What are two different ways to upgrade a computer?

People usually upgrade their computers by either buying hardware (new parts) or software (new programs). Different people will tell you different ways to upgrade your computer. If you want to upgrade your computer for office work, you may just need a newer operating system (ex Windows Vista). If you want to upgrade your computer for gaming or running performance programs, then you may need to upgrade your video card, RAM modules, and hardrive space. You can either install these components yourself, or pay to have an official worker from a store come do it for you.
