Assignments CN-2025-2026 IoT-B
1 TCP Calculator Server & TCP Client: Design and implement a TCP client–server application using IPv4 that behaves like a remote calculator. The TCP client sends three values to the server: (1) Operand 1, (2) Operand 2, and (3) an arithmetic operation. For example, when the client sends 23, 11, and the + operator, the TCP server performs the computation and returns the result 34 back to the client.

2 UDP Server Client for Debit/Credit Card Authenticity Checking : There is a hidden mathematical pattern in every credit or debit card number. Sup- pose you have a card number in the format ABCD-EFGH-IJKL-MNOP. To verify the authenticity of the card, we define three numbers: X, Y, and Z. - X = 2 × (A + C + E + G + I + K + M + O) - Y = Count of digits among A, C, E, G, I, K, M, and O that are greater than or equal to 5 - Z = B + D + F + H + J + L + N + P. - Z = B + D + F + H + J + L + N + P. If (X + Y + Z) mod 10 = 0, then the credit or debit card number is considered valid. Write two UNIX C program to verify the validity of a card number. One udp serever named UDPserver.c, which receives a 16-digit card number from the terminal. Another program named UDPclient.c, which starts computing X, Y, and Z and checks the card validity once the 16-digit number are received.

3 Configuration of Multiple VLANs with Inter-VLAN Routing: Design and configure a network consisting of multiple VLANs with multiple PCs using a Layer-2 switch and a router. Implement Inter-VLAN Routing so that PCs in different VLANs can communicate with each other. Pleas find the atatchemnt for more dteails
