In today's computers, 8-bit ASCII is used very widely, and since most computer manufacturers treat the 8-bit byte as the smallest addressable unit of memory, bytes and codewords are virtually synonymous. The measure of a piece of text in characters and bytes will be the same. For example, a standard page usually has around 80 characters per line (including blanks which are valid characters), and there are usually 66 lines per page. This gives 80×66 = 5280 characters per page. Since each character requires one byte, this would be 5280 bytes, or about 5.2 Kilobytes. (Remember that a kilobyte is 1024 bytes, so 5280÷1024 gives 5.15625, which, rounded, is about 5.2K.) |
