It is essential to transfer stored information across various geographical locations to process and complete a range of business activities. Computer networks provide a fast, dependable and accurate way of doing this in favor of a business domain.
Purpose of computer networks
From a user's point of view, there are many advantages of having a computer network. The major purpose of a computer network is to share hardware and software resources. In sharing hardware, you can access a printer connected to a remote PC, and you can allow one of your colleagues to use your own PC's CD-ROM from his computer.
Whenever you share software resources, you execute a software application in a remote server. The server will do all the processing while your computer does only the input and output, without using much processing power. This is especially beneficial when the client computers are less capable machines, whereas high-end servers are available to get the job done.
From a network administrator's perspective, a computer makes management of the computers easy and effortless. Regular tasks like maintenance, backup and new software installation will be a tedious task without a computer network. With a little help from a computer network, additional duties such as assistance, security allocation and monitoring becomes a piece of cake.
To form an operational computer network you need to have some hardware devices. One of the major components is the Network Interface. The network interface may be an Ethernet (a type of network) adaptor, a modem, a wireless network card or your ADSL modem. This device is essential for contact with the other end of the communication.
Always, the connection is established over a communication media. Wired or bounded communication media are one type that contains cable media such as Twisted-Pair cable, Co-axial or Optical Fibers. Unbounded media types use wireless technologies, for instance Microwave, Radio waves and Infrared waves.
Some advance networks need additional communication equipment, such as Switches, Gateways, firewalls, and Routers. These devices increase the reliability of the communication and makes it smooth and error-free. All networks need not have all these hardware, but for certain types of networks, some of them stand compulsory.
Many networking standards provide ways and means to follow when investing for a new computer network. Hardware device capabilities, protocols and wiring regulations are some of the few points to consider. Selecting the correct networking standard depends upon the requisite of the designated network. Thorough analysis of the business requirement is necessary before choosing a standard to investigate the suitable type of network that fit the usage demands. Deploying a computer network should be a well-planned activity, just like developing a new custom software package.
Computer networking is a vast subject area that can be divided into different sensible subcategories. Accurate scrutiny of necessity, research and deployment of a computer network will enhance your business into a complete new dimension.
