Client virtualization involves installing an application on a server and enabling multiple users to run the application simultaneously via virtualized sessions. This eliminates the need for individual installations on local machines.
* Why Not B (Software as a Service): SaaS delivers software over the internet and does not require local installations but is managed by a third party, not the organization itself.
* Why Not C (Sandboxing): Sandboxing is for isolating applications for security testing, not for concurrent user access.
* Why Not D (Embedded software): Embedded software is installed on hardware devices, not shared across multiple users.
