Today I learned how to open up a hard drive and put it back together even tho it didn't work but it was really cool learning the insides of the tower. We did plenty of notes for most of the day on hardware and many things that I did not know about before.
Hard Drive:
The hard drive is what stores all your data. It houses the hard disk,
where all your files and folders are physically located. A typical hard
drive is only slightly larger than your hand, yet can hold over 100 GB
of data. The data is stored on a stack of disks that are mounted inside
a solid encasement. These disks spin extremely fast (typically at
either 5400 or 7200 RPM) so that data can be accessed immediately from
anywhere on the drive. The data is stored on the hard drive
magnetically, so it stays on the drive even after the power supply is
turned off.
Terms To Know:
TERMS TO KNOW:
-Zone Bit Recording is used by disk drives to store more sectors per track on outer tracks than on inner tracks.
The inner tracks are packed as densely as the particular drive's technology allows, but with a CAV drive the data on the outer tracks are less densely packed.
-Pixel Dust hard drive used to refer to a technology that seemingly does the impossible. Was announced in 2001.
"pixie dust" is often used to refer to a technology that seemingly does the impossible.
-Platter based HDD is the circular disk on which magnetic data is stored in a hard disk drive. Boot up time is slow.
-SSD A solid-state drive SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives.
a high-performance plug-and-play storage device that contains no moving parts. Can wear out over time. Can boot up faster.
