Sure, the programming behind such technology is extensive and advanced, but to the end user, it makes computer use less intimidating and plain easy. Of course when we talk about operating a computer, we envision more involvement than speaking on the phone or touching things on a screen. The above illustrations were just a couple of examples of how far computer technology has grown, and how far we've pushed "user-friendliness" to its limit. So while Windows' Add/Remove Programs can remove an entire program, you'll need to get rid of those pesky little things with a more advance file cleaner like CleanSweep for example. CleanSweep is a unique program that will specifically seek out files that are no longer associated with a program, and then ask if you want to delete them. 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. Not just a bunch of preference settings, display properties help individuals who have to deal with visual problems. Accessibility Options. Speaking of visual problems, another setting that's useful is accessibility options. This setting allows people with disabilities to use a computer that accommodates vision and hearing problems. 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. NOTE: Some of these tools include kid-specific web browsers that will visit pre-approved websites. Others include browser plug-ins that won't allow access to online areas that contain forbidden keywords. Another step requires teaching your children to never ever volunteer personal information. Under no circumstances, should children give their personal names, home addresses, phone numbers, or school information to anyone over the Internet regardless of the situation.
