The most obvious benefit of computer networking is that you can store virtually any kind of information at, and retrieve it from, a central location on the network as well as access it from any connected computer. You can store, retrieve, and modify textual information such as letters and contracts, audio information such as voice messages, and visual images such as facsimiles, photographs, medical x-rays, and even video segments. Computer networking enables people to share information and ideas easily, so they can work more efficiently and productively.
Networks also improve commercial activities such as purchasing, selling, and customer service.
Networks are making traditional business processes more efficient, more manageable, and less expensive. By networking your business computers you can reduce the amount of money you spend on hardware by sharing components and peripherals while also reducing the amount of time you spend managing your computer system. A properly designed network can result in both lower equipment costs and increased productivity. Suppose that you had a number of unconnected computers. Employees using these computers would not be able to print unless you purchased a printer for each computer or unless users manually transferred files to computers with printers.
