What is the binary number 1011111 in denary form?
(a)
People use the (a) (or decimal) number system in their day-to-day lives. This system has 10 digits that we can use: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
Binary is a number system that only uses two digits: 1 and 0. All information that is processed by a computer is in the form of a sequence of 1s and 0s. Therefore, all data that we want a computer to process needs to be (a) into binary.
binary numbers are usually written in blocks of four, separated by a space (eg 0111 1011). In denary, numbers are often written in blocks of three (eg 6 428 721).
