I learned a bit about network topologies in middle school. I remember the Star network is where all the computers in the network connect to one hub. It's nice because if one computer goes down it doesn't screw over the whole network like a Bus or Ring network but if the hub fails then everybody is screwed. The Ring and Bus also have another disadvantage which is when you want to make a change to the network like adding another machine it takes down the whole network which is really bad if you need to run 24/7. Mesh is very nice since every computer runs to each other creating redundancy but all that cabling would be expensive and confusing. There are some topologies I didn't know about until now like point-to-point and point-to-multipoint but I'm still reading up on them so I don't have anything to offer on them.
Three day weekend ahead which means I can
play video games read up on Network+ and do some other projects.
