Any message written over a fixed set of symbols can be represented as a binary string (a sequence of 0's and 1's) Binary digits 0 and 1 are called bits To reduce computation overhead, encryption algorithms should only use operations that are easy to implement For a binary string X: The length of X, denoted by |X|, is the number of bits in X If |X| = l, X is an l-bit binary string Let a be a binary bit and k a non-negative integer. Denote by ak a binary string consisting of k copies of a Denote the concatenation of X and Y by XY or...

Computer processing is performed by transistors, which are switches with only two possible states: on and off. All computer data is converted to a series of binary numbers– 1 and 0. For example, you see a sentence as a collection of letters, but the computer sees each letter as a collection of 1s and 0s.

A bit (binary digit) is the smallest unit of information • N = 2n where N is the number of representations and n is the number of bits (ex. ASCII, Unicode, PCM code etc.) • Data communications transfer information using codes that are transmitted as signals (either analog or digital) • In general, analog lines provide a slow service that contains high error rates.

The Binary System Computing devices communicate with 1s and 0s A groups of 8 bits = 1 byte Binary numbers are based on the powers of 2 because there are only 2 symbols: 0 and 1 Binary can be converted to decimal in a similar way that decimal numbers are figured ATHENA The Binary System (2) Binary can be converted to decimal in a similar way that decimal numbers are figured Example: 1010 = (1x23)+(0x22)+(1x21)+(0x20) = (1x8)+(0x4)+(1x2)+(0x1) = 8 + 0 + 2 + 0 1010 = 10

In this module we are going to cover various aspects of IP. We are going to start by looking at one of the most common protocol stacks: The OSI protocol stack and look at how communications is broken down into seven core areas. We are then going to compare the seven layer OSI stack with the TCP/IP protocol stack. Then, we are going to cover numbering systems and see how to translate between decimal and binary.

Our PC's are data processors. PC's function is simple: to process data, and the processing is done electronically inside the CPU and between the other components. That sounds simple, but what are data, and how are they processed electronically in a PC? That is the subject of these pages.
