If you only intend to run basic tasks - browsing the web, sending emails, running office-type software like Microsoft Word - then the good news is that most computers, even at the budget end of the market, will be able to cope with your requirements. You will want to consider how much RAM (memory) a computer has, what sort of monitor is large enough for you, and what does the computer come with, or what will you have to buy separately, such as mouse, keyboard, speakers, graphics cards, etc.

The operating system (OS) for a computer is the software that runs the programs. The two most common in the U.S. are Microsoft (Windows) and Mac (Apple). You will have to decide which system is best for you. As a general rule, you will have more computers to choose from in a wider price range if you choose something running Windows. There are only five machines from Apple at this point, and they tend to be more expensive.
