Overview

Network certifications are credentials you can earn to demonstrate your ability to work with networks in the information technology (IT) field. They can be vendor-specific—focusing on the technology from one company, like Cisco or Microsoft—or vendor-neutral, meaning the things you learn should be applicable across different networking technologies.
