Assignment #33

1. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much memory would it require?

We would need 200kBytes of memory.

2. An image is 800 by 500 pixels, and each pixel can be one of four colors. How much storage space would it require?

We would need 200kBytes of storage.

3. How many different colors could one represent using two, three and four bit codes?

Here are the different colors one can represent using these bits:

Two bits = 4 colors

Three bits = 8 colors

Four bits = 16 Colors

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

When you add one bit to a code the number of possible colors doubles.

Assignment #24

1.  If I took a picture of my car I would not be able to store it using the ISO 8859-1 character standard because this standard is only used for texts, numbers and special characters, not pictures.

2. Hello written in ISO 8859-1 character standard is:

01001000 01100101 01101100 01101100 01101111

a. It took 40 bits
b. It took 5 bytes.
c. This information would take the same amount of bytes in both memory and storage.

3. It will take 4 seconds to transfer Hello from one computer to another.

4. Neither 100 random bits nor 1,000 random bits would have any information because the bits are random. In order to have information the bits would have to be organized using code.

Reviewing a blog

What would be the impact of online sales tax? This is the question one blogger asked and answered by giving both sides to the argument on his blog “The Impact of online sales tax”. According to the blog internet sales tax would increase revenue for states, which would help pay for the salaries of many state workers. This is a great outcome since most states are struggling to pay for services, bills and employees, but is the tax regressive. Taxes are only good when they are imposed on those who are well off not those who are already suffering.

The reason I picked this blog is because I was interested in the use of internet sales tax. I wanted to know what it was all about and why the state of California is just talking about it now. Also, I wanted to find out if it was beneficial or would hurt our fragile economy.

Based on the information given this blog would fit under internet concepts as an implication.
