6、 The Evolution of Computer Age,The Computer Age did not really begin until the first computer was made available to the public in 1951. The modern age of computers spans almost 50 years, which is typically broken down into five generations. Each generation is marked by a significant advancement in t
7、echnology:,Text A: The Evolution of Computer Age,First Generation(The Vacuum Tube Age 1951-1957):,During this generation, computers were built with vacuum tubeselectronic tubes that were made of glass and were about the size of light bulbs. These computers were expensive and bulky. They used machine
8、 language for computing and could solve just one problem at a time. In the year 1951, the first commercially available electronic digital computer was introduced to the public, which marked the first generation computers came into being. IBM (International Business Machines Corporation), today a big
9、 name in the list of computer technology industries, announced the IBM 702 Electronic Data Processing Machine in 1953. It was developed for business use and could address scientific and engineering applications.,Text A: The Evolution of Computer Age,Second Generation (The Transistor Age 1958-1963),T
10、his generation began with the first computers built with transistorssmall devices that transferred electronic signals across a resistor. Because transistors were much smaller, use less power, and created less heat than vacuum tubes, the new computers were faster, smaller, and more reliable than the
11、first-generation machines were. In the 1960s, transistor based computers replaced vacuum tubes. Transistors made computers smaller and cheaper. They made computers energy-efficient. The use of transistors marked the second generation of computers.,Text A: The Evolution of Computer Age,Third Generati
12、on (The Integrated Circuit Age 1964-1969),In 1964, computer manufacturers began replacing transistors with integrated circuits. An integrated circuit (IC) is a complete electronic circuit on a small chip made of silicon. These computers were more reliable and compact than computers made with transis
13、tors, and they cost less to manufacture. Whats more, the use of the new types of computer increased the speed and efficiency of computers. In the year 1965, Digital Equipment Corporation (DEC) introduced the first minicomputers.,Text A: The Evolution of Computer Age,Fourth Generation (The Microproce
14、ssor Age 1970-1990),There were many key advancements that were made during this generation, the most significant of which was the use of the microprocessor a specialized chip developed for computer memory and logic. This revolutionized the computer industry by making it possible to use a single chip
15、 to create smaller personal computers. Microprocessors came up during the 1970s. Intel produced large-scale integration circuits in 1971. Apple Computer, Inc., founded by Steve Wozniak and Steve Jobs, brought out the Macintosh personal computer in 1984. Microsoft, a company founded by a young Harvar
16、d drop-out named Bill Gates, who wrote the programming language BASIC for one of the earliest microcomputers, introduced their Windows graphical user interface in the year 1985.,Text A: The Evolution of Computer Age,Figure 1. Minicomputer,Figure 2. Microcomputer,Text A: The Evolution of Computer Age,Fifth Generation (The Age of Connectivity 1990 and beyond),Our current generation has been referred to as “Connected Generation” because of the industrys massive effort to inc
