Computer RAM or random-access memory is one kind of computer memory that can be used indiscriminately. It acts as the main memory of the computer system. It allows accessing any byte without the interference to its prior bytes. It is mostly the common type of memory used in computer systems and sometimes in printers. Generally, two types of RAM are available, namely- DRAM or Dynamic random-access memory, and the other is SRAM or Static random-access memory.
DRAM is widely used because of its availability and cheap cost, while SRAM is relatively expensive but faster than DRAM. For DRAM, it is necessary to refresh the system continuously whereas, SRAM doesn’t require any refreshing. Moreover, the data transfer rate is faster in SRAM rather than DRAM. However, you should pick your desired RAM according to your budget.
