- the time it takes for the head to stabilize before reading can occur 22. latency - after instructions have been interpreted and the actuator begins to move and the head has reached the selected cylinder and has stabilized and it is still not ready to read 23. FIFO/seek-time and access-time optimization - First in First Out the tasks that are queued up and the first tasks requested are the first tasks performed/seek time involves the radial positioning of the head, tasks are ordered based in their radial positioning to minimize seek time/ takes account in both radial and angular position to minimize access time which included seek time and latency 24. servo information- information on the disk about location on the disk/ can be placed in dedicated sectors(wedge servo) on dedicated platter side (dedicated servo) and spread throughout (embedded servo)

25. voice coil/feedback - voice coli uses feedback mechanism to locate the data/ feedback means taking some output and putting it back in as input. Like when the head is reading information from the platter 26. low-level (physical) formatting/high level formatting - establishes the tracks, sectors and writes the servo information(hard drives this is done by the manufacturer for a floppy disk it can be done by the user)/partition boot sector, system ID byte, information for the filesystem, data on bad sectors, lose data 27. partitioning - separates the disk into logical pieces 28. landing zone -reading head is not supposed to touch the platter(floating/flying height), if it does you have a head crash, region where you designate where the head can come in contact with the disc when it stops where no information will be lost/head parking 29. OEM - Original equipment manufacturer/ hard disk drives and jumpers 30. cylinder skew/head skew - the staggering from track to track on a give platter/ the staggering from platter to platter within the cylinder 31. logical volume/extended partition 32. primary partition - designated ad “active” and under normal circumstances one boots from the active drive 33. Master Boot Record/volume boot sector -the first thing read from the hard drive when the computer starts, consists of the Mater Partition Table and Master

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
