The nervous system is the body's communication network, a complex system of nerves and cells (neurons) that carry signals to and from the brain and spinal cord to different parts of the body. It is divided into two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
Structure and Types of Neurons
Neurons are the fundamental building blocks of the nervous system. They are specialized cells that transmit electrical and chemical signals. While they can vary in size and...
Comparative Politics: Conceptual Understanding (400 words)
Comparative Politics is a subfield of political science that involves the systematic study and comparison of political systems, institutions, processes, and behavior across different countries. Its primary aim is to identify patterns, similarities, and differences in how political power is organized and exercised globally.
At its core, comparative politics seeks to answer fundamental questions: Why do some countries have stable democracies...
Analytical techniques are methods used to identify, quantify, and understand the chemical composition and structure of substances. These techniques are broadly classified into qualitative (what is present) and quantitative (how much is present) methods. Common analytical techniques include:
1. Gravimetric Analysis
Involves measuring the mass of a substance to determine the amount of analyte.
Titrimetric (Volumetric) Analysis
Based on measuring the volume of a standard solution required to react...

| Asks if a salt (like NaClO) is acidic, basic, or neutral | Conjugate acid-base salt classification |
| Involves a weak acid concentration and asks for pH | Weak acid equilibrium problem (ICE table + Ka) |
| Involves a salt of a weak acid (like NaC₆H₅CO₂) and asks for pH | Basic salt hydrolysis problem (conjugate base + Kb) |
Strong acid + strong base → neutral salt
🔧 1. Software Maintenance & Evolution
Q1: Explain the four types of software maintenance with examples.
There are four primary types of software maintenance: Corrective, Adaptive, Perfective, and Preventive. Corrective maintenance focuses on fixing errors or bugs in the software, such as patching a login failure. Adaptive maintenance involves updating the software to accommodate changes in the environment, like upgrading compatibility for a new operating system. Perfective maintenance enhances...

1. Explain the concept of Object-Oriented Programming (OOP) in Java.
Java is a fully object-oriented programming language that follows the core principles of Object-Oriented Programming (OOP): encapsulation, inheritance, polymorphism, and abstraction. In Java, everything is treated as an object, which makes it easy to model real-world scenarios. Encapsulation is achieved using access modifiers and getter/setter methods, ensuring that data is protected from unauthorized access. Inheritance allows...
