Lesson 1 Review: Overview of Local Area Networks
The purpose of this activity is to reinforce what you have learned so far about local area networks technologies.

1. What are the main architectural components of a LAN? (Minimum word count: 60)

There are several main architectural components of a LAN. Included is the physical topology of the network determining how the nodes on the network are connected. Access methods are needed on the network to determine how the nodes will access the transmission mediums. The networks transmission techniques and the transmission media determine how the information will be passed throughout the network and if the network will use cables or be wireless. Protocols are a main component of a LAN because they lay out how the various machines will communicate between each other. The LAN’s interconnectivity is another main component because it determines how the information on its own network will be shared with other types of networks.
2. Describe the function and characteristics of a network operating system (NOS). (Minimum word count: 100)

The network operating system (NOS) allocates resources throughout the network and allows sharing of services to its clients. There are two different parts of the NOS, the server portions and the client portions. The server portion of the NOS will be more complex than the clients because that runs the servers and consists of many more tasks. The server portion of the NOS will have many functions to include the management of all the clients on that network. The server will provide shared access between the clients such as shared files and media on the server. It will also provide internet access to its clients. The client portion of the NOS will be run on the client’s machine and allows the client to join the network. It will also allow the client to access the folders and files

(Minimum word count: 100) A network operating system (NOS) manages the resources used within the network and enebles select services to select nodes. A NOS consists of two main components: a server component and a client component. The server component is the most complex component that runs on the server. The server component can do many things, to include; manage multiple users, provide access to files and printers, provide internet access, and enforce network security protocols. The client component runs on the client machine and enables the client to participate on the network. A NOS client component...

What are the main architectural components of a LAN? (Minimum word count: 60) The main architectural components of any LAN starts with the layout for how the nodes connect, the access method (which is how the node gain access to a transmission medium), the transmission technique (which is how the information passes through the network), transmission media (which is defined by either wired or wireless connections), the use of very specific protocols (which are sets of rules that define how the computers communicate and define the LANs interconnectivity), which then determines how the LAN shares information. 2. Describe the function and characteristics of a network operating system (NOS). (Minimum word count: 100) One of the biggest differences between a Network Operating System and a regular operating system is that unlike the OS which can run a single computer, the Network Operating System can run multiple computer on a network at once and allow the network to continue running. The Network Operating System is an essential element of the LAN that can consist of server components and a client component. The server components have multiple responsibilities that can range from managing multiple users on a network, providing access to file...

(Minimum word count: 60) There are six parts to the to the LAN architecture components which include the network’s physical topology, the access method, the transmission technique, transmission media, protocols, and LANs interconnectivity. The architecture is the layout of how the network will be connected. The access method is how a particular node (network component) will gain access to a transmission medium. The transmission technique is how data passes throughout the network. Transmission media is the connection to the network whether it be wired or wireless. The protocols are the set of rules that defines how the nodes will communicate with each other. Last but definitely not least is the interconnectivity which determines what and how information is shared. 2. Describe the function and characteristics of a network operating system (NOS).

(Minimum word count: 70) The function of a firewall is to control the flow of information between the internet and private networks. The function of a firewall within a network is similar to a barrier door or gate. It serves as the first line of defense and assists in preventing network attacks. Another way to think of a firewall would be a security guard or metal detector. As information is passed to and from different networks, the firewall is inspecting and looking out for suspicious content. 3. Which tunneling protocols are commonly used by VPNs?
