INTERNET CONTROL

ICANN

ICANN was established to regulate human friendly internet domain names. It stands for Internet Corporation for Assigned Names and Numbers. ICANN is a non-profit organization formed to manage and assign domain names and IP addresses. It works closely with the United States government with boards consisting of members from all continents to ensure internationalized goals.
It has been argued that since this company is controlled by the US, the US is gaining too much information and perhaps an international corporation would be a better solution.

W3C

W3C is a group of various companies whose interests are in creating standards and recommendations to improve internet quality. They also engage in education and outreach, developing software and serving as an open forum for discussion about the Web.

The W3C had 144 members as of March 2007

HARDWARE: Topologies

bus

All nodes are connected to a single wire or cable (the bus) which has two endpoints. Each communications device on the network transmits electronic messages to other devices. If some of those messages collide, the sending device will wait and then try to transmit again. The advantage of bus network is that it is can be organized as a peer-to-peer network or client/server network.
It is also relatively inexpensive to install.
The disadvantage is that if the bus network fails, the whole system network fails.
The wider the bus the better!

ring

The ring network is a network in which all communications devices and microprocessors are connected in a continuous loop. Electronic messages pass around the ring until they reach the correct destination; there is no central server.
The advantage of a ring network is that messages only flow in one direction.
The disadvantage is that if a single connection is broken, the whole network stops working. The distributed star or tree topology can provide many of the advantages of the bus and the star topologies. It connects workstations to a central point, called a hub. This hub can support several workstations or hubs which, in turn, can support other workstations. Distributed star topologies can be easily adapted to the physical arrangement of the facility site.

star

A network that links all microcomputer and other communication devices through a central server.
The advantages of this hub is that it prevents impact between messages. The network forms a star shape having the central server in the middle with a single branch outward, the branch will not branch to another device.
Other Advantages Include:
* Good performance.
* Scalable, Easy to set up and to expand.
* Any non-centralised failure will have very little effect on the network, whereas on a ring network it would all fail with one fault.
* Easy to detect faults
* Data Packets are sent quickly as they do not have to travel through any unnecessary nodes.
* It is used for centralised control.
