Pronunciation: [a͡ɪ ˈə͡ʊ mˈap] (IPA) 
The spelling of the word "I O map" can be confusing, but it is pronounced as /aɪoʊ mæp/. The combination of the letters "I O" represents the diphthong /aɪoʊ/, which is a blend of the long "i" sound and the "o" sound. The word "map" is spelled as it is pronounced, with the short "a" sound and the consonant "p" at the end. To properly pronounce "I O map," stress is placed on the first syllable, "I O."
I/O map, also known as I/O memory map or Input/Output memory map, refers to a technique used in computer architecture and operating systems to allocate and access the Input/Output (I/O) devices of a computer system.
In simple terms, an I/O map can be understood as a logical mapping or assignment of memory addresses to the various I/O devices connected to a computer. Each I/O device, such as a keyboard, mouse, monitor, printer, or network interface card, is assigned a specific range of memory addresses.
The I/O map serves as a communication interface between the central processing unit (CPU) and the I/O devices. When an instruction or command is executed that requires interaction with an I/O device, the CPU communicates with the corresponding device by reading from or writing to the memory address associated with that device. This allows the CPU to send or receive data to or from the device, controlling its operation and facilitating data transfer.
The I/O map provides a standardized and organized approach to access and manage I/O devices in a computer system. It ensures that each device has a unique memory address range and allows for efficient control and coordination of the devices. The I/O map is typically implemented through hardware and supported by the operating system, which provides drivers and software interfaces for interacting with the I/O devices.
