hex number is 138, what is the number in binary?

EvilAngel · Post by **EvilAngel** » Thu Jun 21, 2001 12:15 am

I mean like 132FAB + FEA451

remember I'm new

The answer I got was 121B3FC for the above problem... <crosses fingers> Is it right?

10001010, you can check this with your calculator in win9x, just select scientific view, enter the number in hexidecimal, then change the radio button to binary, it will give you the answer above.

I just completed A+ and Network+, so I've been using this a lot in class.

I got it wrong... grrr the right answer is 111D3FC for my problem... I didn't know that MS had a hex calculator.. thanx man.

I have a question for ya... would it be benificial to learn it through writting it or useing calcu;lator? I mean how often do you have to use it by writting it out?

I did Binary to Decimal and Deciman to Binary in my Network Infrastructure class for my MCSE stuff.... we have to know it so we can figure out like what subnets certain IP's are in etc....

but i've never messed with Hex, i'd love to learn it sometime though.....

dude! binary is actually the easiest to learn,,you will do just fine.....no sweat.

Geez, binary is all but fun compared to some of the other ones. We had to learn them all by hand, with no calculators.

hexidecimal, octal, binary, back to hex, over to decimal...sheesh

I haven't had to convert binary to hex in the real world setting up any networks, but you will need to know it to pass most cert test.

Also helps to know it just so you know how networking basically functions.

Don't know if you got to this in class yet, but any device that connects to a network has a MAC address, which is in Hexidecimal. Kind of tripped me out, when I thought about the millions of network cards, routers, modems, ect. that have thier own MAC address and no two are the same.

I'm happy for you, that you got into class. Probably the best thing you have done for yourself in a while. Helps to keep your mind busy and not thinking about the things that had control of your head in the past.

:2cool:

Hey Evil, nice to see you learning the "code"

Binary is fun, try memorizing the first 12 numbers, and learn how to add and subtract by stacking numbers on top of each other.

The other codes are a little harder, it just gets to be a pain when you have to go from one code to another to get to another.

No, but you do for Network+ it helps understand how things like IP's and Subnets work together etc....

ok cool, i guess i'll learn it then lol
