Word or Term Description or Explanation
X-Modem a file transfer protocol originated by Ward Christensen (might not have his name spelled correctly) in the days of CP/M for modem tranfer of files - it was a Public Domain protocol - it consists of 128-byte blocks with a simple checksum byte and an ACK/NAK handshake - in the days of 300-baud modems, this was quite impressive! - and, since each block is a fixed length, binary data can be sent without converting it to a readable ASCII format
XGA Extended Graphics Adapter or Array - The definition varies (as well as the name) depending which book you read but it is roughly 1024 × 768 in lots of colours!
XTV the result of a collaboration between Pace and NDS, XTV is an integrated digital set-top box that includes a large amount of local storage - the smart software within XTV selects and stores programmes that the viewer is likely to want to watch, by interpreting meta-data inserted by the broadcaster at the head-end and comparing it with viewer preferences - in addition, XTV enables personalised playout so that the menu of both live and the stored content are in the order most likely to match the viewer's taste and habits
