Networking or Computer Networking is a field of computer science that deals with sharing the resources amongst the computers located on the network nodes. These connected computers use common communication protocols over the digital interconnections to interact with the other devices that are connected over the network. Telecommunication network technology interconnects the devices over the digital network. The connections are based on physically wired, optical, and wireless radio-frequency methods that may be fashioned in a variety of network topologies.
The nodes of a wireless network van include computers, servers, networking hardware, and any other specialized and special-purpose hosts. Each of the hosts are identified by their IP addresses and may be assigned with domain names. Hostnames are provided to identify the labels of the nodes. They are not usually changed after it is once assigned, but it may anyway happen in rare cases. The network addresses provide a means to locate and identify the nodes by communicating protocols such as Internet Protocols.
Networks or Computer Networks can be classified based on many criteria, including the transmission medium that are used to carry signals, bandwidth, communication protocols to organize network traffic, the network size, the topology, traffic control mechanism, and organizational intent.
The computer network supports applications and services, like the privilege to access the world wide web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and messaging applications that aids in messaging instantly.
The Free Networking courses offered by Great Learning will help you have a good understanding of what networking is, how it works, protocols used to maintain the nodes connected in the network, and other operations. At the end of this course, you will be able to understand the complete network operations, share resources between the devices connected over the network, and also be able to work proficiently with it. You will also earn a certificate for the course after the successful completion. Happy Learning!
