memory management
The purpose of a page frame in computer memory management is to provide a fixed-size block of physical memory that can be used to store a page of data from virtual memory. This helps in efficiently managing memory resources and allows for the mapping of virtual memory addresses to physical memory locations.
The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.
The purpose of the head string pool in a programming language is to store and manage commonly used string literals in memory. This helps reduce memory usage by reusing the same string objects instead of creating new ones every time they are used. This can improve memory management by reducing the amount of memory allocated for storing duplicate string literals, leading to more efficient use of memory resources.
function of memory management
MS-DOS does not have built-in memory management.
static memory management i.e we are fixed the memory location with there size & that fixed size jobs will appear
Swapping was an older form of memory management. It was moving from/to secondary storage a whole program at a time, in a scheme known as roll-in/roll-out. Now swapping is a fairly close synonym of paging.

Memory management is the method by which a computer stores and retrieves memory. It works by the computer organizing data by types and storing it accordingly.
Role of the Memory management unit in Operating system Every program for its execution requires some space in computer memory which is provided by memory management unit using virtual memory that provides the external storage addressing location for the programs that does not have too much space in main memory for their execution and saved them in secondary memory but when required loaded them again in main memory. This deallocation and reallocation of programs in main memory deals with concurrency. At last, we say that loading capabilities of programs with the memory addressing is there in it.
