The CPU executes the program The CPU loads the registers with the appropriate data. The CPU executes thread When the CPU has to execute a thread, it first has to load the registers with the appropriate data for the thread. This process is repeated every time the CPU swaps between threads, in other words when it’s implementing multi- threading. Hyper-threading Hyper-threading

Internet browser Music player Word processor Display output Edit text Insert image The CPU executes thread Intel processors that implement hyper-threading have an extra set of registers so that the data does not need to be loaded into the same set of registers and can be accessed immediately by the other thread. This saves a lot of time and the operating system is “fooled” into believing that there is a second processor core when there isn’t actually one.
