The most important advantage of disk storage over tape storage?
disk storage-> direct data access storage tape storage -> serial data access storage
What is the purpose of a tape streamer?
the purpose of tape streamer is that to store data on a magnetic tape by the hard disk p.s it is the only purpose of streamer,,,
What are the advantages of disk to disk backup?
There are advantages of back-up to disk technology. It is four times faster than tape backup, data can be compressed so that more data can be stored in less space, data can be recovered faster in the even of a disaster, and finally it is much more reliable than tape backup.
What is a storage device that stores data permanently?
The following device are used to store data permanently.These are Hard Disk Drive(HDD),Compact Disc(CD/DVD),Floppy Disk,Zip and Tape.
Difference between hard drive and magnetic tape?
A hard drive comes with the Computer. A hard drive is considered permanent as opposed to magnetic tape. The data in tape can be accessed only serially whereas randomly in hard drive.
What is the difference between a disk and tape in dbms?
In a DBMS, a disk is a permanent storage medium that provides fast random access to data, suitable for storing the primary database files. On the other hand, tape is a sequential storage medium that is typically slower and used for backup and archival purposes due to its lower access speed compared to disks. Tapes are often used for long-term storage of data that doesn't need to be accessed frequently.
How data is organized on a magnetic tape disk?
1. When data is recorded onto magnetic tape, it is written in blocks with inter-block gaps between them. The rate at which data is written or read determines how the tape drives will have to cope with the rate at which data goes on and off the tape as well as the rate at which data is supplied to or demanded from the host.
Which of the following storage media used laser technology to store data Floppy disk Magnetic tape CD-ROM Hard drive?
Of these only CD-ROMs use LASERs to access the data. The others are magnetic storage devices.
Write a short note on magnetic disk?
Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drive.
What is magnetic disk storage capacity?
Tape remains a viable alternative to disk in some situations due to its lower cost per bit. This is a large advantage when dealing with large amounts of data. Though the areal density of tape is lower than for disk drives, the available surface area on a tape is far greater. The highest capacity tape media are generally on the same order as the largest available disk drives (about 5 TB in 2011). Tape has historically offered enough advantage in cost over disk storage to make it a viable product, particularly for backup, where media removability is necessary.
What is the Difference between hard disk and cassette tape?
what is the defference between cassette tape and hard disk
Which two storage devices use a magnetic medium for storing data?
Tape drive and hard disk drive
