Document Summary

Integer any natural or negative number (whole numbers; no decimals) 3. 1 data and computers: data basic values or facts, computers are now multimedia devices. Lossless compression a data compression technique in which there is no loss of information. But a digital signal has only a high or low state, corresponding to the two binary digits: all electronic signals (both analog and digital) degrade as they move down a line. 4 bits represents 16 things, 5 bits 32: 2 bits represent 4 things ex. We don"t consider negative 0, only positive 0. Ex. 0 to 49 are positive, 50 to 99 are negative (-50 to -1: to add, simply add numbers and discard any carry. See cse_b_numericdata: ten"s complement is represented by: The decimal point is now called a radix point, since we are not using decimal system. Numbers to the right of radix point are 2-1, 2-2 etc.
