Alternatively referred to as main memory, primary memory, or system memory, RAM (random-access memory) is a hardware an equipment that enables information to it is in stored and also retrieved ~ above a computer. Ram is usually linked with DRAM, i beg your pardon is a type of memory module. Since data is accessed randomly instead of sequentially prefer it is top top a CD or difficult drive, accessibility times are much faster. However, uneven ROM, lamb is a volatile memory and requires strength to keep the data accessible. If the computer system is turned off, all data had in ram is lost.

You are watching: Ram is often referred to as ____ memory.


New users regularly confuse RAM with disk journey space. See our memory an interpretation for a comparison between the two.

Types that RAM

Over the evolution of the computer, there have been different variations the RAM. Several of the more common examples are DIMM, RIMM, SIMM, SO-DIMM, and also SOO-RIMM. Below is an example image the a 512 MB DIMM computer system memory module, a item of RAM uncovered in older desktop computers. This memory module would certainly be set up into among the memory slot on a motherboard.


Additional lamb information

As the computer boots, parts of the operation system and also drivers are loaded right into memory, which allows the CPU to process instructions faster and speed increase the boot process. After ~ the operating system is loaded, programs you open up like the internet browser you"re using to watch this web page are likewise loaded right into memory. If too many programs space open, the computer system swaps the data in the memory between the RAM and the difficult disk drive.

A computer"s power is greatly attributed come the quantity of memory had within it. If a computer does not have the recommended memory to run the operation system and its programs, it results in slow performance. The more memory a computer has, the more information and software it have the right to load and procedure quickly.

What"s the largest stick that RAM?

Currently, the largest solitary stick of ram is 128 GB.

History the RAM

The first form of lamb came about in 1947 v the usage of the Williams tube. It used a CRT (cathode beam tube); the data was stored on the challenge as electrically fee spots.

The 2nd widely used kind of lamb was magnetic-core memory, invented in 1947. Frederick Viehe is credited with lot of the work, having filed for numerous patents relating to the design. Magnetic-core storage works through the usage of tiny metal rings and also wires connecting to every ring. One little bit of data can be stored per ring and also accessed at any type of time.

However, RAM, as we recognize it today, together solid-state memory, was first invented in 1968 through Robert Dennard. Well-known specifically as dynamic random-access memory, or DRAM, transistors were provided to store bits of data.
