Introduction

Bit strings are sequences of binary digits (bits) used in computing. They can be used to represent numbers, store data, and to manipulate data. Bit strings are often used to represent data because each bit can be easily manipulated. For example, a bit string can be used to represent the number 5, or it can be used to represent a particular character on a computer display.

Bit strings can also be used to store data, such as text, images, and audio. When data is stored in bit strings, it is often compressed to reduce the size of the file. Additionally, bit strings can be used to manipulate data. For example, they can be used to sort data, find patterns in data, or search for specific data within a larger dataset.
