Every new computer that’s brought home from the store has an operating system installed onto it. But what most new computer users don’t realize, is that without an operating system, that computer would be a simple shell of possibilities. A powered computer lacking an operating system wouldn’t display anything more than a bunch of confusing text messages that describe the computer’s boot process. At the very end of this process, the computer looks for an operating system and if not found, it will prompt the user to tell it where it is.

Earlier computers didn’t have an operating system and if you have experience with the computers of the early eighties, you’ll remember that most to them didn’t even have a hard drive! These old computers booted an MS-DOS type operating system from drivers stored onto a floppy disk, and in order to use a program, users would remove the boot floppy and then insert a new floppy that contained the program. The floppy not only stored the program

Today, more and more people are using their computers for everything from communication to online banking and investing to shopping. As we do these things on a more regular basis, we open ourselves up to potential hackers, attackers and crackers. While some may be looking to phish your personal information and identity for resale, others simply just want to use your computer as a platform from which to attack other unknowing targets. Below are a few easy, cost-effective steps you can take to make your computer more secure.

1. Always make backups of important information and store in a safe place separate from your computer.

2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to www.windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows computer. Also go to www.officeupdate.microsoft.com to locate possible patches for your Office programs.

3. Install a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all easily access your computer from the Internet. Consideration should be given to the benefits and differences between hardware and software based firewall programs.

4. Review your browser and email settings for optimum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malicious programs into your computers. While cookies are relatively harmless in terms of security concerns, they do still track your movements on the Internet to build a profile of you. At a minimum set your security setting for the internet zone to High, and your trusted sites zone to Medium Low.

5. Install antivirus software and set for automatic updates so that you receive the most current versions.

6. Do not open unknown email attachments. It is simply not enough that you may recognize the address from which it originates because many viruses can spread from a familiar address.

7. Do not run programs from unknown origins. Also, do not send these types of programs to friends and coworkers because they contain funny or amusing stories or jokes. They may contain a Trojans horse waiting to infect a computer.

8. Disable hidden filename extensions. By default, the Windows operating system is set to hide file extensions for known file types. Disable this option so that file extensions display in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any unusual file extensions that do not belong.

9. Turn off your computer and disconnect from the network when not using the computer. A hacker can not attack your computer when you are disconnected from the network or the computer is off.

10. Consider making a boot disk on a floppy disk in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this step before you experience a hostile breach of your system.

Save hundreds on your next Dell purchase – Amazing secrets revealed

Getting ready to buy a Dell computer? Before you do so, you had better read the following tips, because they can save you big on your next computer purchase. Before you get started, I would like to give you some background on Dell and their marketing/pricing strategy. Dell Computers is the largest manufacturer and retailer of computers in the world. They have about a 15% market share of all computers sold in America. Because Dell only builds a computer when it is sold, it enables Dell to keep very low inventories, and therefore, a very low price. Moreover, you can only buy a Dell at Dell. They have no retail presence. No middlemen!

Dell utilizes many channels of advertising to get the word out about their low prices. You have probably seen their ads on TV or their full page print ads in the newspaper. You may have even received a Dell catalog if you have purchased from them before. What you probably haven’t noticed is that the price of these seemingly equivalent systems vary greatly depending on where you saw the ad. This is the very first lesson on being “Dell smart.” Dell is NOT transparent in their system pricing. This means, depending on where you learned about the computer deal can greatly impact the price you pay.

Okay, so if Dell does not consistently price computer system ads, where should you go to get the best deal? That’s simple — the Internet. And by Internet, I do not mean going straight to Dell.com! To become “Dell smart,” you need to choose a Dell computer that is right for you, one that suits your needs. Computer shoppers often overspend on options they will never use. Go to your favorite search engine and look for a buying guide. After you narrow your search, go back to your search engine (I use Google) and enter “model name + review.” Read a few independent reviews about the model you’ve selected and find out what other people are saying. What are the system’s pros and cons?

Now that you know what you are looking for, let the real money saving begin! Go back to your favorite search engine and enter the words “Dell Coupon Codes.” What you should get in return is a list of Dell affiliate web sites that supply FREE coupons from Dell. These coupons are not advertised, as Dell tries to keep these for the savviest shoppers. More often than not, Dell has a $750 off coupon that can be applied at checkout allowing you to save big! Sometimes, these coupons can even be stacked, meaning you can apply more than one coupon towards your purchase, or they can be used in combination with rebates or other instant savings. Check several coupon sites until you find a coupon that works for your model. Make sure you read the fine print, and verify that the coupon is not expired. Some coupon sites give step-by-step instructions on applying coupons so make sure to do your research!

Once you have found the relevant coupons for the system you want to buy, you are ready to go to Dell to make your purchase. Purchasing a computer from Dell requires that you go through several pages of options and add-ons. This is where buyers typically get bogged down as they are overwhelmed by a number of options and upgrades. Be sure to use the buying guides you came across to identify which features and upgrades are right for you. And be aware that you can often down-grade from many of the default Dell options. For example, Windows Media Center and Windows XP Pro are practically the same operating system. However, Dell sometimes defaults to XP Pro in their options which costs significantly more than Media Center. So, downgrade whenever it makes sense for you and your needs. Once you have gone through the pages of options, you will be at checkout. This is where you will apply your coupons, select the cheapest shipping and pay tax. If you followed these steps, you should be saving hundreds of dollars for the computing system that exactly meets your needs.

Let’s recap:

1. Dell prices are not transparent, always search the internet.
2. Research the right model for YOUR needs. Use a buying guide.
3. Search for a review of the model you selected on a search engine. Use “model name” + “review”
4. Go back to your favorite search engine and enter “dell coupon codes.” Find a good coupon site with current coupons and good instructions.
5. Go to Dell, select your model, and DOWNGRADE unnecessary options and add-ons.
6. Apply your coupon at checkout (stack whenever possible)!
7. Use the lowest priced shipping.

Pat yourself on the back, because you have now saved BIG!
