Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

In this and the following question, consider those TMs that satisfy all of the following properties: Q={90,91,9a9r}: there are exactly two states besides the accept state and the reject state. • Σ={1}: the input alphabet has just one symbol. • [={1,_}: the tape alphabet has two symbols, where is the blank symbol. • The head is moved in every step, that is, 8 uses only L and R, but not N. • If the machine is started on the completely empty tape, it will halt after a finite number of steps, that is, it will reach qa or qr. If such a TM is started on the completely empty tape, it will leave a certain number of 1 symbols on the tape after it halts. What is the maximum number of 1 symbols on the tape, among all of these TMs? Answer: Check Consider again the TMs of the preceding question. If such a TM is started on the completely empty tape, it will make a certain number of transition steps. What is the maximum number of steps, among all those TMs? Answer: Check

Suppose we have a video of two white points moving toward each other at a uniform rate against a black background. We encode it via MPEG. In one I frame the two points are 100 pixels apart; in the next I frame they have merged. The final point of merger happens to lie at the center of a 16 x 16 macroblock. (a) Describe how you might optimally encode the Y component of the intervening B (or P) frames. (b) Now suppose the points are in color and that the color changes slowly as the points move. Describe what the encoding of the U and V values might look like.
Consider a system that implements demand paging without a TLB. The single-level page table is held in memory, and we assume that there are no free frames. Each memory access requires 100 nanoseconds. It takes 6 additional milliseconds to handle a page fault if the victim page is not "dirty" or 12 additional milliseconds if the victim page is "dirty". Experiments show that the probability of page faulting is 0.00003 (i.e., 0.03% chance) and that the average memory access time is 400ns. What is the percent chance that a page is dirty at the time it is evicted? Hint: Call the "being dirty" probability d and write a simple equation that gives the average data access time as a function of d. Solve for d (the result should be a number between 0 and 1, which you then convert to a percentage).

Suppose a file of 10,000 bytes is to be sent over a line at 2400 bps. A. Calculate the overhead in bits and time in using asynchronous communication. Assume one start bit and a stop element of length one bit, and 8 bits to send the byte itself for each character. The 8-bit character consists of all data bits, with no parity bit. B. Calculate the overhead in bits and time using synchronous communication. Assume that the data are sent in frames. Each frame consists of 1000 characters = 8000 bits and an overhead of 48 control bits per frame. C. What would the answers to parts (a) and (b) be for a file of 100,000 characters?
