The network is the single greatest vehicle for knowledge, understanding, and human advancement that the world has ever known. Now more than ever, the world relies on high-performance networks. And now more than ever, the world needs network innovation to unleash our full potential.

The network plays a central role in addressing the critical challenges we face as a global community. Consider the healthcare industry, where the network is the foundation for new models of mobile affordable care for underserved communities. At its core, the network has become a platform—one that transforms how we interact with our government institutions, conduct business on a daily basis, and connect with our family and friends.

Before considering network requirements, the machines and software, which are to be networked now or in the future, must be identified. The purpose of this step is to identify which software applications the network operating system and hardware must support. Exclude software or machines that will be discarded for other reasons from further networking.

The first step is to establish the aims of network implementations like :- Implementation of administrative and financial database, staff access to company records, email for staff & staff scheduling, automation of letter, report or specification for writing.

General information automation (including library, plans, graphics and images), Learning or training aids (interactive software), Printer sharing, File transfer & for Internet access (graphical, text, news, etc). Computer skills training rooms (word processing, publishing, CADD, spreadsheets, databases). Access to centralized information sources (e.g. CD-ROM stacks). Automate software updates & Centralize application software.
