Final answer:
Fixed Partitioning memory management was plagued by internal fragmentation, limiting multitasking due to a fixed number of processes, and was inefficient in adapting to varying process sizes.
Step-by-step explanation:
A problem with the largely obsolete Fixed Partitioning memory management technique is that of inefficient use of memory, a fixed number of processes, and internal fragmentation. This specific method of memory allocation divided memory into fixed-size partitions where each partition might contain exactly one process. When a process did not utilize the entire partition, the leftover space, termed as internal fragmentation, was wasted as it could not be used by other processes or the operating system. In contrast to more modern techniques like dynamic partitioning or paging, fixed partitioning was not able to adapt efficiently to different process sizes, which often led to a poor utilization of memory.
Moreover, fixed partitioning enforced a fixed number of processes, limiting multitasking capabilities. Not to mention, ensuing problems such as external fragmentation and the complexity of accommodating larger or smaller processes than the fixed sizes were pronounced. Newer memory management techniques provide solutions to these issues by allowing dynamic resizing and better overall memory utilization.
