Relevance of Computer Networks

Before reading this article, I advise you to read an Introduction to Computer Networking.

Computer networking is important because it provides businesses and corporations with a more clear and reliable source of connection between one another. Networking all the computers in the office gives all employees access to the same materials, making it easier to provide information to company employees, as well as customers. This is especially true in customer relations and customer service positions. Computer networking eliminates the need for the customer to keep track of their issues, and instead, these issues can be passed along if, and when needed.
Hence Despite its cost and implementation, networks benefit organizations by helping it save money in the following ways:

1. First network helps to consolidate storage. These storage are used to keep information (i.e. customer information, billing, track orders, employee payroll, etc...) that an organization needs to thrive.
2. Allows the ease of sharing peripheral devices like printers. By having networks, this allows for the company to connect multiple computers to one printer. This saves the company from having to purchase a printer for each computer. Though it may sound convenient for each computer to have its own printer, it would be a waste of capital.
3. It will increase internal and external communications. Communications will help a company succeed and thrive among its clients and employees.
4. Increase productivity and collaboration within the organization. The ability to email, call, share documents, and video conference increases work productivity for employees. Information, orders, assignments, and ideas are able to travel fast.

There is no denying that every organization needs computer network today. Without it, a business is doomed to fail.
