Grow old with you...

So let me assemble our computer
Put you to seat when you've had too much to type
I could be the comp. who grows old with you 
I wanna grow old with you...



(with the tune of 'Grow old with you' by Adam Sandler)

"I want to grow old with you! Speak to me, my computer! Yes, I want to grow old with you!", the Computer Addict said.



Not only people, animals and plants are getting older. Even computers grow old also like us. Computer, is getting old as time passes. As the time passes, the better the computer. 
Your computer now is in it's fifth generation, meaning to say, there are 5 generations of computer. 

Generations of Computers

First Generation (1940-1956) Vacuum Tubes


The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

Second Generation (1956-1963) Transistors


Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

Third Generation (1964-1971) Integrated Circuits


The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

Fourth Generation (1971-Present) Microprocessors


The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip.

Fifth Generation (Present and Beyond) Artificial Intelligence


Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality.
