Version refers to a specific release of a tech product such as software or hardware. Versions have unique identifiers, such as numbers, dates or codes. The general practice is that larger numbers and more recent dates are used to designate newer versions, ie Chrome 56 is more recent than Chrome 44. Numbers don’t have to be sequential, and for updates and small changes, the overall version name often stays the same, with only an internal (and to the casual user difficult to find) build number revealing the exact version.
