**What is Virtualization?**\
Virtualization is a technology that allows you to create multiple simulated environments or virtual machines (VMs) on a single physical machine. Each VM operates like an independent computer with its own operating system and resources, but they share the underlying hardware of the host system.

**Role of Virtualization in Creating Labs**\
In educational or professional settings, virtualization is essential for creating labs. It allows users to:
- Simulate real-world environments: Students and professionals can practice complex configurations, test software, or run different operating systems without needing multiple physical machines.
- Isolate environments: Each VM is isolated, meaning experiments or tests in one environment won’t affect others. This is crucial for cybersecurity labs where malware or unsafe configurations might be tested.
- Efficient resource use: By sharing a host machine's resources, virtualization reduces the need for additional hardware, making it cost-effective and scalable for lab setups.

Tools like Oracle VirtualBox make it easy to create, manage, and switch between multiple virtual environments on a single machine, which is ideal for training and experimentation.
