A server accepts and processes requests from clients. The server keeps the results of the most recent requests in memory as a cache. A new request arrives on average every 25 ms. The processing of each request takes 15 ms. If the requested result is not in the memory cache, additional 75 ms are needed to access the disk. On average, 80% of all requests can be serviced without disk access. The creation of a new thread takes 10 ms. Required:
a. Should the server be implemented as a single-threaded or a multi-threaded process?
b. What percentage of disk accesses would have to be satisfied without disk access for the two approaches to break even?

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.
