Depends on which Linux distro you choose. Some can be put on a 1 GB usb drive, you have to check.is a 1 GB drive large enought for this purpose?
I put the full version of Ubuntu on an 8 GB usb drive and still had plenty of room left over for other files and data. It works great and took only 10 minutes to create a bootable usb drive on that 8 GB drive. You just plug that flash drive into any PC, netbook or Mac and boot up into Linux.
