Floppy disks use magnetic disk to store the data.
true
The use of a HP recovery disk is to reset a computer system to a former condition. This could be useful if the computer system is infected by viruses.
A disk drive is a device that computers can use to read and write information on computer disk. An example of one is the hard disk drive.
The role of a disk drive is to store (write) and retrieve (read) digital information for a computer system. Storage may be either on magnetic disks (Hard Disk Drive - HDD), in semiconductors (Solid State Drives - SSD), or it may use a combination of magnetic disks and semiconductors (Hybrid Hard Disk Drive - HHDD). In all cases, data is retained even when power is removed (non-volatile). Disk drives are located in the Secondary Tier of storage, that is they are not directly accessible to the computer (Primary Tier) but are accessed through an interface such as SCSI, ATA, or USB
Hard disk drives use a magnetic coating of iron oxide to store data because it can be easily magnetized to represent binary data (0s and 1s). The magnetic polarity of the iron oxide particles can be changed by a magnetic head, allowing data to be written and read from the disk.
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.
UNIVAC I
Not normally. The restore disk is specific for the hardware in the computer system it came with.
They either use a rescue disk or they insert the hard disk into another computer as a secondary drive.
When you are prepared to lose every piece of information on the disk. When the disk is not formatted. When you want to switch to or from a disk that is formatted for a Macintosh computer. Etc.
