Network topologies (Star, Mesh, Ring, Bus), Transmission media (guided vs unguided), OSI 7-Layer Reference Model (functions, headers, and protocols of each layer), TCP/IP Protocol Suite, Data Link Layer protocols (Framing, Flow Control — Stop & Wait, Sliding Window, Error Detection — CRC, Checksum), Network Layer (IPv4 addressing, Subnetting, Classful vs Classless addressing, Routing algorithms), and Application Layer protocols (HTTP, HTTPS, FTP, SMTP, DNS).
In DBMS SQL questions, always write table aliases clearly and verify whether the prompt requires an INNER JOIN or an OUTER JOIN (e.g. showing customers who haven't placed orders requires a LEFT JOIN).
Important Exam Focus: OSI 7-Layer architecture with detailed function and protocol list for every layer; IPv4 addressing classes (A, B, C, D, E) and subnet mask calculations; Sliding Window protocol mechanism; TCP vs UDP comparison.
