Loop – instructs the computer to repeat one or more instructions until a certain condition is met ( Examples: DO UNTIL and DO WHILE 162. Component – prewritten code, saves programmers time 163. Desk Checking – reading through a program to make sure it is logical and free of errors 164. Debugger Software – software used to help identify and solve programming problems 165. Alpha Test – includes both Desk Checking AND Debugging 166. Beta Testing – checking a program by running it with real world data 167. LISP – program language used primarily for creating artificial intelligence programs 168. JavaScript – is widely supported by web browsers and adds interactive functions to HTML pages 169. Prototype – limited working system, developed to test design 170. Parallel Implementation – old and new systems are operating side by side until the new system is proven reliable 171. Phased implementation – parts of the new system are implemented separately 172. Virtual Reality – computer generated reality – used in arcade games (example: flight simulators) 173. Charles Babbage – first to define concepts used in the modern computer (memory, programmable processor, output device, etc.) He called “Difference Engine in 1834” 174. Punch cards –used for early computers stored data for calculations and programs 175. Vacuum Tubes – 1 st generation computers used these to store individual bits of data 176. Transistors – 2 nd generation computers used these instead of vacuum tubes, smaller, cheaper and more reliable, also the beginning use of Operating Systems (2 nd generation) 177. Circuits – 3 rd generation – circuits were able to do the work of thousands of transistors or vacuum tubes on a single miniature chip 178. 4 th Generation computers – were microprocessor based, and much smaller, faster and cheaper than 3 rd generation computers. The first microprocessor was developed in 1971. 179. ENIAC – the first programmable electronic computer in the United States completed in 1945 and was designed to calculate trajectory tables for the US Army 180. UNIVAC – first commercially successful digital computer built in 1951, smaller and more powerful than ENIAC
