What Is Computer Networking?

  • Step 1:
    A computer network consists of several computers that are connected to one another using devices that allow them to communicate. Computer networks may be connected using network cables called Cat5 cables and network cards. Your network may also be wireless and connected using wireless routers. If your computer network is wireless, it would not require that they be connected using hardware. When the computers are connected via a computer network they are able to transmit files from one computer to another. These computers are also able to connect to the internet using one connection.

What Are the Types of Computer Networks?

  • Step 1:
    There are several types of networks, such as a LAN(local area network), a CAN(Campus area network), MAN(metropolitan area network) and a VPN(virtual private network. A LAN is a network that is made up of computers that cover a small areas, such as a home network or a small office. The network can be connected using a router. A CAN network is a computer network that is made up of several LANS. This type of network is used on college campuses. A MAN computer network is made up of several CAN computer networks. This type of network would use routers and hubs to connect it. A VPN network does not use wires or cable to connect it. This type of connection is also secure and is mainly used in larger environments.

How Are omputer Networks Connected?

  • Step 1:
    Computer networks are connected using network interface cards(NIC), hubs, routers and bridges or switches. NIC cards are devices that are installed inside of a PC, or they may be connected to the USB port on the computer. They allow the computer to communicate with other computers. A hub contains several ports that allow several computers to connect to it and act as one. A router is a device that allows several computers to connect to a secure network. Bridges connects several networks by using ports and IP addresses. Switches filter information between the network's ports based on the MAC addresses.
