If you want to learn some information about the memory management, this post is what you need.
Besides, you could know why you better use it in your operating system.
Whats more, here is some information about the memory management techniques.
Now, keep on your reading.
What Is Memory Management
What is memory management?
It is the process of controlling and coordinating computer memory.
Parts called blocks are allocated to various running programs to optimize overall system performance.
Memory management resides in hardware, operating system, and programs and applications.
How Does It Work?
Main memory refers tophysical memory, which is the internal memory of the computer.
The main memory is also calledRAM.
The computer can only change the data in the main memory.
This mechanism is called dynamic loading, which can improve performance.
The details are as follows:

Memory Management Techniques
Here are some of the most critical memory management techniques.
Segments require hardware support in the form of segment tables.
Single Contiguous Allocation
Contiguous memory allocation in OS is the simplest memory management technique.
For example, the MS-DOS operating system allocates memory in this way.
Do you know how to get rid of invalid MS-DOS function on your Windows computer?
Now, in this post, we will show you some effective solutions.
Eachpartitionstores all information for a specific task or job.
Its working methods include allocating a partition when the job starts and canceling the allocation when the job ends.
Paged Memory Management
This method divides the computers main memory into fixed-size units, called page frames.
The hardware memory management unit maps pages into frames that should be allocated according to pages.
Memory Allocation
Memory allocation is a process of allocating memory or space for computer programs.
It has three types.
First Fit:
The first hole large enough is assigned to the program.
Best Fit:
The smallest enough hole is assigned to the program.
Worst Fit:
Largest enough holes to be assigned to the program.
Therefore, redundant processes will remain on the disk and make it run dynamically.
The Windows memory management error occurs frequently on the computers blue screen.
