What are the parameters used to characterize memory technologies? Explain the terms.

Solution

There are four major storage levels:

   Internal – Processor registers and cache.
   Main – the system RAM and controller cards.
   On-line mass storage – Secondary storage or Disk Storage
   Off-line bulk storage – Tertiary and Off-line storage.

Fiurther You can divide memory into two category:
   1.
       Volatile memory is computer memory that requires an active power connection to function. When the power to a volatile memory source is shut off, volatile memory loses its contents, and the information is deleted. The most common form of volatile memory used in computers today is random access memory, or RAM, various sticks of which are in the picture above. RAM is used to temporarily hold data that is required to run programs or applications on a computer or similar electronic device.

       The advantages of volatile memory are: it functions fast, and it is well-suited to protecting sensitive information. When the power source is shut down, the information is quickly deleted. Source: http://theydiffer.com/difference-between-volatile-and-non-volatile-memory

   2.
       Non-volatile memory is memory that does not require a connection to a power source to retain information. In other words, when the power source to which the memory is connected is shut off, the memory does not lose the information it has. Common examples of non-volatile memory are computer hard-disk drives, seen in the picture above, or flash drives. Hard-disk drives hold more long-term data such as files and documents. The advantage of non-volatile memory is longer-term retention of information. Source: http://theydiffer.com/difference-between-volatile-and-non-volatile-memory/
