Document Summary

Information technology the study or use of systems (especially computers and telecommunications) for storing, retrieving, and sending information. Computers: receive, read, and process, computers need input, output, process, store things, program, charles babbage came up with a computer to help balance tables, ex. Navy at sea firing cannons on boats: first programmer = aida lovelust, first computer because we could program it, wwii, vacuum tubes = electronic computers, 1980s pcs came out. User interface (ui) the way a user interacts with system and how this responds to such interaction. For example, colors, contrast, buttons interaction, feedback, touch feedback, hover-on feedback, etc: to see if program is working correctly, terrible ui leads to an even worse ux. Feedback: cursor is replaced by a different icon, some apps give custom feedback, or use a progress bar to give an estimate on time remaining. In the 70s the first personal computer (the alto) was developed by xerox.
