The correct answer is Embedded computer.About Embedded Computer An embedded computer is an integral component of most embedded systems.It is a combination of hardware and software that is designated to perform a highly specific function.The hardware of an embedded computer is also specially designed to withstand stresses in its intended environment.For example, the type of embedded computer in a washing machine will not be the same as the embedded computer in a Nikon camera.Other examples include digital watches, mobile phones, music players, specialist IT hardware (such as networking hardware), and almost any kind of industrial or domestic control system. A Mainframe computer is a big centralized machine that contains large memory, huge storage space, multiple high-grade processors, so it has ultra-processing power compared to standard computer systems.The mainframe computer systems importance is increasing for large-scale organization, scientific research, consumer statistics, and census data because it is capable to execute multiple complex programs concurrently at ultra-speed.UNIVAC I (UNIVersal Automatic Computer I) mainframe computers were first developed by J. Presper Eckert and John Mauchly in the USA, in 1951.A Supercomputer is a computer that performs at or near the currently highest operational rate for computers.A Supercomputer, any of a class of extremely powerful computers, is commonly applied to the fastest high-performance systems available at any given time.Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations.Two supercomputers from India ” PARAM Siddhi-AI and Mihir.These two supercomputers have made it to the TOP500 list of the worlds most powerful supercomputers. The two systems have been ranked 63rd and 146th, respectively.The Japanese supercomputer, Fugaku, is the world's most powerful Supercomputer.A Notebook computer is a battery or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces.
