Muddiest Points: Week 3 (09/16/14)

Greetings, and welcome to my Muddiest Points for LIS 2600, Week 3!

I was wondering if you could integrate RLE within an image that requires more complex compression techniques.  That is, can there be more than one method of compression within a single file?  Or is this illogical?

Also, I am still trying to get my head around binary.  I though I understood it, but then there was that Foxtrot comic and I got confused.  I made a little chart, and am wondering if it's correct?

So, if there are four bits, there are a potential for 16 values.  I tried to make a chart and would like to know if I got it right.  I know it isn't necessarily relevant to what we were learning in terms of compression, but I didn't understand the explanation very well; now I want to know if I understand the concept.  So, here's a chart of 4 bits (four powers of two, right?) and their decimal equivalents.  I apologize that the underlining is a little weird:

2³            2²                 2¹              2⁰          Decimal Equivalent

0              0              0              0  ………………. 0

0              0              0              1  ……………..…1

0              0              1              0  ………………..2

0              0              1              1  ……………..…3

0              1              0              0  ………………...4

0              1              0              1  ………………...5

0              1              1              0  ………………...6

0              1              1              1  ………………...7

1              0              0              0  ………………...8

1              0              0              1  ………………...9

1              0              1              0  ………………...10

1              0              1              1  ………………...11

1              1              0              0  ………………...12

1              1              0              1  ………………...13

1              1              1              0  ………………...14

1              1              1              1  ………………...15

Thanks!
