First Generation Computers refer to ones with vacuum tubes and were really huge and required vast amounts of electricity. The programming was very limited and very complex USN machine language. Usually they were hardwired and the applications very limited.
Second Generation Computer were built using transistors that were much smaller and required less power and space. General Purpose program languages were developed that could be moved from 1 computer to the next.
Transistor were used in second generation computers. They produced low heat, reliable than vaccum tubes. In third generation computers Integrated circuits were used and keyboard were introduced.
In most systems of classifying computers into generations, first generation computers used vacuum tubes while second generation computers used discrete transistors. Some differences:
The first generation of computers back in 1940 were vacuum tubes. There were vacuum tubes for circuitry and magnetic drums for memory. There huge in size, consumed lot of electricity and generated lot of heat. There were expensive to operate and heat was the main cause of failure.
The current generation or the fifth generation of PCs are based on microprocessors and thousands of integrated circuits drawn on a single silicon chip. They are affordable, extremely energy efficient and are small in sizes as small as it could fit in the palm of the hand.
transistors vs. integrated circuits
it varied significantly from computer to computer within each generation with large overlaps from generation to generation but the running trend has been for greater storage capacity in each successive generation.
Electro-Mechanical Computers were used before first generation of computers.
First Generation- 1945-1956-Atansoff berry Computer. Second Generation-1956-1963-Transistors. Third Generation-1964-1971-Integrated circuits. Fourth Generation-1971-Present-Apple Macintosh.
No difference really, they still take 1's and 0's and make mathematical calculations corresponding to their instruction sets (CPU). What is DONE with that has changed dramatically tho, with every new generation, and that's about the only real difference...well besides the darn size thing. Any more of an answer would be doing your test for you, and take far more room than this page offers. 1st generation computers used vacuum tubes. This generation spanned roughly 1940s to 1958. Today's generation uses very complicated integrated circuits. It started no earlier than the 1990s. A typical single IC from a modern computer contains several orders of magnitude more components than an entire 1st generation computer occupying an entire room, and runs at speeds unimaginable in the 1st generation.
First generation computers were built with vacuum tubes. The capabilities were about the same as that of modern computers, except limited by very small memories and slow speed. Typical first generation computer memory cost from $2 to $20 per byte equivalent, whereas today's computer memory costs less than a micro-penny per byte.
The difference between the 1st and 3rd generation iPod is slightly different. the cases will still work, the difference between the two generations is that the 3rd generation is slightly slimmer than the 1st generation.
Well, the 2nd generation version is thinner, and that's about it!
This is hard to answer, because there is no industry standard for what a 'generation' is. It is entirely subjective. You will need to define a 'generation' before a comparison is given. IE, there are 3 generations of AMD Phenom II processor, and over 70 generations of AMD processors. There are five major generations in processor bitrate. There are over 400 generations of individual progressments in major computer technology. There are nearly 50 different generations of individual architecture design.
A lot slowerBack is differentDoes not support some appsNot as sexy
The exact date of 1st generation Computer is May,1941.
well the 2nd generation has built in speakers, youtube, access to email, and a bunch of other crap.
There are certain games that you cant get on the ipod 1st generation also you you cant update ipod 1st gen with the new softwares but with the 3rd gen you can carry on updating it.
Well, mainly its just an updated version and 1st generation doesn't have built-in speakers like the 2nd does.
the second generation is thinner and has better software
The 1st generation has a box shaped outershell while the 2nd generation has a more comfortable curved grip. The biggest difference is that the 2nd generation has external speakers that can be adjusted with the external volume control. The first generation does not. There are also minor changes like better graphics and a wider variety of apps.
it varied significantly from computer to computer within each generation with large overlaps from generation to generation but the running trend has been for greater storage capacity in each successive generation.
but they were. for the time they were built they were and did.
