The first device similar to a modern computer can be traced back to the middle of the 20th century (1940–1945), although the concept of computer and various computer-like machines existed earlier. Early electronic computers were as big as a big room, and consumed energy equivalent to that of hundreds of modern personal computers (PCs). [1] Modern computers are based on tiny integrated circuits, and their capabilities are improved by millions to billions of times while occupying a small space. [2] Today, a simple computer can be made small enough to fit into a watch and be powered by the battery of the watch. Personal computers in various forms are the symbol of the information age, and they are considered as "a computer" by most people. However, the most commonly used computer form today is embedded computer. Embedded computers are small and simple devices used to control other devices. For example, they can be found in machines ranging from fighter planes to industrial robots, digital cameras and children's toys.
There is a translator:
A computer is a list of machine operation data according to instructions.
The first equipment, like modern computers, can be traced back to the middle of the 20th century (1940- 1945), although the concept of computers and various devices are similar to those before computers. Early electronic computers were as big as a big room, consuming more energy for hundreds of modern personal computers (PCs). [1] Modern computers are based on micro-integrated circuits, which are several million to several billion times more powerful and occupy a small part of space. [2] Today, a simple computer can be small enough to fit into a watch and be powered by the battery of the watch. Personal computer, with different forms, is a symbol of the information age and a "computer" that many people think. However, the most commonly used computer today is the embedded computer. Embedded computers are small and simple devices used to control other devices, for example, they may be discovered.
