Digital computers do not need to be electronic, but have sometimes been implemented mechanically, hydraulically or pneumatically. To be fast, computers have to be electronic and the first devices used were valves (tubes). These are relatively large, and consume around 10 watts of power each, and since thousands were needed, computers were large and needed a lot of power. Transistors were next, once they became fast enough, and computers became much smaller. The next step was the integrated circuit ("chip") which comprises hundreds, thousands, or millions of interconnected transistors made in one (small) piece. These have continued to become smaller and more complex year by year.

What are the Conclusion of five generations of computers?
First Generation (1940-1956) Everything started with vacuum tubes. These were widely used in the first computer systems for circuitry, while magnetic drums were used for memory. Second Generation (1956-1963) Next, there was the introduction of transistors, which came in to replace vacuum tubes. ... Third Generation (1964-1971) Third-generation computers were where we saw the introduction of integrated circuits (IC), which are still in use today. Fourth Generation (1971-2010) In the fourth generation of computers, the invention of the microprocessor (commonly known as CPU) helped to get computers to the desk and, later, lap-size that we ... Fifth Generation (Present Day) Although we are still using technology from the fourth generation of information technology, we are now going into a new age: the fifth generation.
1st generation of computer?
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.
When computers first came out did they do a lot?
The early first generation computers could do most of the things modern computers can do, and a few things modern computers can't. Their main limitations were very small memories (modern computers with gigabytes of RAM and terabytes of disk appear to have unlimited resources compared to the early machines) and slow speeds due to the large logic signal swings of vacuum tubes (sometimes up to 200V between low and high).
What is the difference between first generation and second generation computers?
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.
What are computers that are very large and very expensive?
Supercomputers
Write the key points of first generation computers?
First Generation computers were made out Vaccum Tubes. They required alot of Electricity and emitted a lot of heat. Vaccum Tubes were also needed to be replaced when it becomes really hot. So Vaccum Tubes were not very efficient or easy to handle.
What is the differns about the first and second generation ipod touch?
There is a very large difference.First generation has a square Wi-Fi antenna, the second has an oval one.The processor and RAM of the second generation are significantly faster than that of the first generation.The second generation is thinner than the first generation.The second generation can handle most Wi-Fi multiplayer games that the first generation cannot.Basically, the second generation is a very large step-up in everything from the first generation.
What years was the first generation of computers?
1940-1956 ENIAC was produce by john preper eckert and john W. Marchley in the university of pennislevaya and US government It comsist of 18000 vaccume tubes and 7000 resistor The mechanial language was one and only language used of operating this machine In first generation of computer vaccume tubes and magnatic drums were used out standins features for first generation of computer 1 quite large 2 slow speed 3 very expensive 4 generated lot of heat 5 less storage capacity 6 special housing
Why were the ABC and ENIAC considered first generation computers?
They are first generation computers because they used vacuum tubes as active elements, as did almost all computers until 1958 when the first generation is usually considered to have ended. From 1958 on most computers used discrete transistors as active elements until 1964.Note: ABC & ENIAC are both very early first generation computers as they used ordinary Radio receiver vacuum tubes, not the more expensive Computervacuum tubes that were introduced about 1948 to 1949. The later Computer vacuum tubes were custom redesigned versions and were far more reliable than ordinary Radio vacuum tubes had been.
What are the advantages of third generation computers?
the computer of this generation could be developed after the development of integrated Circuits. integrated circuits were made of cilicon.A single IC could hold a no.of transistors and resistors.this was also called chip. the computer of this generation were 1000 times fast as compared to first generation computers and their cost was comparatively low.The memory of these computers was much more and data processing became very fast.
Characteristics of fifth generation of computers?
Fifth generation computer is also known as a. Knowledge information processing system b. Very large scale integration (VLSI) c. Both of above d. None of above
What do you call the 4 generation of the computer?
Computers of era fall between year 1972-1984,development of large scale integration LSI(1000devices per chip)& very large scale integration VLSI(10000DEVICES PER CHIPS)
