Description: Address space management is a fundamental process in computer systems that handles the allocation and deallocation of memory addresses to running processes. This process allows each program to have its own address space, ensuring that it does not interfere with other programs. Address space management is based on the idea that each process needs a set of memory addresses it can use without worrying about the memory used by other processes. This is achieved through techniques such as paging and segmentation, which divide memory into manageable blocks. Paging, for example, allows physical memory to be divided into fixed-size pages, while segmentation allows memory to be divided into variable-size segments, depending on the needs of the process. Efficient address space management is crucial for system performance, as it affects memory access speed and resource utilization. Additionally, it is essential for security, as it isolates processes from each other, preventing a malicious process from accessing another’s memory. In summary, address space management is a key component in the architecture of modern computer systems, ensuring both efficiency and security in the simultaneous execution of multiple processes.
