My question is this:
1) What applications or OS do any of you recommend that I will need to know more about in the networking field? (wireshark, Windows Server 2012, etc.)
Also, it doesn't just have to be a networking type app. For example, I am watching tutorials on MS Office, Adobe Acrobat, Shockwave, etc.
I just want to get a better feel for widely used applications and OS. Thank you in advance!
