- The most important tables in the library information system are the following. Books (bid, author, title, publisher, year); Members (mid, name, surname, address, telephone); Rental (rid, mid, bid, eid, date); Employee (eid, name, surname, address, telephone) All tables are sorted according to the key. The following information is given. 1 page on the disk = 8KB |Books| = 1.000.000 records, 320 bytes, 25 records/page, 40000 pages |Members| = 10.000 records, 200 bytes, 40 records/page, 250 pages |Rental| = 300.000 records, 40 bytes, 200 records/page, 1500 pages |Employee| = 100 records, 200 bytes, 40 records/page, 3 pages We can have 25.000 pages in the buffer. QUESTION 2.1 B+ index is used on the attribute Books.publisher. The size of the record identifier is 8B, the size of the page identifier is 6B.

- Exactly what is meant by "dynamic memory allocation," and how does it work in practice? What benefits does the user get from using this function? If there is more than one kind of dynamic memory allocation or allocator, please describe each one.A page table may contain named entries (memory mapped files, such as code of an executable program) and anonymous mappings (page not backed by a file, such as the heap and stack of a program). Explain why (and how) a page fault handler has to handle these two cases differently when it needs to (1) evict a page from physical memory and (2) load a page into physical memory.Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int…

- Table 1 shows the content inside computer memory addresses. The code listed in Table 2 is designed to sum the numbers stored in 10 locations beginning with x3100, leaving the result in R1. The initial value of R1 is 0, R2 is x3100 and R4 is 10. Your task is to trace the content of R1, R2, and R4. Table 3 is given as a guide on how to write the contents of the registers.

Also assume that each transaction takes, on average, a fixed amount of time to process. The following table shows pairs of transaction latency and processing rate. Average Transaction Latency Maximum transaction processing rate 1 ms 2 ms 1 ms 2 ms 5000/sec 5000/sec 10,000/sec 10,000/sec For each of the pairs in the table, answer the following questions:> On average, how many requests are being processed at any given instant?> If move to an 8-core system, ideally, what will happen to the system throughput (i.e., how many queries/second will the computer process)?> Discuss why we rarely obtain this kind of speedup by simply increasing the number of cores.
