My blog of interest for the week of April the 28th

How many times have you looked at your credit card statement and seen a bill for $9.87 and figured "oh well", it is only ten dollars? I know I have many of times. Maybe you might want to read what the latest research has found and how fake companies are robbing thousands of unsuspecting credit card owners and the owners just look over the small amount.

Shortcomings of Vista.............my article of interest for the week of April the 28th

Wow....a 25 items list for the new O/S Vista. The CRN Test Center made a list of these items that VARs should be aware of when using and deploying Vista. Some which include: SMB2 a new variant of the SMB protocol, which could cause compatibility with Samba or Linux, Hardware not performing adequately, and needing hardware upgrades, Third-party antivirus applications not yet compatible with Vista, Drivers that manufacturers do not have available and third-party applications not yet fully supported just to name the first five. OH MY!!!!!!!!!!!!!!!!!!!!!!!!!

Class Terms for April the 28th.

1. - Decimal Number System - A base ten number system.

2. - Base - With number systems, it describes the number of digits used.

3. - Radix - another term for the base of a number system.

4. - Most Significant Digit(MSD) - The leftmost, largest weight digit in a number.

5. - Least Significant Digit(LSD) - :) The rightmost, smallest weight digit in a number.

6. - Reset and Carry - An action that occurs when a column had reached its maximum count.

7. - Binary Point - A symbol used to separate the whole from the fraction in a binary number

Class Discussion on April the 28th.

This weeks discussion was on Number Systems and Codes. We discussed the history of the Liebniz's Language of Logic. Gottfried Wilhelm Liebniz was born in Germany in 1646. In 1676, he turned his focus to mathematics. His focus was on the binary number system. Ironically, for all of his work, he failed to make the connection between the famous 1666 essay and binary to the universal language of logic he was seeking. The discovery remained hidden until George Boole uncovered it a century later after Liebniz's death. We also discussed the Decimal Number system which has a base of ten. We also learned that the term radix means base. We talked about the reset and carry operation. Finally, we talked and learned the binary number system. We also learned how to convert the decimal number system into binary number systems and binary number systems into decimal number systems.

Terms for April the 21st.

1. - Analog Data - Data recorded very similar to its original structure.

2. - Analog Circuit - An electrical circuit known as an operational amplifier.

3. - Linear Circuits - the basis for neural membrane models.

4. Ohm(Kiloohms) - the unit of resistance. The larger values are measured in
kiloohms which are equal to 1000 ohm's.

5. - multimeter - a device that has the capability to turn analog into digital and digital into analog.

6. convergence - the combinations of communication and computers and the combination of the two.

My blog of interest for the week of April the 21st.

It has only been a month since Vista released the SP1 to Windows in 5 languages, and it is now been downloaded by millions of people on their PCs. Now, Vista has announced the next stage that anyone running Vista in any of the supported languages can now download this manually. I guess Vista has its good and bad points.

Look out Wirless Carriers: Cellular South?

Look out wireless carriers, Cellular South is offsetting horrid early termination fees by crediting their account with $200.00. Cellular South believes customers should have unlimited calling, texting, emailing over the web over their wireless cell phones. I know I will be looking into this and keeping up with Cellular South.
