Chapter 9 Communications and Networks

Computer communications describes a process in which two or more computers or devices transfer data, instructions, and information. For successful communications you must need a sending device, a communications channel, and a receiving device. A network is a collection of computers and devices connected together via communications and transmission data. A communications device is any type of hardware capable of transmitting data, instructions,  and information between a sending device and a receiving device. A router is a communications device that connects multiple computers or other routers together and transmits data to its correct destination on the network. For example, when I got WiFi at home we had to get a wireless router so we could have wireless throughout the house and more than one device could connect to the Internet.
