Study of Recent Technologies in computer Network

Abstract

A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected using services available from phone companies, people can send e-mail, share links to the global Internet, or conduct video conferences in real time with other remote users. When a network becomes open sourced it can be managed properly with online collaboration software. As companies rely on applications like electronic mail and database management for core business operations, computer networking becomes increasingly more important. However, in this day and age simply having internet is not enough, you need to be able to get high speeds that all companies from Verizon to Megapathshould be able to provide. On the most fundamental level, a computer network is an interconnected collection of devices that enables you to store, retrieve, and share information. Commonly connected devices include personal computers (PCs), minicomputers, mainframe computers, terminals, workstations, thin clients, printers, fax machines, pagers, and various data-storage devices. Recently, other types of devices have become network connectable, including interactive televisions, videophones, handheld devices, and navigational and environmental control systems. Eventually, networked devices everywhere will provide two-way access to a vast array of resources on a global computer network through the largest network of all, the Internet. In today’s business world a computer network is more than a collection of interconnected devices. For many businesses the computer network is the resource that enables them to gather, analyze, organize, and disseminate information that is essential to their profitability. The rise of intranets and extranets—business networks based on Internet technology—is an indication of the critical importance of computer networking to businesses. Intranets, extranets, and the Internet will be treated in more detail in a later section. For now, it is enough to understand that most businesses have installed intranets to collect, manage, and disseminate information more quickly and easily than ever before. They established intranets simply to remain competitive; now, the momentum continues, and extending the company network to the Internet is the next technological transformation of the traditional business.
