Final answer:
The 'Standby' section in the Physical Memory section of Resource Monitor displays memory that is still linked to a process but can be repurposed for other processes.
Step-by-step explanation:
In the Physical Memory section of the Resource Monitor, the specific memory allocation section that displays memory still linked to a process but available for reuse is called 'Standby'. The Standby list contains caches for programs and files, which includes memory that was once assigned to a process but is now free and can be reallocated to another process. This memory is effectively available, although still technically in use because it holds data that may be read again by the process. If the process needs the data again, it can quickly retrieve it from the Standby list without having to read from the disk. However, if another process needs memory and none is free, the system can repurpose memory from the Standby list. This allows the system to efficiently manage physical memory and ensure responsiveness.
