A program that needs 14MB of memory will generate errors on a computer that only has 4MB of memory if it runs at all. The same goes for disk space, monitor color depth and resolution. In these situations, problems occur the moment that a piece of software attempts to access the things (hardware, memory, space, resolution, etc. Connected to the network, each computer can send files back and forth, open programs on a remote computer, play the sound files and videos located on another computer, and share a single Internet account to browse the web, download files, or chat with someone in an entirely different country. If a single printer is available on only one computer in the network, every connected PC can send documents to it and print them out. Hopefully by the time you finish reading this article, you'll understand the lesson that we were trying to teach our client: "What comes out of the box is really just a starter kit." The typical computer package comes with a CPU unit, keyboard, mouse, and speaker set. That may be just fine for some, but most people require more than that especially in today's "connected" society. Shareware is all over the Internet and it's really hard not to bump into it. The most popular places to find shareware is within thousands of download libraries, however the companies (and even independent programmers behind shareware) are increasingly offering shareware from their own websites. A simple Google or Yahoo search for a particular type of program will yield all sorts of results that point you toward items that you can try before you buy. Attempting to do the same with a bulky desktop computer or laptop is to cumbersome. Even some of the smallest peripherals (digicams, digital cameras, etc.) don't give us the same opportunities that smart phones do. Being able to carry around a device for communication, creation, recording, and editing simply compliments the need for today's generation to do more and then do it, faster! Earlier computers didn't have an operating system and if you have experience with the computers of the early eighties, you'll remember that most to them didn't even have a hard drive! These old computers booted an MS-DOS type operating system from drivers stored onto a floppy disk, and in order to use a program, users would remove the boot floppy and then insert a new floppy that contained the program.
