History of the first servers used for web hosting

Computer used to mean a human being that did computations, but now the term almost universally refers to automated electronic machinery. The first computers were used primarily for numerical calculations. However, as any information can be numerically encoded, people soon realized that computers are capable of general-purpose information processing The computer’s capacity to handle large amounts of data has extended the range and accuracy of weather forecasting.

Their speed has allowed them to make decisions about routing telephone connections through a network and to control mechanical systems such as automobiles, nuclear reactors, and robotic surgical tools. They are also cheap enough to be embedded in everyday appliances and to make clothes dryers and rice cookers “smart.”

Computers have allowed us to pose and answer questions that could not be pursued before.. Increasingly, computers can also learn and adapt as they operate.
Computers also have limitations, some of which are theoretical. For example, there are undividable propositions whose truth cannot be determined within a given set of rules, such as the logical structure of a computer.

Because no universal method can exist to identify such propositions, a computer asked to obtain the truth of such a proposition will (unless forcibly interrupted) continue indefinitely—a condition known as the “halting problem Other limitations reflect current technology. Human minds are skilled at recognizing spatial patterns—easily distinguishing among human faces, for instance—but this is a difficult task for computers, which must process information sequentially, rather than grasping details overall at a glance. Another problematic area for computers involves natural language interactions.

Therefore, so much common knowledge and contextual information is assumed in ordinary human communication, researchers have yet to solve the problem of providing relevant information to general-purpose natural language programs. Although research is still being done.

During the 1950s and '60s, Unisys (maker of the UNIVAC computer), International Business Machines AKA IBM, and other companies made large, expensive computers of increasing power. They were used by major corporations and government research laboratories, typically as the sole computer in the organization. In 1959 the IBM 1401 computer rented for $8,000 per month (early IBM machines were almost always leased rather than sold), and in 1964 the largest IBM S/360 computer cost several million dollars.

These computers came to be called mainframes, though the term did not become common until smaller computers were built. Mainframe computers were characterized by having large storage capabilities, fast components, and powerful computational abilities. They were highly reliable, and, because they frequently served vital needs in an organization, they were sometimes designed with redundant components that let them survive partial failures. Because they were complex systems, they were operated by a staff of systems programmers, who alone had access to the personal computers. It is amazing how rapidly computers have changed over the past years.
