There are three "big" OS on the market today: Windows, Mac OS and Linux. However, Linux has a tiny fraction of the market in comparison to the others, even though devotees will corenr you for hours to tell you how superior the system is. If it's so great, why are so few people using it? I think it comes down to a few issues: ignorance, convenience and public perception.
Ignorance: As a free OS, Linux certainly isn't making money selling systems. And if it's not making money, it certainly doesn't have a lot of money to spend on advertising. I don't read computer magazines, so there may very well be Linux ads that I'm not aware of, but I doubt it. The main way people hear about Linux is through word of mouth, and that usually means one computer geek talking to another. It's hard to imagine word of mouth managing to trickle down to someone like my elderly aunt who can barely figure out how to connect to the Internet. She is not and never will be a Linux user.
Convenience: Most people hope that when they make a major purchase, they will not need to put in additional efforts afterward. I know that I would not buy a car if the motor was not installed yet, even if the price included a perfectly good (or even superior) motor. For me, when I decide to spend the money on a car, I want it running right away. Many people feel the same way about computers, which is why companies like Dell can thrive. They offer a complete package: a computer with an OS, monitor, keyboard, mouse, printer, etc. No shopping for peripherals, no deciding between numerous options. This is why Windows is the most-used OS. It is the standard OS on all PCs. It comes already on the machine, and the new owners don't have to worry about anything other than plugging in. For most computer users, the idea of installing their own OS is terrifying, let alone installing an unknown OS. People take their computers to the shop when Windows starts crashing instead of trying to fix it themselves.
Public perception: Despite the problems of both ignorance and convenience, there is still a group of loyal Linux users. To cast a broad generalization, they are usually computer nerds, the sort of people who will happily build their own system and install their own OS. And unfortunately, when the public thinks of Linux, they think of these nerds. And nothing strikes fear into the heart of an average computer user like the thought of having a nerd try top teach them how to install an unknown OS.
Until Linux can find a way to convince the lowest common denominator that it is easy install and use their OS, their share of the market will remain limited to hard-core computer enthusiasts.

CIOS 110 Lesson 11 #1
On the surface, it may seem as though Mac OS X is just prettier than OS 9. Sure, there's the dock and the scalable icons, and we can't forget the little drop shadows under each open window. It definitely puts the G in GUI, and looking back at OS 9 makes one realized how dated and archaic 9 looks. But under the surface of the pretty graphics are some serious changes.
The multitasking abilities and memory protection of OS X allow the system to run many applications simultaneously without the system bogging down. The system is based on Unix, meaning that Linux software can be reconfigured to run on OS X.
Currently, Mac is moving forward with OS X, and each new development is emphasizing the visual elements and the "digital lifestyle" applications like the iLife suite, which includes iTunes (music purchasing, organization and sharing ... how this program is not considered music piracy is beyond me), iMovie and iDvd (which combine to let users easily import their raw video footage from camcorders and create movies with effects such as titles and transitions, plus dvds with menu templates and chapters). Need more proof that the OS is evolving? Well, a picture is worth 1,000 words. (Apologies for the Windows comparisons - I found the image online.)

CIOS 110 Lesson 10 #2
WebDAV is one of those terms that I heard thrown around a lot at work before I actually found out what it was. I use something that is similar to WebDAV, as most of the University is migrating web sites to the Roxen CMS. So instead of focusing on WebDAV, I'm going to focus on Roxen and CMS in general.
CMS is a great way for people to get their fingers into the Internet. Starting with simple blogs and moving up to sites maintained via a program like Roxen, it really makes the web accessible for people. Web design can be intimidating, even using a program like Dreamweaver that gives you WYSIWYG design. It's just hard for people to understand unless they have the time to devote to studying it. With a CMS, those same people can log into a site and make changes to a web page without feeling like they're writing HTML code. They are usually familiar with filling out forms online, so they probably find it comfortable to enter a headline in one field and body text in another. Ta da!! A web page.
I've had to go through a lot of Roxen training at UAF, and I've seen people who seem to have difficulty doing ANYTHING on a computer start to get the hang of the program. It scares me to think of such technically-challenged people maintaining websites just because it's a part of their admin job, but at least with a CMS, I know they won't be accidentally deleting images or pages.

It seems like the best way to protect yourself from viruses is to get a Mac. Just kidding (sort of).
It's pretty easy to avoid viruses if you use some common sense. Don't open attachments in e-mails from unknown people, for instance. Be careful about downloading and opening programs from the Internet. If it's not a trusted site, don't do it. However, you can also install software such as Norton to keep an eye on things. Norton will automatically scan all things you download. It can also be set to run regular checks of your computer looking for any viruses that may have gotten through.
In short, to avoid viruses, use a combination of software and common sense.

CIOS 110 Lesson 9 #2
Hmmm. Living in the woods, I don't have any security set up on our wireless network. Maybe that's not such a good idea, especially since I came across the concept of Wardriving and wireless hacking. Am I foolish for thinking that living remotely makes me safer?
At work, we have high security on our networks. We use Cisco and VPNs, which I will be using as I access the network from Connecticut during a family emergency. This is the problem with technology - I may have to leave the state for a while, but I'll still be able to work. Boo!!! I think that this is probably the greatest asset of wireless security, though - being able to access servers from anywhere in the world allows a company to have employees in different locations to still have access to the same resources.
Cicso offers Firewalls, attack and intrusion protection, spam and virus protection, virtual private networks and network admission control. 3Com has firewalls, secure NIC cards, wireless intrusion prevention and unified security platforms. I tried poking around the Alcatel-Lucent website as well, but their navigation system took me in many circles and I was unable to find information on what they offer, only long blocks of text telling me that they offer security.
If I were shopping for security options for my network, I would skip Alcatel-Lucent because their website was frustrating and didn't tell me anything. While 3Com offers several good security measures, I would probably opt for something from Cisco because we use it at work. If the Dept of Defense and the supercomputing center think it's good enough, it probably will work fine for me.

Sharing files over a network
Since all of your computers are connected to the LAN, they are all able to communicate with each other. In order to share folders and thus be able to work on the same files, you will have to adjust a few settings.
Locate the folder you wish to share and right click on it, then select "Sharing and Security" to pop open a control box. Under the "Sharing" tab, make sure that the "Share this folder on the network" box is checked. You will need to assign a name to the folder. Please make sure that this name is unique and easily accessible. For instance, if you choose to share your entire C: drive, please rename it MyNameC. If you do not do this, it will confuse your computer to find two C: drives.
After you have shared the folder, you will need to allow others to make changes to the contents. To do this, make sure the "Allow network users to make changes" box is checked.
To access a shared folder, use My Network Places, which you will find below My Computer in the Start Menu. You can use the "Add a Network Place" option on the left side of the screen to select frequently used files and set up a permanent connection.

Two steps to backing up your computer
Before you install any new program, make a system restore. If something goes wrong, the technician can quickly set your computer back to the way it was. Go to Start>All Programs>Accessories>System Tools>System Restore. Select Create A Restore Point, click Next and type in a brief description, then click Create.
To create a back up for either 2000 or XP, go to Start>Run and type NTBACKUP. Select the Backup Wizard and select Backup Everything On This Computer.
