CP102 Lecture Notes - Lecture 2: Cable Modem, Embedded System, Grid Computing
Document Summary
Data us a representation of a fact, figure, or idea: data can be a number, word, picture, or recording, information is data that is organized and presented in meaningful fashion. Computers are good at processing data into information: binary language consists of 0 and 1, each 0 and 1 is a binary digit, eight of these binary digits to create one byte. Distributed or grid computing are computing devices working together: creates cheap supercomputers theskynet allows your device to process astronomical data while the cpu is on idle. Combine keystrokes to take shortcuts within an application. Near field communication can communicate with each other when they are held near. An output device lets processed data out of your computer in a form of a text, pictures, sounds, or video. Augmented reality is a type of computer generated sensory input: includes video, graphics, and gps. Pixels are monitor screen with grids made up of millions of tiny dots.
