Networking Computer Systems :: Computer Networks

Networking Computer Systems A network is a group of two or more computer systems sharing services and interacting in some manner. In most cases, this interaction is accomplished through a shared communication link, with the shared components being data. Put simply, a network is a collection of machines that have been linked both physically and through software components to soothe communication and the sharing of information. To make the communications between two or more computers work, several things need to be in place. First, some type of physical connection mechanism has to exist between the computers involved. Normally, this mechanism is a wire or cable of some kind or a transceiver that can both transmit and receive information attached to or built into your computer. The idea of computer networking is new to some people and almost always seen as a highly technical and rapidly evolving process. Every day, computer professionals are called upon by their employers to evaluate, judge, and implement t he technologies necessary for the rapid communication of dissimilar groups in order to enhance productivity or lessen complexity within the organization's processes. Most see the task as a formidable one, and many feel they are not qualified or fully prepared to drive the creation of a Local Area Network (LAN) or Wide Area Network (WAN). The type of network you can create is often determined by the network operating system you use. Like a regular operating system for your PC, a network operating system coordinates how all the individual software application on a network work and how the network interacts with the hardware attached to it. Sharing data is made much easier when a network is involved. People are more productive because several people enter data at the same time and can also evaluate and process the shared data. The effective use of networks can turn a company into an agile, powerful, and creative organization, giving it a long-term competitive advantage. Networks can be used to share hardware, programs, and databases across the organization. They can transmit and receive information to improve organizational effectiveness and efficiency. They enable geographically separated workgroups to share documents and opinions, which fosters teamwork, innovative ideas, and new business strategies (Stair, Reynolds 269). Getting computers connected and speaking the same language may be somewhat interesting for some people, but it’s really just a necessary evil to get to the good stuff.
