Memory

Memory

1. RAM (Random-Access Memory)

   • When a program is loaded from a hard disk the data and instructions are stored here
   • Generally has less space but is faster than the hard disk
   • When power is lost all information in RAM is lost (it is volatile)

2. ROM (Read-Only Memory)

   • Cannot be edited or deleted
   • Stores information that will not need to be changed
   • Stores bootstrapping instructions (the initial steps for turning on)

3. Cache Memory

   • Stores copies of information from RAM that is used very frequently
   • Very quick memory
   • Very close to the CPU

4. Flash Memory

   • Uses electronic chips for storage
   • Non-volatile (information is not lost when there is no power)
   • Typically used with flash drives to transport information from one computer to another
