COMPUTER SCIENCE Recall, in our discussion of the Church–Turing thesis, that we introduced the language $D=\{\langle p\rangle | p$ is a polynomial in several variables having an integral root}. We stated, but didn’t prove, that D is undecidable. In this problem, you are to prove a different property of D-namely, that D is NP-hard. A problem is NP-hard if all problems in NP are polynomial time reducible to it, even though it may not be in NP itself. So you must show that all problems in NP are polynomial time reducible to D. Verified answer COMPUTER SCIENCE The RC 4000 system, among others, has defined a tree of processes (called a process tree) such that all the descendants of a process can be given resources (objects) and access rights by their ancestors only Thus, a descendant can never have the ability to do anything that its ancestors cannot do. The root of the tree is the operating system, which has the ability to do anything. Assume that the set of access rights is represented by an access matrix, A. A(x, y) defines the access rights of process x to object y. If x is a descendant of z, what is the relationship between A(x, y) and Z(z, y) for an arbitrary object y? Verified answer

Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination.
Which one is not a type of topology?Explanation: The types of topology are bus topology, ring topology, star topology, mesh topology and hybrid topology. Connect is not one of them.
