thinking is not a computer operation because computers do not possess consciousness or reasoning like humans.

Computers perform Input, Processing, Storage, and Output, but they follow pre-defined instructions.

Explanation

ROM (Read-Only Memory) is non-volatile.

This meaning it retains data even when the power is turned off.

RAM is volatile.
