Computer profile:
Computers, also known as computers and electronic computers. It is a machine that uses electronic principles to process data according to a series of instructions.
In modern times, the application of mechanical computers has been completely replaced by electronic computers, so electronic computers are usually referred to as computers for short. Related technical research is called computer science, and data-centered research is called information technology. Usually, people are most exposed to personal computers.
Computers and Internet:
After 1970s, computer engineers in American universities began to use telecommunication technology to connect their computers. Because this work is sponsored by ARPA, its computer network is also called ARPANET.
Since then, the technology used in ARPA network has spread and evolved rapidly, and this network has also broken through the scope of universities and teams, and finally formed today's Internet. The appearance of network leads to the redefinition of computer attributes and boundaries. John gage and Bill Joy of Sun Microsystems pointed out that "the network is the computer".
Computer operating systems and applications are developing towards accessing network resources, such as other computers in the network.
At first, these network devices were only used by high-end scientists, but after the 1990s, with the popularity of e-mail and World Wide Web technologies and the cheapness of network connection technologies such as Ethernet and ADSL, the Internet has become ubiquitous.
Why are tens of millions of computers connected to the Internet today? With the popularization of wireless interconnection technology, the Internet in mobile computing environment is also closely followed. For example, Wi-Fi technology widely used in notebook computers is a representative application of wireless Internet access.
