Question 6
Proxy Firewall operates at which layer of OSI Model
Question 7
A partial ordered relation is transitive, reflexive and
Question 8
Consider three CPU-intensive processes, which require 10, 20 and 30 time units and arrive at times 0, 2 and 6, respectively. How many context switches are needed if the operating system implements a shortest remaining time first scheduling algorithm? Do not count the context switches at time zero and at the end.
Question 9
Consider the join of a relation R with relation S. If R has m tuples and S has n tuples, then the maximum size of join is
Question 10
Four matrices M1, M2, M3 and M4 of dimensions p x q, q x r, r x s and s x t respectively can be multiplied in several ways with different number of total scalar multiplications. For example, when multiplied as ((M1 x M2) x (M3 x M4)), the total number of multiplications is pqr + rst + prt. When multiplied as (((M1 x M2) x (M3) x M4), the total number of scalar multiplications is pqr + prs + pst.
If p = 10, q = 100, r = 20, s = 5 and t = 80, then the number of scalar multiplications needed is
If p = 10, q = 100, r = 20, s = 5 and t = 80, then the number of scalar multiplications needed is
