Microcomputers
Microcomputers, also named personal computers, represent the class that is currently the most widely used (at school, workplace, home). There are several types of microcomputers:
Mobile devices include:
* * Laptops, Palmtop computers, notebook computers – made for mobile use, varying sizes
* Tablet computer – miniaturized laptops with touch-screen technology.
* Smartphones, smartbooks, PDAs – designed for being portable, little computing power.
* Programmable calculator – specialized on mathematical purposes.
* Handheld game consoles – designed for entertainment and mobile use
Minicomputers
A minicomputer represents the type that stands in the middle range of the computing spectrum. In our days this class of computers is named midrange. E.g. - Laboratory computers.
Mainframe computers
“The term mainframe computer was created to differentiate the traditional, large, institutional computer intended to service multiple users from the smaller, single-user machines. This class of computers is able to handle and process very large amounts of data quickly. They are measured in MIPS.”(2012, Wikipedia)
Supercomputer
A supercomputer is the most powerful regarding of memory size, speed, computational
