How big was the world's first computer?

The world's first computer weighed 30 tons and covered an area of ​​160 square meters.

On February 14, 1946, the world's first computer, named INIAC, was born at the University of Pennsylvania in the United States.

During World War II, the U.S. military asked Dr. Mauch of the University of Pennsylvania and his student Eckert to design an "electronic" computer that used vacuum tubes to replace relays - the ENIAC, which was intended to calculate the trajectory of artillery shells.

The machine used 18,800 vacuum tubes, was 50 feet long, 30 feet wide, took up 1,500 square feet, and weighed 30 tons. It had a high calculation speed, capable of performing 5,000 addition operations per second, and operated for nine years.

What is a computerized system?

Computerized system refers to the combination of controlled system, computer control system and human-machine interface. Various activities involved in its life cycle, such as verification, maintenance, management, etc., require close cooperation between personnel of relevant functional departments. Personnel whose duties involve the use and management of computerized systems should receive corresponding use and management training. Ensure that there are appropriate professionals to provide training and guidance on the design, verification, installation and operation of computerized systems. Computerized systems can replace manual operations and improve work efficiency, but the risks brought about by such replacement or change need to be considered. Such risks may come from product quality, process control, or the entire quality assurance system. The many impacts brought about by such changes need to be carefully and comprehensively considered. In principle, the overall risk should not be increased compared with the manual operation in the past. As long as there are changes, risk identification and risk assessment must be done well. This is the premise and rigid requirement of all "changes".

What are the characteristics of a computer?

The characteristics of computers include: fast computing speed, high computing accuracy, large storage capacity, high reliability, etc. Computers are commonly known as computers. They are modern electronic computing machines used for high-speed computing. They can perform numerical and logical calculations and have storage and memory functions. They are modern intelligent electronic devices that can run according to programs and automatically and quickly process massive amounts of data.

John von Neumann, inventor of the computer. The computer is one of the most advanced scientific and technological inventions of the 20th century. It has had a very important impact on human production and social activities, and has developed rapidly with strong vitality. Its application areas have expanded from the initial military scientific research applications to all areas of society, forming a huge computer industry, driving technological progress on a global scale, and thus triggering profound social changes. Computers have spread to general schools, enterprises and institutions, and entered ordinary people's homes, becoming an indispensable tool in the information society.
