Binary (base-2) uses digits 0 and 1 for Tech+
Short answer
Binary (base-2) uses digits 0 and 1. Modern computing uses different notational systems (numeral systems) to represent values. The decimal system (base-10) is the standard for everyday counting, using ten digits 0 through 9. Computers operate using binary (base-2), which only uses the digits 0 and 1 and is the foundation of all digital data. For convenience, binary data is often represented in hexadecimal (base-16) or octal (base-8) format, since one hexadecimal digit represents four binary bits and one octal digit represents three bits.

Concept 1
Binary (base-2) uses digits 0 and 1
Binary (base-2) uses digits 0 and 1. Modern computing uses different notational systems (numeral systems) to represent values. The decimal system (base-10) is the standard for everyday counting, using ten digits 0 through 9. Computers operate using binary (base-2), which only uses the digits 0 and 1 and is the foundation of all digital data. For convenience, binary data is often represented in hexadecimal (base-16) or octal (base-8) format, since one hexadecimal digit represents four binary bits and one octal digit represents three bits. In summary: - Binary: Base-2 system using 0 and 1; fundamental for computer operations (all machine code is binary). - Octal: Base-8 system using 0-7; historically used in computing (e.g.
