What is Networking?

CCNA Courses : To communicate is one of the basic skill that mankind have been practicing since the origin. The only thing that kept changing was the medium used to communicate. We have evolved a lot in ages and now we can effectively communicate with people from anywhere in the world and even outside the world. There are different advanced forms to do it but when you burn them all to ground the ultimate idea is to exchange information between a sender and a receiver by connecting them via a medium that depends on area that separates them and mode of communication they prefer. It was simply classified as LAN (Local Area Network), WAN (Wide Area Network) and MAN (Metropolitan Area Network) decades ago. But we now have a more classified system based on the enormous advancement in technology.

Why Join this Program?

Learn all there is to know about IT networking, network administration and network certification with Pluralsight. Our networking authors draw on real-world experience to help further your knowledge. From CCNA certification courses to the fundamentals of infrastructure networking, we have the course you need.

Who is this program for?

Irrespective of the medium, to maintain privacy and security there are various protocols being defined and followed by countries with law and order. Networking is the study and implementation of all this. Study of Networking includes the following Skills:

Fundamentals of Networking
Network Access
IP Connectivity
IP Services
Security Fundamentals
Routing & Switching
Cyber Security & Forensic

CISCO being a pioneer in this sector, certify candidates as professionals if they have skills to provide services, installation, operation and troubleshooting in networking products and systems.
