Building a Computer – Six Things You Ought to Know

By the late 1930′s punched-card machine techniques had become so

collaboration with engineers at IBM, undertook construction of a large automatic digital computer based on standard IBM electromechanical parts.; Aiken’s machine, called the Harvard Mark I, handled 23-digit numbers and could perform all four arithmetic operations.; Also, it had

ENIAC was thus about 1,000 times faster than the previous generation of computers (Dolotta, 47).

task he wanted the computer to do.; It was, however, efficient in handling the particular programs for which it had been designed.; ENIAC is generally accepted as the first successful high-speed electronic digital computer and was used in many applications from 1946 to 1955

future generations of high-speed digital computers and were universally adopted (Hall, 73).

computers required considerable maintenance, usually attained 70% to 80% reliable operation, and were used for 8 to 12 years.; Typically, they were programmed directly in machine language, although by the mid-1950s progress had been made in several aspects of advanced programming.; This group of machines included EDVAC and UNIVAC, the first commercially available computers (Hazewindus, 102).

Early in the 1950s two important engineering discoveries changed the electronic computer field.; The first computers were made with vacuum tubes, but by the late 1950′s computers were being made out of transistors, which were smaller, less expensive, more reliable, and more efficient (Shallis, 40).; In 1959, Robert Noyce, a physicist at the Fairchild Semiconductor Corporation, invented the integrated circuit, a tiny chip of silicon that contained an entire electronic circuit.; Gone was the bulky, unreliable, but fast machine; now computers began to

expensive to purchase or to rent and were especially expensive to operate because of the cost of hiring programmers to perform the complex operations the computers ran.; Such computers were typically found in large computer centres–operated by industry, government, and private

During this time the major computer manufacturers began to offer a range of computer capabilities, as well as various computer-related equipment.; These included input means such as consoles and card feeders output means such as page printers, cathode-ray-tube displays,

also used in automated library systems and in database systems such as the Chemical Abstracts system, where computer records now on file cover nearly all known chemical compounds (Rogers, 98).

invented the microprocessor and another stage in the development of the computer began (Shallis, 121).

A new revolution in computer hardware was now well under way, involving miniaturization of computer-logic circuitry and of component manufacture by what are called large-scale integration techniques.; In the 1950s it was realized that “scaling down” the size of electronic

computer, the IBM Model 60 in 1975 (Chposky, 156).; However, the newly formed Apple Computer company was releasing its own personal computer, the Apple II (The Apple I was the first computer designed by Jobs and Wozniak in Wozniak s garage, which was not produced on a wide scale).; Software was needed to run the computers as well.; Microsoft developed a

The main goal of the computer manufacturers was to make the computer as affordable as possible while increasing speed, reliability, and capacity.; Nearly every computer manufacturer accomplished this and computers popped up everywhere.; Computers were in businesses keeping track of inventories.; Computers were in colleges aiding students in research.; Computers were in laboratories making complex calculations at high speeds for scientists and physicists.; The computer had made its mark everywhere in society and built up a huge industry (Cringley, 174).
