Host A sends a packet to host B over a link with a distance 1500 km (propagation speed 2.5x108 m/s). When the packet arrives, one other packet is halfway done being transmitted on this outbound link and three other packets are waiting to be transmitted. Suppose all packets are 1,500 bytes and the link rate is 5 Mbps. Each packet is processed before entering the link (and link buffer), and the packet processing delay is 0.2 ms. Please calculate the following delays in ms (millisecond).
Queueing delay = ... ms
Transmission delay = ... ms
Propagation delay = ... ms
The end-to-end delay = ... ms
Given that the packet arrival rate is 150 packet/s, calculate the traffic intensity for this link.
... % (fill in integer percentage value, e. g. fill in 35 for 35%)

We as humans write math expression in infix notation, e. g. 5 + 2 (the operators are written in-between the operands). in a computer’s language, however, it is preferred to have the operators on the right side of the operands, i. e. 5 2 +. for more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix. write a program that takes an “infix” expression as input, uses stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % (example infix expression: (7 - 3) / (2 + 2)postfix expression: 7 3 - 2 2 + /result: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
