What is the role of memory in CPS nodes?

Memory plays a critical role in Cyber-Physical Systems (CPS) nodes by serving as the primary component responsible for storing data and programs. In a CPS node, memory allows the system to hold the instructions needed to execute tasks and retain data collected from various sensors or inputs. This stored information is essential for the node to perform computations, make decisions, and respond to its environment accurately.

Without memory, the CPS nodes would lack the ability to retain essential information needed for processing and execution, fundamentally limiting their functionality. Therefore, the storage capacity of memory directly influences the performance and capabilities of a CPS node, enabling it to not only run algorithms but also to access historical data for analysis and decision-making.

In contrast, executing programs is more about the processor's role rather than memory. Generating energy pertains to energy sources and management rather than memory's function, and increasing communication range relates to the network capabilities rather than storage. Thus, the focus on memory's role in storing data and programs is vital in understanding the overall architecture and operation of CPS nodes.
