Being so popular an activity, it's imperative that you compress the files destined for another computer. File compression combines a number of different files into one file, and it can also significantly reduce a very large file to a smaller one. As a result, the transmission of a compressed file across the Internet is faster and smoother. Be aware however, that because shareware is not commercial software, you may not experience a full program the way you would if you bought the software out of a box. Shareware may or may not be limited - meaning that some functions may not be available to you until the program is paid for. These limitations are often small and don't interfere with the way its full version operations. The floppy not only stored the program (word processor, spreadsheet, etc.), it also stored the drivers that the program needed to communicate with the computer's hardware. As you can imagine, the cumbersome process of switching from floppy to floppy prompted the birth of the operating system. An operating system is a software program that controls how the computer's hardware (and installed software) works. So costly that the temptation to pirate a little software here and there can be pretty tempting. Co-workers are familiar with this temptation and they're often the ones who "share" purchased software among those who need it. However the same temptation also prompts others to knowingly or unknowingly buy bootleg copies of commercial software or registered shareware. If we're not careful, we could end up replacing almost every hard and soft part of a computer that we own - all in an effort to upgrade! Upgrading in this fashion is not only silly to do so, it's also costly - more costly than simply buying a new computer. But once the decision to buy a computer is set in stone, what can be done with the old one? Here are some examples. Banking is self-serviced through the desktop-clad ATM machine. Gas stations are self-serviced through a menu-clad touch screen kiosk. Most cash registers are Windows XP or Vista machines that send purchase details back to headquarters via the Internet (or a small Intranet). Having your weight, blood pressure, and heart rate measured and recorded is now a digitized process.
