Storage medium that stores data in the form of magnetic patterns on a rigid disk. Modern hard disks are usually made of several thin films deposited on both sides of the aluminum, glass, etc. substrate. Hard disks are much more rigid than floppy disks, spin much faster than floppy disks, and can transfer data faster and store more in the same volume.
Also referred to as the hard drive. The hard disk is a fixed disk located within the computer. Compared to floppy disks, hard disks are both faster and safer to use and will hold enormous amounts of data compared to a floppy disk. Computers sold now have hard disks ranging between 80 GB and 250 GB in storage capacity.
A disk drive, usually fitted out of sight inside a PC, on which the programs used by a computer and the data they generate are stored. Hard disks are much faster in use than floppy disks and also hold much more information.
A solid, flat piece of metal with metal oxide coating that is used to store digital data on. Because of their higher density and their fast spinning, hard disks can store more data and retrieve it faster than floppy disks. Hard disks range in storage capacity from 1 to 12 GB.
A computer storage disk that is permanently placed inside the computer and which cannot be removed without taking the computer apart. The 3.5" hard plastic disks used to store information are floppy disks, not hard disks.
A storage device that is comprised of one or more rigid platters which data is stored on. These devices are hermetically sealed to prevent dust from contacting the disk surface and possibly damaging the disk. Data is stored on the magnetic media as tiny "flux" reversals of magnetic fields. These can be modified and read by electromagnetic heads that "float" on a thin layer of air as the disk rotates at high speed.
Generally, the internal storage device in a computer called "hard" to distinguish it from a soft, or floppy, disk. Hard disks hold more data and are faster than floppy disks. Sometimes they are called "fixed disks" because they are not removeable.
A mass data storage device which usually are placed inside but which could also be an external device placed next to a computer. The device holds large volumes of data and/or a number of software programmes.
A storage medium, consisting of a magnetically-sensitive metal alloy disk. Magnetic heads moving over the surface of the disk record and read back information. Hard disks are usually mounted in a sealed and enclosed package to exclude dust and other pollutants which could damage the surface or the read/write heads; this allows them to hold much more information than a Floppy Disk. Storage capacities for hard disks used in personal computers range from 800 Mb up beyond 16,000 Mb (16 Gb) and are still rising.
A magnetic disk capable of storing large quantities of data. Most hard disks reside permanently in their housings; removable hard disk cartridges are less common. Hard disks are the persistent storage memory found in computers, digital cameras and other electronic products. Data access is via a read/write head that moves mechanically across the hard disk surface.
A device containing one or more inflexible platters coated with material in which data can be recorded magnetically, together with their read/write heads, the head-positioning mechanism, and the spindle motor in a sealed case that protects against outside contaminants. The protected environment allows the head to fly 10 to 25 millionths of an inch above the surface of a platter rotating typically at 3600 to 7200 rpm; therefore, much more data can be stored and accessed much more quickly than on a floppy disk. Most hard disks contain from two to eight platters.
n. A mass storage medium for computers that is typically available as a fixed disk (such as the disks used in the system units of personal computers or in drives that are external to a personal computer) or a removable cartridge.
A hard disk is part of a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces. Today's computers typically come with a hard disk that contains 100's of billion's of bytes (gigabytes) of storage.
Medium for permanent storage of data. Magnetic platters, electronics and mechanics make up a hard disk. The platters are fixed to a spindle. On each side of a platter there is a read/write head. Each platter is divided in to tracks, which again is divided into sectors. A characteristic with hard disks is that the platters and the mechanics are in an airtight enclosure, and that the read/write heads do not touch the platters as long as the platters are rotating. See fly height .
a rigid disk sealed inside an airtight transport mechanism. Information stored may be accessed more rapidly than on floppy disks and far greater amounts of data may be stored. Often referred to as Winchester disks.
A storage device composed of a rigid platter or platters used for long term data storage. Hard disks hold much more information than diskettes, and are not usually user removable. By default, the hard disk is referred to as drive C.
One or more rigid magnetic disks rotating about a central axle with associated read/write heads and electronics, used to store data. Most hard disks are permanently connected to the drive fixed disks though there are also removable disks. High speed disks have an access time of 28 milliseconds or less, and low-speed disks run 65 milliseconds or more. The higher speed disks also transfer their data faster than the slower speed units. Each surface of each disk is divided into a number of evenly spaced concentric circular tracks. The set of all tracks at a given radius on all surfaces the tracks which can be accessed without moving the heads are known as a cylinder. Each track is divided into sectors. Disk drives are commonly characterised by the kind of interface used to connect to the computer, e.g. ATA, IDE, SCSI
The main data storage area of a computing device. The hard disk is typically where the computer's operating system and other software are permanently stored. Hard disks have a larger storage capacity and faster data retrieval capabilities than floppy disks.
A computer's main (and fastest and most convenient) storage for programs and data. Originally named to distinguish it from floppy disks. All PCs are fitted with hard disks, sometimes more than one. The first (or only) hard disk is usually called C: by the computer. The most popular hard disk format is called EIDE.
This is an internal storage "container" where you can store large amounts of information permanently on your computer. It can store large gigabytes of information. Information can be erased from the hard disk. It is a little like a "treasure chest" where you keep things that are important to you that you want to have for a long time...of course, you can empty it anytime you like
A magnetic storage disk, secured and hardwired inside the computer. A Hard Disk is usually the C: drive on Windows machines. PC's with a Hard Drive partitioned into several segments or with additional Hard Drives added, will have other letters associated with their Hard Drives, such as D, E, F etc. Windows attributes these drive letters automatically, and will place other removable media such as CD ROM's or Zip drives will at the end of the list: thus a PC with only one Hard Drive (C:) will find that Windows labels its CD ROM drive with a (D:) and a PC with two hard drives will have its CD ROM labelled (E:).
