a File
A collection of records on a particular topic that is stored is called a database. A database is an organized collection of data that can be easily accessed, managed, and updated.
A database designer is a person who specifies how a database records are stored, accessed and related to make sure there is adequate performance!
It is stored as magnetic impulses, similar to how a tape recorder records, except that the data is digital rather than analog.
An organized collection of related records is called a database. It is a structured set of data stored in a computer system that can be easily accessed, managed, and updated.
A write head is the part of an electromechanical device which converts electrical signals into digital or analogue information stored on a magnetic or optical medium.
No. Floppy disks are magnetic media that rely on magnetic polarization to write data to the disk much like a hard drive. Unlike CD media they can be erased by a strong magnet field that effectively scrambles the data tracks.
A conventional hard disk is magnetic.
optical memory: it is a memry device that uses laser beams ro store data . for e.g. CDROM. magnetic memory: it is a memory device that uses magnetic tape to store data . for e.g. hard disk optical memory are advanced and faster than magnetic memory device..
the difference is that sequential organization: this are records are stored and accessed in a particular order sorted using a key field serial organisation: records in a file are stored one after another. You need to go first file in order to reach the required file.
Memory cards are flash storage, where data is stored in discrete transistor cells that can normally be erased or changed several thousand times.
