Unit 1 Seminar Option 2 2

My name is Alex Brown and I am from Des Moines, Iowa. I would say that I am at a 1 for my networking skills but I have been looking for books to read to broaden my knowledge. A brief overview of the expectations for the course and assignments was discussed. After the introduction course material, we went over the unit one material.

Unit one talks about the different types of network models and compares how to use those networks within an organization. Also, discussed were the tools that would be required for the course. Those tools would be Visio or Luicdcharts and these are tools that allow the user to create network diagrams. A network is a group of interconnected devices and that allows those devices to talk and transfer information. There are many components that go into a network and network devices. You need the computers which act as the node or host and then you need some form of connection like a physical cable. Computers have network interface cards that allow them to transmit and receive that information to and from other nodes. There are many benefits to having networked devices such as email, file sharing, and VoIP. Most organizations will classify a network according to the role it plays and how the network operates.

Peer to Peer networks allows users to connect to each other to transmit information and was used for popular music sharing sites. In a P2P network hosts have no specific roles and these networks are usually easy to implement but hard to scale and support. Another network type is a Client/Server network where the hosts have a specific role. Client/Server networks are a lot easier to scale, support, and protect but very costly and usually require advanced planning to implement. Client/Server networks are usually used by large organizations because of the protection and services that can be offered. Also, discussed was a list of terms commonly used in networking. There are also different types of network topologies that were mentioned during the seminar. Physical topology is a layout or how the physical devices are connected, and logical Unit 1 Seminar Option 2 3

topology is how the data is transmitted or how the devices communicate. There are also different connection types such as a bus, ring, mesh, or physical star. A bus is when all devices are physically connected by a cable and a mesh is each device is connected to the other devices.

Many different topics were discussed during the seminar but the main overview was

about the different types of networks and how the different types of topologies associated with those networks.
