Advantages of computer networking?
The Advantages (Benefits) of Networking
You have undoubtedly heard the "the whole is greater than the sum of its parts". This phrase describes networking very well, and explains why it has become so popular. A network isn't just a bunch of computers with wires running between them. Properly implemented, a network is a system that provides its users with unique capabilities, above and beyond what the individual machines and their software applications can provide.
Most of the benefits of networking can be divided into two generic categories: connectivity and sharing. Networks allow computers, and hence their users, to be connected together. They also allow for the easy sharing of information and resources, and cooperation between the devices in other ways. Since modern business depends so much on the intelligent flow and management of information, this tells you a lot about why networking is so valuable.
Here, in no particular order, are some of the specific advantages generally associated with networking:
True networking allows thousands of employees to share data much more easily and quickly than this. More so, it makes possible applications that rely on the ability of many people to access and share the same data, such as databases, group software development, and much more. Intranets and extranets can be used to distribute corporate information between sites and to business partners.
Entertainment: Networks facilitate many types of games and entertainment. The Internet itself offers many sources of entertainment, of course. In addition, many multi-player games exist that operate over a local area network. Many home networks are set up for this reason, and gaming across wide area networks (including the Internet) has also become quite popular. Of course, if you are running a business and have easily-amused employees, you might insist that this is really a disadvantage of networking and
3. Unlike Ethernet, Token Ring uses a ring topology whereby the data is sent from
one machine to the next and so on around the ring until it ends up back where it
started. It also uses a token passing protocol which means that a machine can
only use the network when it has control of the Token, this ensures that there are
no collisions because only one machine can use the network at any given time.

Virtual meetings on Internet are called?
Perhaps it’s easiest to explain what virtual meetings are by explaining what they are not. Virtual meetings are not video conferencing. Video conferencing technology uses cameras and satellites to transmit images of the participants during a meeting. Virtual meetings are not chat rooms. Chat rooms provide a real-time Internet-based system to exchange text messages. Virtual meetings combine good old-fashioned teleconferencing (over the telephone) with Internet document viewing and editing. Virtual meetings are real-time, interactive, and a valuable way to share information quickly, easily and cost effectively. Somewhere it is also termed as "webinar".
