The exam assesses computer science concepts, focusing on data representation, system architecture, and functional programming. Topics include binary-to-hexadecimal conversion, Boolean algebra simplification, and truth table construction. Networking sections explore serial versus parallel data transmission, asynchronous transmission components, and DNS functionality. Relational database tasks cover SQL queries, normalization, and entity-relationship diagrams. Floating-point representation questions analyze normalization, conversion errors, and relative error calculations. Functional programming emphasizes higher-order functions, recursion, and mapping. Hardware-related tasks compare client-server and peer-to-peer networks, SSD operation, and thin-client versus thick-client requirements. Emphasis is placed on problem-solving, practical application, and theoretical analysis.
