 What is a Bit in Computing?


A bit (binary digit) is the smallest unit of data that a computer can process and store.

A bit is always in one of two physical states, similar to an on/off light switch.

The state is represented by a single binary value, usually a 0 or 1. 

However, the state might also be represented by yes/no, on/off or true/false.

What is Bubble Sort?

 

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. This algorithm is named because smaller elements "bubble" to the top of the list with each iteration. However, it is not very efficient, especially for large lists, due to its quadratic time complexity. Despite its inefficiency, it is often used in educational contexts to demonstrate sorting algorithms due to its simplicity.
