BIOS Interrupts

BIOS (Basic Input/Output System) interrupts are low-level routines provided by the system’s firmware to perform hardware-related operations. These interrupts are invoked using the INT instruction in assembly language and are essential for tasks like reading from or writing to hardware devices.

Common BIOS Interrupts:

• INT 10h: Video services (e.g., setting video mode, cursor position)
• INT 13h: Disk services (e.g., reading/writing sectors)
• INT 16h: Keyboard services (e.g., reading keystrokes)
• INT 17h: Printer services
• INT 1Ah: Real-time clock services

These interrupts are primarily used in real-mode operations and are crucial during the boot process before the operating system takes over hardware control.

Theory of Computation (TOC) – GATE Previous Year Questions

Theory of Computation is a fundamental subject in computer science, dealing with the mathematical aspects of computing. It encompasses topics like automata theory, formal languages, and computability.

Key Topics in TOC:

• Finite Automata: Deterministic (DFA) and Non-Deterministic (NFA)
• Regular Expressions and Languages
• Context-Free Grammars (CFG) and Pushdown Automata (PDA)
• Turing Machines
• Decidability and Undecidability
• Pumping Lemma for Regular and Context-Free Languages

GATE TOC Previous Year Questions:

To effectively prepare for GATE, practicing previous year questions is invaluable. Here are some resources where you can find TOC questions from past GATE exams:

Study Tips for GATE TOC:

1. Understand the Fundamentals: Grasp the core concepts of automata, grammars, and Turing machines.
2. Practice Regularly: Solve a variety of problems to strengthen your understanding.
3. Use Visual Aids: Draw state diagrams for automata and parse trees for grammars to visualize problems.
4. Review Mistakes: Analyze errors in practice problems to avoid them in the future.
5. Time Management: Practice solving questions within a set time to simulate exam conditions.
