What is RAM ?

According to the structure of the computer, memory is that part of the computer that stores data and process data input by the user, data in memory, information, and during the program process. It is present and is available immediately when required. It is also called primary memory or main memory. Primary memory is of two types RAM i.e. Random Access Memory and ROM i.e. Read Only Memory Here we are going to know about RAM i.e. Random Access Memory –

Random Access Memory (RAM) –
This memory is also called the temporary memory of the computer, no data is stored in it, as long as the computer is turned on, the data or program is temporarily stored in the RAM and the computer processor uses this memory to get the required data. Uses data and as soon as you shut down the computer, all the data gets deleted, so it is (RAM) also called Volatile Memory.

What are the types of RAM?

There are three types of RAM –
• Dynamic RAM
• Synchronous RAM
• Static RAM

Let’s know about them briefly-

• Dynamic RAM

This is known as DRAM, data in DRAM is stored in a memory cell, each memory cell consists of a transistor and a capacitor, in which a small amount of data is stored but after about 4 milliseconds the memory cell is transferred to the controller memory. Keep refreshing Refresh means that they rewrite data, so DRAM is much slower, but it consumes less power than other memory and does not deteriorate for a long time.

• Synchronous RAM

Synchronous RAM is faster than DRAM because it refreshes faster than DRAM Synchronous RAM refreshes with CPU clock speed, so it can transfer data faster.

• Static RAM

This is known as SRAM, Static RAM is less refreshed but it is able to keep the data in memory for a longer time, it stores the data as long as the system keeps getting current, it is able to store the data very fast. Accesses Static RAM, the data store remains until it is refreshed, it is also called Cache RAM.
