i) Convert 01101001 from binary to denary. ii) Convert 27 from denary to hexadecimal. ii) State one use of hexadecimal in computing and why it is more beneficial in this application that binary.

i) 011010012 = 10510ii) 2710 = 1B16iii) Colour codes, MAC addresses, memory locations, many others.The main advantage of hexadecimal over a number system like binary is that it is far more compact. A 100 bit binary number would only be 25 hexadecimal digits. The benefit of this is it takes up less space on the screen to display a number, and it's also quicker for both a human and the computer to read and write. It is also easy to convert from hexadecimal to binary and vice versa for a computer.
