        Evolution of computer-:  Blaise Pascal invented the first mechanical adding  machine in 1642 Baron Gottfried Wilhelm von Leibniz invented the first calculator for multiplication in 1671. Keyboard machines originated in the United States around 1880.  Around 1880, Herman Hollerith came up with the concept of punch cards that were extensively used as input media until the late 1970s. Charles Babbage is considered to be the father of the modern digital computer. He designed “ Different Engine ” in 1822 His efforts established a number of principles that are fundamental to the design of any digital computer.                Some Well Known Early Computers  The Mark I Computer(1937-44)  The Atanasoff-Berry Computer(1939-42)  The ENIAC(1943-46)  The EDSAC (1947-49)  The EDVAC (1947-52)   Manchester Mark I (1948)   The UNIV...

Fifty generations of computer-:  In fifth generation very powerful and compact computers become available at a cheaper rate. The concept of artificial intelligence were used in this generation. Several new types of exciting applications like E-comers, Virtual library, artificial intelligence, multimedia, etc. emerged during the period. The characteristic features of fifth-generation computers are as follow: Firth generation of computer | features and characteristic of 5th generation of  computers learn first generation of computer Learn second generation of computer Learn third generation of computers Learn forth generation of computers (i) Use of parallel processing-: In this generation new integrated circuits SLSI/ULSI(super/ultra large scale integrated circuits) were used. That is also called parallel processing. (ii) Use of artificial intelligence-: The computer of this generation has used the concept of artificial intelligence. These computers ...

Fourth generation of computer -:   With large scale integrated(LSI) semiconductor circuits called microprocessor getting, developed, there was a revolution in computer technology. With microprocessor, microcomputer was developed. Forth generation of computer| Features and characteristic of forth generation computers learn first generation of computer Learn second generation of computer Learn third generation of computers Learn the fifth generation of computers The following are the technical features of computers of these generations: (i)Development of microprocessor-:   With the development of VLSI now it is possible to design the entire CPU In a single chip of size less than one inch, which is called the microprocessor . (ii) Input /Output media-:   With the use of keyboard, monitor. printer new input/output media were developed that include direct input devices, optical scanning, audio responses, etc. (iii) Semiconductor internal memory...

Third generation of computer Third generation of computerm | characteristic and features of third generation of computers learn first generation of computer Learn second generation of computer Learn forth generation of computers Learn fifth generation of computers Third generation of computer(1965-1974)-: Third generation of computers witnessed major advantages and changes I  hardware and software capacities. The major technological features of computer s of this generation are-: (i) Use of integrated circuits-: Transistors were replaced by integrated circuits. IC’s decreased the size, cost and power consumption to a great extent. (ii) Input/ Output media-: For input and output operation monitors and keyboards were introduced. (iii) Use of magnetic disk-: For secondary storage magnetic disk was used which was larger in capacity and faster. For internal memory, a magnetic core was used. (iv) Use of operating system-: Sophisticated operating system...

Hello friends, today we learn about  the second generation of computers,   features of second-generation computers  and the  advantages  and  disadvantages of second-generation computers  in it, so let's start. second generation of computer | Advantage and Disadvantages of second generation computers INTRODUCTION-: The second generation of computer-:  with the invention of the  transistor  by bell laboratories the  vacuum tubes  are the first generation was replaced by the transistor. The major advantage of the use of a  transistor  was that the size of the computer has come down as well as  power consumption. The following technical features of these computers of  second generation-: (i) Use of transistor-:   Transistors  were used in the circuits in place of vacuum tubes. (ii) Punch card as input/output unit-:  The input operations were performed using punched cards...

Hello friends, today we learn about the First generation of computers, features of first-generation computers ,and  advantages and disadvantages of first-generation computers in it, so let's start. INTRODUCTION - :       The First-generation of computer-: The period of the first generation was from 1940 to 1956. The first-generation computers relied upon the machine language, to owest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. The first generation computer uses a vacuum tube as the basic component because the vacuum tube is the only electronic component available on those days. The vacuum tube is used for circuitry and magnetic drums are used for memory.  First generation of computer | Advantages and Disadvantages of first-generation computers   The general technical features of the first-generation computer are -: (i)Use of vacuum...
