Answers
Answer:
1) The characteristics of computers that have made them so powerful and universally useful are speed, accuracy, diligence, versatility and storage capacity. Let us discuss them briefly. Computers work at an incredible speed. A powerful computer is capable of performing about 3-4 million simple instructions per second.
2) Analytical Engine, generally considered the first computer, designed and partly built by the English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871). ... There is no evidence that anyone before Babbage had ever conceived of such a device, let alone attempted to build one.
3) vacuum tubes
The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.
4) Alan Turing
The father of modern computer science. 1912 - 1954.
5) FEATURES OF SECOND GENERATION COMPUTERS
Transistors – small, low-power, low-cost, more reliable than vacuum tubes.
Magnetic core memory.
Two's complement, floating point arithmetic.
Reduced the computational time from milliseconds to microseconds.
High level languages.
6) Limitations of first-generation computers:
The major limitations of first generation computers.
The operating speed was very low.
Power consumption was very high.
They required large space for installation.
The Programming capability was quite low.
Quit larger, they generate lot of heat require special housing.
