Today it's really not safe to open files from anyone (without scanning the files) because that's how viruses get spread - through files - even by mistake. So even though your co-worker may have emailed a funny video, it's no more safe to open than a video downloaded from a complete stranger. Be safe and scan each and every file you download from the Internet or receive through email regardless of where it came from. This is because the computer is a mere platform - a blank canvas, if you will - waiting for you to direct its operation or paint the picture of the perfect machine. All this is possible from making just a few changes in your computer's current configuration. Your computer's main configurations are housed in Windows Control Panel. You might have heard of some of these languages in the past such as Visual Basic, C++, or Fortran. There are hundreds of other programming language and neither one is better than the other. Most of them are capable of performing the same tasks and achieving the same goals. A programmer chooses one language by a simple preference. To illustrate the importance of accessorizing, we like to use the "plain dough" analogy. Let's say that a brand new computer is a batch of plain dough - waiting to be flavored and baked into something useful. If we want to use this dough to make a delicious batch of chocolate chip cookies, we would need to "accessorize" this dough with chocolate chips and a little brown sugar. Yes, you've not only heard of them, you've probably seen them as well. Packed with Internet access, email capabilities, address books, and a whole lot more, cell phones have come a long way since their first debut. But be careful not to confuse these newest toys with sandbox devices. Sandbox devices are tools that come pre-loaded with things like calendars, calculators, and a notepad. The quality of today's freeware and open source software created a strong rift among the commercial community and it's literally driving the competition bananas! So much so, that even some well known software development corporations have joined the cause and built a few freeware open source products of their own!
