The computer network is a system that connects a computer device with other devices (eg, printers), through the medium of communication, so that data and information can be sent. Bandwidth refers to the transmission capacity of a network; (bits / second). Broadband refers to the transmission capacity of the network, which has a range from 1 million bits per second (megabits / s) up to 20 megabits / s, using the fiber.
Here are the various types of computer networks:
- Personal Area Network (PAN), is a network that has a short range, typically only cover a few meters and is used for communication between devices that are close together.
- Local Area Network (LAN), connecting two or more devices, usually in the same building, so that each device in the network communicate with each other. Most of the currently used LAN, using Ethernet (Picture Below). Ethernet in Picture Below consists of four (4) computers, a server and a printer in which the whole is connected with a cable.
