- an individual memory chip that has dual rows of pins used to attach it to the motherboard
-
Explanation & Hints: A SIMM (Single In-line Memory Module) is a type of memory module used in computers. Here are some details about its characteristics:
- Small Circuit Board: A SIMM consists of a small, thin circuit board that holds multiple memory chips. These chips are used to store data temporarily for processing by the computer’s CPU.
- 30- or 72-Pin Configuration: SIMMs come in two main types based on the number of pins they have. The older type has 30 pins, while the more common type, used in later computer systems, has 72 pins. These pins are used to connect the SIMM to the computer’s motherboard.
- Dual In-line Design: Unlike newer memory modules (like DIMMs) that have separate electrical contacts on each side of the module, a SIMM has a single set of contacts that are shared on both sides of the module. This means that each side of the connector has identical pins.
- Early Memory Module: SIMMs were widely used in the 1980s and 1990s before being replaced by DIMMs (Dual In-line Memory Modules), which have more pins and can provide higher data transfer rates.
SIMMs provided a way to increase the memory capacity of computers at the time by allowing users to add multiple memory modules to their systems, thereby enhancing the computer’s performance and ability to run more complex applications.
