Journal Week #1 SYS - AinsleyPlayer/Journal GitHub Wiki

Were you able to find your text?(Format / yes or no): 1.Yes 2.Yes

Speculate about why these files contain different data and yet show the same text:

I believe they show different texts because of how they are saved. A txt file is smaller, saving just the text, while the pdf file is saving the entire page document file. An entire page would have more grounding than a txt file.

Carefully examine the hexadecimal for this .jpg. What program do you believe this image was created with?

I have also hidden a secret message in this file, what is that message?

Adobe

You found the hidden words!

What is the integer value of the largest positive 8-bit number you are able to create?

What is the integer value of the smallest negative number you can create with a signed(remember, farthest left bit) 8-bit number?

Largest = 255

Smallest = -128

Type a phrase like “This class is great!”. The cursor is now at the end so the file and Inspector won’t show anything but the last character. As you move to the left with the arrow keys, you will be inspecting everything to the right. With one character selected, you will see it shows an 8-bit word. List those below, I’ve started:

8-bit integer = 1 character 16-bit integer = 2 characters 24-bit integer = 3 characters 32-bit integer = 4 characters 64-bit integer = 8 characters

Things I found interesting etc - That document types hold different data and value codes
