Davidson, Shelby J. (born: 1868 - died: 1931) Born in Lexington, Davidson became a lawyer. He invented a paper rewinding device for a tabulating machine and an adding machine attachment for automatically adding in set amounts. Shelby Davidson's Papers are at Howard University.

Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters.
How do I properly convert bytes to kilobytes, megabytes, and gigabytes? There can be some confusion as to how many bytes a kilobyte actually represents. When referring to memory a kilobyte is not 1,000 bytes, but rather 1024 bytes (which is 2^10 bytes). This is because memory must increase in binary (or base two) increments. So to convert from bytes to kilobytes you would divide the number of bytes by 1024. See the table below for other prefixes.
