Any computer science majors here?(or someone who knows alot about computers)

[adamb100]

Taking a computer science class @ UWM and the professor covered Logic Gates yesterday(and then tied this into Binary, decimal and hexidecimals). I kinda got lost here and I'd like someone to fill me in on these "logic gates".

 

Thanks. http://forum.brewerfan.net/images/smilies/smile.gif

I know I learned that stuff at Marquette as an Electrical and Computer Engineering major, but it's pretty fuzzy. I think it's one of those things that got flushed from memory shortly after the class ended. http://forum.brewerfan.net/images/smilies/smile.gif

What exactly are you fuzzy on? I've taken a couple of classes with this type of material, and I'd like to think I know what I'm talking about. http://forum.brewerfan.net/images/smilies/smile.gif

Like to go in detail. I dont grasp the whole gates thing. I also dont grasp converting binary to hexadecimal and decimal and back.

Binary, hexidecimal and decimal are all different ways of displaying numbers.

 

11 in binary means three.

11 in hexidecimal means seventeen

11 in decimal means eleven.

 

1 hexidecimal number is 4 binary numbers (as it represents 0 to 15 -- or 0 to F), so, 1111 is fifteen, which is F in hex.

 

To convert binary to decimal:

 

1011 (for example)

 

The number on the left is mutiplyed by 2 to the 0 power. (1*1)

The next number is multiplyed by 2^1 (2*1)

The next by 2^2 (4*0)

and the last by 2^3. (8*1)

 

Then you add them up. 8+0+2+1 = 11.

 

For hex, its the same principal instead of using 2 to the power of, you're using 16 to the power of.

 

Hope that made sense.

It would probably be to your best advantage to talk to your professor, TA, or classmates if you don't understand something. Just a suggestion http://forum.brewerfan.net/images/smilies/wink.gif
