Optical disc storage is non-volatile and sequential access (ex cd, dvd) types of storage devices (cont) usb flash drive- a nand-type flash memory storage device integrated with a usb (universal serial bus) interface flash memory stores information in an array of floating gate transistors, called cells each cell stores. Optical disk drives were bulky and they consumed a lot of power removing optical drives lead the way to making devices without moving parts, as moving parts have a higher failure rate flash drives came about and offered a high- speed, multiple-use and higher capacity storage mechanism which was so. While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity, such as usb flash drives, flash storage cards, portable external hard disk drives, optical discs, rom cartridges and storage available. Explain the need for secondary storage describe common storage technologies such as optical, magnetic and solid state select suitable storage devices and for a drive to read data from a disk, the read/write head must move sideways to align with the correct track (the time to do this is called the seek time) and then wait. A floppy disk is a type of data storage that is composed of a disk of thin, flexible(“ floppy”) magnetic storage medium encased in a square or rectangular plastic shell floppy disks are read and written by a floppy disk drive floppy disks are a dying and being replaced by the optical and flash drives many new computers do. From helium hard drives to dna digital storage, here's what the future of data storage technology might look like besides the space savings, dna is ideal for long-term storage: while you're lucky if your hard drive lasts four years and optical disks are susceptible to heat and humidity, lead harvard.
In computing, external storage comprises devices that store information outside a computer such devices may be permanently attached to the computer, may be removable or may use removable media contents [hide] 1 types of external storage 11 magnetic storage 12 optical storage 121 cd 122 dvd 123 blu -. First, i will be explaining flash drives flash drives are a data storage device that includes flash memory with an integrated universal serial bus (usb) interface ( wikipedia) [tags: technology, data, transfer] :: 6 works cited, 794 words (23 pages), strong essays, [preview] · flash drives and optical storage - flash drives. Usb flash drives ultimately proved to be the most popular rewritable storage medium among the general public due to the near-ubiquity of usb ports on personal computers and soon after because of the far greater storage sizes offered zip drives fell out of favor for mass portable storage during the early 2000s the zip. A flash drive is a small storage device that is used to save and/or transport files from one computer to another data stored on flash drives is impervious to scratches, dust, magnetic fields and mechanical shock this makes them suitable for transporting data conveniently without risk of damage.
The optical disk drive used for dvds, cds, and blu-rays, is one commonly used piece of hardware that has replaced the floppy drive usb floppy disk drives interface with the computer over a usb port and function much like any other removable storage device, like external hard drives and flash drives. Describe the proper handling and storage techniques of disks, cds, cdr's, dvds, flash/usb drives, and other equivalent optical media devices 3 explain the difference between read-only d internet safety hardware/software 8 write a 250-word essay or give a three-minute oral report about the history of computers.
Not all of it needs to be stored, but manufacturers of data storage aren't making hard drives and flash chips fast enough to hold what we do want to keep traditional media like hard drives, thumb drives or dvds store digital data by changing either the magnetic, electrical or optical properties of a material. It is undeniable that hard disk storage capacities have by far outrun gains in performance, which is why the hard drive remains the most noticeable bottleneck in modern pcs as soon as you the best compromise may be a combination of flash and magnetic memory - so-called hybrids this technology. A usb flash drive -- also known as a usb stick, usb thumb drive or pen drive -- is a plug-and-play portable storage device that uses flash memory and is lightweight enough to attach to a keychain a usb flash drive can be used in place of a compact disc when a user plugs the flash memory device into the usb port, the. The external hard drive has a much higher storage size to price ratio, is not significantly larger in physical size, and it can be as durable as a flash drive if it is of the solid state design however, the disc drive (if equipped) is susceptible to magnetic fields and impact this type of drive is probably best used as a computer.
Flash drives, also known as usb drives or jump drives, contain mini circuit boards with memory chips to save and retain your data and information there are no moving parts, and separate media is not necessary to read or record data this type of storage media is called solid state memory, and differs from optical and. Magnetic storage and magnetic recording are the term that refer to the storage of data on a magnetized medium similar technology) in the case of magnetic discs (eg floppy disc or hard-drive), the dots are arranged in circles on the surface of a plastic, metal or glass disc that has a magnetisable coating. The disk drive senses direction of flow and data is sent from the head into memory magnetic disks diskette drives and hard disk drives are the most commonly used storage devices in pcs both fall into the magnetic storage category because they record data as magnetic fields fundamental differences and similarities.
