Networking Computers

Advantages & Disadvantages of Networking

Learning Objectives: By the end of this topic you should be able to: describe the advantages and disadvantages of networking computers describe the advantages and disadvantages of networking computers

What is a network? a group of computers connected together a group of computers connected together in order to share resources in order to share resources a computer not connected to any other is a stand-alone computer a computer not connected to any other is a stand-alone computer

Advantages of Networking

share data share data sharing files sharing files setting up an intranet setting up an intranet collaborative working collaborative working

Advantages of Networking share data share data sharing files sharing files setting up an intranet setting up an intranet collaborative working collaborative working share hardware share hardware peripherals such as scanners and printers peripherals such as scanners and printers often higher quality peripherals often higher quality peripherals e.g. only have to buy one printer e.g. only have to buy one printer

Advantages of Networking monitoring of system monitoring of system what are staff working on? what are staff working on?

Advantages of Networking monitoring of system monitoring of system what are staff working on? what are staff working on? central administration central administration accounting and monitoring of resources accounting and monitoring of resources access rights access rights

Disadvantages of Networking cost of network hardware cost of network hardware hubs, switches, cables, server hubs, switches, cables, server reliance on central equipment reliance on central equipment if server crashes, nothing works if server crashes, nothing works requires technical staff requires technical staff cost of employment (hiring network manager, technicians) cost of employment (hiring network manager, technicians) viruses can spread more easily viruses can spread more easily increased risk of hacking increased risk of hacking loss of data loss of data increase in office “chatter” increase in office “chatter” less work done due to messaging, not work related less work done due to messaging, not work related more data traffic = slower working computers more data traffic = slower working computers
