give address according to size of memory like 128x8 FOR SINGLE CHIP it means 27=128, 7no off line and 16bit add bus &data bus 8bit,
add start 0000H to 007F

(Electronics & Computer Science / Computer Science) a technique whereby computer peripherals may be addressed as though they formed part of the main memory of the computer. (Khanu Piyar)
Virtual Mapping is one of Computer architecture concepts which a process thinks that it's only process on the machine ( at least on the memory). the benefit of that to ensure the security of Multitasking systems.
The purpose of a page frame in computer memory management is to provide a fixed-size block of physical memory that can be used to store a page of data from virtual memory. This helps in efficiently managing memory resources and allows for the mapping of virtual memory addresses to physical memory locations.
Direct mappingA given Main Memory block can be mapped to one and only one Cache Memory line.It is Simple, Inexpensive, fastIt lacks mapping flexibilityAssociative mappingA block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)It is slow, expensiveIt has mapping flexibility
Maps are one of your 5 a day, so is MILK :D AND CHICKAN
memory mapping
The differences among direct mapping and set-associative mapping :Direct mapping : Each line in main memory maps onto a single cache line.Set-associative : Each line in main memory maps onto a small (collection) set of cache line.Direct mapping : A memory block is mapped into a unique cache line, depending on the memory address of the respective block.Set-associative : A memory block is mapped into any of the line of a set. The set is determined by the memory address, but the line inside the set can be any one.dont knowyet

memory mapping
mapping is the procees of comparing the two
A mapping from logical address to physical address is essential for memory management in computer systems, as it allows the operating system to abstract the physical memory layout from applications, enabling efficient memory allocation and protection. This mapping is typically achieved through mechanisms such as paging and segmentation, which break down memory into manageable units. Protocols involved in this process include the Memory Management Unit (MMU) protocols, which translate logical addresses generated by programs into physical addresses in RAM, and the use of page tables to keep track of the mapping. Additionally, virtual memory protocols allow systems to use disk space as an extension of RAM, further enhancing memory efficiency.
