Binary System Computers are not as smart as humans, it's easy to make an electronic machine with two states: on and off, or 1 and 0. Computers use binary system, binary system uses 2 digits: 0, 1 And thus the base is 2.
Binary System Each digit in a binary number is called a BIT, 4 bits form a NIBBLE, 8 bits form a BYTE, two bytes form a WORD, two words form a DOUBLE WORD.
Binary System There is a convention to add "b" in the end of a binary number, this way we can determine that 101b is a binary number with decimal value of 5.
SUB in Binary System ADD in Binary System 0-0=0 1-0=1 0+0=0 1+0=1 0+1=1 0-1=1 borrow 1 1-1= 0 1+1= 0 carry 1 EX: 1011b -1010b=0001b EX: 1011b +1010b 1011b+1111b 1100b-1011b=0001b
