-
Period: to
1st generation
-Vacuum tubes (small wire tube)
-Used magnetic drums for memory
-Lot of energy
-Information was displayed in bulbs (bulb=bit. if it was 1 was on, and if it was 0 it was off)
-The computers were enormous, each one occupied three rooms
-They required 24 hours of attention -
Period: to
2nd generation
-Transistors
-The invention of the transistor replaced the vacuum tubes and ashed in the 2nd generation of computers
-Were faster, cheaper and smaller, more energy efficient and more reliable than the 1st generation
-In this generation was created the first computer game, called Spacewar -
Period: to
3rd generation
-Was invented the microchip, a transistor which in each one had a complete circuit inside
-Had integrated circuit. Its development was the homework of the third generation.
-The transistors were miniaturized and placed on a silicon chip called the semiconductor, which increased the speed and efficiency -
Period: to
4th generation
-In this generation thousands of integrated circuits were built onto a single silicon chip
-It worked faster, and were cheaper and smaller.
-One microprocessor=10 millions of transistors.
-Internet was introduced on the computers -
Period: to
5th generation
-Computers have come a long way today, and will continue to do, so thanks to artificial intelligence (AI) technology, which will solve all kinds of tasks.
-There're robots now.
-They'll change the actual screams to 3D technology
