1) Define Data Structure. Explain different categories of Data Structure.
A **data structure** is a specialized way of organizing, storing, and managing data in a computer to enable efficient access, manipulation, and operations. It defines how data is stored and the relationships between data elements.
Data structures are categorized into two main types:
- **Primitive Data Structures**: Basic building blocks like integers, floats, characters, and booleans, which handle simple data types directly
...Explain instanciate/instance is a relationship.
In Artificial Intelligence and knowledge representation, the "instance" or "instantiates" relationship describes the connection between an individual object (an instance) and the class or concept (the type) it belongs to.
Explanation of Instance Relationship
- An **instance** is a specific object or entity that belongs to a broader category or class. For example, "Snoopy" is an instance of the class "Dog."
- The **instantiates** relation links this
Diagramma tensione-deformazione per l’acciaio
Prova di trazione
Nel tratto OP l’andamento è lineare: la deformazione è di tipo elastica. La pendenza del tratto retto definisce il modulo elastico E del materiale. Nel tratto PE iniziano a verificarsi deformazioni permanenti di lieve entità. Il punto E rappresenta il limite del campo elastico, oltre il quale avviene la deformazione plastica. Nel tratto ES si osserva un graduale passaggio dal campo elastico a quello plastico. Il punto S, detto
Chemistry uses math for measuring, calculating, and comparing data.
Uses SI Units (grams, liters, meters, kelvin, etc.).
Conversions are common (like grams to kilograms).
Accuracy and precision matter in all experiments.
Example: Measuring 25.0 mL of water = precise data.
Steps: Ask a question → Form a hypothesis → Experiment → Collect data → Analyze → Conclude.
Managing financial resources to achieve long-term organizational goals.
Integrating financial strategy with overall corporate strategy.
Financial Planning and Forecasting: Aligning financial goals with the strategic plan.
Investment Decisions (Capital Budgeting): Selecting long-term projects that align with strategic objectives.
Financing Decisions (Capital Structure): Determining the optimal mix of debt

## **1. a) Define Java Bytecode. Justify that Java is platform independent
**Java Bytecode** is the intermediate code generated by the Java compiler after compiling a Java program. When you write a Java source file (`.java`) and compile it using `javac`, the compiler converts it into a bytecode file (`.class`). This bytecode is not specific to any machine and can be executed by the **Java Virtual Machine (JVM)** on any platform.
**Platform independence** means that a Java program can run on any
...Cloud computing is a transformative technology that enables users to access computing resources over the internet rather than on physical devices or local servers. Below is a detailed note on cloud computing, covering key concepts, types, benefits, and use cases.
Cloud computing refers to the delivery of various services over the internet, including storage, processing, networking, databases, software, and more. It allows businesses and individuals to use computing resources...
