Operating systems are great at multi-tasking but they never asked what you want. They assume you want all of the installed applications at the same time when you just wanted to open a word document.

Fast! technology is doing what you want by making sure all of the other processes in the system will not get in your way - focusing all of the system resources for you.

Some history: when Microsoft designed the current windows architecture, about 25 years ago, they focused on process multi-tasking, less on user actions. When Steve Jobs created the iPhone - he disabled applications multi-tasking just to make sure the single application experience is great.

Central Processing Unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The computer industry has used the term "central processing unit" at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.

Fast! is reducing the calls to the CPU from any application, process or thread that are not a part of what you want.

Random-access memory (RAM) is a form of computer data storage which stores frequently used program instructions to increase the general speed of a system. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.

Virtual memory is a memory management technique that is implemented using both hardware and software. It maps memory addresses used by a program, called virtual addresses, into physical addresses in computer memory. Main storage as seen by a process or task appears as a contiguous address space or collection of contiguous segments. The operating system manages virtual address spaces and the assignment of real memory to virtual memory.

Each is assigned to a Virtual Memory of several gigabytes - which does not really exist, it's virtual. Only a part of the required memory is stored in the memory chips, the rest is sent back to the hard drive, the slowest component in the system.

Fast! is managing the memory differently to maximize the system speed by prioritizing RAM memory for actions that you want.
