How can I solve this problem? Detailed steps would be appreciated as I really want to learn how to do it **Understanding Virtual Memory Systems**The following table shows the core map of a virtual memory system at time \( t \), which has a page size of 1000 bytes. In this table, the column "Counter" indicates the number of references on the corresponding page till time \( t \) (a small value indicates the least recently accessed page).| **Process ID** | **Page #** | **Frame #** | **Counter** ||----------------|------------|-------------|-------------|| 1 | 1 | 0 | 1 || 1 | 2 | 1 | 4 || 2 | 2 | 2 | 3 || 3 | 1 | 3 | 2 || 1 | 3 | 4 | 5 || 2 | 1 | 5 | 0 || 2 | 0 | 6 | 6 || 3 | 2 | 7 | 7 |Let's assume the given system has a memory of 8000 bytes. Right now (\( \text{@time t} \)), **process 1** issues a reference to its logical address 4500; there will be a page fault. If the system deploys the **LRU (Least Recently Used) algorithm** for page replacement with a **local replacement policy**, what is the corresponding physical address being referenced?**Question:** What is the corresponding physical address being referenced?- a. 5500- b. 500- c. 2500- d. 1500- e. 4500**Explanation:**In an educational context, this example helps illustrate concepts such as virtual memory, page replacement algorithms (specifically the LRU algorithm), and local replacement policy. The key learning points are:1. Understanding virtual memory and its organization into pages and frames.2. Recognizing how the LRU algorithm functions by replacing the least recently used page.3. Applying the local replacement policy to understand how the system decides on which page to replace when a page fault occurs.

EXPLANATION Below is the answer for the given question. Hope you understand it well. If you have any…

The following table shows the core map of a virtual memory system at time t, which has a page size of 1000 bytes. In this table, column "Counter" indicates the number of references on the corresponding page till time t [small value indicates the least recently accessed page]. Process ID Page # Frame # Counter 1 1 lo 1 1 2 4 2 3 3 1 3 2 3 4 lo 2 6 6 3 7 17 Let's assume the given system has memory of 8000 bytes. Right now (@time t), process 1 issues a reference to its logical address 4500, there will be a page fault. If the system deploys LRU algorithm for page replacement with local replacement policy, what is the corresponding physical address being referenced? O a. 5500 O b. 500 O c. 2500 O d. 1500 O e. 4500

Critique the following writing assignment, discussing improvement strategies. Manned, unmanned space travel has been a big controversy for many years; it’s too risky or space bots gets just as much done as humans. I agree 100% that robots are far better off into space than humans; manned space travel is too dangerous. Almost all the money for such a mission would be spent simply to keep the people alive. (John Tierney) Space bots are more reliable, don’t get tired, and do what it’s programed to do, but more proficient. Things humans need for survival includes: air, food, water, things we must take with us for space travel, which adds to the cost for each individual we fly out into space. While space bots don’t need any of these sources for survive, which makes space travel less expensive and more productive. Also the bots can retrieve more data because there aren’t any stopping periods for breaks or any other reasons for that matter. It cost about 1.3…
