Prof. Mon Arjay Fernandez Malbog Jan. 15 2013 Computer Number System Binary‚ hexadecimal‚ and octal refer to different number systems. The one that we typically use is called decimal. These number systems refer to the number of symbols used to represent numbers. In the decimal system‚ we use ten different symbols: 0‚ 1‚ 2‚ 3‚ 4‚ 5‚

structure The basic structure of the Arduino programming language is fairly simple and runs in at least two parts. These two required parts‚ or functions‚ enclose blocks of statements. void setup() { statements; } void loop() { statements; } Where setup() is the preparation‚ loop() is the execution. Both functions are required for the program to work. The setup function should follow the declaration of any variables at the very beginning of the program. It is the

On a scale of 1 to 10‚ I would rate my success in the Hex Auction 6 out of 10. This is because I was unable to buy many hexes that I aimed for due to lack of money. The one thing that I think I did really well during the auction was raising the prices of the hexes because many citizens needed them‚ so they were willing to pay anything just to own the property. This also caused their money to decrease and left and advantage for me‚ because they had less money towards the auction which meant they would

DATA REPRESENTATION CPU uses electronic elements such as switches‚ which are represented in two states i.e.‚ on/off state (high/low state). These two states are indicated as 1 and 0. In other words‚ computer operates only in two digits 1 and 0. Hence‚ our ordinary decimal number system consisting ten digits (0-9) do not suits the data representation of CPU. It works with simple binary system. BINARY NUMBER SYSTEM It uses two symbols or digits i.e. 0 and 1. And all the symbol‚ Arithmetic
