RAM Modules

RAM (Random Access Memory) modules, also known as memory modules or memory sticks, are essential components of computer systems, providing temporary storage for data and program instructions that the CPU needs to access quickly. RAM modules are composed of semiconductor memory chips mounted on a printed circuit board (PCB). They come in various form factors, such as DIMM (Dual In-Line Memory Module) and SO-DIMM (Small Outline Dual In-Line Memory Module), and different types, including DDR (Double Data Rate), DDR2, DDR3, and DDR4, each offering different data transfer rates and capacities. RAM modules play a crucial role in system performance, affecting tasks such as multitasking, gaming, and multimedia editing.
