Memory is constructive in nature.

What one remembers is sometimes shaped by what one expects.

Which of the following is NOT a good reason to doubt a personal experience?

Someone’s inability to disprove a claim is evidence that it’s true.

When one sees a distant light moving, even though it’s stationary, one is experiencing:

Without the laws of thought, communication would be impossible.

How many deductive arguments are sound?

What is an access path?

Given two files A and B and each file include 3 pages (each page contains 4 entries only) as shown as the following: A: , ,] B: , , ] Assume you have 3 buffer pages in the main memory.            Show the 2-way merge sort (sort each page separately in the first pass, and then merge in the subsequent passes) procedure for the given example.     2. Compute the I/O cost for this procedure (rounding the value up)

Assuming that you have a three-frame buffer pool. Please show the buffer content given the workload listed in the table below using LRU and MRU strategies. We start from T1 and moves forward by one on each page reference. For your solution, underline the letter in the frame in the buffer pool each time that memory access caused a “miss” in the buffer pool (i.e., a page is read that is not currently in the buffer pool), when the page is put in the buffer pool. When the buffer pool has unused slots (such as at the beginning, when all slots are empty), it will put newly read data in the first unused slot.  The pages to be read from the disk are labeled A through D.  For each access, the page is pinned, and then immediately unpinned. Assume one page on disk fits perfectly with one frame on the buffer pool.   Time Page Read T1 A T2 B T3 C T4 D T5 B T6 C T7 D T8 C T9 D T10 A    1. In your answer, please create two buffer pools, one for LRU strategy and one for MRU strategy.
