The generations of the computer

they used vacuum tubes to process information

used magnetic cylinders to store information

used punch cards to enter data and programs

they used a lot of energy

they were extremely slow

they were very big

integrated circuits were developed to process information

chips were developed to store information

multiprogramming arises

software industry emerges

processors can perform both mathematical processing and analysis tasks

they become smaller, lighter and more efficient

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

microcomputers, personal computers or PCs are developed

supercomputers are developed

is known as communication networks like hardware and software

used transistors to process information

they used small magnetic rings to store information

new programming languages such as COBOL and FORTRAN were developed

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

the programs that were used during the first generation were improved

microprocessor was developed

more circuits are placed inside a chip

each chip can do different tasks

memory of magnetic rings is replaced by memory of silicon chips

LSI large scale integration circuit is born
