How do you describe a hard drive?

Question

I need to know asap...coursework SOS, hahaha

Answer 1

- In a personal computer, a Hard Disk Drive (HDD) is the device that stores the information used in the PC. This includes the Operating System, applications, system files, and documents used by the system. The Hard Disk Drive often shortened to just "Hard Drive" or "Hard Disk" are actually different. The Hard Drive contains a number of platters(disks) which spin. An arm much like the needle arm of a record player moves back and forth accessing the data. Either term can be used to describe the unit as a whole.



- HDD storage is measured in Gigabytes (1 Billion Bytes). HDDs connect directly to the Motherboard through one of two interfaces, IDE or SCSI. Integrated Drive Electronics(IDE) is the standard interfaced used to between the Motherboard and Hard Drive. All Motherboards today have the Enhanced Integrated Drive Electronics(EIDE) connections and controller built on the board, EIDE is an enhanced and faster improvement on the original IDE standard.

see i will tell you how a harddisk work, harddisk is made up of platters, there are some platers in every hdd(harddisk drive), which are placed one upon the other. a plater is a disk like thing, which has film metarial on it's either side, the platter has traks which run from as a circle in the harddisk. there can me many tracks, from the begining and end of a platter, and on the other side as well, a platter has two sides, and so we have two heads to write data on both the sides. there are molicules on the film metarial, and for every molicule the allignment is n-s(north and south), it can be n-s or s-n as it's orientation. is the first molicule on which the data is being written is n-s, or s-n, it's taken a default, and the head with a coil, makes the next molicule as ( n-s) then again (n-s) if the data is 0 and if the data is one then (n-s) then (s-n), so, i think you getting me, and yes one more thing, there may be several platters and every platter has two sides, and many tracks on a platter, so if you look from the upside, you will find that the tracks are all one after the other, means track 1 on platter number 1, then track 1 one the platter number 2, just under it. and then so on, it will become a cylinder sort of, and it's knows as cilynders.

Answer 3

A hard disk uses platters (disks). Each platter has a planar magnetic surface on which digital data may be stored. Information is written to the disk by transmitting an electromagnetic flux through a read-write head that is very close to a magnetic material, which in turn changes its polarization due to the flux. The information can be read by a read-write head which senses electrical change as the magnetic fields pass by in close proximity as the platter rotates.



A typical hard disk drive design consists of a central axis or spindle upon which the platters spin at a constant rotational velocity. Moving along and between the platters on a common armature are read-write heads, with one head for each platter surface. The armature moves the heads radially across the platters as they spin, allowing each head access to the entirety of the platter.



The associated electronics control the movement of the read-write armature and the rotation of the disk, and perform reads and writes on demand from the disk controller. Modern drive firmware is capable of scheduling reads and writes efficiently on the disk surfaces and remapping sectors of the disk which have failed.

there is not any ram stressful rigidity a working laptop or laptop makes use of the stressful rigidity for setting up os and critical applicstions ram is rando get right of entry to reminiscence its like a reminiscence thats only used while doing applicztions
