### Question 13: Types of Memory Maps**Question:** Identify the two types of memory maps and draw examples of each.**Explanation:** Memory maps are essential tools in computing and memory management. They provide a visual representation of how memory is allocated and organized in a system. **Types of Memory Maps:**1. **Physical Memory Map:** - **Description:** Represents the entire memory space as directly addressed by the hardware. This map includes all memory components, such as RAM, ROM, and memory-mapped I/O devices. - **Example:** A diagram showing the distribution of RAM, ROM, and I/O devices within the available addresses.2. **Virtual Memory Map:** - **Description:** Used by operating systems to provide an abstraction of the physical memory. It allows programs to use memory addresses independently from the actual physical locations, enabling efficient memory use and multitasking. - **Example:** A chart illustrating the mapping between virtual addresses (used by applications) and physical addresses, including page tables and swap areas.**Diagrams:**- The diagrams typically depict a segmented view of memory blocks, showcasing boundaries and specific allocations for different types of memory. Each segment is labeled according to its function or data type.**Conclusion:** Understanding physical and virtual memory maps is crucial for grasping how operating systems manage memory and allocate resources efficiently.

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

The rationale behind the inclusion of cache memory in computer systems is not clear to me, given that transistors are utilised in the construction of both random access memory (RAM) and read-only memory (ROM).Temporary storage can be conceptualised as a transiently available form of RAM (random access memory). Can one envision a computing device that solely relies on a single type of memory?
