Consider a demand-paging system with a paging disk that has an average access and transfer time of 50 ms. addresses are translated through a page table in main memory, with an access time of 2 us per memory access. thus, each memory reference through the page table takes two accesses. to improve this time, we have added an associative memory (tlb) that reduces access time to one memory reference, if the page-table entry is in the associative memory (tlb). ssume that 90% of the accesses are in the associative memory (tlb), and that, of the remaining, 20%) or 2% of the total) cause page faults, what is the effective memory access time?

This program reads a file called 'test.txt'. you are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist. write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist. example: contents of 'test.txt': test file another line in the test file output: ['another', 'file', 'in', 'line', 'test', 'the']
