The paper “ Computer Networks and Network Designs”   is a well-turned example of coursework on information technology. Computer networks are classified in a number of ways depending on scale, components as well as a connection method. This paper will give an in-depth definition of these networks and where they should be best applied. IEEE defines standards for the different types of networks and topologies. The most common network used in organizations is the LAN as it only covers a small geographical area. The WAN is most common among campuses and large organizations that extend up to more than one building, for example, a business park.

The OSI and PCP/IP network models will be discussed in-depth in this paper explores the different layers of these models and their functions. Much emphasis will be given to the OSI network model as it is the most commonly used model. The final section in this paper will focus on an example of a network design between the main office and remote site and answer arising questions on what network has been used to set up and describe any limitations that may arise due to the choice of the network. Keywords (Networks, topology, network design) Introduction Each of the previous three centuries was dominated by a single new innovation.

The 18th century was the period of the mechanical systems going hand in hand with the Modern Revolution. The 19th century was the age of the steam motor. In the 20th century, the key innovation was data or information assembling, processing, and distribution. Among different advancements, we saw the establishment of global telephone networks, the innovation of radio and TV, the conception and remarkable development of the PC industry, the launching of satellites for communication, furthermore, of course, the Internet.

As an aftereffect of fast technological advancement, these territories are quickly joining in the 21st century and the contrasts between gathering, transporting, storing, also, processing data are rapidly vanishing. Organizations that have hundreds of offices spread over a wide topographical territory routinely hope to be able to look at the current status of even their most remote station at the push of a button. As our capacity to collect, process, and disperse data develops, the interest regularly advanced data processing develops considerably faster. Components of a NetworkThere are three common and most basic components of a data communications network: Server or host computer: This a machine that provides service to a client.

It stores data or software that can be accessed by a client Client: This is a computer, for example, a PC that is connected to a network and is used to gain access to shared resources on the network. This falls into three major categories: terminal, workstation, and special purpose terminals. Circuit: This is the pathway that allows the transmission of messages.

This can be twisted pair cable, fiber optic cable, or even coaxial cable. Other circuits are such as microwave transmission. Types of NetworksA computer network, otherwise known as a data network is a telecommunications network that allows data exchange between computers. In a computer network, devices that are networked pass data across connections and communicate with each other. The data transferred is transferred in the form of packets.
