Wireless network avoid the cable cost

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes.

Wireless networking is a method by which homes,telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.

Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks.

Different types of computers

The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windows operating system. PCs were first known as microcomputers because they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.

                                     The iMac is an all-in-one desktop computer from Apple.

   There are a lot of terms used to describe computers. Most of these words imply the size, expected use    capability of the computer. While the term computer can apply to virtually any device that has             a microprocessor in it, most people think of a computer as a device that receives input from the user througha mouse or keyboard, processes it in some fashion and displays the result on a screen.