Commonly refers to a form of magnetic media that uses a hard metal disk to store data. Unlike its "floppy" counterparts, a hard disk can typically hold much more data and is much faster, but is non-removable, or "fixed" to your computer. This is typically where the computer’s operating system and other software is installed. The terms "hard disk" and "hard drive" are often used interchangeably since the disk and the drive are usually contained in the same unit.
A type of magnetic storage disk that uses stiff plastic platters spinning rapidly. Hard disks have greater capacity than floppy disks and the information can be moved into computer memory more rapidly.
A hard disk of Winchester is similar to that used for floppy disks but with rigid disks which are not removable and is permanently sealed. It can hold the equivalent 100 or more floppy disks. Furthermore, the information held on a hard disk can be accessed 10 times as fast as from a floppy disk.
A hard disk is a disk that is permanently mounted in a hard disk drive that is inside the computer cabinet. The user of the computer cannot remove the hard disk. Such a disk is faster and has a much greater capacity than a typical floppy disk. Most of the time, the hard disk is called drive C: although other letters may be used for hard disks that are accessed over a network.
The hard disk is a permanent, (fixed) storage medium for computer data based on a rotating disc with a magnetically, sensitive layer. Information can be written on this and read again using a read/write head. The information stored is erasable.
A rigid magnetic disk that is able to store many times more data than a floppy disk. Usually it cannot be removed from the disk drive that's located inside your PC. In most PCs the hard disk drive is called drive C:, whereas the floppy disk drive is called drive A: or B:. A hard disk drive can normally store several hundred million bytes (or characters) of information, whereas a floppy disk can only store one and a half million bytes. If you hear a clicking or whirring sound when you save a document, that's the hard disk working
This is where all the data in your computer is stored. It is where all your files and folders are physically located. 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. At Newista HarDisk are SCSI(10.000rpm) Raid0(make them works 2 x faster which can be tought 20k rpm Disks)
A disk inside the computer which stores data and code, sometimes used incorrectly to refer to a 3.5" floppy disk, but differs from a floppy in that it can store more information, and is generally not removable.(You can take a floppy disk out of the floppy drive). WWWebfx Home Page
Common digital storage component in a computer. For video use, hard disks need to have: 1) an access time of less than 10 milliseconds; 2) a sustained throughput (data transfer rate) of 3 Megabytes per second; and 3) a maximum time for housekeeping of 33 milliseconds.
A hard disk is a permanently enclosed storage device, which is used for the storage of the operating system, user files and programs on a computer. The hard disk is either mounted inside the computer or within a case for external drives.
A storage device inside a computer, generally designated as the C: drive. It cannot be seen without opening up the computer; however, usually a light on the front of a computer shows when the hard disk is being accessed.
This is a disk that is permanently connected to your computer, and has a much higher capacity and speed than a floppy disk. Its capacity is measured in megabytes, and can be divided into several partitions.
Normal computer disks are often called floppy disks, as the disk on which magnetic coating is deposited is far from rigid. A hard disk is a more sophisticated type where the disk is rigid, rotates continuously at high speed, and cannot be removed from the drive. The non - interchangeability of the disks is not a major drawback, as the capacity of a hard disk is typically equal to that of about 60 floppy disks. The point of a hard disk is that it gives very rapid access to vast amounts of data. An increasingly popular feature on up-market computers, and also to be found on some of the more recent sound samplers.
A hard disk (or hard drive) is internal hardware which stores and provides access to large amounts of information. Most new computers include an internal hard disk that contains several gigabytes of storage capacity.
Usually the main disk drive of a PC, the hard disk drive differs from floppy disks in that it cannot be easily removed. However, the size of the disk enables up to a few gigabytes of memory to be stored on it, and the accessing speed is far greater than that of floppy disks, Zip disks or even CD-ROMs.
A storage device that holds large amounts of data, usually in the range of hundreds to thousands of megabytes. Although usually internal to the computer, some types of hard disk devices are attached separately for use as supplemental disk space. "Hard disk" and "hard drive" often are used interchangeably but technically, hard drive refers to the mechanism that reads data from the disk.
A device, also called hard disk drive, that contains one or more inflexible platters coated with material in which data can be recorded magnetically with read/write heads. The hard disk exists in a sealed case that protects it and allows the head to fly 10 millionths to 25 millionths of an inch above the surface of a platter. Data can both be stored and accessed much more quickly than on a floppy disk.
An advanced, large capacity, storage system for microcomputers. Only just available (for a few dedicated music-computers), hard disks operate like floppy disks, but store four or more times the amount of information.
Hard disk is a term used interchangable with hard drive (both are derived from hard disk drive). Hard disks use hard, metal platters for storing magnetic charges that represent data. Because the charges that are used to store your data don't go away even after your file is deleted or formatted, it is necessary to use a program that overwrites or wipes your hard drive in order to truly erase your data.
The "file cabinet" of the machine. This is the memory that your computer will use to store the results from the programs (and to store those programs). Hard Disk is currently specified in Gigabytes (billions of characters). Single disk drives are currently from 6 Gigabytes to 40 Gigabytes, and you can usually have more than one disk drive in your computer (but, if this is your first computer, stick with just one drive).
A hard disk (commonly known as a HDD (hard disk drive) or hard drive(HD) and formerly known as a fixed disk) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
