ICT II Networking. Advantages and Disadvantages
ADVANTAGES OF NETWORKING Speed – Sharing and transferring files within networks are very rapid, thus saving time, while maintaining the integrity of the file Cost – Individually licensed copies of many popular software programs can be costly. Networkable versions are available at considerable savings. Shared programs can easily be upgraded on the server rather than on individual workstations. Security – Sensitive files and programs on a network are passwords protected against illegal copies.
ADVANTAGES OF NETWORKING Centralized Software Management – Software can be loaded on one computer (the file server) eliminating the need for the software to be added on independent computers throughout the building. Resource Sharing – Sharing of printers, fax machines, etc. Flexible Access – Files can be accessed from computers throughout the firm.
ADVANTAGES OF NETWORKING Electronic Mail – E-mail aids in personal and professional communication. E-mail will enable staff and students to communicate within the building and or classroom without having to leave their desks. Workgroup Computing – Workgroup software allows many users to work on a document or project concurrently.
DISADVANTAGES OF NETWORKING Server problems stop an application from being available. Network problems can cause loss of data. Network problems can lead to loss of resources. User work is dependent upon the networking. System is open to hackers.
DISADVANTAGES OF NETWORKING Decisions tend to become centralized. They could become inefficient. They could degrade in performance. Resources could be located too far from users. Network management can become different.
DISADVANTAGES OF NETWORKING Cabling can be expensive to install and replace. A fault with the server will prevent the whole network from working. Security measures are needed to restrict access to the network. WANs are vulnerable to hackers and viruses.
