In computer networking, Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1,000,000,000 bits per second), as defined by the IEEE 802.3-2008 standard. It came into use beginning in 1999, gradually supplanting Fast Ethernet in wired local networks, where it performed considerably faster. The cables and equipment are very similar to previous standards and have been very common and economical since 2010.

The Most Excellent Order of the British Empire is the "order of chivalry of British constitutional monarchy", rewarding contributions to the arts and sciences, work with charitable and welfare organisations and public service outside the Civil Service. It was established on 4 June 1917 by King George V, and comprises five classes, in civil and military divisions, the most senior two of which make the recipient either a knight if male, or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order.
