Fundamentals of Local Area Networks Essay

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

Server state can be divided into two part : the stateful and stateless server. The stateful server is that when a client open a file the server gives that client an unique identifier and stores client’s information into its memory. Although this method can improve performance, however, stateful server is generally be avoided in distributed system. On the other hand, stateless server uses totally different mechanism that the server identifies the file information and client position in each request but save nothing into its memory. The advantage is that it is easier to use fault tolerance on stateless server.

This allows you to share centrally stored files to all of your connected computers easily. It also makes sharing a printer much easier than transfering everything to one computer as a gateway.

1.17 Consider a computing clusters consisting of two nodes running a database. Describe two ways in which the cluster software can manage access to the data on the disk. Discuss the benefits and disadvantages of each.

The devices that need to connect are workstations, wireless access points, security cameras, servers, phones and printers, with enough available bandwidth between buildings and devices. The wireless network itself will be able to handle multiple devices and there needs to be enough coverage throughout the campus, including the outdoors. Separate wireless network will need to be establish to ensure that guest traffic does not affect church network traffic.

Permits the PC to perform different assignments send and get email, turn upward sites, and so on

1. Thanks to Wi-Fi technology, this devices can connect wirelessly and seamlessly to one’s existing broadband connection in seconds.

This scenario is an example of using an access point, which a lot of people currently use to be able to access the internet via WiFi,

Uses a modem which can provide both wired and wireless connections for a number of devices

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

If you have multiply users and a small scale of applications you would use the two tier client/server architecture. This would be an example of anyone that uses the

To ensure maximum flexibility and reliability I recommend that the network be configured as a wireless only network. The number of devices is relatively small; two workstations, one printer and one router

Distributed computing is an improved innovation to run organizations. Rather than running the applications on a PC or a LAN, they keep running on a common multi-occupant.

A server is a node on the network that provides services to the users of that network. A server will manage hardware and software resources or monitor the exchange of information through a network. Each server will respond to the requests of a user and provide a service, like printing a document or retrieving a stored file. There are two basic types of servers: Dedicated and Non-dedicated.

All the devices will be connects with a switch. In computing centre server room, there have multiple switches which connected with multiple servers and PCs. All the switches from various department will connect to the switches which located in computing centre server room. Let say, a staff want to print some document which from File/Printer Server, his/her computer will connect to the switch which locate in particular department, the department’s switch will connect to the switch which locate at computing centre server room and connect to the File/Print Server. After he/she selected document which want to print, the documents from server will send the document to the printer through switches and print
