Today we continued to work on our wiki's and updating them to the best of our abilities and then we worked on our projects on Adobe Catalyst. Here are some pictures of my progress of the adobe Catalyst Project callled Final, The pictures From when I started to this day:

Today we continue to update our wiki's and we continue to work on our projects on adobe catalyst. Here are some pictures from today's progress:

Today we learned about binary code and how it works with the eight digits composed of 0 and one. They are there as placeholders on a base 2 mathematical system. The number one acts as the voltage through a transistor set up as a semi-conductor switch and the number 0 contains no voltage through the transistor. A system can hold only the tow numbers at a time and uses them. Computers are based on the binary numbering system, which consists of just two unique numbers, 0 and 1. All operations that are possible in the decimal system (addition, subtraction, multiplication, division) are equally possible in the binary system. Because computers use the binary number system, powers of 2 play an important role. This is why everything in computers seems to come in 8s (2 to the 3rd power), 64s (2 to the 6th power), 128s (2 to the 7th power), and 256s (2 to the 8th power). Thus a computer can function and think and therefore we can use them and don't have to think, because the computer does this for use with only a bunch of zero's and ones.

Today we learned about logic gates and how they work. We watched videos about logic gates and truth videos to create a visual representation. Logic gates are a physical model of a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output.Logic gates are primarily implemented electronically using diodes or transistors, but can also be constructed using electromagnetic relays relay logic, fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. Also, logic gates process signals which represent true or false. Normally the positive supply voltage +Vs represents true and 0V represents false. A truth table is a good way to show the function of a logic gate. It shows the output states for every possible combination of input states. The symbols 0 (false) and 1 (true) are usually used in truth tables. The example truth table on the right shows the inputs and output of an AND gate. We also continued to work on our adobe catalyst projects and continue t update our wiki's because it is the last day of the week and therefore it must be completed for the rest of the week.

Also inputs and outputs are gates that have two or more inputs, except a NOT gate which has only one input. All gates have only one output. Usually the letters A, B, C and so on are used to label inputs, and Q is used to label the output. On this page the inputs are shown on the left and the output on the right.
