Processing a read to a page not resident in a frame involves identifying the page, allocating or choosing a frame to load it into, and updating the page table to reflect the new mapping between the virtual and physical addresses.
When a read to a page of a virtual address space is requested but the page is not resident in a frame, the system needs to retrieve it from secondary storage. Here are the steps involved in processing this request:
1. A page fault is generated when the system attempts to access a page that is not currently resident in a frame.
2. The operating system identifies the page that needs to be brought into memory and creates a new page table entry for it.
3. The system checks if there is a free frame available in the memory. If there is, the page is loaded into the frame, and the page table is updated to reflect the new mapping between the virtual page and the physical frame.
4. If there is no free frame available, the system needs to choose a victim frame to replace it with the new page. The victim frame is selected based on the page replacement algorithm used by the system.
5. The page is then loaded from the secondary storage into the selected frame, and the page table is updated to reflect the new mapping.
6. Finally, the system returns control to the user program, and the read operation can proceed with the requested page now resident in memory.

module can be examined independently.
-Refinement
-Modularity
-Abstraction
-Control hierarchy
is a process that elaborates on each design component until it reaches the coding details.
-Software procedure
-Structural partitioning
-Data Structure
allows designers to split a program structure horizontally and vertically.
-Software architecture
-Structural partitioning
-Modularity
-Data Structure
represents logical relationships between individual data elements.
Answer:
1. Modularity.
2. Refinement.
3. Structural partitioning.
4. Data Structure.
Explanation:
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;
1. Planning.
2. Analysis.
3. Design.
4. Development (coding).
5. Deployment.
6. Maintenance.
One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.
Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard. Some of the models or techniques used in the design of a software are;
Modularity: refers to the concept that software architecture has the ability to divide into modules and that eachmodule can be examined independently. Refinement: is a process that elaborates on each design component until it reaches the coding details.Structural partitioning: allows designers to split a program structure horizontally and vertically.Data Structure: represents logical relationships between individual data elements.Page No
