Far beyond our imagination, people today are living in what we called an information era, where in information significantly play a great role in almost every aspect of our lives. We communicate in various forms in order to capture information relevant to every organization or individual to support day to day transactions and activities. People today in different locations utilized the advancement of technology, where in digital and electronic devices were sprouting everywhere supporting human network. Cell phones, computers and ipads were just a few to mention. But the question is how these particular devices interact to each other in data network or data communication?
In order to send and receive message, a connection between two or more devices should be established and intermediary devices are needed to guide the message to the destination. Since Ethernet is the predominant LAN technology in our modern generation it should be complimented with the right and proper connection, intermediary device and the type of media in order to create or assemble a functioning network.
The pathway or the passage way where the data passes through in order to arrive in a fast, reliable and consistent manner is always dependent to the type of media used in a network. Therefore there is a need to examine the type of media their roles and how they function in different environments. Before designing a network, a type of media is important to establish a connection and in order to maintain a concrete connection there should be development management connection.
The type of media, the right cable to use and the associated connectors were subject to consideration in designing a network whether it uses a wireless, fiber optic, or copper connection. There are a lot of factors to consider in choosing a media. The first thing we should put in mind is the usability of the media, does it conform or define the needs and requirements of an organization? The second thing is the cost when choosing a media, the geographical location and the building structure. The selection of devices and the design of the network addressing scheme is also important in a LAN or WAN network. The appropriate device or intermediary devices just like routers, switches and hubs greatly affect the performance of the network. Making a LAN and WAN connection must be based on the needs and type of organization and recognizing the number of hosts in a network must also consider future expansion or growth and must depend on the number of end devices on a network. Subnetting is also helpful in order to reduce broadcast traffic. Subnet design helps to improve performance of the different departments in an organization, because one subnet may serve for a particular function. Addressing scheme is also helpful in facilitating configuration and troubleshooting of a network by this every device assumes a particular function just like a general user, administrator computer, a server and intermediary devices can easily be recognize through the help of addressing scheme. In designing a LAN Or WAN network there must be a consideration on the location where those network devices must be placed, example to this is the telecommunication room where intermediary devices were placed and maintained. The working area also, because it can affect to the performance of a network, especially if the working area where cables and other media are placed are exposed to various interferences just like electromagnetic and radio frequency interference. The performance of each device on a network is greatly dependent to other devices, to the design, location and building structure of an organization
