Pronunciation: [ˈɛmmˈap] (IPA) 
The spelling of the word "MMAP" may seem strange, but it can be broken down phonetically. The first two letters, "MM," are pronounced as a double M sound [m̩m]. The next letter, "A," is pronounced as the short vowel sound "ah" [ʌ]. Lastly, the letter "P" is pronounced as the voiceless bilabial stop sound [p]. So if you put it all together, "MMAP" is pronounced [m̩mʌp]. With this knowledge, you'll be able to sound out the word correctly.
MMAP stands for Memory-Mapped Anonymous Pipes. It is a type of inter-process communication mechanism implemented in computer systems to facilitate data transfer and communication between processes or threads within the same system. MMAP is commonly used in Unix-based operating systems, such as Linux, to establish a form of communication pipe between two processes.
In this context, "memory-mapped" refers to the technique of mapping a region of virtual memory into the address space of a process or thread. The memory region is then shared between multiple processes, allowing them to read and write data to the same memory area. Anonymous pipes, on the other hand, are a type of communication channel that enables data exchange between two processes.
MMAP operates by creating a shared memory segment that both the sending and receiving processes can access simultaneously. The sender writes data into the memory region, which is then made visible to the receiver process for reading. This technique eliminates the need for explicit data copying between processes, resulting in improved efficiency and performance.
One advantage of using MMAP is its ability to efficiently transfer large amounts of data between processes without incurring the overhead associated with traditional pipe communication methods. Additionally, MMAP allows for more efficient memory utilization and reduces the need for context switching when transferring data between processes.
Overall, MMAP is a memory-mapping technique used to establish shared memory segments between processes, facilitating efficient and fast inter-process communication on Unix-based systems.
