Networks
A Network is a group of devices that are connected in such a manner that they can share information and resources with each other. To create a Network we must have a number of basic components such as NETWORK DEVICES.

What is a computer network?
A computer network is a collection of computer and network equipment connected via communication channels into a single system. To create a computer network, we need the following components:
- Computers that can connect to the network (for example, via the network card that every modern PC has).
- Transmission medium or communication channels (cable, satellite, telephone, fiber-optic and radio channels).
- Network equipment (such as a switch or router).
- Network software (usually included in the operating system or left with the network hardware).
As a rule, computer networks are classified according to two criteria: general networks (user) and special networks (professional).

- What Is a Wireless Network?
A wireless local-area network (LAN) uses radio waves to connect devices such as laptops and mobile phones to the Internet and to your business network and its applications. - Wireless NetworkA wireless network refers to a computer network that makes use of Radio Frequency (RF) connections between nodes in the network. Wireless networks are a popular solution for homes, businesses, and telecommunications networks.
Wireless communication technology is a modern alternative to traditional wired networking. It is a network set up by using radio signal frequency to communicate among computers and other network devices.
- How mobile networks work
Mobile phones work by sending and receiving low power radio signals, much like a 2 way radio system. The signals are sent to and received from antennas that are attached to radio transmitters and receivers, commonly referred to as mobile phone base stations.
This video is explaining how mobile phones work.
