1. A family wishes to connect several devices to share an internet connection and a Bluetooth wireless printer. They have three personal computers. One is in the same room as the printer. The other two are together in another room. In addition, they want to utilize the network for an internet-enabled television and a VoIP phone.
• Describe what network device or devices you would recommend they purchase and explain why.
My recommendations for this family are to subscribe to a cable internet or DSL service provider. They will need a modem which acts as the gateway for their network. I would have then purchase a wireless Concurrent dual band 802.11n router and wiring that connect the modem to the router. This would allow them to connect

File serving allows users to share information over the network. The main purpose of a file server is to reduce the amount of storage programs, applications, and files take up on a client’s workstation. A file server can also house database table information (White, 2011).
Mail serving is a computer that keeps a record of each email that goes in and out of the network (White, 2011).
Print serving usually a computer that is connected to one or more printers that other client workstations can connect to, that accepts print jobs and sends them to the appropriate printer or assigns the print jobs the appropriate priority (White, 2011).
Video/media serving this allows for streaming of videos on demand, and for the storage, and recall, of digital media, including pictures, music, and videos (White, 2011). Monitoring and Distributed Processing can s be utilized to monitor network resources and health, but when workstations are idle, the processor’s power can be put to good use by applying that power to other processes, thus by increasing overall efficiency (White, 2011).
• Show which of these applications would you combine together on a single server and which you would use separate servers for. Explain your choices of which to combine and which to leave separate.
The applications I would combine are the mail serving, file serving, video/media serving because combining these file will save a lot of
Once one of the computers is properly configured as a file server, users can access the storage by mapping the drives on the respective computers. The file server will be mapped as a drive and users can store, edit and access files directly from the shared storage disk. The disk will be connected to each computer. For example, when a user needs to access any file from the file server, he/she can access the drive that will now be mapped on the every computer (Science - Opposing Views, 2014).
That means that with the network operating system we can have lots of users all concurrently using resources on our serve.One of the most important aspects about server operating systems is the security. Workstation OS provides great security for end-users, but it's still not as tight as the security offered by the network operating systems. The reason for that is that with the network operating system were providing services to hundred or thousands of concurrent users. Therefore security is critical Workstation operating systems also provide some type of authentication by using user names and passwords which reside on local database on the local
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.
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.
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.
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.
Uses a modem which can provide both wired and wireless connections for a number of devices
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.
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.
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.
This type of computing even makes use of other resources such as SANs, network equipment, and security devices. It can also support applications that are accessible through the Internet. These applications make use of large data centers and powerful servers that host Web applications and Web services.
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
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
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.
