The correct answer is Read-Only Memory (ROM) ROM stands for Read-Only Memory. ROM is a storage device that is used with computers and other electronic devices. Data stored in ROM may only be read. ROM is used for firmware updates, which means It contains the basic instructions for what needs to happen when a computer is powered on. Firmware is also known as BIOS, or basic input/output system. ROM is non-volatile storage, which means the information is maintained even if the component loses power. ROM is located on a BIOS chip which is plugged into the motherboard. ROM plays a critical part in booting up or starting up, your computer. Important PointsTerminologiesCharacteristicsRandom Access Memory (RAM) This memory allows writing as well as reading of data, unlike ROM which does not allow writing of data on to it. It is volatile storage because the contents of RAM are lost when the power (computer) is turned off. If you want to store the data for later use, you have to transfer all the contents to a secondary storage device. Dynamic random access memory (DRAM)It is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function. DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs), workstations and servers. CacheCache primarily refers to a thing that is hidden or stored somewhere, or to the place where it is hidden. It has recently taken on another common meaning, €œshort-term computer memory where information is stored for easy retrieval. €
