Study Notes
Storage Devices
- A device used by businesses to back up and archive large amounts of data uses Magnetic Storage.
- A device used to store videos, allowing for better graphics and greater resolution photos, uses Optical Storage.
- A type of storage device that is becoming obsolete because it's not big enough to store one song or high-resolution photo is Floppy Disk, which uses Magnetic Storage.
- Devices used for storing data in digital cameras and some mobile phones, MP3 players, and video game consoles use Electronic Storage.
- A Hard Drive, located inside the computer's system unit, uses Magnetic Storage.
- A device used to store music and some documents, with its own case and sitting outside of the computer's system unit, is a Hard Drive, which uses Magnetic Storage.
- A small storage device that you plug into a USB port, easy to carry around, is a Flash Drive, which uses Electronic Storage.
CD Types
- A CD-R (CD-Recordable) is a CD that you can burn to only one time and thereafter it is read-only.
- A CD-ROM (CD-Read Only Memory) is a CD that you will never burn to because it contains music or software.
- A CD-RW (CD-ReWritable) is a CD that you can burn to many times until it is full.
Computer Memory
- ROM (Read-Only Memory) contains instructions needed for the computer to boot.
- Non-Volatile means that data is not erased when the power is turned off.
- RAM (Random Access Memory) stores data while you are processing it.
Computer Storage
- CDs and DVDs store data optically.
- Hard Drives and Floppy Disks store data magnetically.
Storage Capacity
- The cost of flash drives varies based on its storage capacity.
- CDs are primarily used for storing video and photos.
Task-Based Storage
- Hard Drive is used for storing the software that runs on a desktop computer.
- CD is used for storing the latest chart-topping music album of a rap group.
- Flash Drive is used for transferring a 2-page report from school to home.
- Hard Drive or DVD is used for storing a video.
- Hard Drive is used for storing a back-up copy of the data on a school's network.
- Flash Drive or Memory Card is used for storing photos from a digital camera.
Storage Capacity Size
- Floppy Disk has the smallest storage capacity.
- Flash Drive has a larger storage capacity than Floppy Disk.
- CD has a larger storage capacity than Flash Drive.
- DVD has a larger storage capacity than CD.

Computer Memory and Storage
- RAM is the memory in the computer that holds data as you manipulate (process) it.
- ROM is the memory in the computer that contains instructions used when it ‘boots up.’
- Cache is the area in the computer that temporarily holds data waiting to be processed.
- Storage is the place where data is held while you are not processing it.
- The three kinds of storage are: Magnetic, Optical, and Electronic.
- Optical Storage is the use of low-powered lasers to save (burn) and read data from CDs and DVDs.
- Electronic Storage is the use of a chip to electronically save, erase, or reprogram data.
- Magnetic Storage is a means of recording data onto disks or tape by magnetizing particles.
