Lab 10

Hartley’s information is concerned with logarithmic equations. And Shannon’s information is concerned with calculating information from a source to a receiver. Shannon's measures the information content of random variables and a measure over sets.

Excel (lab 9)

Before this lab I was not familiar with Microsoft excel or the math equation that we learned in the lab today. Prior to coming to this lab I did not no how to calculate the statistics properly. Now after completing the lab I feel more comfortable when using these equations. At first it was frustrating when the application was doing other than what I wanted it to do. But after some practice I found out that it was me that was doing something wrong. I also didn’t no that this program could do the type math and organizing that it is capable of. It took some getting use to, but I think I finally got the hang of it. I also like many ways that you can display your information other than just numbers. Excel has a lot of different graphs and pie charts that I didn’t know about. I personally think that inductive modeling forces people to think on a higher level than what they normally would. Inductive modeling makes people think outside the box in ways that people normally would not. To me this form of thinking is more exciting than reading out of a book. It basically gives the person a chance to put the pieces together and come up with hypothesis and assumptions. I like the data analysis portion of this lab as well because you get the satisfaction of seeing the final product once the calculations are complete.

DeMorgans Law

Task 2
This circuit only works if both switches are 1 or 0 and it will not work if it is one or the other.

Task 3
After running all four combinations, the binary values A and B are the same each time.
DeMorgans Law is true because it follows logical operations effectively.

Converting Binary and Decimal Numbers

When converting the binary number 110010101 to decimal you first must list the number with powers above from right to left. Then start with 2 to the power of 0, and go up one per power. Stop when you have reached the same amount in binary numbers. For every binary number one that you have, write the power that above it. Write each power out and add them together and you should get 405 as your answer.

When converting the decimal number 529 to binary, you simply divide by 2. When dividing the number 529 if it divides evenly by 2, mark it as a 0 and if it does not divide evenly put a 1 next to that number. Each time you divide the number should go down by half, when it does this just mark down a 1 or a 0 if pending if it divided evenly or not. When you are complete with these steps it should leave you with the binary number.


NUMBER SYSTEMS
A positional number system is the value of each digit determined by its position. A non-positional number system is one that does not have to be positioned in any particular way to indicate the value of the number. a non-positional number system could also depend if it corresponds to something else.

Using the Steel Account

My first time using the steel account was somewhat confusing. After going through the some of the steps I did learn about some of this account. The first thing I learned was, steel07 – finger , it is a good way to find out information about someone that are linked to the network. I learned that the Cd/ allows you to go to the root of the steel account. Using whoamis shows who I am, and minor information about me. I also learned that using Is-la tells whether something is a file or a directory. I think I learned some key components to the program that will be very helpful.
