Notes - Computer and Electronics

Computer & Electronic COMPUTER History · The earliest known tool for computation was the Abacus. It was developed in China. · Blaise Pascal invented the second real mechanical calculator called Pascaline. · Charles Babbage is considered as the 'father of computer' because he invented difference engine in 1822 and then analytical engine, which can store the information on punch cards, in 1837. · Alan Turing is regarded as father of 'modem computer' science. Characteristics of Computer The characteristics of a computer are as follows: · Speed: The computer uses the electronic pulses, the speed of those pulses is virtually instantaneous and process the inputs in microseconds, nanoseconds or piccosenconds. ·Biotechnology and Genetics · Biotechnology, generally speaking, is any technique that is used to make or modify the products of living organisms in order to improve plants or animal or to develop useful microorganisms. · In modem terms, biotechnology has come to mean the use of cell and tissue culture, cell fusion, molecular biology, and in particular, recombinant deoxyribonucleic acid (DNA) technology to generate unique organisms with new trait or organisms that have the potential to produce specific products. · The origin of biotechnology can be traced back to prehistoric times, when microorganisms were already used for processes like fermentation. Although a molecular biologist may consider cloning of DNA to be the most important event in the history of biotechnology, the latter has actually been rediscovered more...
