The nice feature with Two’s Complement is that addition and subtraction of Two’s complement numbers works without having to separate the sign bits (the sign of the operands and results is effectively built-into the addition/subtraction calculation). Remember: −2n−1 ≤ Two’s… Read More »
Many different coding systems are used to represent data today. What is the importance of coding systems? To represent numeric, alphabetic, and special characters in a computer’s internal storage and on magnetic media, we must use some sort of coding system. In computers, the code is made up of fixed size groups of binary positions.… Read More »

Although we type words and letters in the computer, the computer does not understand the words and letters. Rather, those words and letters are translated into numbers. Computers “talk”… Read More »
