The system of notation that uses base 16 is called hexadecimal, also known as hex. This system uses 16 symbols to represent numbers, compared to the decimal system, which uses 10 symbols. The symbols used in hexadecimal are the numbers 0-9 and the letters A-F, with A representing the decimal value of 10, B representing 11, and so on up to F, which represents 15.
Hexadecimal is often used in computing and networking to represent binary values, which are often too cumbersome to work with in their raw form. Binary values consist of only 0s and 1s, and can quickly become difficult to read and work with when dealing with long strings of numbers.
By converting binary values into hexadecimal, it becomes easier to work with and compare different values. For example, a binary value of 1101 0101 can be represented as D5 in hexadecimal.
In contrast, octal is a system of notation that uses base 8, and binary is a system of notation that uses base 2. CIDR, or Classless Inter-Domain Routing, is a method used for allocating IP addresses and does not involve a system of notation.
