Advantage: Simplifies decoding: Fixed length instructions make decoding and fetching instructions easier, as the processor knows the exact length of each instruction. Faster processing: Fixed length instructions allow the processor to fetch and decode instructions quickly, leading to faster overall processing speeds. Disadvantage: Wastage of memory: Fixed length instructions may lead to wasted memory space if shorter instructions do not fully utilize the allotted space. Limited flexibility: Fixed length instructions limit the complexity and variety of instructions that can be encoded, restricting the range of operations a processor can perform.

Fixed partition memory management offers simplicity and ease of implementation, as memory is divided into fixed-size segments, making allocation straightforward. However, its main disadvantage is inefficient memory utilization; if a process requires less memory than a partition size, the remaining space is wasted (internal fragmentation). Additionally, the fixed size can lead to difficulties in accommodating processes of varying sizes, potentially causing underutilization of available memory resources.
in the fixed partition the partition is once allocated is fixed. in fixed partition more memory wastage because of internal & external fragmentation.... in variable partition when a process comes then according to need of process the size of memory is allocated to the process
ARM processor instructions are encoded to optimize performance and memory efficiency. By using a fixed-width or variable-width instruction format, ARM can reduce the size of the binary code, allowing for more efficient use of cache and memory. This encoding also facilitates easier decoding and execution of instructions by the processor, which can lead to faster execution times. Additionally, it allows for a rich set of instructions while maintaining a compact representation, contributing to the overall effectiveness of ARM architecture in various applications.

A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time. The main memory (which is the volatile memory where active programs and data are held during use), is divided into partitions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run. So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size. And a process is loaded into a partition big enough to hold it.
Fixed partitions have fixed size and usually cannot be easily expended or shrunk. Dynamic partitions can change size by themselves when they need it. There are some advantages of using fixed partitions because you control its size. It might happen that you can run out of free space when you are using dynamic partitions.
Partitioned allocation is a fixed memory allocation technique which memory spaces are divided into smaller fixed partition, while Relocatable partitioning use variable and repartitioning technique
