FIRST COMPUTER
The first computer was invented by Charles Babbage (1822) but was not built until 1991 -
CREATION OF ENERGY
- Computeres began using electric power
-
Period: to
FIRST GENERATION COMPUTERS
- The computers used a lot of electricity
- The computers where very big
- Used vacumm tubes (It is used as a switch, amplifier or display screen)
-
Period: to
SECOND GENERATION COMPUTERS
- Replaced vacuum tubes with transistors, (used for amplifying, controlling, and generating electrical signals)
- The computers became faster, smaller and cheaper
-
TRANSISTOR
The transistor was at work in the computer by 1956. Along with early advances in magnetic-core memory, transistors led to second generation computers that were smaller, faster, more reliable and more energy-efficient than their predecessors. -
Period: to
THIRD GENERATION COMPUTERS
- Intergrated circuit as small as a transistor.
- Intergrated circuits where used for video processors, computer memory, switches, and microprocessors.
- Computers became faster, smaller and cheaper
-
INTERGRATED CIRCUIT
The third generation was brought about by advances in the manufacture of transistors; they where able to make transistors smaller , which led to entire circuits fitting onto a single piece of silicon, now known as the integrated circuit or microchip -
Period: to
FOURTH GENERATION COMPUTERS
- The placement of many more components on a chip: Micro processor
- The computers became smaller, and portable, they consumed less electricity. (Less heat)
-
VLSI technology
VLSI is mainly used to design electronic components like microprocessors and memory chips, which require millions of transistors. -
Period: to
FIFTH GENERATION COMPUTERS (FUTURE)
- The computers will think on there on (Artificial intelligence).
- They will have a digital camera and a digital keyboard.
- These computers will be faster, more intelligent.
