What is primary memory? explain its types?
please ans my question...
Answers
Answer:
Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location.
There are four types of primary storage:
read only memory (ROM)
random access memory (RAM)
flash memory.
cache memory.
Hope this is helpful.
Answer:
Primary memory is a segment of computer memory that can be accessed directly by the processor.
1.RAM is short for “random access memory” and while it might sound mysterious, RAM is one of the most fundamental elements of computing. RAM is the super-fast and temporary data storage space that a computer needs to access right now or in the next few movements.
2.ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
3.Flash memory is a long-life and non-volatile storage chip that is widely used in embedded systems. It can keep stored data and information even when the power is off. It can be electrically erased and reprogrammed. Flash memory was developed from EEPROM (electronically erasable programmable read-only memory).
4.Cache memory is a type of fast, relatively small memory that is stored on computer hardware. ... The purpose of cache memory is to store program instructions that are frequently used by software during its general operations, this is why fast access is needed as it helps to keep the program running quickly.
