Since the assignment is really to tell about all you've learned, I'm gonna start off with what I learned about operating systems in general. I didn't realize that they pretty much ran the entire computer, including starting up and shutting down, managing programs, file management, and even as basic as connecting to the Internet. Basically, an operating system is the system that lays the foundation for almost everything you could possibly need to accomplish on a computer. Something that I've learned in class is that most phones in today's era are really nothing less than miniature, hand-held computers, so even your cellular device has an operating system and couldn't perform many basic tasks that we expect from our phones without an OS. Another thing I didn't consider is that operating systems are usually designed to specifically run on one certain type of computer, but this fact isn't difficult to derive once you know the name of an OS. For example, Mac OS X runs only on Macbooks, and Blackberry (you guessed it) runs on the Blackberry cellular phones.
Upon investigation, I found only two operating systems that I personally use; the first was fairly obvious to me, for I did know that Windows 7 runs on my Lenovo Thinkpad. I did a little research and learned that the first version of Windows came to existence in the mid 1980's, but since then Microsoft has almost constantly been configuring new versions and brought us to what we know now: Windows 7. What I didn't know about Windows 7?
1) That even though Windows 7 is the newest version of Windows, there are still four editions of Windows 7. Windows 7 Starter is designed for small computers like netbooks or notebooks; it is a very basic edition that is typically installed on a computer upon purchase and not sold in stores. Windows 7 Home Premium, which is capable of all that Windows 7 Starter can perform, merely has the addition of Windows Aero which provides additional visual performance and navigation. Windows 7 Ultimate is yet another step up, again consisting of all Windows 7 Home Premium capabilities, only with additional elements to ensure file security. Windows 7 Professional is more adapted for small businesses so that users can take advantage of advantaged backup features, easily share documents and search for files, and etc.
2) Shortcuts enabled by the Windows key when used in unity with another key. I know this must seem like ridiculously juvenile information to just now be learning, but I am. I learned this on Wikipedia's page "Features new to Windows 7" and had some fun messing around with the features that the Windows key (which I had previously ignored) enabled.
3) The hibernation file size is configurable in Windows 7. I found this kind of interesting because I had just recently learned from my book the difference between hibernation and sleep mode. In sleep mode, any open documents or programs are saved to the RAM, where in hibernation, these documents or programs are saved to a hard disk. In Windows 7, the hibernation file size can be set from 50% to 100% of the complete physical memory. This enables the hibernation file to become compressed and take up much less space. The default size on Windows 7 is 75%, but you can learn more about how to manage this at Reducing the Disk Footprint for Windows 7 Hibernation.
4) Third-party software is no longer required in order to burn image discs. In previous versions of Windows, this was necessary and a sure inconvenience for the majority of Windows users. But with the new Windows 7, a user need only right-click an image file and select "Burn disc image" from the drop-down menu to write the image to a disc. This makes backing up images to a hard copy so much easier, and I know I certainly appreciate this because I often copy my photography to discs for various reasons. This newer feature is something I definitely benefit from.1) That even though Windows 7 is the newest version of Windows, there are still four editions of Windows 7.

5) Equipped with advanced custom features for your desktop. This was something else that I didn't know about at all until I actually started digging around for Windows 7 features on the web. I soon ventured into my control panel and began customizing my desktop; I was able to change the task bar color from slate grey to leaf green and select a variety of pictures to shuffle on my desktop background, something I was probably a little more excited about than I should have been.
The second OS that I use in my daily life was a little more difficult to put my finger on; I have a Nokia E5 smartphone, though I don't use the smartphone aspect of it. I'd rather not pay to have the Internet or picture messaging, so I use it only for text and calls. Thus, I was not under the impression that my phone even had an OS, until I realized (as aforementioned) that every computer, no matter what size or advancement, uses an OS to operate at all. So I looked it up, and turns out this little phone that I use everyday uses an operating system called Symbian 9.3.
1) Only recently did Nokia broaden it's horizons beyond Symbian. Nokia, along with several other software corporations, including Symbian Ltd., created Symbian OS. In December of 2008, Nokia bought Symbian Ltd., and used only Symbian as their mobile operating software. However, in February of this year, Nokia announced its partnership with Windows and their intentions to begin using Windows Phone 7 for their smartphones.
2) The version of Symbian on my phone is not the newest version of Symbian. After doing quite a bit of digging around, I discovered that Symbian is currently on it's 6th version. There have been Symbian^1, Symbian^2, Symbian^3, Symbian^4, Symbian Anne, and finally Symbian Belle. My phone has Symbian 9.3, which I found to be Symbian ^3, so it's a relatively old version but I find it to work well for my demands.
Sadly, this is really all I could find on Symbian despite my struggles to dig around on the web. It isn't the required five, but I did a lot of searching and couldn't find much else since Symbian is becoming a thing of past due to Android, Apple, and Windows. I don't use my phone for most of what my generation does, therefore I believe I have learned all that I'm really going to about this certain software, especially since it is an old version.
I must admit, though, that I learned more than I thought I would through this project, and I had some fun with it. I even got a snazzy new desktop theme. (Note: I had no idea how to take a snapshot of anything on my computer before I did the investigation of Windows 7.)
