If your talking about a video game switching to CPU is switching that person to a computer.
CPU switching from process to another
Process switching is an operation that provides full route evaluation and per-packet load balancing across parallel WAN links. Process switching involves the transmission of entire frames to the router CPU, where they are repackaged for delivery to or from a WAN interface, with the router making a route selection for each packet. Process switching is the most resource-intensive switching operation that the CPU can perform.

In process switching the CPU is required to be personally involve with every forwarding decision. Process switching is similar to doing long math versus doing it the quick way.
Context switching is the process of saving the state of a process or thread, and then restoring the state of another process or thread for execution. Context switching enables multitasking by allowing multiple processes or threads to share a single CPU. It involves saving and restoring CPU registers, program counter, and stack pointers.

Time-sharing is designed so that rapid switching between tasks allows the users to believe they have sole use of a scarce resource (CPU). If there is only 1 CPU present then only 1 task can run at a time. With rapid switching it occurs so quickly that it appears as though multiple jobs (tasks) are being serviced.
Context switching between kernel threads typically requires saving the value of the CPU registers from the thread being switched out and restoring the CPU registers of the new thread being scheduled.
Context switching is how the computer's operating system multitasks different processes. It lets one process run for a while and then saves a copy of the process' run state (such as register values) off to the side, restores the run state of the next process back into the processor, and runs it for a while. Context switching is this process of swapping one program out of the CPU and replacing it with another process.

The principal disadvantge of too much multiprogramming is the overhead of excesssive context-switching. If the context-switch rate is too high, the overhead can actually overwhelm the benefit of multiprogramming.
