explain in detail the steps in the processing of a read to a page of a virtual address space that is not resident in a frame but is stored on secondary storage

Answers

Answer 1

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.

What is the difference between the casual and consultative conversation? Why is it important for a person to know the difference between the two?​

Answers

Answer:

The answer is below

Explanation:

Casual conversation is a form of conversation that occurs between friends and families. There are no specific rules or manner in which the participants speak to each other. It is otherwise known as Informal Conversation.

Consultative conversation on the other hand is a form of conversation that occurs between people who have a close relationship but not actual friends or families.

For example, people involved in this type of conversation are the likes of Doctors and Patients, Counsellors and Students, etc. It is often considered a Semi-formal conversation.

The reason a person needs to know the difference between the two styles of conversation is for individuals to know how to present and conduct themselves appropriately during the conversation.

Answers

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.
