Networking Case Study

It is in most cases used to connect multiple local area networks together to form a bigger network.

According to (Burke, 2004),A switch is a multiport bridge. When a switch receives a frame (A data packet with address and other protocol information embedded), it amplifies the signal, looks at the MAC address to determine which port should retransmit the frame to get it to the intended network device and sends it to that port. The switch can be configured to disconnect any attached device, to discard frames intended for an attached device, to send frames with a specific hardware address to another hardware address instead and to copy a frame to a mirror port which can send it to an attached traffic monitor.

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).

HUB - An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment.

A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).

The reason 2013 intangible assets make up more of the total assets compared to 2013 intangible assets is due to the NDS acquisition that occurred in 2013

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.

LAN Switch- A LAN Switch performs the same work as a hub except that, a switch does not broadcast packets to every computer in the network like hubs. All the computers and computer devices will be connected to the switch by Ethernet cables. The LAN Switch costs $150.

A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.

1. Study the networked supply chain concept as implemented by Cisco. What are its strengths and weaknesses?

When a CPU is composed of two or more processors, each one is referred to as a(n) ________.

This connection point allows all devices that are housed in a building to connect and communicate at an efficient rate. Therefore the employees and students who are able to connect to the network are more productive and but also do not have any cross-talking issues, loss of Internet speed or connectivity issues with other devices like printers and scanners within the network(Cisco).

You are the network manager of a company that has grown from 10 employees to 100 employees in 12 months. Year 2 projected growth is estimated to be 100 additional employees located at a remote location. The aggressive growth has brought about some unique challenges and opportunities. The company has one remote warehouse and no off-site disaster recovery services or servers. The network design remains a non-redundant, flat topology.

The difference between hubs and switches is in how the devices deal with the data that they receive. Whereas a hub forwards the data it receives to all of the ports on the device, a switch forwards it only to the port that connects to the destination device. It does this by learning the MAC address of the devices attached to it, and then by matching the

Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. It is sometimes considered a sub-discipline of telecommunications, computer science, information technology and computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines. There are three types of networks namely: Internet, intranet, and extranet.
