In practice, a network is comprised of a number of different computer systems connected by physical and/or wireless connections. The scale can range from a single PC sharing out basic peripherals to massive data centers located around the World, to the Internet itself. Regardless of scope, all networks allow computers and/or individuals to share information and resources.

Computer networks serve a number of purposes, some of which include:
Communications such as email, instant messaging, chat rooms, etc.
Shared hardware such as printers and input devices
Shared data and information through the use of shared storage devices
Shared software, which is achieved by running applications on remote computers

The media can be classified by type of connection as guided or directed, where they are: the coaxial cable, the twisted pair cable (UTP / STP) and the optical fiber; and not guided, where are radio waves (Wi-Fi and Bluetooth), infrared and microwave. The guided media are those made up of cables, while the non-guided media are wireless.]]> 2019-06-25 03:30:54 UTC https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369044549 Purpose alejodiaz_1706 https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369044611 1-   share resources and information remotely

The most usual option, however, to increase the coverage radius and to avoid the installation of structured wiring, is usually the purchase of a router and the installation of a wireless local area network]]> 2019-06-25 03:38:21 UTC https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369045164 Wireless personal area network (WPAN): alejodiaz_1706 https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369045241 For wireless network of a few meters]]> 2019-06-25 03:39:14 UTC https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369045241 Campus area network (CAN): alejodiaz_1706 https://padlet.com/alejodiaz_1706/vjd5cljbfjqd/wish/369045271 What happens if the coverage area should be greater than 1000 square meters? And I do not say it only for the universities; the facilities of the technology parks, fairgrounds and commercial buildings can perfectly overcome this surface.
We have CAN networks. There would be several local area networks installed in specific areas, but in turn all of them would be interconnected, so that data can be exchanged with each other quickly, or there may be an Internet connection throughout the campus.
