Study Notes

Exam Overview

The examination is conducted by the Rajasthan Public Service Commission for the post of Programmer in the Department of Information Technology and Communication.
It consists of two papers: Paper I and Paper II, each with 100 questions.

Paper I: Reasoning Test, Numerical Analysis, and General Knowledge

Focus on problem-solving techniques, data interpretation, data sufficiency, and logical reasoning.
General knowledge and current affairs concerning India and Rajasthan are significant components.
Database Management Systems encompass:
- ER diagrams and data models (relational and object-oriented).
- Conceptual database design and normalization.
- Distinctions between physical and logical databases alongside data abstraction.
- Essentials of SQL application development, including embedded SQL, stored procedures, triggers, and views.
Internal workings of RDBMS include:
- Physical data organization methods (sequential, indexed, random, hashed).
- Structures like B trees and B+ trees.
- Query optimization strategies and join algorithms.
- Transaction processing concepts, concurrency control, and recovery management.
- Lock-based protocols and two-phase locking.
Understanding Data Communication and Computer Networks:
- Different architectures such as circuit switching and packet switching.
- Layers of networks, including physical and data link layers.
- TCP/IP stack, IP networks, internet fundamentals, and secure communication through firewalls and intrusion detection.

Paper II: System Analysis and Design

Core system concepts include definitions, characteristics, elements, and boundaries.
Types of system development lifecycle and initial requirements analysis including feasibility studies.
Tools for system planning: DFD, data dictionaries, decision trees, and structured analysis.
Software Life Cycle stages and methodologies in software engineering paradigms.
System analysis methods emphasizing feasibility, requirement analysis, and cost-benefit analysis.
System design involves modular design, data and procedural design, and object-oriented design principles.
Software development focuses on efficient code documentation, design paradigms, and the verification of programs.
Maintenance considerations include characteristics, tasks, and potential side effects.

Programming Concepts

Introduction to internet applications using Java and understanding byte code benefits.
Object-oriented programming (OOP) principles covering abstraction, encapsulation, inheritance, and exceptions.
Java programming fundamentals include topics like variables, control flow, method overloading, and file I/O.
Advanced Java concepts encompass working with arrays, strings, vectors, and derived classes.
Knowledge of JSP, RMI, Java applets, and servlets, along with the DotNet framework and visual programming interfaces.

Exam Details

Total duration for each paper is 2 hours, with a total of 200 marks available across both papers.
Negative marking policy: One-third of the marks will be deducted for incorrect answers.
Each question includes five options, and candidates must shade only one circle indicating their answer.
A missed question without an answer marked will result in a deduction of one-third of the marks if more than 10% of questions are unanswered.
Extra time of 10 minutes is granted post the scheduled duration to double-check answers.
