Are a gas duster and an air duster one and the same? I need to clean inside my computer, and I have read that you use canned compressed air. The store by me has dusters that say "this is not compressed air, but compressed gas, do not inhale". Can I use these?

Well...uhhmmm. What kind of gas. If it's something inert like Helium or something I don't think It would do anything. Or Co2 wouldn't do anything either.
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

No, it's just a canned duster, and I researched it a little and I think all air dusters are actually gas, but I just want to make sure I get the right thing.

You are correct. They are all an inert propellant that is a liquid under pressure. That's why the can gets cold when you use it a long time.

Most of these use an inert gas which solves a couple of problems, one of the big advantages is that is cuts down the possibility of generating static electricity. Shuffling across a carpeted floor can produce a Electrostatic discharge (ESD) as high as 35.000 Volts, you can kill a integrated circuit with as little as 10 Volts. Remember that spark that arced across from you finger to the door knob on a winter day? The human body doesn't begin to feel a ESD until it reaches 3,000 Volts.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Thank you. My new memory cards came yesterday, I am waiting for the usb card and antistatic strap, then I think I'm all set.
