In a photo editing program a picture file is loaded into ram, but there may be multiple processes that all do work on the picture (for example when a blur is applied to the picture). Since high resolution images consume a significant amount of memory, this program would need to rely on shared memory. In such a system, explain why might it become an issue if multiple processes are accessing the same memory at the same time

When a program uses multiple memory of a system the system will respond slower. There should be enough RAM which can support the high resolution graphics. If the RAM storage is enough it will run the software smoothly but if RAM storage is not supporting the software there will be lags while software runs.

Explanation:

The software run through RAM and memory of a system. If there is high resolution graphics involved to run a program then there is a separate graphic card required for many software's. These software uses high memory which creates burden on RAM which introduces lags and pauses while the software is running.
