To study the operation of Ethernet and key concepts related to TCP/IP protocols by analyzing an Ethernet frame with a TCP packet. A specific network analyzer (many free- download versions available online) is to be used to capture network data frames. Conduct an online search for "network protocol analyzer". A large number of candidates will show up. Test and then select the one which works best for you - the minimum requirement is the ability to catch Ethernet data frames with OSI model layers details presented. 1. Complete the following Table 1:
Table 1: Protocol analyzer information
Name of the analyzer

2. Run the protocol analyzer and capture network traffic. Among the data frames captured, select one Ethernet frame that has an embedded TCP frame. This Ethernet data frame will be the focus of the subsequent steps.
3. Insert in the box below (you may enlarge it as needed) a screen shot of the protocol analyzer with at least one captured Ethernet frame expanded to show the IP packet and enclosed TCP header, i. e. the headers at Data link, Network, and Transport layers should be shown explicitly.
4. Regarding the Ethernet frame, complete the following Table 2:

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';
