What Is Primary Memory in English-प्राइमरी मेमोरी क्‍या होती है

According to the structure of the computer, memory is that part of the computer that stores the data and process data inputted by the user, data, information, and programs in memory are present during the process and available immediately when needed. It is also called Primary Memory or Main Memory. Let's know more about Primary Memory -

What Is Primary Memory in English-प्राइमरी मेमोरी क्‍या होती है 
There are two types of primary memory -
1. RAM  means Random Access Memory
2. ROM means Read Only Memory
1- Random Access Memory-रैम
This memory is also called as temporary memory of the computer. There is no data store in it. As long as the computer is on, the data or program is stored temporarily in RAM and the computer processor can use this to get the required data. Uses data and all the data gets deleted as soon as you shut down the computer, so do this RAM (Volatile Memory)
What is the type of RAM
There are three types of RAM -
1.1. Dynamic RAM
1.2. Synchronous RAM
1.3. Static RAM
1.1- Dynamic RAM-डायनेमिक रैम 
This is known as DRAM, the DRAM has a data memory cell store, each memory cell consists of a transistor and a capacitor, with a small amount of data stored, but about 4 seconds later the memory cell controls the memory. Refresh Refresh means that they rewrite the data, so DRAM is much slower, but it is less power than other memory Eats and is not bad for a long time.
1.2- Synchronous RAM-सिंक्रोनस रैम 
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.
1.3- Static RAM-स्‍टैटिक रैम
It is known as SRAM, Static RAM is less refreshed but it keeps the data in memory for longer, it stores the data as long as the system gets the current it very fast. Static RAM accesses the data store until it is refreshed, it is also called Cache Ram, what is cache memory.

2- Read Only Memory-रोम 
It is a temporary memory ROM's full name is read only memory, the data or programs that are inserted while preparing it are not finished even after the computer is switched off, the data stored in ROM is not destroyed. also called volatile memory.
What is the type of ROM ?
There are three types of ROMs -
2.1 PROM (Programmable Read Only Memory)
2.2 EPROM (Erasable Programmable Read Only Memory)
2.3 EEPROM (Electrical Programmable Read Only Memory)
2.1- PROM (Programmable Read Only Memory)
PROM means programmable read only memory can be stored only once, ie it cannot be erased and cannot be changed.
2.2- EPROM (Erasable Programmable Read Only Memory)
The full name of EPROM is Erasable Programmable Read Only Memory, it is similar to PROM but the program stored in it can be erased only by ultraviolet rays and new programs are stored. Can be done.
2.3- EEPROM (Electrical Erasible Programmable Read Only Memory)
The full name of EEPROM is Electrical Erasible Programmable Read Only Memory, a new technology is also EEPROM, in which programs can be erased from memory by method.
Summary Words
1. Storing any instructions, information, or results is called memory.
2. Memory is an integral part of C.P.U, it is also called Computer's Main Memory, Internal Memory, or Primary Memory.
3. The full form of RAM is random access memory.
4. Random access memory is a temporary memory of a computer.
5. Full form read of ROM is read only memory.
