Assume there is a file which consists of 20 blocks. Consider that the file-control block is already stored in the memory. Calculate the number of disk I/O operations are required for contiguous and linked allocation strategies, if, for one block, the following conditions hold. Also assume that the block information to be added is stored in memory.

a. The block is added at the beginning.

b. The block is added in the middle.

c. The block is added at the end.

Note: Make suitable diagrams to illustrate the complete process rather than writing the direct results or answers.

Answer : For evaluating the 5^532 mod 36 by using the method of repeated squaring the approach to do this is repeatedly observing the results of 5^532 mod 36 and as the result becomes continuous.

So, 5^532 mod 36 = (5^5 + 5^3 +5^2)^36 mod 0 = (3125 + 125 + 25) ^36 mod 0 = (3125^4 + 123^2 + 25^1) mod 36 = (71452)^x where x is almost reaching infinity. So as per the calculations and algorithm the answer would not be definite as per the laws of repeated squaring method.

Consider a file currently consisting of 100 blocks. Assume that the File Control Block (or, the index block, in case of indexed allocation) is already in the RAM. Calculate how many disk I/O operations (“read block” or “write block”) are required for contiguous, linked, and indexed (single-level) allocation strategies, if the following conditions hold (In the contiguous allocation case, assume that there is no room to grow in the beginning, but there is a room to grow in the end....

Consider a file currently consisting of 200 blocks. Assume that the file control block (and the index block, in the case of indexed allocation) is already in memory. Calculate how many disk I/O operations are required for contiguous, linked, and indexed (single-level) allocation strategies, if the following conditions hold. In the contiguous allocation case, assume that there is no room to grow in the beginning, but there is room to grow in the end. Assume that the block information to...

Consider the following four blocks, all of which are attached to identical springs: block A: mass = 200·g, spring stretched 10·cm block B: mass = 800·g, spring stretched 20·cm block C: mass = 400·g, spring stretched 20·cm block D: mass = 400·g, spring stretched 20·cm. (a) All the blocks are placed on a level surface that has no significant friction. For each of the following ranking tasks use the symbols > and = to indicate your ranking (ties are possible),...

For this question (Determine the velocity of the 60 kg block A if the two blocks are released from rest and the 40 kg block B moves 0.6 m up the in cline. The coefficient of kinetic friction between both blocks and the inclined planes is = 0.05.), how is T(2) = 110 V(a)^2 instead of T(2) = -50V(a)^2

Suppose that two blocks are positioned on an Atwood machine so that the block on the right of mass m1 hangs at a lower elevation than the block on the left of mass m2. Both blocks are at rest. Based on this observation, what can you conclude? A) m1>m2 B) m1<m2 C) m1=m2 D) You cannot conclude anything with the given information.

Given the mass of two blocks that collide, and the velocities of each block before and after the collision, be able to determine whether the collision was elastic, partially or completely inelastic, or not possible since an unnamed external force would be necessary to change the momentum, and/or kinetic energy of the system. Please explain in simplest terms and give an example using units given.
