RAM Full Form : Random Access Memory ( RAM ) is a term frequently encountered in computer science, electronics, and technology. RAM plays a crucial role in the speed and efficiency of computers, mobile devices, and modern digital systems. RAM stands for Random Access Memory, a type of computer memory that can store and retrieve data quickly. Learn about the history of RAM , its types (SRAM and DRAM), its advantages and disadvantages, and more. This post introduces all RAM types to you, including SRAM, DRAM, SDRAM, DDR SDRAM, and RDRAM. SRAM and DRAM are two types of RAMs. SRAM i.e., static RAM is RAM in which data is stored in transistors in the form of voltage. DRAM i.e., dynamic RAM is RAM in which data is stored in capacitors in the form of electric charges. The SRAM is faster and expensive whereas DRAM is slower and less expensive. SRAM is used as cache memory whereas DRAM is used as main memory in computer systems. In this article, we will explore the difference between static RAM and dynamic RAM .
