Having an idea of what you want in a computer and what kind of computer that you want, your only task left is to select the place in which you want to buy it. There are a number of places available including computer store outlets, online stores, auction sites, used computer stores, or your friendly neighborhood yard sale. And although this program may install just fine on a Windows 98 machine, it will generate a multitude of errors once its started. Insufficient memory will cause errors as well. That's why software programs include minimum memory requirements. A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. In this case, a person (such as yourself) operated a computer without even knowing it! Can an absolute newbie sit down at a computer without knowing how to use one? Assuming that a computer is set up to operate on touch command - the answer is again, yes!

By using simple commands, you can program your computer to perform mathematical tasks, fill out web forms, compose an email message and send it off, or any number of other things. You could end up typing a command as wide as your computer screen or worse, long enough that the entire command would have to wrap onto the next line! Now imagine having to type these long commands every time that you wanted to start a program. Yikes! That's one of the reasons why batch files became so popular.
