Network standards
                              The standards are the precise documents. these documents contain technical and physical specification about the network being designed. By following the network standards, the networks can be reliable and efficient.

Types of Network Standards
There are two types of network standards
1-    De facto standards
2-    De jure standards

De Facto Standards
                               De facto means "by tradition" or "by facto ". these standards were developed without any formal planning.these standards came into existence due to historical developments.these standards are most commonly used by the organizations all over the world. SNA (System Network Architecture) is an example of De Facto standard.

De Jure Standards
                             De Jure means "according to law or regulation". these standards have been properly designed according to the needs of data communication. these standard are approved by international organizations.

Benefits of Networking
The main benefits or uses of computer networking are as follows:

Communication
                            Using a network, different people can communicate with each other all over the world.people can communicate at very low cost via e-mail, chatting, telephone, video telephone, video conferencing,groupware, and SMS service etc.

Data Sharing
                      Data or information can be shared among different users. Any authorized user can access data stored on other computers on the network. for example, on the internet, large number of internet users can access same database.

Sharing Resources
                               In a computer network, resources such as, printers, scanners, plotters, CD-ROM drivers, hard disk and modems can be shared among different users.

Sharing Software
                            In a computer network, usually application programs and other software are stored on the central computers. Users connected to a network can access these programs or software.
Saving Money 
                        An organization can save a lot of money by sharing different devices such as printers, scanners, plotters, and large hard disks over a network. Without a facility of network, these devices have to be arranged separately for each user. It becomes very costly for an organization. Similarly, different software's can be shared over a network instead of purchaing  separate copy of the software for each user.


Data Security and Space
                                        Computer network provides a centralized data storage.Data can easily be managed. similarly, security features can be implemented easily.
