  software that enables storage of data

  hardware that acts as RAM and temporarily holds information

  a sequence of binary bits that stores data as bits

  a piece of computer equipment on which information can be stored.

 2. Developments in the field of storage are progressing every day. There is talk of 'embedded storage chips' becoming common place. Can you name one more type of storage that is not on the below list.

 4. Three types of storage we commonly look at are 1. Optical 2. Magnetic and 3. Solid State. What would you use for storing images in a digital camera and why?

  None of these options would be suitable for a digital camera.

  Solid State - because it is not affected by the camera moving around a lot

  Magnetic - because it has a very large capacity

  Optical (DVD/CD) - because it is cheap and portable and can be read by most computers

 5. Most computer systems require secondary storage (this is different from Main Memory and RAM) in order to store files (like the operating system) even when the system is 'off'. This is referred to as ____________.
