The generations of the computer

FOURTH GENERATION (1971 TO 1981)

LSI large scale integration circuit is born

memory of magnetic rings is replaced by memory of silicon chips

each chip can do different tasks

more circuits are placed inside a chip

microprocessor was developed

SECOND GENERATION (1959-1964)

the programs that were used during the first generation were improved

were used in applications for airline reservation systems, air traffic control

new programming languages such as COBOL and FORTRAN were developed

they used small magnetic rings to store information

used transistors to process information

|

FIFTH GENERATION AND ARTIFICIAL INTELLIGENCE (1982-1989)

is known as communication networks like hardware and software

supercomputers are developed

microcomputers, personal computers or PCs are developed

the development of software and the systems with which computers are managed

THIRD GENERATION (1964-1971)

they become smaller, lighter and more efficient

processors can perform both mathematical processing and analysis tasks

software industry emerges

multiprogramming arises

chips were developed to store information

integrated circuits were developed to process information

FIRST GENERATION (1951 TO 1958)

they were very big

they were extremely slow

they used a lot of energy

used punch cards to enter data and programs

used magnetic cylinders to store information

they used vacuum tubes to process information
