Sc Page 5 storage will take these forms: Magnetic disk (Floppy disk, Hard disk drive) and Magnetic tape data storage. Without permanent or temporary storage, a computer wouldn’t function as expected. Chapter 3 storage media and devices 1. Backup storage refers to a storage device, medium or facility that is used for storing copies and instances of backup data. We can later come back to that place and get our data back again. These are compact disk (CD), digital versatile disk (DVD)and Blu-Ray disk (BD). Magnetic Storage Media. Fixed Hard Disk: Main backing storage device in computers. Sometimes the storage medium is a fixed (permanent) part of the storage device, e.g. Machine that reads/writes data to and from the media Optical media - such as the compact disk ( CD ) - are storage media that hold content in digital form and that are written and read by a laser ; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. 0% average accuracy. 4 minutes ago. serial/sequential, direct/random) and access speeds; In the case of magnetic tape the dots are arranged along the length of along plastic strip which has been coated with a magnetisable layer (audio and video tapes use a similar technology). Storage Devices and Media → Optical Storage Devices / Media; Why 'Optical'? WHAT IS DATA STORAGE? Save. The earliest form of removable media, punched cards and tapes, predates the electronic computer by centuries, with the Jacquard loom of 1801 using interlinked cards to control the machine. Backing storage – secondary storage, data stored permanently. They may be internal or external to a computer, server or computing device. 0. History. 2. Magnetic storage media and devices store data in the form of tinymagnetised dots.These dots are created, read and erased using magnetic fields created by very tiny electromagnets.

Pretty self-explanatory, the media makes use of the magnetic properties of certain materials and uses a special coating that let’s information be converted to 1s and 0s. # The term can also be used as a collective noun for the press or news reporting agencies. These devices store data in the form of magnetized dots created by electromagnets. Candidates should be able to: identify storage devices, their associated media and their uses, e.g. Optical storage devices save data as patterns of dots that can be read using light. magnetic backing storage media: fixed hard disks and drives, portable and removable hard disks, portable and removable hard drives, magnetic tape drives and magnetic tapes, memory cards optical backing storage media (CD/DVD/Blu-ray): CD ROM/DVD ROM, CD R/DVD R, CD RW/DVD… The device that saves data onto the storage medium, or reads data from it, is known as the storage device. alarm systems). However, storing your old data in bulk like this is a really bad idea. 0. Storage devices and media are in vast arrays of electrical devices found in homes, schools and work.

Optical media have a number of advantages over magnetic media such as the floppy disk. Optical storage media stores data on a disc as a number of data dots that can be read using light (usually a laser beam). Almost all optical storage involves the use of a 5" disk from which data is read by a laser. Because it is so slow, It is useless for real-time applications (where what is stored is constantly being updated). Each dot represents 1’s and 0’s (Bits of information). Types of Backing Storage: magnetic, optical, solid state. Edit. When we talk about ‘storing’ data, we mean putting the data in a known place.
