Advantages of Installing a School Network
File Sharing - Network file sharing between computers gives you more flexibility rather than using floppy drives or Zip drives. you can use the network to save copies of your important data on a different computer, examples share photos, music files and documents.
Sharing Devices- Sharing devices is another benefit in which a network exceeds stand-alone computers. For example laser printers, fax machines, modems, scanners and CD-ROM players, when these peripherals are added to a network, they can be shared by many users.
Sharing Internet Access- In computer network, students can access the internet simultaneously.
Speed- Using a network is faster way for sharing and transferring files. Without a network, files are shared by copying them to floppy disk.
Cost- Networkable versions of many popular software programmes are available at considerable savings compared to buying individual licensed copies. Its allows easier upgrading of the program.
Security- Files and programmes on a network are more secure as the users do not have to worry about illegal copying of programmes. Passwords can be applied for specific directories to restrict access to unauthorized users.
Centralized Software Management- One of the greatest benefits of installing a school network is the fact that all of the software can be loaded on one computer (the server). This saves time and energy when installing updates and tracking files.
Electronic Mail- A network that provides the hardware necessary to install an e - mail system. E-mail’s help in personal and professional communication for all school personnel as it enables the spread of general information to the entire school staff. Example, electronic mail on LAN (Local Area Network) enables students to communicate with teachers and peers at their own school when connected to the Internet, it enables users to communicate with others.
Flexible Access- School networks allow students to access their files from computers throughout the school. Some schools provide public access to students to begin an assignment in the computer lab and save then access the file when they are at a cyber cafe or home.
Disadvantages of Installing a School Network
Expensive to Install.
Large campus networks can carry hefty price tags. Cabling, network cards, routers, bridges, firewalls, wireless access points, and software can get expensive, and the installation would certainly require the services of technicians. But, with the ease of setup of home networks, a simple network with internet access can be setup for a small campus in an afternoon.
Requires Administrative Time.
Proper maintenance of a network requires considerable time and expertise. Many schools have installed a network, only to find that they did not budget for the necessary administrative support.
Servers Fail.
Although a network server is no more susceptible to failure than any other computer, when the files server "goes down" the entire network may come to a halt. Good network design practices say that critical network services (provided by servers) should be redundant on the network whenever possible.
Cables May Break.
The Topology chapter presents information about the various configurations of cables. Some of the configurations are designed to minimize the inconvenience of a broken cable; with other configurations, one broken cable can stop the entire network.
Security and compliance.
Network security is expensive. It is also very important. A school network would possibly be subject to more stringent security requirements than a similarly-sized corporate network, because of its likelihood of storing personal and confidential information of network users, the danger of which can be compounded if any network users are minors. A great deal of attention must be paid to network services to ensure all network content is appropriate for the network community it serves.
Explanation:
Advantages and Disadvantages of Computer Networking
Computer network is defined as a set of interconnected autonomous systems that facilitate distributed processing of information. It results in better performance with high speed of processing.
Advantages of Network:
These are main advantages of Computer Networks:
Central Storage of Data –
Files can be stored on a central node (the file server) that can be shared and made available to each and every user in an organization.
Anyone can connect to a computer network –
There is a negligible range of abilities required to connect to a modern computer network. The effortlessness of joining makes it workable for even youthful kids to start exploiting the data.
Faster Problem solving –
Since an extensive procedure is disintegrated into a few littler procedures and each is taken care of by all the associated gadgets, an explicit issue can be settled in lesser time.
Reliability –
Reliability implies backing up of information. Due to some reason equipment crash, and so on, the information gets undermined or inaccessible on one PC, another duplicate of similar information is accessible on another workstation for future use, which prompts smooth working and further handling without interruption.
It is highly flexible –
This innovation is known to be truly adaptable, as it offers clients the chance to investigate everything about fundamental things, for example, programming without influencing their usefulness.
Security through Authorization –
Security and protection of information is additionally settled through system. As just the system clients are approved to get to specific records or applications, no other individual can crack the protection or security of information.
It boosts storage capacity –
Since you will share data, records and assets to other individuals, you need to guarantee all information and substance are legitimately put away in the framework. With this systems administration innovation, you can do the majority of this with no issue, while having all the space you requirement for capacity.
Disadvantages of Network:
These are main disadvantages of Computer Networks:
It lacks robustness –
If a PC system’s principle server separates, the whole framework would end up futile. Also, if it has a bridging device or a central linking server that fails, the entire network would also come to a standstill. To manage these issues, gigantic systems ought to have a ground-breaking PC to fill in as document server to influence setting to up and keeping up the system less demanding.
It lacks independence –
PC organizing includes a procedure that is worked utilizing PCs, so individuals will depend a greater amount of PC work, rather than applying an exertion for their jobs that needs to be done. Beside this, they will be subject to the primary document server, which implies that, in the event that it separates, the framework would end up futile, making clients inactive.
Virus and Malware –
On the off chance that even one PC on a system gets contaminated with an infection, there is a possibility for alternate frameworks to get tainted as well. Infections can spread on a system effectively, in view of the between availability of different gadgets.4. Lack of Independence
Cost of network –
The expense of executing the system including cabling and equipment can be expensive.
PC systems administration will dependably be a quick and advantageous methods for exchanging and sharing data, yet individuals ought to know about its outcomes too.
