Dispatch latency refers to the time it takes for the dispatcher to stop one process and start another running. This includes the time it takes to switch context, to switch to user mode, and to jump to the proper location in the newly loaded program. This is a crucial aspect in multitasking operating systems and directly impacts the system's performance.

Here are the steps:

1. The dispatcher first stops the execution of the current running process.
2. Then, it saves the state of the current process, also known as context switching. The state includes the values in the processor's registers, program counter, etc.
3. The dispatcher then loads the state of the next process to be executed. This is the reverse of step 2, where the saved state of the process is loaded back to the processor's registers.
4. The dispatcher switches the CPU to user mode.
5. Finally, the dispatcher jumps to the proper location in the newly loaded program to start its execution.

This entire process is known as dispatch latency.
