It is true that a PC can work as the network server. It is also true that lot many people turn their old computers in to the home network servers. But it is wrong to say that PC can replace the real server. The needs of the home or the small organizations might be too small and hence they can use the desk top PC as a server. The first point is that a server has to function for 24 hours a day and 7 days a week. For this you need a special device. There are lot many features that you will find only in the network server and not in the desktop PC. The network server will have duel processors. It can have hot swappable components. This means you can change them while the work of the network server is going on simultaneously without any harm.
The other important features that you can find in the network server example will be redundant hard drives and power supplies. The network server will be scalable and it will not only meet the present demands but will meet the future demands also. The network server will process data faster and more efficiently. You can take any network server example and get these parameters confirmed.
We are considering file server as the network server example. The most important work that the network file server does is protecting and keeping the files secure the access to the files is fast. Suppose that one work station fails then you can go to another work station and can access the files easily. In any company there are different levels of managements. You do not want all sorts of people to view all types of files. This is possible in this type of network file server. Each person can have his personal folder to store files at his level. These files will also get all the back up of this network file server system.
There us always increased reliability in this type of network file server. If one power supply fails, then another back up will tart immediately. There will not be loss of data and the productive time. This same thing also applies to the hard drives. If a hard drive gets corrupt, the work does not stop and there is no loss of data also. The hard drives in this network file server are of hot swappable type. This means you do not have to shut the whole network file server to replace the corrupt hard drive. The virus management in the network file server will be of top quality. There is always centralized back up system in this type of network file server. I hope I have explained well the concept of the server with the help of this network sever example.
