bit - Answer-a bit is the single unit of information in a computer, typically represented as a 0 or 1. We
will call each element of a binary message a bit. "Bit" is short for binary digit. So for example if you have
a binary message A B B A, we would say that is a 4-bit message
Bit rate (or bitrate) - Answer-The number of bits that are conveyed or processed per unit of time. e.g. 8
bits/sec
Protocol - Answer-A set of rules governing the exchange or transmission of data between devices. For
our purposes today a "protocol" is the set of rules that send, receive, and interpret the binary messages
Permutation - Answer-an ordered arrangement of objects
Number System - Answer-a collection of symbols and the rules for ordering them
computer information needs to be ____________ - Answer-binary encoded
all _____________________ solve the problem of how to send this information from one place to
another - Answer-communication protocols
ASCII - Answer-American Standard Code for information interchange. ASCII is the universally recognized
raw text format that only computer can understand (Ask-ee) 7 bits long
Code - Answer-(v) to write code, or to write instructions for a computer
bandwidth - Answer-bit-rate of available or consumed information capacity expressed typically in metric
multiples of bits per second.
