The CompTIA A+ 1101 exam includes various types of virtualization, each with unique purposes. Client-side virtualization runs on desktops or workstations, allowing users to create isolated environments for testing software and configurations safely. This method is popular among developers for secure application testing and enables compatibility between older software and newer hardware. It also allows applications from different operating systems to run on others, like Windows programs on macOS or Linux.

Virtualization allows multiple operating systems to run on one physical machine by creating virtual IT resources like servers and storage. Benefits include improved hardware use, reduced costs, faster system deployment, better workload portability, and enhanced security through isolated environments. Using fewer physical servers for multiple virtual machines lowers hardware and operational costs, while virtualization's flexibility supports rapid deployment and easy migration, making IT environments more adaptable to business needs.
