Explanation

An array is considered a composite data type because it can hold multiple values of the same type in a single variable.

Each value is accessed by an index, and arrays can be used to store collections of related data

Explanation

Iteration refers to the process of repeatedly executing a set of instructions or statements in a loop.

It is used to perform the same operation multiple times, such as in loops like for, while, and do-while.

Additional information::

Recursion involves a function calling itself,

 Conditional statements and function calls serve different purposes in programming.

Explanation

An expression in programming is a combination of variables, constants, operators, and functions that are evaluated to produce a value.

It can range from simple arithmetic operations to complex calculations involving multiple elements.

Explanation

The HTML code <input type="checkbox"> is used to create a checkbox input field. This allows users to select or deselect options by checking or unchecking the box.

Explanation

 Both Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) cables use twisted pairs of copper wires to transmit data.

The primary difference is that STP cables have additional shielding around the wires to protect against electromagnetic interference

Whereas UTP cables do not have this extra shielding

Explanation

Packet switching is used in networks where data is broken into smaller packets before being transmitted.

These packets are sent independently and may take different paths to the destination

This method is efficient and robust, making it the foundation for most modern data networks, including the Internet.

Explanation

Modern computers are primarily based on transistor technology. 

And old computers are based on vacuum tube

John Vincent Atanasoff invented the first digital computer in 1930. 

Charles Babbage is known as the Father of the Computer.

Explanation

 Computers store data and instructions using binary digits, also known as bits.

Binary digits are represented as 0s and 1s

They are the fundamental building blocks of all data and instructions in digital computing.

Explanation

 The code ')A1B2' follows a specific format

Where it begins with a special character (alpha), followed by a numeric digit, a letter, and another numeric digit.

The correct option that matches this format is ')A1B2'.

Explanation

 In C++, when you use a statement like StructName var;,

it tells the compiler to allocate memory for an instance of the structure StructName.
