How are data being represented in computers? Computers work with a binary number system that consists of only two digits - zero and one. Inside the computer binary number is represented by an electrical pulse. One means a pulse of electricity and zero means no pulse. All the data entered into computers is first converted into the binary number system. One digit in binary number system is called bit and combination of eight bits is called byte. A byte is the basic unit that is used to represent the

In the way we count time we go to 60 but in other ways we go to 100. 50 is halfway between 5 and 6 if we measure length‚ weight‚ money‚ or anything else but time. In time halfway between 5 and 6 is 30. Also‚ when you learn to count you go from 0 to 9‚ it is very systematic and once you learn it you never forget. Time is different because the base number is 60.In the way we count time we go to 60 but in other ways we go to 100. 50 is halfway between 5 and 6 if we measure length‚ weight‚ money‚ or
