write five advantages and disadvantages of computer network.
Answers
Answer:
ADVANTAGES
Sharing devices such as printers saves money.
Site (software) licences are likely to be cheaper than buying several standalone licences.
Files can easily be shared between users.
Network users can communicate by email and instant messenger.
Security is good - users cannot see other users' files unlike on stand-alone machines.
Data is easy to backup as all the data is stored on the file server.
DISADVANTAGES
Purchasing the network cabling and file servers can be expensive.
Managing a large network is complicated, requires training and a network manager usually needs to be employed.
If the file server breaks down the files on the file server become inaccessible.
Email might still work if it is on a separate server. The computers can still be used but are isolated.
Viruses can spread to other computers throughout a computer network.
There is a danger of hacking, particularly with wide area networks. Security procedures are needed to prevent such abuse, eg a firewall.

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.
