Assign # 33 - Image Encoding

1. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much memory would it require?   Four colors is also known as 2 bit color. The memory required is 800 x 500 x 2 = 800,000 bits or 100,000 bytes.

2. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much storage space would it require? Four colors is also known as 2 bit color. The storage space required is, 800 x 500 x 2 = 800,000 bits or 100,000 bytes.

3. How many different colors could one represent using two, three and four bit codes? Two bit codes is four colors.  Three bit codes is eight colors. Four bit codes is sixteen colors

4. When you add one bit to a code, what happens to the number of possible colors? It doubles.

CIS 275 Assignment 24 - Encoding Text

Encoding Text
This assignment illustrates the encoding of text information.

1. If you took a picture of your car, could you store that using the ISO 8859-1 character standard?
No, because ISO 8859-1 is the code meant to be for the text for the browsers.


2. Write the word Hello using the ISO 8859-1 character standard.
0100100001100101011011000110110001101111

a. How many bits did it take?

 40 bits

b. How many bytes did it take?

 5 bytes

c. Would it take more bytes in memory than in storage?

 It would be the same in both places.

 3. At 10 bits per second, how long would it take to transmit Hello from one computer to another?
 It would take 4 second.

4. Which contains more information 100 random bits or 1,000 random bits?

 If both of them are random bits with no code, which means no information can be translated as a meaningful.

Stanford's Free Online Class with Over 130,000 Students is Now in Session!

Stanford's free online class with over 130,000 students is now in session! Three online classes were offered worldwide free of charge,  Introduction to: Artificial Intelligence, Machine Learning and Databases. The post found here: http://cis471.blogspot.com/2011/10/open-online-classes-starting-soon-at.html goes on to talk about a similar class Professor Larry Press's took and more about Stanford's efforts. I choose to blog about this post because I signed up for two courses in the midst of excitement when I was first told. My first thought was how incredible it would be to take part in this. My second thought was wondering if I can add this to my resume? This fits in our class outline because we are both part of the computer education system.

ASSIGNMENT- Describe a Blog Post

ASSIGNMENT- Describe a Blog Post: This assignment will familiarize you with our class blog, which is typical of blogs in general. Pick a post from our class blog that is at least six months old and interesting to you, and answer the following questions:

1. What is the title of the post you chose?

The title of the post I chose from our class blog is, Proprietary research firms are an excellent source of information.


2. What is its permalink URL?

http://cis471.blogspot.com/2009/06/proprietary-research-firms-are.html 

3. What tag(s) does it have?
Labels: market research, technology


4. Why did you choose it?
I choose this post because I am currently taking a course in Market Research and I am learning about the importance of research required for business. The post mentions companies such as The Yankee Group, Infonetics, and Forrester Research who study various industries and technologies. To my surprise, these firms make a profit by specializing in only doing research for other companies. I find it interesting what companies will do for the "right" information. There is so much information out there, it is important to have reputable firms serving the market researching purpose.
