41. The Institute of Electrical and Electronics Engineers - an international nonprofit organization that sets standards as part of its charter.






42. A registry key that exists within another key.






43. A Windows sleep mode that uses hard drive space to save all the programs and data that are in memory at the time you choose this mode. The computer then completely shuts down and requires no power while it is hibernating.

45. Aka virtual file allocation table.






46. The connecting point of a mounted drive to a folder on an NTFS volume.
