a couple computers in every room
A laptop would be more suitable because it can handle a bigger load than a minicomputer can. Remember networks are computers that work together, and the main computer will organize the computers and process the information from the computers. Everything will go through the main computer. In other words, you will be better off with a laptop rather then a minicomputer.
computer literacy is familiarity with computers and how they work
Not exactly sure what your asking but, an "Ethernet Switch" will connect all the computers together and then any computer can access any computer. If you have 10 computers you would need at least one 10 port Ethernet Switch to connect them all. If you mean one computer "controls" all the computers then you would have to buy a software program for that.

Decrease in computer resources cost.
Increase in the price of computer.
A place that repairs computers.
Install it just as you would to one computer. If it's a download, download it on both computers. If it's a CD-Rom, etc. just download it on Computer A, remove the disc and do the same on Computer B.
Kingston is a brand of RAM rather than a type, and they manufacture nearly any kind of RAM that a computer made in the past decade would need.
I think a better term would be a "computer technician" and not a computer repairer. You need to have an interest in computers, and the way computers work. A course in computer hardware, popular computer applications, would be useful You need to be a person who does not give up when you can't solve a problem and looks to the right people for help.
