For an effecient and effective networking the following criteria is most important.
Performance:
The performance depends on many factor some are discussed below:
Number of Users:
A large number of users on a network can slow its reponse time if it is designed for heavy traffic loads. In peak times on a certain network can slow its performance.
Transmission Medium:
The transmission medium used for the network also a main factor for its performance. As data has to travel on it. It can be fibre optics for a faster transfer of data.
Hardware:
The hardware used in networking affect the speed and capacity of transmission. A high computer with big storage will perform better.
Software:
The software used for running applications and data processig at sender reciever end and intermediary nodes also effects the performance of the network.
Reliability:
Rliability of a network on the followings;
Frequency of Failure:
All networks fail occasionally. But a network that fails often have little value to a user.
Recovery Time:
The time taken to restore itself after the failure is recovery time. The network quickly restores is more useful than the other takes much time.
Catastrophe:
The network must be protected by fire,earthquake or theft. There may be a system for back up of network software.
Security:
Network security isues include unauthrized access and viruses.
Unauthorized Access:
On a network there may be sensitive data, therfore it must be protected by an unauthorized access. It may be user identification and password or at higher level it can be encryption techniques.
Viruses:
As network can be accessed at many points, it may have computer virus. A virus is a code that damages the system. A good network must have the virus protection by hardware or software based.
