RAM Full Form

What is the Full form of RAM?

The full form of RAM is Random Access Memory. To write & read into storage, RAM has been used. RAM preserves files & programme data that the CPU is running. As data is lost when power is switched off, it is a volatile memory. RAM can be further subdivided into two categories

  1. SRAM (Static RAM)
  2. DRAM (Dynamic RAM)

A brief history of RAM

  • The Williams tube was used in 1947 to produce the first type of RAM.
  • The CRT (Cathode Ray Tube) was used and information was stored on the face of the tube in the form of electrical charge spots.
  • Magnetic-core memory has been used as a second commonly used type of RAM afterwards in the same year, 1947.
  • Many patents were on the title of Frederick Viehe, who was responsible with much of the development work.
  • For dealing with Magnetic-core memory, small metal rings & wires connecting to every ring have been used. One bit of data has been preserved in every one of those rings and that data can be retrieved at any moment.
  • However, in 1968, Robert Dennard initially discovered RAM, that is now known as solid-state memory. Transistors have been used to preserve bits of information in DRAMs.

Benefits of RAM

  • RAM does not include a mechanical moving component, so no noise is generated.
  • RAM requires far less power than a mechanical disc drive. It lowers emissions of CO2 and prolongs battery life.
  • RAM is considered to be the quickest medium of storage.

Limitations of RAM

  • Unless there is a power recovery system like a laptop battery, the power outage can induce irrecoverable loss of data.
  • The price of RAM per bit is huge, so devices don’t include much of it.
