Nt1310 Unit 3 Assignment

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.

It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects.

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).

A star topology is a type of network topology, a workstation is able to send information

In a full switched network, hubs are not used. Instead, switches are used with a dedicated segment for every node. In this type of network the switch picks up every transmission before it reaches another node. Since any segment only reaches a single node, the frame only reaches the intended recipient. This allows many conversations to happen at the same time. Switching also allows a network to maintain full-duplex Ethernet, which allows information to travel from node to switch and switch to node at the same time. Most networks do not exclusively use switches because of the costs involved with replacing all hubs. A combination of switches and hubs are typically used to create an efficient and less costly network (Tyson 2001).

a.) The Graph for HubAndSwitch is almost identical to the OnlyHub scenario as observed in the following Graph for the Traffic Sent (Packets/sec):

A hub and spoke infrastructure starts with a wireless controller that is connected to all access points on the network by wired connections. All of the changes and data are processed on the controller and then pushed to the access points as the

Star topology is one of the most common network setups. In this arrangement, every node connects to a central hub, switch or computer; the hub acting as a server and the peripheral devices as clients. A major disadvantage of this network topology is that if the central hub fails, all of the connected devices are disconnected. In a star network layout, each workstation is connected by its own cable directly to the server. Star networks are usually the layout of choice in schools and offices because they tend to be the most reliable of the topologies. The visual example shows how this setup gets its name as it is shaped very much like a star.

The main objective of this lab is to design a network with and without switches and examine the network’s parameters in both the scenarios. Two such scenarios were created: 1) Only hub (where one hub is connected to 16 work stations) 2) Hub and Switch (where 8 work stations are connected for two hubs and a switch connecting them). Here, a hub is a device which

Is a high speed data transmission which only one cable can carry a large amount of data at once.

In this document I will be detailing the different common network components which make up a network, connecting all the various devices together. Each device has a separate use; however, some devices can replace or supplement others.

In simple words, it can be explained as a method used for transmitting information over the lines between electronic devices. The device asks the information is called the Modbus Master and the devices supply information is Modbus Slaves. In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the

Each computer in a network has a special expansion card called a network interface card.

Star network – client server architecture each workstation is connected by its own cable straight to the server. They are usually used in places like a school and office as they are the most reliable topology. They are most reliable because if one connection fails for a user it does not affect others. Data collisions is a rare thing. It also has good security no workstation can interact without going through the server first. Topology for a LAN all nodes are linked alone to a central connection point such as a hub.

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.
