#A computer is a modern intelligent electronic device that can automatically and quickly perform large-scale numerical calculations and various information processing according to pre-stored programs.
is composed of hardware and software, and the two are inseparable. A computer without any software installed is called a bare metal computer. (Recommended study:phpstorm)
With the development of science and technology, some new computers are now emerging: biological computers, photon computers, quantum computers, etc.
Supercomputer
Supercomputers usually refer to computers composed of hundreds, thousands or even more processors (computers) that can calculate A computer for large and complex projects that ordinary PCs and servers cannot complete. A supercomputer is a type of computer with the most powerful functions, the fastest computing speed, and the largest storage capacity. It is an important symbol of the country's scientific and technological development level and comprehensive national strength.
Personal Computer
Desktop
Also called desktop, it is an independent computer , completely unrelated to other components. Compared with notebooks and netbooks, they are larger in size. Hosts, monitors and other equipment are generally relatively independent and generally need to be placed on a computer desk or a special workbench. Hence the name desktop. It is a very popular microcomputer, and most of the machines used in people's homes and businesses are desktop computers. The performance of desktop computers is relatively stronger than that of laptop computers.
Notebook or Laptop
Also known as laptop computer or laptop computer, it is a small, portable personal computer, usually weighing 1- 3kg. In addition to the keyboard, the laptop also provides a touchpad (TouchPad) or a touch point (Pointing Stick), which provides better positioning and input functions.
Tablet computer
Tablet computer is a computer that does not need to be flipped, has no keyboard, comes in different sizes and shapes, but has complete functions. Its components are basically the same as those of a laptop, but it uses a stylus to write on the screen instead of using a keyboard and mouse for input, and breaks the J-shaped design pattern of laptop keyboards that are perpendicular to the screen.
Embedded Computer
Embedded Systems are application-centered, microprocessor-based, and software and hardware can be tailored. , a special computer system that adapts to the comprehensive and strict requirements of application systems on function, reliability, cost, volume, power consumption, etc.
It generally consists of four parts: embedded microprocessor, peripheral hardware devices, embedded operating system and user application program.
