44. A connection point on a device or computer - sometimes called a socket.






45. When a mount point exists between a partition or volume to a folder on another volume - the drive path is the path (including a drive letter) to that partition or volume.






46. Aka alternating current.






47. A standard used in laptops that is based on PCI. The biggest difference is that Mini PCI is much smaller than PCI
