The fact that computers can be connected is referred to as connectivity. Connectivity greatly enhances the power of your computer, bringing immense stores of information to your fingertips and making it possible for you to interact with people around the world. Connectivity is the prerequisite for developing the field of telemedicine. Computers and other hardware devices that are connected form what is called a network and gives you access to all the information on the computers and networks to which you are connected.
Networks come in all sizes, from small local area networks (LANs), which span one room, to wide area networks (WANs), which may span a state, nation, or even the globe, like the Internet and World Wide Web. Networks can be private or connected via telephone lines, making them telecommunications networks.
