**What is BNS full form in computer?**

The BNS full form in computer is **Binary Number System.** The binary number system is a key idea in computing and digital technologies. It is a base-2 numbering system with only two symbols, namely 0 and 1. These two symbols, known as bits, represent the two conceivable states of a digital signal: off (0) and on (1). Unlike the decimal system, which has 10 digits binary has only two, making it suitable for the binary nature of computers.

**Importance of binary system in computers:**

A computer conducts all processes in binary, including arithmetic, logical comparisons, and data storage. The binary number system is vital for computers because it perfectly matches the way hardware works. Digital circuits, the building blocks of computer technology, are made up of transistors that can be either on or off. These two states correspond to the binary numbers 1 and 0, allowing computers to efficiently store and analyze data in binary.

**The use of binary system in data representation:**

In addition to numbers, binary is used to represent other forms of data in computers. For example, text is encoded in binary using standards such as ASCII or Unicode, with each character allocated a unique binary code. In ASCII, the letter ‘A’ is represented by the binary number 01000001, ‘B’ by 01000010, and so on. Images and music are also split down into binary sequences that represent various colors, brightness levels, and sound frequencies.
