Now-a-days router comes in wireless modes using which computers can be connected without any physical cable.

Computer Networks

At huge level, internet works on Client-Server model. Wide Area Network or simply WAN is a system of network that covers a large geographical area across the world. It receives its data in the form of packetswhich are data frames with their destination address added.

The major purpose of such interconnectivity tutorialspoint computer networks to establish tutorialspoint computer networks communication system in order to make the work easier. There are many pornographic sites that can be found, letting your children to use internet which indirectly affects the children healthy mental life.

Before you start proceeding with this tutorial, I’m making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, primary memory and secondary memory etc.

The best-known computer network is the Internet. So it is suitable only tutorialspoint computer networks very small networks that have maximum two to three routers.


For example, Piconet is Bluetooth-enabled Personal Area Network which may contain up to 8 devices connected together in a master-slave fashion.

In this way it is similar to a routerthe only difference being router can transmit data only over networks tutorialspoint computer networks use same protocols.

Such virus attacks may cause your system to crash or your important data may get deleted. A computer tutorialspoint computer networks spanned inside a building and operated under single administrative system is generally termed as Local Area Network LAN.

Data Communication & Computer Network

If you are not well aware tutorialspoint computer networks these concepts then I will suggest to go through our short tutorial on Computer Fundamentals. A network can be as small as tutorialspoint computer networks between your mobile phone and its Bluetooth headphone and as large as the internet itself, covering the whole geographical world.

It uses packet switching technique to receive, store and forward data packets on the network. A gateway can also be configured completely using software.

Let us explore some of these devices tutorialspoint computer networks greater detail. Since they are equipped with very tutorialspoint computer networks speed backbone, WANs use very expensive network equipment. In modern computer systems, it is an internal hardware component. IP Address is a unique set of numbers such as Computers automatically detect USB card and can install the drivers required to support the USB network card automatically.

Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over the network.

Ethernet is a technology that defines protocols tutorialspoint computer networks establishing a LAN. It is the largest network tktorialspoint existence on this planet. However, in such connectivity, some other devices can also be attached such as laser printers, fax machine, etc.

Following are the various modes for entertainment over internet. Before forwarding, the packets are checked for collision and other network errors. PAN has connectivity range up to 10 meters. Computers and other devices are connected to tutorialspoint computer networks router using network cables.

The services of WAN are provided by public government agencies as well as private agencies. Internet is defined as an Information super Highway, to access information over the web.
