Hexadecimal
The hexadecimal system, or base-16, is a numeral system that uses sixteen symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C,
D, E, and F. It is commonly used in computing and digital electronics because it provides a more compact way to represent
binary data. Each hexadecimal digit corresponds to four binary digits (bits). For example, the binary number 10101111
can be written as AF in hexadecimal. Hexadecimal is frequently used in programming for memory addresses,
color codes in web design (e.g., #FF5733), and representing machine-level instructions in a readable format.
Text
Text refers to sequences of characters that convey readable information to humans. In computing, text is represented using encoding systems like ASCII or Unicode, which map each character to a numeric value. Text data is widely used in applications ranging from simple documents and communication to complex programming and data processing. The flexibility of text as a medium for communication makes it a fundamental part of human-computer interaction. Modern systems often rely on Unicode because it supports a vast range of characters from different languages and symbols, enabling global communication.
