The correct answer is A. SIMM.
A SIMM (Single In-Line Memory Module) is a type of memory module that was used in personal computers in the 1980s and 1990s. SIMMs are made up of a number of memory chips that are mounted on a small circuit board. The circuit board has a number of pins that connect to the motherboard of the computer. SIMMs are typically used to expand the amount of memory in a computer.
A SILMM (Single In-Line Memory Module with Staggered Pins) is a type of SIMM that was developed to address some of the limitations of earlier SIMMs. SILMMs have pins that are staggered, which allows them to be installed in pairs in a computer. This allows for a higher density of memory to be installed in a computer.
SM (System Memory) is a general term for the memory that is used by the operating system and applications on a computer. SM can be either volatile or non-volatile. Volatile memory is lost when the power is turned off, while non-volatile memory is not.
SMM (System Management Mode) is a mode of operation for the CPU that allows it to perform certain tasks without having to interact with the operating system. SMM is used for tasks such as power management and security.
None of the above is the correct answer to the question “What is the acronym for Single In-Line Memory Module?”
