While opening a TCP connection, the initial sequence number is to be derived using a time-of-day (ToD) clock that keeps running even when the host is down. The low order 32 bits of the counter of the ToD clock is to be used for the initial sequence numbers. The clock counters increments once per millisecond. The maximum packet lifetime is given to be 64s. Which one of the choices given below is closest to the minimum permissible rate at which sequence numbers used for packets of a connection can increase?
Which one of the choices given below is closest to the minimum permissible rate at which sequence numbers used for packets of a connection can increase?
Option A. 0.015/s
Option B. 0.064/s
Option C. 0.135/s
Option D. 0.327/s
True Answer A
Explanation :
Solution:
The maximum packet lifetime is given to be 64 seconds in the question.
Thus, a sequence number increments after every 64 seconds.
So, minimum permissible rate = 1 / 64 = 0.015 per second

Which of the following functions can help us to find the version of python that we are currently working on?
Option A. sys.version
Option B. sys.version()
Option C. sys.version(0)
Option D. sys.version(1)
True Answer A
Explanation :
The function sys.version can help us to find the version of python that we are currently working on. For example, 3.5.2, 2.7.3 etc. this function also returns the current date, time, bits etc along with the version.
Which of the following functions can help us to find the version of python that we are currently working on?
What will be the output of the following Python code?
s=["pune", "mumbai", "delhi"] [(w.upper(), len(w)) for w in s]
Option A. Error
Option B. [‘PUNE’, 4, ‘MUMBAI’, 6, ‘DELHI’, 5]
Option C. [PUNE, 4, MUMBAI, 6, DELHI, 5]
Option D. [(‘PUNE’, 4), (‘MUMBAI’, 6), (‘DELHI’, 5)]
True Answer D
Explanation :
If we need to generate two results, we need to put it in the form of a tuple. The code shown above returns each word of list in uppercase, along with the length of the word. Hence the output of the code is: [(‘PUNE’, 4), (‘MUMBAI’, 6), (‘DELHI’, 5)].
What will be the output of the following Python code?
s=["pune", "mumbai", "delhi"] [(w.upper(), len(w)) for w in s]
