Google Colab, short for Google Collaboratory, is a powerful cloud-based platform designed for data science and machine learning projects. It provides a Jupyter Notebook environment that allows users to write, run, and share code seamlessly without the need for local installations. With access to pre-installed libraries such as TensorFlow and PyTorch, users can quickly start their machine learning experiments. Google Colab is free to use and supports GPU and TPU acceleration, making it an ideal choice for both beginners and experienced practitioners in the field of AI and data science. Its collaborative features further enhance teamwork and project sharing.
