A beacon is an intentionally conspicuous device designed to attract attention to a specific location.

Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy.

Beacons help guide navigators to their destinations. Types of navigational beacons include radar reflectors, radio beacons, sonic and visual signals. Visual beacons range from small, single-pile structures to large lighthouses or light stations and can be located on land or on water. Lighted beacons are called lights; unlighted beacons are called daybeacons.

Beaconing is the process that allows a network to self-repair network problems. The stations on the network notify the other stations on the ring when they are not receiving the transmissions. Beaconing is used in Token ring and FDDI networks.

Joe Bonamassa (born May 8, 1977) is an American blues rock guitarist and singer. He began his career playing guitar in the band Bloodline, which featured the offspring of several famous musicians (such as Miles Davis, Robby Krieger and Berry Oakley of The Allman Brothers Band). He released his first solo album A New Day Yesterday in 2000, and has since released nine more solo studio albums, four live albums and three live DVDs, along with two albums with the band Black Country Communion and one album in collaboration with vocalist Beth Hart. He tours the world regularly, and has developed a large following in the U.K. especially. His most recent album, Driving Towards The Daylight, reached #2 on the U.K. Top 40 Albums Chart, and he completed an arena tour there in 2012. In 2009 he was the recipient of the Classic Rock Magazine "Breakthrough Artist of the Year" award, and The Guardian said of him: "the 32-year-old from upstate New York has consolidated a reputation as the pre-eminent blues-rock guitarist of his generation".
