(Statistical Multiplexing) In class, we saw that packet switching can make more efficient use of resources by taking advantage of the fact that only a fraction of potential senders are active at any time. In this problem, you will be asked to demonstrate this fact mathematically. Suppose we have a single link with capacity L bits per second and a population of users that generate data at r bits per second when busy. The probability that a user is busy generating data is p. a. What is the maximum number of users that can be supported using circuit switching? Call this value MC. b. Now suppose we use packet switching to support a population of MP users. Derive a formula (in terms of p, MP, N, L, and r) for the probability that more than N users are busy. [Hint: Start by using the binomial distribution to derive a formula for the probability that exactly N users are busy.]c. Plug in some numbers. Let L = 1 Mbps, r = 64 Kbps and p = 0.1. Give the value for MC. What is the probability that more than MC users are busy for MP = 2MC? What about MP = 4MC? [Note: Feel free to use a tool such as Mathematica or Excel, or even write a small program to compute these numerical values.]Note: 1 Kbps is 1, 000 bps, not 1, 024 bps. Same rule applies to 1Mbps, 1Mbps= 106 bps. Also note that if something is specified as Megabyte (8 ∗ 106 bits), Gigabyte (8 ∗ 109 bits), etc.

What tool can discover and report computer errors and conflicts that occur when you first turn on a computer and before the operating system?

For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. after converting to the postfix expression, the program should evaluate the expression from the postfix and display the result. what should you submit? write all the code in a single file and upload the .c file. compliance with rules: ucf golden rules apply towards this assignment and submission. assignment rules mentioned in syllabus, are also applied in this submission. the ta and instructor can call any students for explaining any part of the code in order to better assess your authorship and for further clarification if needed. problem: we as humans write math expression in infix notation, e. g. 5 + 2 (the operators are written in-between the operands). in computer's language, however, it is preferred to have the operators on the right side of the operands, ie. 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: rubric: 1) if code does not compile in eustis server: 0. 2) checking the balance of the parenthesis: 2 points 3) incorrect postfix expression per test case: -2 points 4) correct postfix but incorrect evaluation per test case: -i points 5) handling single digit inputs: maximum 11 points 6) handling two-digit inputs: 100 percent (if pass all test cases)
