CEC 441 TCP & IP Socket Programming Exam 2026

About this paper

CEC 441: First Semester Examinations for CEC441, TCP/IP Socket Programming, College of Technology, University of Buea, instructor Mr. Tatsachou Dieunedort, time allowed 2 hours. Part One asks students to explain socket states and the socket lifecycle, the difference between TCP and UDP sockets, the roles of buffer(), connect(), bind(), listen() and accept() in TCP socket programming, how to ensure data integrity over a socket connection, what a socket address is and why it is needed, and a scenario for using multicast and raw sockets. Part Two is a practical TCP client-server programming task: the client sends an integer to the server, the server computes and returns the multiplication table of that number one value at a time (e.g. for input 3: 3x1=3, 3x2=6, ..., 3x10=30), requiring students to write the client code, the server code, and explain the main difference between a server socket and a client socket.
