What is the meaning of Aloha?

The word "Aloha" is a Hawaiian word. As answers.com opened on my computer in a window called "Today's Highlights ...", it gave answers.com's definition of "Aloha" as follows:

"Aloha. The traditional Hawaiian greeting means more than just hello and goodbye. According to ethymologists, the word aloha breaks down into "alo," meaning presence, front or face, and "ha," meaning breath; the literal meaning is often given as "the presence of breath" or "the breath of life." The word represents a spirit of harmony, affection and mutual respect. "Aloha 'Oe," one of Hawaii's most famous songs, was written by the last queen of the Hawaiian Islands, Liliuokalani, who was born on this date (September 02, 2007) in 1838."

ALOHA: ALOHA is a system for coordinating and arbitrating access to a shared communication Networks channel. It was developed in the 1970s by Norman Abramson and his colleagues at the University of Hawaii. The original system used for ground based radio broadcasting, but the system has been implemented in satellite communication systems.

A shared communication system like ALOHA requires a method of handling collisions that occur when two or more systems attempt to transmit on the channel at the same time. In the ALOHA system, a node transmits whenever data is available to send. If another node transmits at the same time, a collision occurs, and the frames that were transmitted are lost. However, a node can listen to broadcasts on the medium, even its own, and determine whether the frames were transmitted.

Aloha means "Hello". Aloha is a multiple access protocol at the datalink layer and proposes how multiple terminals access the medium without interference or collision. In 1972 Roberts developed a protocol that would increase the capacity of aloha two fold. The Slotted Aloha protocol involves dividing the time interval into discrete slots and each slot interval corresponds to the time period of one frame. This method requires synchronization between the sending nodes to prevent collisions.

There are two different versior.s/types of ALOHA:

(i) Pure ALOHA

(ii) Slottecl ALOHA
