Explanation:

Program to convert KiloBytes to Bytes and Bits

Given Number of Kilobytes. The task is to Convert them into Bytes and Bits.

Bit: A Bit is the basic unit in computer information and has only two different values, normally defined as a 0 or 1. These values can be interpreted as on or off, yes or no, true or false, etc. It just depends on the binary code.

Add 1 bit, double the number of patterns.

1 bit – 2 patterns i.e 0 and 1

2 bits – 4 patterns i.e 00, 01, 10, 11

3 bits – 8 patterns i.e 000, 001, 010, 011, 100, 101, 110, 111

Mathematically: n bits yields 2n patterns.

Bytes: A Byte is just 8 Bits and is the smallest unit of memory that can be addressed in many computer systems.
