Java Exceptions: Checked vs Unchecked

Differentiating Exception Types in Java

Exceptions in Java are runtime errors that disrupt the normal flow of a program. They are classified into checked and unchecked exceptions.

Checked Exceptions are verified at compile time. The programmer must either handle them using try-catch blocks or declare them using the throws keyword. These exceptions usually occur due to external factors such as file handling, database access, or network issues. Examples include IOException,

🧠 useEffect Cheat Sheet (Beginner → Confident)

1️⃣ What is useEffect? (Plain English)

👉 Side effects = things that are not UI rendering.

  • Fetching data
  • Calling APIs
  • Using localStorage
  • Timers (setTimeout, setInterval)
  • Event listeners
  • Updating the document title

Rule of thumb:
If it touches the outside world, it belongs in useEffect.

2️⃣ Basic Syntax (Memorize This)

useEffect(() => {
  // side effect code
}, [dependencies]);

📌 Two parts:

Virtualization Levels and Hardware Implementation

4. List and briefly describe the levels of virtualization. Describe in detail how virtualization works at the hardware / OS level. Virtualization can be implemented at different levels, depending on what part of the system is abstracted. The lecture classifies virtualization levels as: application level, library/user-level API, operating system level, hardware abstraction (HAL) level, and instruction set architecture (ISA) level. Each level virtualizes
