IEEE 802.2 is the original name of the ISO/IEC 8802-2 standard which defines Logical Link Control (LLC) as the upper portion of the data link layer of the OSI Model. The original standard developed by the Institute of Electrical and Electronics Engineers (IEEE) in collaboration with the American National Standards Institute (ANSI) was adopted by the International Organization for Standardization (ISO) in 1998, but it still remains an integral part of the family of IEEE 802 standards for local and metropolitan networks.
LLC is a software component that provides a uniform interface to the user of the data link service, usually the network layer. LLC may offer three types of services:
Conversely, the LLC uses the services of the Media Access Control (MAC), which is dependent on the specific transmission medium (Ethernet, Token Ring, FDDI, 802.11, etc.). Using LLC is compulsory for all IEEE 802 networks with the exception of Ethernet. It is also used in Fiber Distributed Data Interface (FDDI) which is not part of the IEEE 802 family.
Design was a British vocal group of the early 1970s and its members were Barry Alexander, Gabrielle Field, Kathy Manuell, Jeff Matthews, John Mulcahy-Morgan and Geoff Ramseyer. Their musical style has been described as folk rock 'with intricate and appealing harmonies and an interesting psychedelic twist' and 'sunshine harmony pop with a light hippy vibe' and is now called sunshine pop. Design released 13 singles and 5 albums in the UK and appeared on more than 50 television shows before they split up in 1976.
Barry Alexander, Jeff Matthews and Geoff Ramseyer all played guitar in addition to singing, while Barry also played keyboards. Gabrielle Field occasionally played tenor recorder.
Design was formed as a six-piece vocal group by singer and songwriter Tony Smith while he was working at the BBC in London in December 1968. The group signed a recording contract with Adrian Kerridge at Lansdowne Studios and recorded their first album Design during 1969. This led to a two-album deal with Epic Records in the USA.
A rugby league football team consists of thirteen players on the field, with four substitutes on the bench. Players are divided into two general categories, forwards and backs.
Forwards are generally chosen for their size and strength. They are expected to run with the ball, to attack, and to make tackles. Forwards are required to improve the team's field position thus creating space and time for the backs. Backs are usually smaller and faster, though a big, fast player can be of advantage in the backs. Their roles require speed and ball-playing skills, rather than just strength, to take advantage of the field position gained by the forwards.
The laws of the game recognise standardised numbering of positions. The starting side normally wear the numbers corresponding to their positions, only changing in the case of substitutions and position shifts during the game. In some competitions, such as Super League, players receive a squad number to use all season, no matter what positions they play in.
The center (C), also known as the five or the big man, is one of the five positions in a regulation basketball game. The center is normally the tallest player on the team, and often has a great deal of strength and body mass as well.
The tallest player to ever be drafted in the NBA or the WNBA was the 7'8" (2.33 m) Yasutaka Okayama from Japan, though he never played in the NBA. The tallest players to ever play in the NBA, at 7'7" (2.31 m), are centers Gheorghe Mureșan, and Manute Bol. Standing at 7'2" (2.18 m), Margo Dydek is the tallest player to have ever played in the WNBA.
The center is considered a necessary component for a successful team, especially in professional leagues such as the NBA. Great centers have been the foundation for most of the dynasties in both the NBA and NCAA. The 6’10" (2.08 m) George Mikan pioneered the Center position, shattering the widely held perception that tall players could not develop the agility and coordination to play basketball well, and ushering in the role of the dominant big man. He led DePaul University to the NIT title, then, after turning professional, won seven National Basketball League, Basketball Association of America and NBA Championships in his ten-year career (1946–56), nine of them with the Minneapolis Lakers. Using his height to dominate opposing players, Mikan invented the hook shot and the shot block; as a consequence, the NCAA, and later NBA, adopted the goaltending rule, and, in 1951, the NBA widened the foul lane, a decision known as the 'Mikan rule'.
Forwards are the players on an association football team who play nearest to the opposing team's goal, and are therefore most responsible for scoring goals.
Their advanced position and limited defensive responsibilities mean forwards normally score more goals on behalf of their team than other players.
Modern team formations generally include one to three forwards; for example, the common 4–2–3–1 formation includes one forward. Unconventional formations may include more than three forwards, or none.
The centre-forward is often a tall player, typically known as a target man, whose main function is to score the majority of goals on behalf of the team. The player may also be used to win long balls or receive passes and retain possession of the ball as team-mates advance, to help teammates score by providing a pass ('through ball' into the box); the latter variation usually requiring quicker pace. Most modern centre-forwards operate in front of the second strikers or central attacking midfielders, and do the majority of the ball handling outside the box. The present role of centre-forward is sometimes interchangeable with that of an attacking midfielder, especially in the 4–3–1–2 or 4–1–2–1–2 formations. A centre-forward usually must be strong, to win key headers and 'outmuscle' defenders. The term centre-forward is taken from the early football playing formation in which there were five forward players: two outside forwards, two inside forwards, and one centre-forward.
