Basic computer organization, Instruction codes, Computer registers, Instruction cycle (Fetch, Decode, Execute), Addressing modes (Immediate, Direct, Indirect, Register, Relative, Indexed), Central Processing Unit (CPU) architecture, Arithmetic Logic Unit (ALU) design, Memory Hierarchy, Cache Memory Mapping (Direct Mapping, Associative Mapping, Set-Associative Mapping), and Instruction Pipelining (Pipelining stages, Hazards — Structural, Data, Control hazards).
In VB.NET ADO.NET programming questions, always remember to write `con.Open()` before executing commands and `con.Close()` in a finally block to avoid losing marks for unclosed database connections.
Important Exam Focus: Cache Memory Mapping calculation comparing Direct, Associative, and Set-Associative mapping with address bit breakdowns; CPU Instruction Cycle with flowchart; Addressing Modes with diagram and memory operand location; Pipelining hazards.
