In many countries worldwide businesses and educational institutions make up a large percentage of society. These places need a way of being able to share information and to communicate within the business or school. They also need to be able to share business plans or other information with outside organizations. Computers were originally developed for individual use only. The importance of sharing data forced manufacturers to create techniques for connecting computers and this was the beginning of computer networks. Soon the importance of networks was realized in business organizations and today almost every organization in the world has its own computer network. Educational institutions are also following suit because networking provides a method for effective management and can also help in improving the knowledge of students. Computer networks are becoming the main source of operation and communication for businesses and educational institutions.

They also troubleshoot problems reported by the users and by automated network monitoring systems and make recommendations for future system upgrades. Many of these workers are also responsible for maintaining network and system security (Bureau of labor, 2009)
Without the internet businesses and educational institutions wouldn’t be able to function or operate as well as they do now and the amount of business they conduct would not be nearly as great. Computer networking makes everything easier and more cost effective for everyone. The internet and computer networking just may be the most effective tools in the everyday world.
