Produce a report for the Managing Director of Animal World Magazine outlining different ways of implementing a client-server Local Area Network (LAN) for the business. This includes; * Topologies o Cables o Connector o Hardware o Software o Advantages and Disadvantages * Network o Advantages and Disadvantages * TCP/IP o Advantages and Disadvantages * IP Address o Advantages and Disadvantages * MAC Address o Advantages and Disadvantages What is Network? A network is a collection of terminals, computers, servers, and components which allows for the easy flow of data and use of resources between one another. The three basic types of networks include: o Local Area Network (LAN) o Metropolitan Area Network (MAN) o Wide Area Network (WAN) LAN - A Local Area Network (LAN) is a network that is confined to a relatively small area (in one building). MAN - A Metropolitan Area Network (MAN) covers larger geographic areas, such as cities or school districts. WAN - Wide Area Networks (WANs) connect larger geographic areas, around the world therefore is world wide. What is Topology? The topology describes the way in which the devices on a LAN are connected together. There are four main LAN topologies: bus, star, ring and mesh. Bus A Bus topology is a single wire with terminator at each end. All nodes (server, workstation and peripherals) are connected to single wire in logically. Bus topology is also known as bus network which was the original form of Ethernet network. Ethernet on bus topology uses coaxial cable. The cable can be in two different types 10Base5 and 10Base2 which are thick and thin. Both cables communicate at the speed of 10 Mbps. Termination is important in bus network because when signal is transmitted it travels in entire cable. Without the termination when the signal reaches the computer it bounces back and travels back up the wire. The termination absorbs the electrical energy and stop reflections. ...read more.


107 Purpose of the Internet Protocol (IP) o The IP protocol transfers the data used throughout a TCP/IP Internet. o IP software carry's out the routing function. o How hosts and routers should process packets. o How and when error messages should be created. Advantages of IP Address o It is currently used on Internet o It is supported by current stacks o It works with current DNS and DHCP servers Disadvantages of IP Address o Less space because running out of addresses only 32-bit o Lack of auto configuration o Lack of security support MAC Address MAC (Media Access Control) is an address given to device in a network. It consists of a 48-bit hexadecimal number (12 characters). The address is normally assigned to a device, such as a network card, when it is manufactured. Advantages of MAC Address o It contain broadcasts o It filters when needed by protocol Disadvantages of MAC Address o It's slow because each packet intensively processed o It's complex o It's expensive especially for higher bits 100Mbps and 1Gbps Network Cabling Cable is a piece of wire where information usually flows through from one computer to others. There are several types of cable which are commonly used with LANs. Some network utilize only one type of cable, other network uses a variety of cable types. The type of cable is depending on network topology, protocol and size. Unshielded Twisted Pair (UTP) Cable There are two different types of Twisted Pair: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks The cable has four pairs of wires inside the covering. Each pair is twisted with a different number of twists per inch to help reduce interference from next pairs and other electrical devices. The tighter the twisting, the higher the supported transmission rate and the greater the cost per foot. ...read more.


less traffic on network o Makes saving on the hardware upgrading Disadvantages o Requires initial investment in server o Retraining required o Large network will require a staff to ensure efficient operation o If server goes down then it will stop communicating with each other and stop sharing resources o Software costs for both server and client Examples of network operating systems Below list are some of the popular peer-to-peer and client/server network operating systems; * AppleShare - It includes both server and workstation software. * Microsoft Windows Server - A better version of Windows 2000 that provides a powerful client/server network operating system. * Novell Netware - Most popular client/server network operating program. Netware can handle any size of network. NOS OS Required LAN type Novell NetWare DOS Client/server Artisoft LANtastic DOS Peer-to-peer Windows 95/98 Windows Peer-to-peer Windows NT Windows NT Client/server Banyan Vines UNIX Client /server OS/2 Lan Manager OS/2 Client/server Which network will be appropriate for Animal World and why? Star A Star topology connects the computers by single cables to a central unit, usually a hub. Star is most popular nowadays for businesses. Animal World only has 10 computers and I think that star will be better for them because they can communicate with each other directly without waiting unlike token ring. They can also share resources such as printers, scanners etc in star network through Hub. Animal World can expand their network without disrupting other computers. Cables and Connector CAT5 and RJ45 are the cable and connector used in Star network. Hardware Hub is the hardware that is used in star network. It is essential that hub is needed to connect the computers together in star network. Software Client- Server is the software that is used star network. Protocol Ethernet is the protocol used in star network. Drawbacks Single point failure hub can shutdown the network from communicating and sharing. Star network is expensive because cables are connected from each node back to hub. AVCE UNIT 23 10/05/2007 1 ...read more.
