yes
It is completely software.
Usually software but some hardware firewall devices are produced.
These are the relationships between CAD and other software and hardware. More CNC machines nowadays can get the drawings straight off cad to machine it.
its a software! you can look in the dictionary if you still want to no more :)

Hardware raid is supported by hardware and usually more stable and achieve better performance. Software raid does not need raid hardware support and can be used on machines without raid options. In the same time stability and performance of software raid is not as high as hardware. Software raid is usually recommended for low budget machines (it's a part of many linux-based system, and it's free of charge) if you are not able to afford a good hardware raid.
Both are of equal importance.
Hardware support is the ability of hardware to use with other hardware or to run an application like software. for more information about hardware, you can check this site http://www.techyv.com/articles/hardware
Both are vital and inseparable to a computer. Without software, the computer cannot do any useful work. Without hardware, the software has nothing to run it.
Yes, the driver is a software that allows computer and a device (e.g. printer) to communicate together and work properly.
well it depends on how much you want to professionalize your classroom, and how much software do you need. Anyway, you wont be spending your money on it, as it aims to get only more expensive by day, since the hardware parts are getting rather cheaper.
