Features of 1st to 5th computer generation?

Answer 1

First generation (1940-1956) Vaccum Tubes

Second Generation(1956-1963)Transistors

Third Generation(1964-1971)Integrated circuits

Fourth Generation(1971-present)Microprocessors

Fifth Generation (present-future) Artificial Intelligence

Answer 2

• Vacuum tubes
• Many kinds of different main memories: delay line, magnetic drum, electrostatic CRT, magnetic core, etc.
• Small expensive main memory (equivalent of 1 byte cost $10 to $100)
• Punched card or magnetic tape I/O
• Different types of computer for scientific and business uses

Answer 3

• Vacuum tubes
• Usually magnetic tape I/O (punched cards generally processed off-line, translated to/from tape images, to reduce wasted CPU time waiting for slow card transports)
• Variety of different main memories: Mercury delay lines, Magnetic drums, Williams Tube CRT memory, Magnetostrictive delay lines, Selectron tubes, Magnetic core memory, etc.
• Poor reliability
• On site engineer(s) from manufacturer to repair failures
• Software either run one job at a time or in batches
• No operating systems

Some first generation computers were still running at customer sites into the middle 1970s, long after vendor had dropped support, because of the difficulty of porting software to newer computers with different architectures.

Answer 4

First generation computers don't have characteristics.

The primary characteristic of first generation computers, by most definitions, is that they were built with vacuum tubes.

"they don't have characteristics"?? Really?

Everything has characteristics.

They were slow , large, ran with vacuum tubes , they generated a lot of heat and weren't all the efficient.

Answer 5

"17,468 vacuum tubes, 7,200 crystal diodes, 1,500 relays, 70,000 resistors, 10,000 capacitors and around 5 million hand-soldered joints ... weighed 30 short tons (27 t), was roughly 8.5 by 3 by 80 feet (2.6 m × 0.9 m × 26 m), took up 680 square feet (63 m2), and consumed 150 kW of power" (From Wikipedia, the free encyclopedia)
