EXTENDED MEMORY Meaning and
Definition
-
Extended memory refers to the additional storage capacity beyond the boundaries of conventional or base memory available in a computer system. It typically refers to the memory space that exists beyond the first 1MB of memory in a computer's physical address space.
In the early days of computing, there was a limitation on the amount of memory that could be directly accessed by the processor. This limitation was due to the addressing scheme used by the processor, which could only address a maximum of 1MB of memory. However, as the demand for more memory in computers increased, computer manufacturers introduced techniques to overcome this limitation, leading to the concept of extended memory.
Extended memory is primarily achieved through the use of memory management techniques, such as the Extended Memory Specification (XMS) and Expanded Memory Specification (EMS). These techniques allow the operating system and applications to access and utilize memory beyond the 1MB limit.
Extended memory provides a means to increase the overall memory capacity of a computer system, allowing for the execution of more complex and memory-intensive tasks. It enables the computer to store and retrieve larger amounts of data, leading to improved performance and multitasking capabilities.
In modern computer systems, extended memory is typically represented by random access memory (RAM) modules, which can be added or upgraded to increase the available memory capacity beyond the base memory. This expanded memory serves as a crucial resource for running resource-demanding applications, enabling smoother operations and overall system performance.

Etymology of EXTENDED MEMORY
The term "extended memory" originated in the field of computer science and technology. It refers to an additional portion of memory that is beyond the capacity of the central processing unit (CPU) to directly access.
The etymology of "extended memory" can be broken down as follows:
1. Extended: This term indicates the concept of expanding or increasing something beyond its original or usual limit. In the context of computer memory, "extended" refers to the expansion of the available memory beyond the primary or basic memory.
2. Memory: In computing, "memory" refers to the physical or virtual storage space used to store data and instructions that the CPU can access.
Therefore, the term "extended memory" emerged from the need to describe the additional memory capacity beyond the limitations of the CPU, allowing it to store and retrieve data and instructions efficiently.
