Nt1310 Unit 3 Network Architecture

During this section of my blog you would be able to view all the different types of typical services provided by networks and the purpose of each where I discuss the advantages and disadvantages of them all.

LANs, WANs and on the internet, and provide data storage independent of the location. ! !

4. Which TWO (2) of the four network types (e.g., LAN, WAN, Wireless LAN and MAN) might

Since every computer is going to be connected to a centralized node which usually are hubs or switches the topology can be defined as a star topology. The network design layout for the Adelphi building each node is going to be connected to a switch instead of using hubs.

First, we need to understand the difference between logical and physical topographical layouts. Logical layouts are how the data move across the network and physical layouts are how the network relates to its wires and hardware (Kevin Wallace, 2012). Note that how the data moves through the network is not going to be the same as how the data is physically structured (Michael Harris, 2008). The most coming physical topologies are Bus, Star, and Star-Wire Ring (Kevin Wallace, 2012). The most coming logical topologies are Bus, Ring, and Star (Kevin Wallace, 2012).

A complete topology layout for a network covers an end-to-end networking solution. The design of the network has to

The idea of an ad hoc network is often unfamiliar to end users who have only seen small residential or business networks that use a typical router to send wireless signals to individual computers. However, the ad hoc network is being used quite a bit in new types of wireless engineering, although

This has similarities with enterprise networks since they both follow the same architecture. The network is consist of the following:

There are three major types of network topologies; bus network, ring network and star network. The topology of a networks is the virtual structure and how the devices are connected to each other. As mentioned, this structure is virtual and the physical structure may not correspond with the name, for example a network set up in a straight line at an office may have a ring topology, not a bus topology.

The basic concept of network convergence is to provide all the communication services such as voice, video and data within a single network to achieve its goal of delivering better services while lowering prices to consumers. There is a need for network convergence, as one single pipe is used to deliver all the communication services that help in regulating the overall network costs to a significant level. Both the users and service providers get benefitted by the adoption of convergence. The users can access a huge range of services, where as the service providers can benefit by entering into new markets. The network built on Ethernet allows users to access their applications on servers and the network built on Fiber Channel enables those servers to access huge amount of data on a storage network. The manufacturing cost and maintenance of these two networks is very expensive and hence it would be more cost-efficient to have just one network. So the converged network assures a highly scalable and a high-performance network with consistent management tools that can handle both Ethernet and storage traffic. Convergence is all about services and new ways of doing business as well as interacting with society.

Network Topology is how computers, printers, and other devices are connected over a network (“Guide to Network Topology”, 2015”). The word topology means shape and the term network topology refers to the shape of a network (“Guide to Network Topology”, 2015). Network topologies refer not only to the physical layout of the devices connected but how the devices communicate to each other (“Tomsho, Tiffel & Johnson, 2004, pg 48”). There are several different topologies and the choice of a topology is determined by how the network works. The network cabling system carries all the data from one point to another and the design is determined by how the network should function, the reliability and how accessible the network should

Wireless mesh network is a topic that is being studied and researched in academia and industry extensively. This has added mobility to access to the Internet. In a wireless mesh network, the nodes are interconnected through some predefined set of gateways. Gateways are same as other nodes with some special features. A wireless mesh network consists of several multihop and wireless routers. These routers

Information and communication technologies have become advanced and efficient in last few decades. The improvement is radical and it has made the broadband technologies and internet more robust and wide spread. Internet has become an integral part of any communication technology. It carries various type of information and offers different type of network services. The speed of data transmission has also improved. [1]Now days, Internet can be accessed from any smart phone, PDA, laptop, computer and several other smart devices. Wireless internet connection through wireless LANs at public places like airports, stations etc. All these have led to the wireless mesh network. [2]

Ring- In a ring network layout, all the computers are connected to each another in a circle formation. The data passes

Networks are classified on basis of scale. The area a network covers determines the type of network it is. Originally, there were only two types of networks: LAN and WAN. But over the years, other types of networks have evolved, like MAN, SAN, PAN, CAN and DAN. Let’s take a look at the more popular ones:
