Disadvantages of computer networks :

Computer networks are very helpful when it comes to sharing resources and saving time and money but this technology has some disadvantages too. The most common disadvantages of computer networks are as follows :

1. Expensive: The first and foremost disadvantage of computer networks is that they are expensive to purchase and maintain. The cabling and installation of a large-sized computer network are very costly.

2. Data Security: Special security measures are needed to stop users from using programs and data that they shouldn’t have access to. The proper permissions must be issued to various users according to their nature of work. The proper password validation check must be applied for the authorization and authentication of the user.

3. Manager dependence: The complex networks require a network manager to keep it running. The major problem with networks is that their efficiency is very dependent on the skill of the network manager. A badly managed network may operate less efficiently than non-networked computers. Also, a badly run network may allow external users into it with little protection against them causing damage.

4. Vulnerable to hackers and viruses: Computer networks are very vulnerable to hackers and viruses. For example, if the network is poorly implemented, improper communication may take place. This may lead to the situation in which the private or important mails can be seen by other users or hackers and this may result in loss of privacy or corrupt information system. Secondly, the virus on one system in a network can affect the whole computer network and could prove fatal for the organization.

5. Social problems: Computer networks pose social problems when people post offensive views about sensitive issues like religion, sex, and politics. The newsgroup or bulletin boards allow people«to exchange messages freely on the network. This could lead to a problem because” they are not restricted to post materials on any subject including deeply offensive views regarding religion, caste or creed, etc.
