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:

- ExamSide – TOC GATE Questions:
- GATE Overflow – TOC Questions:
These platforms provide a collection of questions categorized by topics, along with detailed solutions and explanations.
Study Tips for GATE TOC:
- Understand the Fundamentals: Grasp the core concepts of automata, grammars, and Turing machines.
- Practice Regularly: Solve a variety of problems to strengthen your understanding.
- Use Visual Aids: Draw state diagrams for automata and parse trees for grammars to visualize problems.
- Review Mistakes: Analyze errors in practice problems to avoid them in the future.
- Time Management: Practice solving questions within a set time to simulate exam conditions.
