Consider the following statements: 1. Let T be the DFS tree resulting from DFS traversal on a connected directed graph the root of the tree is an articulation point, iff it has at least two children. 2. When BFS is carried out on a directed graph G, the edges of G will ... as tree edge, back edge, or cross edge and not forward edge as in the case of DFS. Find TRUE or FALSE for both the statements

Consider a single-level cache with an access time of 1.8ns, a line size of 16 bytes, and a hit ratio of 0.85. Main memory uses a block transfer capability that has a first word (4 bytes) access time of 40 ns and an access time of 5 ns for each word thereafter. ... = 40ns(first 4 bytes) + 75 (remaining 60 bytes) How it get 75ns accesstime ? After 4 words each words is accessed at 5ns Access time.?

An undirected graph $G(V,E)$ contains $n \: (n>2)$ nodes named $v_1,v_2, \dots, v_n$. Two nodes $v_i, v_j$ are connected if and only if $ 0 < \mid i-j\mid \leq 2$. Each edge $(v_i,v_j)$ is assigned a weight $i+j$. A sample graph with $n=4$ is shown below. What will be the cost of the minimum spanning tree (MST) of such a graph with $n$ nodes? $\frac{1}{12} (11n^2 - 5 n)$ $n^2-n+1$ $6n-11$ $2n+1$

Suppose that it takes $1$ unit of time to transmit a packet (of fixed size) on a communication link. The link layer uses a window flow control protocol with a window size of $N$ packets. Each packet causes an ack or a nak to be generated by the receiver, and ack/nak transmission times are negligible. Further, ... is $1- \dfrac{ N}{i}$ $\dfrac{i}{(N + i)}$ $1$ $1 - e^{\left(\frac{i}{N}\right)}$

A push down automation (pda) is given in the following extended notation of finite state diagram: The nodes denote the states while the edges denote the moves of the pda. The edge labels are of the form $d$, $s/s'$ where $d$ is the input symbol read and $s, s'$ are the stack ... states in the above notation that accept the language $\left\{0^{n}1^{m} \mid n \leq m \leq 2n\right\}$ by empty stack
