A network is a collection of computers and devices connected to each other. The network allows computers to communicate with each other and share resources and information. There are two different kind of networking wired and wireless networking, each one has a unique purpose designed specifically depending on what your goals are.

Wired Networks Ethernet and wireless networks each have advantages and disadvantages; depending on your needs, one may serve you better than the other. Wired networks provide users with plenty of security and the ability to move lots of data very quickly. Wired networks are typically faster than wireless networks, and they can be very affordable. However, the cost of Ethernet cable can add up—the more computers on your network and the farther apart they are, the more expensive your network will be. In addition, unless you’re building a new house and installing Ethernet cable in the walls, you’ll be able to see the cables running from place to place around your home, and wires can greatly limit your mobility. A laptop owner, for example, won’t be able to move around easily if his computer is tethered to the wall.
 
Wireless Networks If you’ve been in an airport, coffee shop, library or hotel recently, chances are you’ve been right in the middle of a wireless network. Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at home, and some cities are trying to use the technology to provide free or low-cost Internet access to residents. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires.
