Key Components Of The Network Essay

It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).

Match each description to its plan by writing the description's number in the appropriate blank. Some descriptions may apply to two or more plans.

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).

All stations are connected by cable or wireless to a central point, such as hub or a switch. If the central node is operating in a broadcast fashion such as a Hub, transmission of a frame from one station to the node is retransmitted on all of the outgoing links. In this case, although the arrangement is physically a star, it is logically a bus. In the case of the central node acting as switch, an incoming frame is processed in the node and then retransmitted on an outgoing link to the destination station. Ethernet protocols IEEE 802.3 are often used in the Star topology LAN.

A Star topology is the second type of topology represented. This topology is easy to install as well as being easy to expand by connecting additional nodes or devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices need to be added or removed, it does not cause disruptions to the network. This type of topology is used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

Team “C” was hired by Riordan Manufacturing management to overhaul the security features currently employed by the company. Management outlined a comprehensive plan that included a complete hardware refresh, security best practices and end user training. Team “C” will devote resources to assess the physical and network security issues and concerns at each Riordan plant. Once those have been identified, Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally, Team “C” will address web security issues and concerns present at each Riordan plant and recommend a way forward for the company.

The work that will be performed will include the design and installation of a fully switched star network. This includes the installation and setup of all the network devices, cabling and interfaces but may be limited to workstations, devices, servers, switches, routers, racks and all related software.

Fiber optic cables will be installed and configured on the physical star network topology spread throughout the 600 user network infrastructure. The main equipment that will be used during the implementation of the physical star topology will be the patch panel with an array of RJ-45 female connectors with terminals to connect wires to all the 600 users across the network infrastructure.

• A failure in any cable or device breaks the loop and can take down the

Star – All computers and devices are connected to a centrally situated hub or switch. The hub or switch collects and distributes the flow of knowledge at intervals the network. It’s higher to use a switch than a hub as a result of a switch transmits the info to the supposed recipient instead of to all or any hosts on a network.

To solve these problems a company can implement Wi-Fi on their network. This can reduce the price of implementing additional cable in the network.

“Right now, it’s an industry dedicated to one thing. Profit.” This quote by author, Paddy Chayefsky, perfectly sums up the motives behind the movie “Network.” From hiring soothsayers to risking a man’s mental heath for the sake of a successful television program, the characters in “Network” have truly been blinded by fame and top ratings. This satire fiercely describes just how far a television network will go to achieve such accomplishments.

ESET NOD32 Antivirus- an Antivirus is software that is used to prevent, detect, and remove malicious computer programs. ESET NOD32 Antivirus is a good choice since it also acts against other types of malware such as worm, Trojan horses, backdoors, and spyware. The ESET NOD32 Antivirus 6 that I will utilize

Define the situation (case summary) Define the major issues, conflicts, and the network . Describe the options (alternatives) for solving these issues. Several internal and external influences serve as contributing factors in the reconsideration of the company’s current system. Changes in customer demands, domestic and global competition, and a unique decentralized management system is now forcing the Westminster Company to reevaluate their traditional supply chain practices. (Bowersox & M.B., 2014) Westminster’s domestic operations consist of three separate companies that sell and distribute products to several of the same customers. (Bowersox & M.B., 2014) At first glance consolidation of the systems can significantly improve

The proposed network is designed for the UMUC new building in Rockville. This new building will have some administrative offices, lecture rooms, library, and computer labs with an open Wi-Fi. This new building will have total six computer labs that will be used for instruction. Each of these labs will have 25 computers, 23 student computers and one instructor computer, one server in the closet and in addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students for doing their own purpose like homework. In Student Computer Lab there will be 30 computers and a server in the closet. There will be 10 computers for student’s use and 5 computers for Library staff in the library so they can access to the library resources for staff use, with the exception of the admissions office, which will have five computers. There will be six class room which will have a computer for instructor’s use. Finally, there will be 7 offices in the building and each of these offices will have one computer. There will be two server rooms, one on the first floor and another one on the second floor. There should be at least 3 separate networks: Administrative, Instructional, and Public. All staff-accessed computers will be on the
