Computer network

In today’s world, every organization uses a Computer network to maintain a proper flow of data communication. The Computer network is the lifeline of an organization responsible for regulating data transmission throughout the complete hierarchical structure. These networks are used to share and exchange information which can be a text file, image file, or multimedia file. Computer Networking is a very familiar word among office people. Some time have you got seen below errors in your office computer or personal computer Then you Need to Setup Your Network Properly.   

What is a Computer network?


A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is a connection to the Internet. Other shared resources can include a printer or a file server.

Advantages of the Computer network?.


1) It enhances communication and the availability of information. 
 Networking, especially with full access to the web, allows ways of communication that would simply be impossible before it was developed. Instant messaging can now allow users to talk in real-time and send files to other people wherever they are in the world, which is a huge boon for businesses. Also, it allows access to a vast amount of useful information, including traditional reference materials and timely facts, such as news and current events.

2) It allows for more convenient resource sharing. 
This benefit is very important, particularly for larger companies that really need to produce huge numbers of resources to be shared with all the people. Since the technology involves computer-based work, it is assumed that the resources they wanted to get across would be completely shared by connecting to a computer network that their audience is also using.

3) It makes file sharing easier. 
Computer networking allows easier accessibility for people to share their files, which greatly helps them with saving more time and effort since they could do file sharing more accordingly and effectively.

4) It is highly flexible. 
This technology is known to be very flexible, as it gives users the opportunity to explore everything about essential things, such as software without affecting their functionality. Plus, people will have the accessibility to all the information they need to get and share.

5) It is an inexpensive system. 
Installing networking software on your device would not cost too much, as you are assured that it lasts and can effectively share information with your peers. Also, there is no need to change the software regularly, as mostly it is not required to do so.

6)   It increases cost efficiency. 
With computer networking, you can use a lot of software products available on the market which can just be stored or installed in your system or server and can then be used by various workstations.

7) It boosts storage capacity. 
Since you are going to share information, files, and resources with other people, you have to ensure all data and content are properly stored in the system. With this networking technology, you can do all of this without any hassle, while having all the space you need for storage.

 Disadvantages of the Computer network?.

1)  It lacks independence.
 Computer networking involves a process that is operated using computers, so people will be relying more on computer work, instead of exerting an effort for their tasks at hand. Aside from this, they will be dependent on the main file server, which means that, if it breaks down, the system would become useless, making users idle.

2) It poses security difficulties. 
Because there would be a huge number of people who would be using a computer network to get and share some of their files and resources, a certain user’s security would be always at risk. There might even be illegal activities that would occur, which you need to be careful about and aware of.

3)  It lacks robustness. 
As previously stated, if a computer network’s main server breaks down, the entire system would become useless. Also, if it has a bridging device or a central linking server that fails, the entire network would also come to a standstill. To deal with these problems, huge networks should have a powerful computer to serve as a file server to make setting up and maintaining the network easier.

4) It allows for more presence of computer viruses and malware. 
There would be instances that stored files are corrupt due to computer viruses. Thus, network administrators should conduct regular check-ups on the system, and the stored files at the same time.

5)  Its light policing usage promotes negative acts. 
It has been observed that providing users with internet connectivity has fostered undesirable behavior among them. Considering that the web is a minefield of distractions—online games, humor sites, and even porn sites—workers could be tempted during their work hours. The huge network of machines could also encourage them to engage in illicit practices, such as instant messaging and file sharing, instead of working on work-related matters. While many organizations draw up certain policies on this, they have proven difficult to enforce and even engendered resentment from employees.

6) It requires an efficient handler. For a computer network to work efficiently and optimally,
 it requires high technical skills and know-how of its operations and administration. A person just having basic skills cannot do this job. Take note that the responsibility to handle such a system is high, as allotting permissions and passwords can be daunting. Similarly, network configuration and connection is very tedious and cannot be done by an average technician who does not have advanced knowledge.

7) It requires an expensive set-up.

Though computer networks are said to be an inexpensive system when it is already running, its initial setup cost can still be high depending on the number of computers to be connected. Expensive devices, such as routers, switches, hubs, etc., can add up to the cost. Aside from these, it would also need network interface cards (NICs) for workstations in case they are not built-in.
