22. A___________________can be used to test a USB port.






23. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






24. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






25. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.

29. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






30. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi
