BENEFITS

The many benefits that networking offers to us are:

1.Helps to enhance connectivity.

Networks connect and link unlimited number of computers. This in turn connects the people using those computers. Individuals within a work group are connected through local area networks. Many LANs in far off locations are interconnected through larger wide area networks (WANs). These connections ease out communication between people using technologies like e-mail. Today e-mail has become the easiest, and cheapest mode of transformation of information between the users.

2.Networking helps in sharing of hardware.

Networks help in sharing of different kinds of hardware devices. For example, sharing of a single printer in an office of twenty people is done through networking of wires. This saves lot of cost that could otherwise have incurred if twenty different printers were provided for each computer in use.

3.Eases out management of data.

Networking provides the advantage of centralization of data from all the user systems to one system where it can be managed in an easy and better way. Administrators can thus manage all this data efficiently and in the best interest of the company. Even the access of this data becomes easy for the users.

4.Internet.

The most beautiful gift of networking is internet that is massively used by people all over the world. Whenever you are accessing Internet, you are making use of a network. The benefits of internet need no mentioning. Thanks to the wonderful world of networking.

5.Data sharing.

Sharing of data through the use of networks helps save a lot of time and energy. It also facilitates the use of applications like databases that are based on ability of many individuals to access and to share exactly the same data.

6.Networking has promoted gaming

Many internet games like WOW accounts are being played by players all over the world using common servers. These give fun and enjoyment to people and also improve their skills.

WHAT IS NETWORK CLASSIFICATION.

There are two type of transmission technology: Broadcast networks have a single communication channel that is shared by all the machines on the network. Short messages, called packets in certain contexts, sent by any machine are received by all the other. An address field with the packet specifies for whom it is intended. Upon receiving a packet is intended for itself, it processes the packet; if the packet is intended for some other machine, it is just ignore.
 * broadcast,
 * point-to-point (peer-to-peer).

As an analogy, consider someone standing at the end of a corridor with many rooms off it and shouting.

Although the packet may actually be received (heard) by many people, only Watson responds. The other just ignore it. Another example is an airport announcement asking all flight 444 passengers to report to gate 10.

Broadcast systems generally also allow the possibility of addressing a packet to all destinations by using a special code in the address field. When a packet with his code is transmitted, it is received and processed by every machine on the network. This mode of operation is called broadcasting. Some broadcast system also support transmission to a subset of the machines, something known as multicasting. one possible scheme is to reserve on e bit to indicate multicasting. the remaining n-1 address bits hold a group number. Each machine can "subscribe" to any or all the the groups. When a packet is sent to a certain group, it is delivered to all machines subscribing to that group.

On the other hand, point-to-point (peer-to-peer) networks consist of many connections between individual pairs of machines. To go fro the source to the destination, a packet on this type of network may have to first visit one or more intermediate machines. Often multiple routes, of different lengths are possible, so routing algorithms play an important role in point-to-point networks. As a general rule (although there are many exception), smaller, geographically localized networks tend to use broadcasting, whereas larger networks usually are point-to-point
