Task 1 Introduction What is a network? A network can be defined as two or more computers which are linked together to share resources. These resources can include internet access‚ printers‚ software and files. The ‘heart’ of a network is called the server‚ and its function is to contain all the software and services which the network and its users depend on. [pic] Figure 1: Example of a basic network The server is operated by personnel called Network or System Administrators

protocol that has a transmission speed of 1 Gbps. Gigabit Ethernet is primarily used for backbones on a network at this time. In the future‚ it will probably be used for workstation and server connections also. It can be used with both fiber optic cabling and copper. The 1000BaseTX‚ the copper cable used for Gigabit Ethernet‚ is expected to become the formal standard in 1999. What topology is most appropriate for the LANs and the WAN? What are their merits? Either the bus or the star would work for

channels of information over longer distances with fewer repeaters required. *Size and weight Optical fibre cables are much lighter and thinner than copper cables with the same bandwidth. This means that much less space is requires in underground cabling ducts. Also they are easier for installation engineers to handle. *Security Optical fibres are much more difficult to tap information from undetected; a great advantage for banks and security installations. They are immune to Electromagnetic interference

ISO/OSI Reference Model: Open Systems Interconnection (OSI) is an effort to standardize networking that was started in 1977 by the International Organization for Standardization (ISO)‚ along with the ITU-T. The world has not always been so simple. Once upon a time‚ there were no networking protocols‚ including TCP/IP. Vendors created the first networking protocols; these protocols supported only that vendor’s computers‚ and the details were not even published to the public. As time went on
