Networking Essays (1661 words) - Server, Server Hardware

Networking For my independent study, I have created a network in my house. A network by definition are more than one computer that are linked together electronically via a protocol (common language) so the computers can communicate and share resources. This network improves the day-to-day life by adding value and usefulness to the computers. The processes and ideas that I have learned thru this experience can be applied directly into todays rich electronic business environment. Identifying the needs of the user is the first step for building a well-designed Network. A professional installation was needed to maintain the aesthetics of the rental house. Most of the wires are run in the attic and then down plastic conduit attached to the wall. The conduit is run all the way to the wall boxes where the Ethernet ports are located. Every wire is clearly labeled and included in an easy to read schematic of the house. This way future tenants will have the ability to utilize the network. Next, every room needed to have access to the network. In order to minimize the overall use of wires, hubs were placed in strategic locations. An 8-port 10/100-megabit auto-sensing hub is located in the computer room and a 5 port 10-megabit in the sound room. There, needed to be docking stations, so laptop users or visiting computers could easily plug into the network and utilize the pre-existing monitor, keyboard, and mouse. These are the basic needs that have been put into the des ign of the network. Each computer setup is unique with certain strengths and weaknesses. The network takes advantage of the strengths of each individual computer and makes them available to all users. A network essentially expands the capabilities of each computer by increasing functionality thru resource sharing. In the house, there are a total of four computers and two laptops. Processing speed and an abundance of ram is not essential for a server with such low traffic. Thus the most antiquated computer was elected for this function. Between all the computers, we have several extra pieces of hardware such as a zip drive, CDRW, DVD ROM, scanner, and multiple printers. Each piece of hardware is dispersed between the computers. There were several immediate efficiencies that occurred when the network went operational. The zip drive is located on the server while the CDRW is located on one of the individual workstations. Previously, if the need arose to burn some information stored on the zip disk to a CD, the individual computers were practically worthless for this task. However, with the network, one can map a network drive on the computer with the CDRW to the zip drive on the server. This allows information to be efficiently transferred from the zip drive to a CD. In addition, the server also has a scanner attached to it. The problem is that the server is too slow to handle sophisticated photo editing software. Now an image can be scanned on to the server and then a faster computer can be used to edit it. There are 3 different printers, each varies in quality, speed, and maintenance costs. The most expensive one is reserved for only making color photos, and the other two are used for everyday printing, one of which is much faster and has more reliable paper feeding. A user can easily choose a printer depending on their needs. This network takes full advantage of each computer through resource sharing which ads tremendous value for its users. In Business it is important in any network to be able to restrict access to individuals private files or directories. Security would demand that not all users would be allowed access to highly confidential information. There is other information that would be made available to other users on a read only basis. The same is true of the users in my network. Microsoft developed NT to be very secure. Most of this security is devoted to protecting network resources and the filing system (NTFS). The administrator decides who gets access to which resources by setting up users and user groups. Each person is asked to choose a user name and password. Then the administrator identifies the needs and privileges of each individual user.
