+### What is Natural Language Processing (NLP)?
+
+Natural Language Processing (NLP) is a field of Artificial Intelligence (AI) that focuses on the interaction between computers and humans through natural language. The goal of NLP is to enable machines to understand, interpret, generate, and respond to human language in a way that is both meaningful and useful.
+
+NLP combines computational linguistics, computer science, and machine learning to process and analyze large amounts of natural language data. It plays a vital role in applications such as:
+
+- **Text Classification** (e.g., spam detection)
+- **Sentiment Analysis**
+- **Machine Translation** (e.g., Google Translate)
+- **Speech Recognition**
+- **Chatbots and Virtual Assistants** (e.g., Siri, Alexa)
+- **Information Extraction and Retrieval**
+
+As technology continues to evolve, NLP is becoming increasingly powerful and is being applied across various domains such as healthcare, finance, education, and more.
