L 01 Understanding Networking principles

Network arrangement in an organization might help to decrease the effort and enhance the data safety. The report will discuss the benefits and constraints of network systems and topologies. The report will discuss the impact of technology and standards along with actual application of different networking system. The report will also discuss the role of hardware and software components and control the server and terminal requirement of network. The report will present the network design and will evaluate the network along with implementation, testing of requirements and recommended solutions to possible problems in network. The report will present the network maintenance schedule. htts// 28/05/2017

Task 1.1 Discuss the benefit and constraints of different networking system type and topologies.

Topology is the layout of connecting devices. This object introduces the average topologies of networking.

*Network type


*WAN- wide area network.

*LAN- Local area network.

*WLAN- Wireless local area network.

*MAN- Metropolitan area network.

* Wide Area Network (WAN)A wide area network (WAN) is a network that exists over a large-scale geographical area. A WAN joins different smaller networks, including local area networks (LANs) and metro area networks (MANs). This guarantees the computers and operators in one area that can connect with computers and operators in other locations. WAN application can be done either with the help of the public transmission system or a private network.

*LAN-local area network may serve as few as two or three users (for example, in a small-office network) or several hundred users in a larger office. LAN networking comprises cables, switches, routers and other components that let users connect to internal servers, websites and other LANs via wide area networks. *attention*

*Different type of topologies are-





*Bus topology.

This is a joint backbone to connect all devices with a single cable, the backbone operates in a collective communication standard that devices attach or tap into with a border connector. A device wanting to communicate with another device on the network sends a transmit message onto the wire that all other devices see, but only the intended receiver actually accepts and develop the message.

Ethernet bus topologies are relatively easy to install and don't require much wiring linked to the alternatives. 10Base-2 ("ThinNet") and 10Base-5 ("ThickNet") both were popular Elthernet wiring options many years ago for bus topologies. However, bus networks work best with a limited number of devices.

If more than a few dozen computers are added to a network bus, performance problems will likely result. In addition, if the backbone wire fails, the entire network successfully becomes impracticable.

*Ring Topology

This a topology network where every device has just two neighbours for communication reasons.

All communications go through a ring in the same direction (either "clockwise" or "counter clockwise") in circles. A failure in any wired or device breaks the circle and can take down the entire network.

To connect a ring network, one typically uses FDDI, SONET, or TOKEN RING technology. Ring topologies are found in some office buildings or school campuses.

Star Topology

Many home networks use the star topology. Star network topographies a central linking point called a "hub node" that may be a network hub, switch or router. Devices normally connect to the hub with Unprotected Twisted Pair (UTP) Ethernet.

Compared to the bus topology, a star network usually involves more cable, but a failure in any star ...
