Does memory management in an operating system focuses on compressing files to save space and speeding up file transfer?

No, memory management in an operating system primarily focuses on managing the allocation and deallocation of memory for processes and ensuring that each process has access to the necessary memory resources. This includes tasks such as allocating memory for processes, freeing up memory when it is no longer needed, and preventing memory leaks. Compressing files to save space and speeding up file transfer are typically handled by file system management and disk management, rather than memory management.
