  ALOHAnet - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-05)
It was first deployed in 1970, and while the network itself is no longer used, one of the core concepts in the network is the basis for the almost-universal Ethernet.
One of the early computer networking designs, the ALOHA network was created at the University of Hawaii in 1970 under the leadership of Norman Abramson.
The network was a star, with a single central computer (a HP 2100) at the university receiving all messages on the random access channel, and then re-broadcasting them to all of the nodes on the broadcast frequency.

 Hawaii Aloha Network - Network FAQ'S
Intra-nets, networks that run within a business location and connect its offices and departments, are a critical business asset for research, sales, accounting and administrative activities.
You might think that you’d like to have the economy of networking under Windows 95 or 98, but the core business application you want to use might be designed for the business Windows NT 40, windows 2000 or XP operating systems or some version of Unix.
The ideal combination for a line-of-business network is a switch with an adequate number of 10Mbps ports for your client PCs and with some 100 Mbps ports for the file and application servers.

The earliest idea of a computer network intended to allow general communication between users of various computers was the ARPANET, the world's first packet switching network, which first went online in 1969.
The need for an internetwork appeared with ARPA's sponsorship, by Robert Kahn, of the development of a number of innovative networking technologies; in particular, the first packet radio networks (inspired by the ALOHA network), and a satellite packet communication program.
Connecting these disparate networking technologies was not possible with the kind of protocols used on the ARPANET, which depended on the exact nature of the subnetwork.

 History of the Internet   (Site not responding. Last check: 2007-10-05)
The Internet's roots lie within the ARPANET, which not only was the intellectual forerunner of the Internet, but was also initially the core network in the collection of networks in the Internet, as well as an important tool in developing the Internet (being used for communication between the groups working on internetworking research).
At the end of the 1980s, the US Department of Defense decided the network was developed enough for its initial purposes, and decided to stop further funding of the core Internet backbone.
An additional network protocol, a hypertext transfer protocol (HTTP), was also invented for reduced overhead in transfers, but the true genius of the new system was that a new protocol was useful but not necessary; the URL and HTML system was backwards compatible with existing protocols like FTP and Gopher.

The ALOHA Circle (or local reliable APRS network size) 13 Jan 2003 --------------------------------------------------------------------- WB4APR There are three things that are very important to the network and user education and which some software does does *not* show to the user to help him be a good steward of the shared channel.
THE ALOHA CIRCLE: ----------------- Many users these days have no appreciation of the limits of the 144.39 or other national APRS network even though it is trivial to calculate and display since it is just the definition of a 100% full channel based on the TX rates of surrounding stations.
I have called on all software to permanently display the calculated ALOHA circle for *own-station* and always display it on the users map so that the user is always aware of his effective range and SHOULD NOT send his packets beyond that 100% saturated channel range...

 Distinguished Lecture
Although some networks are based upon a peer-to-peer RF architecture, most networks are based upon a client-server architecture in order to obtain significant RF link advantages in both directions and in order to better match the logic of most user applications.
Conventional first generation ALOHA channels and their derivatives are all based upon a connection free, asymmetric client-server architecture, but in the wireless context they are condemned to narrowband operation for the same transmit power reasons which restrict TDMA architectures.
