Ceo Steve Ballmer say Vista is a work in progress

The Ceo of Microsoft Steve Ballmer famously called the much-hyped Microsoft Windows Vista a work in progress . Steve Ballmer said during the conference, there still work to be done on Vista a very important piece of work. I think we did a lot of things right, and I think we have a lot of things we need to learn from"promptly adding. Vista is bigger than XP. It going to stay bigger than XP,

My assessment of Class

Today Class talked about analog to digital,ASCII which stand for American Standard Code for Information Interchange. It was good to try to understand how data is converted to AC Electronic Signal and DC Electronic Signal. The three basic blocks within a computer are Microprocessor, Memory(Rom or Ram), and Input/Output Interface. This class gave a difference view of how the computer operate from the inside.

Terms & Concept

1- The basic types of signals are analog and digital.

2- ASCII Stands for -American standard code for information interchange.

3-IC Stands for Integrated Circuit

4- A Digital signal has two levels.

5-Digital communication of characters is possible by using ASCII

6-To digitize is to convert an analog signal into a digital signal.

7- An Integrated circuit is also called a chip.

8- CPU stands for central processing unit.

9- An Analog Circuit is also called a linear circuits, since linear by definition is a variation of an output in direct proportion to the inputs.

10- Multimeter is a device that is able to measure voltages, current and capacitors.

11-OHM-is the electric resistance between two points of a conductor, when a constant potential difference of 1 volt, applied to these points produces in the conductor a current of 1 ampere the conductor not being the seat of any electromotive force
