Document Summary
Graphics & media: scalable outline & bit-mapped fonts binary number representation & text pixels, colors and resolution, sound & digital audio, film & digital video, data compression, vector graphics. Adobe invented postscript, a technology used by laser printers and gui for printing or displaying outline fonts. Thanks to scalable outline fonts, texts on our displays and printers are looking much better. Binary number representation: inside a computer, all data are represented in binary, including numbers, a binary digit (or a bit) consists of two values: 0 and 1: any number can be represented in binary. Property of a byte: a byte consists of 8 binary digits, or 8 bits, with a byte, we can represent. 28 =2x2x2x2x2x2x2x2=256numbers: with 2 bytes (16 bits), we can represent 256 x 256 = 65,536 numbers; with 4 bytes (32 bits), Storage sizes: 1kb (kilo-byte) = 1,024 bytes (note: kb means.
