Why computers use hexal number system?

Computers use the hexadecimal number system because it simplifies binary representation, making it easier for humans to read and understand. Each hexadecimal digit corresponds to four binary digits (bits), allowing for a more compact representation of binary data. This is particularly useful in programming and debugging, as it reduces the complexity of handling long binary strings. Additionally, hexadecimal aligns well with computer architecture, which often operates on byte-sized data (8 bits).
