Read about this malicious threat. You must know what this is!!!!

A worm is a type of virus or replicative code that situates itself in a computer system in a place where it can do harm. There are viruses (such as Melissa) that don’t “worm themselves in” to a place where they can do much harm and simply replicate themselves by e-mail to many computers. Worm.ExploreZip is an example of a worm. Like most computer viruses, worms usually come in Trojan horses

Here is another excellent company in my opinion. I have also ordered parts from them and have visited their store as well. I feel that all their product is quality and the prices are fair.

Normally I will not endorse a company or a product. However, I have been ordering parts from them for about one year. In my opinion they have good products and they deliver them fast and in good shape.

I will put periodic links in here. These are only products I feel are actually good.

This is a review on what I feel I have learned about VISTA since its release.  First and foremost it takes quite a bit of RAM.  It is my experience that to run VISTA HOME PREMIUM you “must” have at least 2 GIG of RAM.   I also know that you don’t want to try to “upgrade” to Vista for a computer that is more than two years old.  You must have a fast motherboard with a Duo-Core processor in my opinion.  You also need a good size hard drive due to the fact the operating system takes up quite a bit of storage space.  Be sure you read the system requirements if you do want to upgrade.

If you have a Windows 98 computer and you need to upgrade do NOT try to put VISTA on that machine.  Either donate the computer or see if somebody in your area will recycle it.  Do not just throw it away.  It contains numerous component that are not good for the environment.  Cost is not economically feasible.  It will cost you more to upgrade an old computer “properly” than it would be to buy a new one. The mother board and processor will need to be replace at a minimum if you really want to spend the money.

Over the course of time I plan to write my own personal experiences about computer. If I see something that should be brought to your attention I will most certainly try to do that as well.

Here is some information that I feel is vital to understanding Hard drives and how they store data:

Why Do I Have Less Drive Space?
Your hard drive may show less space than the published specifications due to a number of reasons.

1. The way size is calculated and displayed.
2. Any “Partitions” on the disk will change the total in a specific partition.
3. Hidden files and folders decrease available space.
4. Compression increases the apparent size, but not the physical size.
5. Drives larger than the OS or Drivers natively supports.

First, the definition of a megabytes (or gigabytes) is a unit of data storage capacity measured in 1,048,576 bytes (or 1024KB). The larger the numbers, the more apparent the size difference will be when listing the size as megabytes (or gigabytes) versus bytes. Actually, both numbers are correct. The noticeable difference is due to the 1024KB definition of a megabyte. This is why a 95.3GB hard drive can also be listed as having 102 billion bytes of total space.  Just think of it as “round off”  In the screen shot at right: The first number is the total number of bytes, the second number is based on the number of megabytes or gigabytes.

Second, some computers have a non-DOS hard drive partition that is used for features such as Save to Disk, Hibernation, or Recovery. This partition is not normally reported by the operating system, although it can be viewed using a disk partition utility.  This is very common on desktops and laptops.  NOTE: Partition information will be created or formatted automatically during initial system setup and a system recovery.

Third, by default, all system files are hidden and cannot be seen. This may adversely affect the reporting of available hard drive space. You can set your Folder Options so you view system and hidden files and folders, but do be careful as changes to system files can adversely affect your system.

Fourth, if you turn on Compression for a drive, it will increase reported free space and used space, but since compression is based upon the actual contents, this number is not fixed, but will change as files are added or changed.

Fifth, older operating systems did not support some of today’s larger drives, so the total space reported may be much smaller than the drive specifications.

It is also worth noting that bad sectors are corrected by your operating system and can change the total drive space, free space, or used space as well.

So as long as a drive is reporting a value approximately close to the specification value, you can be comfortable that you received the right drive and that you are getting to correct data storage.  Of course, tuning of your drive’s partitions and options can yield optimal values, but this is not something for the average user to explore.
