|
What is the name for the areas that a typical hard disk is divided into(they look like the wedges in a pie)?
|
Sectors. Look like pie shaped wedges.
|
|
|
Which IDE-related standard is able to transfer data at 33MBps?
|
UltraDMA (UDMA)is able to transfer data at 33MBps.
|
|
|
Which SCSI implementation can transfer data at up to 10MBps?
|
Fast SCSI-2. SCSI transfers data at 5MBps, Fast SCSI-2 at 10MBps, UltraSCSI at 40MBps, and Wide Ultra2SCSI at 80MBps
|
|
|
What are the most common sizes for floppy drives?
|
3 1/2 and 5 1/4. 3 1/2 is more common now.
|
|
|
The process known as_______ converts binary information into patterns of magnectic flux on a hard disk's surface.
|
Encoding. This is how data is written to the surface.
|
|
|
A typical hard drive has how many bytes per sector?
|
A typical hard drive has 512 bytes per sector.
|
|
|
How many devices can be used by a single IDE Controller?
|
2. Each IDE Controller can have a single master and a single slave device.
|
|
|
Disk specifications are generally given as what?
|
The capacity, the seek time, and the spin speed of the drive
|
|
|
What are means of disk organization?
|
Tracks, Sectors, and Cylinders
|
|
|
The device that convert signals from a IDE drive into signals the CPU can understand is called a_______.
|
Paddle board/Sometimes erroneously called the controller card.
|
|
|
If a typical hard disk has 903 cylinders, 12 heads, 63 sectors per track, and 512 bytes per sector, what is its capacity?
|
333MB. The way to solve this problem is to understand how the math works. Take (903x12x63)/ 1,024 and the answer is roughly 333MB. The division by 1,024 is necessary to convert bytes to Megabytes.

|
|
How do you low-level format a SCSI drive?
|
You don't. Just as IDE drives you don't ever want to low-level format a SCSI drive. It can render your disk unusable.
|
|
|
How do you low-level format an IDE drive?
|
You don't, it done at the factory. Low-level formatting should not ever be done because it is done before the drive leaves the factory.
|
|
|
Suppose you have an internal SCSI hard drive and two external devices: a scanner and a CD-ROM drive. The scanner is the last device on the chain. Which device should be terminated?
|
Hard disk and Scanner. In this example you would want to terminate the internal hard drive, not the adapter, and terminate the scanner because it is the last device of the external chain.
|
|
|
Which implementation of SCSI has a transfer rate of 20MB/sec?
|
Ultra SCSI, or SCSI-3, standard supports a transfer rate of 20MB/sec. This is twice as fast as the FAST SCSI-2 implementation.
|
|
|
How many devices can SCSI-1 support(including the controller)?
|
8.Including the controller card, ScsI-1 can support up to 8 devices, with address IDs ranging from 0 to 7.
|
|
|
What must be done when installing SCSI devices?
|
Terminate the first and last devices in the chain. Set unique SCSI ID number.
|
|
|
You have just replaced the floppy drive in a PC. Upon turning the computer on, you discover you can't boot the the floppy drive. The drive light turns on during power up and stays lit until you turn the computer off. What should you do to solve this problem?
|
Change the drive type in the CMOS setup. Reverse the floppy drive cable.
|
|
|
Low-leveling a disk drive means______.
|
Organizing the disk into sectors and tracks.
|
|
|
What are features of a disk drive?
|
A)Rotating disks are coated with a special substance sensitive to magnetism.
B) As the disk rotates, the particles of the substance become polarized or magnetized, indicating a 1. C) The unpolarized areas indicate a 0. |
