Cisco

If you want to get an IT job you have to know a lot of things and Cisco is a big name nowadays. There is hardware with their name as well.
Online, cisco is a place where you can learn networking, things about software and hardware. I took some courses there and I'm pround to have their diploma on my CV. Every big company knows about cisco. They lessons are good and the community is always here to help you. You will need to find a place to enroll, usually a school or something but that's not a big deal. Their courses are FREE and worth it. Trust me.
I'm a cisco member for more thank 3 years and I highly recommend it for everyone.
