So what are all these "nobody" processes referring too?

nobody is the user assigned to the Web Server by default under some Operating Systems. As you can see from your top command output, the user is running nothing but httpd (the web-server).

Basically the nobody user exists because a web server always wants everyone, to be someone. Thus making it more secure. However there are some security issues with having the user take its default name (nobody) but if your running the latest version of your OS then it should be fine!

It tends to be ran under the user nobody because that user has very few permissions. It also doesn't have a password thus making logging in as that user, next to impossible. There is nothing much to worry about here. Its just Apache going about its daily business :P

Alright sounds good, thank you!
