Types of Computer Memory (RAM and ROM)

Memory is the most fundamental component of a processing framework in light of the fact that without it computer can't perform basic undertakings. Computer memory is of two fundamental sort – Primary memory/Volatile memory and Secondary memory/non-unpredictable memory. Arbitrary Access Memory (RAM) is unstable memory and Read Only Memory (ROM) is non-unpredictable memory.

1. Random Access Memory (RAM) – 

• It is additionally called as perused compose memory or the principle memory or the essential memory. 
• The programs and information that the CPU requires during execution of a program are put away in this memory. 
• It is an unstable memory as the information loses when the power is killed. 
• RAM is additionally grouped into two sorts SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory). 

2. Read Only Memory (ROM) – 

Stores urgent data fundamental to work the framework, similar to the program basic to boot the computer.

• It isn't unstable. 
• Continuously holds its information. 
• Utilized in implanted frameworks or where the programming needs no change. 
• Utilized in number crunchers and fringe gadgets. 
• ROM is additionally ordered into 4 types-ROM, PROM, EPROM, and EEPROM. 

Sorts of Read Only Memory (ROM) – 

PROM (Programmable read-just memory) – It can be programmed by client. Once programmed, the information and directions in it can't be changed.

EPROM (Erasable Programmable read just memory) – It can be reprogrammed. To eradicate information from it, open it to ultra violet light. To reprogram it, eradicate all the past information.

EEPROM (Electrically erasable programmable read just memory) – The information can be eradicated by applying electric field, no need of ultra violet light. We can delete just segments of the chip.
