By the end of this lab you'll have a Linux machine with a graphical inerface set up. You will use this for the rest of the course.
Virtualization
Normally all the software on your computer will ask the operating system kernel to do things, and the operating system will pass on those requests to the hardware. The kernel has exclusive control of the hardware. That's why you can only have one operating system running at one time.
If you have more than one operating system installed on your computer (e.g. Windows and Linux): you'll have to choose which one you want to use when you boot your computer.
That's fine for workstations: you own your computer, you use it when you want to, and noone else gets to touch it. When your computer gets old enough to be annoying: you look to upgrade it or buy a new one. For servers that's very wasteful. A computer, whether it's used or not:
- Costs money to buy, and it loses its value just because time passes. Computer technology becomes obsolete in just a few years.
