The number system which uses only the symbols 1 and 0 is called the binary number system.

In the binary number system, also known as the base-2 system, each digit or bit can only have one of two possible values, either 1 or 0. This system is widely used in digital technology and computer science, as it forms the foundation of all modern computing systems.

Binary digits, or bits, are used to represent information in the form of electrical signals within a computer. A single binary digit is also referred to as a "bit," while a group of four bits is called a "nibble," and a group of eight bits is known as a "byte."

The binary number system works on the principle of place value, similar to the decimal system we commonly use, but with a base of 2 instead of 10. Each digit in a binary number represents a power of 2, starting from the rightmost digit.

Converting decimal numbers to binary involves dividing the decimal number by 2 and noting the remainder. The process is repeated until the quotient becomes zero. The binary number is then obtained by arranging the remainders in reverse order.

Binary numbers are particularly important in computer programming, as they are used to represent instructions and data within a computer's memory. Additionally, binary logic forms the basis of how computers perform calculations and process information.

Understanding the binary number system is crucial for anyone working in the field of computer science or digital technology. It allows programmers to manipulate and control data effectively, enabling the development of complex software applications and systems.

In conclusion, the binary number system is a fundamental concept in computer science, utilizing only the symbols 1 and 0 to represent information. Its simplicity and efficiency make it ideal for digital technology applications, playing a vital role in modern computing systems.
