Document Summary

Data vs. information: data: a representation of a fat, a figure, or an idea, information: data that has been organized or presented in a meaningful fashion, e. g. 7135553297, zoe, and richardson are pieces of data alone, but a contact listing, zoe richardson with phone number [phone], becomes information. Computers process (manipulate, calculate, organize) data and information: computers work exclusively with numbers, binary language: a language communicated by computers that is composed of only two binary digits, 0s and 1s, or bits for short, byte: 8 bits. Kilobyte (kb) = 210 bytes: megabyte (mb) = 220 bytes, gigabyte (gb) = 230 bytes. Computers use hardware and software to process data: hardware: any part of the computer that you can physically touch. Tablet computer: a portable computer integrated into a flat multi-touch sensitive screen. Tablet (or convertible) pc: similar to a laptop but the monitor swivels and holds flat; can be a laptop or tablet.
