Address Mapping in computer architecture plays a key role in organizing the communication between the different hardware components, rendering them more efficient and reliable. Also known as address translation or address binding, address mapping is a process in which an input address is linked or mapped to an output address. During this process, the computer system can either transform the address into an alternative format or simply convert an address from one system to another.<\/p>\n

Address mapping plays a key role in dealing with large physical address spaces. For instance, a large network, or the internet, consists of many different computers linked together. Without address mapping, their respective systems would not be able to connect with each other. Further, it also supports efficient communication between different hardware components, and provides data security by preventing unauthorized access. <\/p>\n

Every time an operating system requires data, it accesses memory using a virtual address, which is later translated into physical address by the computer’s hardware. This is done using a memory management unit (MMU), which stores the mapping of each address to its corresponding physical address. In modern systems, address mapping is an integral part of the memory management process. <\/p>\n

Memory segmentation is another important concept associated with address mapping. During this process, a machine’s memory is divided into distinct segments, each containing different types of data, such as program code and data. Each segment is assigned an address and each address is also associated with a particular segment. This allows the operating system to keep track of all the different components and restrict access to certain programs.<\/p>\n
