0x1021

0x1021 is a hexadecimal number. In decimal representation, it is equal to 4129. The prefix "0x" indicates that the number is expressed in base 16. Hexadecimal is a base-16 numbering system that uses sixteen distinct symbols, typically 0-9 and A-F, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.

The number 0x1021 can be broken down as follows in base 10: (1 * 16^3) + (0 * 16^2) + (2 * 16^1) + (1 * 16^0). This calculation results in (1 * 4096) + (0 * 256) + (2 * 16) + (1 * 1), which equals 4096 + 0 + 32 + 1, ultimately summing to 4129.

Hexadecimal notation is commonly used in computer science and digital electronics. It is often employed to represent memory addresses, character encodings, and data values in a more compact and human-readable format than binary. For instance, a byte, which is 8 bits, can be represented by two hexadecimal digits. Therefore, 0x1021 represents a specific numerical value that might appear in various computational contexts.
