One of a series of parallel magnetic recording disks in a drive unit, used for the recording and retrieval of digital information; used especially in personal computers
A hard disk is a magnetic storage device consisting of multiple spinning platters (disks), each with its own read/write heads Hard disk drives have a much higher storage capacity (up to a gigabyte or more) than floppy disks They also have a much faster access time and higher transfer rate than floppy disk drives The access times of hard disks are as low as 5 to 20 milliseconds (ms); floppy disk access times are 200 msec or more Hard disks differ from each other (and from floppy disk drives) in the interfaces and formats encoding techniques and rules) used
A disk drive which contains one or more disks (which are hard platters rather than floppy disks) permanently sealed in it Hard disks are noted for their speed and high capacity
Your computer's hard disk is the part of your computer where you store your document files and programme files Disks are sometimes referred to as 'disk drives' It is similar to a floppy disk but has a much greater capacity and works a lot faster Typically on a Windows PC it will have the drive letter C and your floppy disks will use drive A
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 3 Gb and 12 Gb in storage capacity
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
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-ROM's
The main device that a computer uses to store information Hard disks are rigid aluminum or glass disks about 3 5" in diameter in a personal computer, and smaller in a laptop They are coated with ferromagnetic material and rotate around a central axle Data is transferred magnetically by a read/write head A hard disk drive for a personal computer may contain as many as eight hard disks, rotating around the same axle Most hard disks are permanently connected to the drive, but there are removable hard disks Hard disk access time (the amount of time it takes to retrieve data) is measured in milliseconds
(n ) A magnetic disk that stores data Usually a fixed disk, permanently sealed in the drive, though possibly a removable hard disk A hard disk can store more than 10 Gbytes of data Access time is much faster than soft (floppy) disks The head that reads the data floats over the hard disk's surface, while the head of the floppy disk touches the disk's surface while reading or writing data See also disk
A peripheral data storage device that may be found inside a desktop or laptop as in a hard drive situation The hard disk may also be a transportable version and attached to a desktop or laptop
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 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
A computer's hard disk is a stiff magnetic disk on which data and programs can be stored. A rigid magnetic disk fixed permanently within a drive unit and used for storing computer data. Hard disks generally offer more storage and quicker access to data than floppy disks do. a stiff disk inside a computer that is used for storing information floppy disk. Magnetic storage medium for a microcomputer. Hard disks are flat, circular plates made of aluminum or glass and coated with a magnetic material. Hard disks for personal computers can store up to several gigabytes (billions of bytes) of information. Data are stored on their surfaces in concentric tracks. A small electromagnet, called a magnetic head, writes a binary digit (1 or 0) by magnetizing tiny spots on the spinning disk in different directions and reads digits by detecting the magnetization direction of the spots. A computer's hard drive is a device consisting of several hard disks, read/write heads, a drive motor to spin the disks, and a small amount of circuitry, all sealed in a metal case to protect the disks from dust. In addition to referring to the disks themselves, the term hard disk is also used to refer to the whole hard drive
A flat, circular, rigid plate with a magnetizable surface on one or both sides of which data can be stored Note: A hard disk is distinguished from a diskette by virtue of the fact that it is rigid Early in the development of computer technology, hard disks, often multiple disks mounted on a common spindle, were interchangeable and removable from their drives, which were separate from the processor chassis This technology is still in use, especially in conjunction with large mainframe computers, but physically smaller computers use hard disks that are in sealed units, along with their control electronics and read/write heads The sealed units are usually installed permanently in the same chassis that contains the processor
A high capacity storage device that a computer uses for programs and data, measured in megabytes or gigabytes Information held on a hard disk is safe when the power is withdrawn
A magnetic disk storage device used on larger microcomputers Hard disks are similar to the disk storage on mainframes, and are permanently installed in the micro
magnetic storage device consisting of 1 to 4 metal platters which are sealed inside a case Usually installed inside the computer's case, though there are removable and cartridge types
These disks are larger in capacity than floppy disks and also faster Do not store your files on the hard disks (C drive) on the university computers from one session to another- they will be deleted! Use the M drive instead (see below)
A physically rigid magnetic storage disk Hard disks have much greater data capacity (40 MB to 40 GB) and are much faster to use than floppy disks ``Zip'' disks are actually hard disks (hence their speed and capacity), but have the convenient portability of floppy disks
