Socket programming in c language in windows Implement one server and three clients using multithreaded exchanging messages between them and then doing checksum error detection or parity

In computing, time scales usually store the current time as the number of seconds that have elapsed since the beginning of some “epoch”, which is an arbitrary date that determines the starting time. For example, the Network Time Protocol (NTP) uses an epoch of midnight on January 1st (GMT) 1900. The elapsed seconds since the epoch are stored in a 32-bit unsigned integer. In many embedded systems, it is more practical to just consider the current year. In this case, the format is often modified such that 0 corresponds to midnight on January 1stof the current year. If a clock that was initialized to 0 at midnight of 1 January 2020 currently has a count of 3665044 seconds, what day and time does it represent? (For example, your answer should be in the form June 6, 8:47:12 am) Show your work

In C/C++ network programming; create a simple web proxy that handles the connection between a client and server. I currently have been working on a client and server echoing each other from the geeks for geeks example but can't find much information in CODING up a web based proxy. I do understand the type of proxy to create but do not understand how to code one up in terms of client-proxy-server connection through https. The answer that I am looking for is how to create the web proxy in C. You can use the geeks for geeks example (client/server) or use one of your own.

Hello. I need help developing a C or C++ program that simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address,and frame destination address. The frames arrive at the switch in the order of which they appearin the input file. Destination address "X" indicates a broadcast frame.  Thank you!   ********************PLEASE YOUR CODE MUST BE COMPLETE, COMPILE AND EXECUTE****************   The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, here is an example:  "in.txt" contains 5 incoming frames:F1 P2 B--AF2 P6 D--CF3 P5 E--BF4 P7 F--DF5 P6 D--X"out.txt" should list the departing frames on each port:P1: F1 F2 F5P2: F2 F3 F5P3: F1 F2 F5P4: F1 F2 F5P5: F1…
