From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Your generic "barcode" for something like a UPC is considered a 1D barcode and uses things like the spacing of the lines and thickness to encode data. Although some 1D barcodes can detect the barcode is damaged they cannot do error recovery.
Your 2D barcodes, like QR or Data Matrix, store data in both directions and depending on format can have varying levels of error correction (duplicate data) built into the barcode. They also obviously can take up less room and hold the same or more data as well. You do need a scanner that can do 2D barcodes though, as not all scanners will read them.
