Networking

A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.

Network computer devices that originate, route and terminate the data are called network nodes.[1] Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.

DEMAND

If 100 candidates are hired by a tech firm, almost 60-65 will be for the Networking division, say experts. Firms like HCL, Wipro as well as Infosys are big recruiters for IMS. And with services like Aadhaar becoming prevalent, demand has also risen in the public sector for professionals who can maintain networks that support schemes like Aadhaar.

“In the last four to five years the demand for networking professionals has increased tremendously,” says Harsh S Bharwani, vice president (international business) at training institute Jetking. The good news is that not just BEs and BTechs but also those with other degrees or backgrounds can scout jobs in Networking post relevant certification courses.
