Networking Fundamentals: Models, Protocols, and Topologies
Core Networking Concepts Summarized
Here are short notes on four fundamental topics in computer networking:
- OSI Model: The Open Systems Interconnection (OSI) model is a conceptual framework that standardizes network communication into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It aids in understanding and troubleshooting network protocols.
- TCP/IP Model: The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a practical networking model
Kinematics of Projectiles: Motion, Trajectory, and Formulas
Kinematics of Projectile Motion
Defining Projectiles
- Projectiles are bodies projected into the air that possess both horizontal and vertical components of motion.
- Examples include: shot put, discus, javelin, and the human body during a jump.
- Gravity determines the maximum height achieved by the projectile.
- The horizontal component determines the maximum distance (range) the projectile reaches.
- In real-world scenarios, only air and wind resistance significantly affect the projectile’s motion.

Auditing Procedures for Healthcare, Hospitality, and Co-operative Societies
Auditing Healthcare Organizations
Healthcare Organizations primarily include hospitals and nursing homes. They are established to provide medical services to the public. These organizations may be run and funded by the Government, local authorities, or charitable trusts, and are generally non-profit seeking.

Diabetes Mellitus: Definition and Classification
Diabetes Mellitus (DM) is a chronic disease associated with poor or non-functional production of insulin in the pancreas. This syndrome is characterized by hyperglycemia, altered metabolism of carbohydrates, lipids, and proteins, and an increased risk of vascular complications.
Clinical Classification of Diabetes
DM is clinically classified as:
- Type 1 Diabetes (IDDM): Insulin-Dependent Diabetes Mellitus.
- Type 2 Diabetes (NIDDM): Non-Insulin-Dependent Diabetes
