Components of a Wired LAN

You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network.

“Networks are all around us. They are in our walls, in the air. At schools, hotels, hospitals, even coffee shops. Always there, always on…This power exists today. In our routers. In our switches... . (Cisco, n.d.)

An operating system must support a wide variety of networking protocols in order to meet the needs of its users. The user will be able to identify and make sure that various systems and servers are running smoothly, also the user is will if the system is loaded or

In the design, the topology used is a star topology. The computers in every office or classroom are linked to the central device known as the switch. The star topology leads to the expansion of the network without any disruption. This defines the use of a hub, a router or a switch to interconnect various computers together. All the workstations in this topology are connected with a connection of point-to-point to the central device. The data is first passed through the primary device before reaching the planned destination. Hub controls and manages the whole network. The hubs connect several nodes that are present in the star system. The hub acts as the signal booster (Elhakeem, 2010).

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

When it comes to planning an entire system network is not a easy task. We need to explore the options and I plan on covering this in the essay and will go into brief details about several key concepts and explain key points in Peer to Peer (P2P) client / server architecture, web based computing and how network and their protocols are required for successful network implementation.

With admirable foresight, the Internet Engineering Task Force (IETF) initiated as early as in 1994, the design and development of a suite of protocols and standards now known as Internet Protocol Version 6 (IPv6), as a worthy tool to phase out and supplant IPv4 over the coming years. There is an explosion of sorts in the number and range of IP capable devices that are being released in the market and the usage of these by an increasingly tech savvy global population. The new protocol aims to effectively support the ever-expanding Internet usage and functionality, and also address security concerns.

4. Identify the network protocols that are used in the protocols that are in the local are network at your shall or workplace. Why were these protocols chosen for your network? Was IPX ever implemented in your local area network? Why? if your network is using IP, what address class(es) is being used? Why? see if you can find out if and how class D and class E addresses are used in your network.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

The two TCP/IP transport layer protocols (TCP and UDP), are very crucial for the smooth operation of network services for both the computer applications and application layer protocols such as HTTP, FTP, SMTP and Telnet. These two transport layer protocols TCP and UDP execute these services via the employment of IP. They use IP in the efficient routing of packets to their respective destination networks (Steinke,2001).The TCP is further noted by Steinke (2001) to be responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery while its counterpart UDP is noted to be responsible for the provision of a connectionless but rather unreliable packet delivery. In this paper we explain the work of the two TCP/IP transport layer protocols (TCP and UDP). In addition, describe how TCP and UDP manage key functions such as reliability, port addressing, and segmentation.

The Modern Mouldings current wired infrastructure will be appraised based on the following qualities. Speed, Topology, Scalability, Cost, Reliability and Availability.

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.

Introduction: The devices on one or more LANs can be configured to communicate as though they were directed connect referred to as VLAN (Virtual Local Area Network). They are located various geographical areas. Since VLANs are taking into account intelligent rather than physical connections, they have a great degree flexible. VLANs characterize broadcast domains in a Layer 2 network, in which the broadcast domain is the arrangement of all devices that will get broadcast frames which originates from any device inside of the set. Broadcast domains at time have limitations by routers that don 't forward broadcast frames. Layer 2 switches broadcast domains regardless of the setup of the switches. Switches permit one to make numerous broadcast domains. Every broadcast domain is similar to a particular virtual bridge inside of a switch. [1]
