Identifying the Version and Service Pack Level of an OS (SY0-401)

- Sample video from the Security+ SY0-401 Cert Guide 3rd Edition. Shows how to find out the service pack level of Windows 7, as well as the version number of OS X, Ubuntu, Android, and iOS.
- Keep in mind that newer versions of Windows don't use service packs (such as Windows 8 and Windows 2012), but instead use updates such as 8.1, and so on. But finding the version numbers works in the same manner.
