Operating System
Consider a paging system which stores its two-level page table in memory and its 16 most recently referenced entries in a TLB. If, a memory access takes 80 nsec, a TLB lookup takes 20 nsec and a page swap time takes 5000 nsec, how long does a data item take to access if the TLB hit rate is 95% and the page fault rate is 10% ?

TIFR CSE 2019 | Part A | Question: 14
A drawer contains $9$ pens, of which $3$ are red, $3$ are blue, and $3$ are green. The nine pens are drawn from the drawer one at at time (without replacement) such that each pen is drawn with equal probability from the remaining pens in the drawer. What is ... that two red pens are drawn in succession ? $7/12$ $1/6$ $1/12$ $1/81$ $\text{None of the above}$
