1. File Sharing: The major advantage of a computer network is that is allows file sharing and remote file access. A person sitting at one workstation of a network can easily see the files present on the other workstation, provided he is authorized to do so. It saves the time which is wasted in copying a file from one system to another, by using a storage device. In addition to that, many people can access or update the information stored in a database, making it up-to-date and accurate.
2. Resource Sharing: Resource sharing is also an important benefit of a computer network. For example, if there are four people in a family, each having their own computer, they will require four modems (for the Internet connection) and four printers, if they want to use the resources at the same time. A computer network, on the other hand, provides a cheaper alternative by the provision of resource sharing. In this way, all the four computers can be interconnected, using a network, and just one modem and printer can efficiently provide the services to all four members. The facility of shared folders can also be availed by family members.
3. Increased Storage Capacity: As there is more than one computer on a network which can easily share files, the issue of storage capacity gets resolved to a great extent. A standalone computer might fall short of storage memory, but when many computers are on a network, memory of different computers can be used in such case. One can also design a storage server on the network in order to have a huge storage capacity.
4. Increased Cost Efficiency:There are many software available in the market which are costly and take time for installation. Computer networks resolve this issue as the software can be stored or installed on a system or a server and can be used by the different workstations.
5. Communication
Communication is one of the biggest advantages provided by the computer networks. Different computer networking technology has improved the way of communications people from the same or different organization can communicate in the matter of minutes for collaborating the work activities. In offices and organizations computer networks are serving as the backbone of the daily communication from top to bottom level of organization. Different types of softwares can be installed which are useful for transmitting messages and emails at fast speed.
6. Instant and multiple accesses
Computer networks are multiply processed .many of users can access the same information at the same time. Immediate commands such as printing commands can be made with the help of computer networks.
7. Video conferencing
Before the arrival of the computer networks there was no concept for the video conferencing. LAN and WN have made it possible for the organizations and business sectors to call the live video conferencing for important discussions and meetings
.
8. Internet Service
Computer networks provide internet service over the entire network. Every single computer attached to the network can experience the high speed internet. Fast processing and work load distribution
9. Broad casting
With the help of computer networks news and important messages can be broadcasted just in the matter of seconds who saves a lot of time and effort of the work.
People, can exchange messages immediately over the network any time or we can say 24 hour.
10. Photographs and large files
Computer network can also be used for sending large data file such as high resolution photographs over the computer network to more then when users at a time.
11. Remote access and login
Employees of different or same organization connected by the networks can access the networks by simply entering the network remote IP or web remote IP. In this the communication gap which was present before the computer networks no more exist.
12. Flexible
Computer networks are quite flexible all of its topologies and networking strategies supports addition for extra components and terminals to the network. They are equally fit for large as well as small organizations.
13. Reliable
Computer networks are reliable when safety of the data is concerned. If one of the attached system collapse same data can be gathered form another system attached to the same network.
14. Data transmission
Data is transferred at the fast speed even in the scenarios when one or two terminals machine fails to work properly. Data transmission in seldom affected in the computer networks. Almost complete communication can be achieved in critical scenarios too.
15. Provides broader view
For a common man computer networks are an n idea to share their individual views to the other world.
