line. SCSI hard drives are used primarily on server computers.
Magnetic hard drive read/write heads are controlled by an _____________, which moves the
read/write heads across the disk surfaces in unison. - correct answer ✔✔ actuator
Scenario:
You recently installed a new RAID controller card in a PCIe expansion slot on your computer.
