The Definition of Harddisk
Hard disk is medium data storage on a computer that consists
of a collection of magnetic hard disks and spinning, as well as other
electronic components. Hard disks use a flat disc called the platter, which on
both sides are coated with a material that is designed to be able to store
information magnetically. Platter-platter by punching holes in the center are
arranged and rearranged on a spindle. Platter spinning at very high speed which
is controlled by the spindle motor that is connected to the spindle. Special
literacy electromagnetic tool named head mounted on a slider and is used to
store information in a disk or read. Slider mounted on the arm, all of which
are connected mechanically to a single collection on the surface of the disc
and is connected via a device called the actuator. There was also the logic
board to regulate the activity of other components and communicates with the
PC.
ATA / EIDE. EIDE hard disk (Enhanced Integrated Drive
Electronics) or ATA (Advanced Technology Attachment) is the latest version of a
stAndard disk interface suitable for connection to the bus. Many manufacturers
have a range of disk with a disk interface EIDE / ATA disk can be connected
directly to the PCI bus and roomates which is used in many PC (personal
computer).
SCSI. Many disks have interfaces designed for connection to
a standard SCSI bus. The disks tend to be more expensive, but have better
performance which is possible due to excess SCSI bus than the PCI bus. Access
to the same can be done for many disk drives as the drive interface is actively
connected to the SCSI bus only when the drive is ready to transfer data. This
is especially useful in applications where there are a large number of requests
for small files, which often happens in a computer used as a file server.
RAID. Promises great performance and provides a large and
reliable storage. Disk is used both in high-performance computer and in systems
that require dramatically higher reliability than normal levels. However, with
the decline in prices to a more affordable level, the disk becomes more
attractive even for a computer system with size – average.
SATA. SATA hard disk of the type (Serial Advanced Technology
Attachment), the disk interface ATA (Advanced Technology Attachment) by using
the serial version of the thin cable that has small wires. Total about two-thirds
of total hard drive cable with type EIDE or ATA disks are numbered 39 pins and
SATA has very high speed data transmission and reducing latency. So, this
serial bus is able to exceed the speed of parallel bus.
my opini: banyak sekali sekolah yang belom kesentuh dengan fasilitas yang lengkap terutama pada komputer.karena, Pada zaman sekarang komputer sangat penting, terutama untuk bekerja maupun untuk mencari informasi.
