Numeral system - is:

• sign system, where numbers are written according to certain rules with the help of characters (numbers) of an alphabet

• arbitrary sequence of digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

• infinite sequence of digits 0 and 1

• set of numbers I, V, X, L, C, D, M

• the set of natural numbers and arithmetic signs

Binary system use 0 and 1 digits, which used in the computer, because of:

• In its most simple multiplication table

• In addition it is the simplest

• It does not carry over units in the senior ranks at addition

• Elements of a computer may be only in two stable states

• Computer operates on DC
