Final answer:
The disadvantages of invoking the detection algorithm for every request include overhead in computation time, consumption of memory, and delays in memory allocation, all contributing to system inefficiency.
Step-by-step explanation:
The question pertains to the disadvantages of frequently running a detection algorithm in the context of resource allocation in computer systems.
Invoking the detection algorithm for every request can lead to several disadvantages. These include considerable overhead in computation time, the significant consumption of memory, and longer time intervals for memory allocation requests to be processed. All of these factors can contribute to system inefficiency, as the algorithm consumes valuable system resources that could be used by other processes and tasks, likely leading to system bottlenecks and degraded performance.
