Case Study On Computer Networks

1)A network is when two or more computers are connected together and are able to share data and communication.

* Smart Hub (Intelligent Hub) function is similar to Active Hub, but more integrated chips have the ability to automatically detect errors - very useful in case detection and error detection in the 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.)

transmission of structures to generate digital indicators distorted by the loss of the transmission. Hubs function as repeaters by transmitting messages to the related computers. The repeater does intellectual routing that can be acted upon by routers and bridges (Vachhani,

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.

The first topology represented is the Ring topology. A ring topology is a network in which all traffic moves in only one direction because of this the speed is faster than some other topologies, even as network traffic increases. Due to the configuration of a ring topology the resources of the network are available to every device and the cost of setup can be lower than some of the more complicated topologies. However, the configuration of the Ring topology is also a disadvantage. Since a file sent to any device within the network has to pass through every device, if one device fails the entire network goes down. (Ethernetpedia)

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.

Network Devices: Network devices include all devices, which help make a network workable. These include Hubs (Enables more than one computer to interconnect on a network), Routers (Connects two networks), Switch (Joins multiple computers within one LAN and a Bridge (Allows one network to connect to another

Information exchanged between two hubs goes through the hubs introduce in the middle of the source and the goal hubs. For overseeing topology, a different focal server is not required. (UKESSAYS, 2015)

In a star network, all cables or nodes are connected to one central core which is the hub. This tends to be the most reliable topology.

The biggest disadvantage of a star topology is the central connecting point, in this case the router. If the router goes down it affects all of the connected devices. The size of the network is directly affected by the capacity of the central connecting device. The efficiency of the network is also directly affected by the central connecting device. If one device on the network is using a large

The devices of such a network are often situated physically near one another and are suited for homes and small businesses as they are easier to set up and use. It is only natural that, computers in a peer-to-peer network run the same networking protocols and software. There is no central location for

Generally, every component in a network is called a node. Each node is further identified by the specific task it performs. A user's node is called a terminal or a workstation. This can be a "dumb" device, meaning it has no operating system, just a monitor and keyboard, or a "smart" node, meaning it can do it's own computing because of an internal central processor.

The ability to send and receive data efficiently is the most important objective of networking computers.
