Welcome to this comprehensive PySpark tutorial! In this video, we'll cover essential PySpark concepts, perfect for beginners, working professionals, and those preparing for interviews. Here's what you'll learn:

Apache Spark is an open-source, distributed computing system designed for fast processing of large datasets using clusters of computers. Distributed computing involves splitting a large problem into smaller tasks, processing them across multiple machines (nodes), and then aggregating the results. PySpark is the Python API for Apache Spark, enabling efficient big data processing and analysis with Python.

**Topics Covered:**
- Introduction to Apache Spark and PySpark
- Distributed Computing with PySpark: A Word Count Example
- Creating and Manipulating DataFrames
