Data Communications and Networking 2 
(PreLim)

Data Communications and Networking 2(Cisco 2) is all about network routing and switching essentials. In this course you will have a clear understanding in what are routers,and switches are all about and its purpose. Also in this course we’ve prepared for you well suited laboratory exercises for you to gain knowledge and skills in configuring these devices in different scenarios and in different networking environments. In between you will have some tips or pointers for you to make things easier. This course will not just help you to understand topics easier but prepare you in the real life networking environment and help you in passing some Cisco certification exams.For this course,it is essential at least you have a basic background in networking and you need to download Cisco Packet Tracer Student software as your simulation tool for the labs.
