New job, need some basic network knowledge.

Hi,

I just got a new job and I'd like to get some basic networking knowledge. I don't need to be a pro, but I'd really like to understand the basics of everything, routers, switches, DHCP, subnet masks, all of that is really vague for me.

I was looking at the basic Cisco networking course on Coursera https://www.coursera.org/specializations/networking-basics

Would anyone recommend it, or recommend other resources?

Thanks
