Computer Data Storage

• Computers represent information as patterns of bits (0's and 1's), known as base 2; e.g. 1011101000010101000111100011
• People use base 10; doesn't translate well into base 2
• Hexadecimal (base 16) works well with binary; computer programmers often work in base 16
• Group the bits into sets of 4 and translate into hexadecimal using the chart below

• The number above (1011101000010101000111100011) translates into:
