STORAGE - Coggle Diagram

- - - - does not lose its contents even when the power off
    - - compared than memory which have little/limited space capacity
    - - compare to memory, storage have slower transfer rate than memory
- - - - Functions: a separate freestanding storage device that connects with a cable to a USB port or other port on a computer or mobile devices
    - - Functions: An internal hard drive is the primary storage device located inside a computer system. It usually contains pre-installed software applications, the operating system and other files. Most desktop computers have several internal hard drives, allowing them to provide greater data storage
  - - - Used mainly as video and data storage, holds over 7 times a CD's capacity
        
        types of DVD such as DVD-ROM, DVD-R, DVD-RW
    - - Functions
        
        A type of optical disc used to store high- definition
        
        and ultra high-definition videos and movies.
        
        • It uses a blue laser instead of a red laser to read
        
        and write data on the disc.
        
        • Allow for six times more storage than a DVD.
      - types of BD
        
        BD-RE
        
        BD-R
        
        BD-ROM
    - - A type of optical disc used to store data, song, driver and program files
        
        Types of CD:
        
        CD-R
        
        Users can write in SEPARATE TIME but not erase
        
        CD-RW
        
        Users read and write on MULTIPLE TIME, erasable
        
        CD-ROM
        
        Users can read but cannot write/record or erase
- - - - 3) USB Flash Drives
        
        flash memory storage that users plug in a USB port on computers or mobile devices
      - 4) Memory Cards
        
        flash memory that users insert and remove from a slot in personal computers, smartphone, digital camera, or card reader/writer.
        
        examples: CompactFlash, microSD, Memory Stick Micro
      - 2) Solid State Drive
        
        a storage device that uses flash memory to store data, instructions and information
        
        characteristics: contains no moving parts, have storage capacity up to 8 TB
        
        BENEFITS and DRAWBACKS
        
        more durable and shock resistance
        
        use less energy
        
        faster transfer rates
        
        COST is much higher
        
        faster access time
      - 5)Optical Disks
        
        FUNCTIONS:
        
        Stores data in deformities on the surface of a circular
        
        disc and reads this data by illuminating the surface with
        
        a laser diode and observing the reflection.
        
        Primarily used to store software, data, digital photos, movies and music
      - 1) Hard disks
        
        storage device that: contains one or more inflexible, circulars patters that use magnetic particles to store data, instructions, and information.
        
        characteristics: high capacity storage, components enclosed in airtight, sealed case for protection.
