Time Delay in Circuit Switching
A and B are 4 hops apart on a Circuit Switched Network where each hop is 100 mile long. Per hop processing delay is 5µs. Packets are 1500 Bytes long. All links have a Transmission speed of 56Kbps. speed of light in wire is 125,000 miles/s. If B sends a 10 packet message to A, how long will it take A to receive message up to the last bit?

A simple graph is one with no self-loops or multiple edges. Among the simple graphs with $n$ vertices and at most $20n − 3$ edges: There is always a graph with all vertices connected to at least $42$ other vertices. For all such graphs the number of vertices ... some constant $c < 1$. There are no graphs with each vertex connected to at most $38$ other vertices. None of the above

Consider the grammar given below : $S \rightarrow AB \mid DA$ $B \rightarrow BCD \mid ABD \mid CC \mid b$ $A \rightarrow a \mid BC$ $C \rightarrow aBD \mid a$ $C \rightarrow aBCAD \mid DaB$ $A \rightarrow aBCAD \mid Da$ ... following non terminal is useless in the grammar (as non terminal strings can be derived from it): $D$ $C$ $B$ $A$
