    When was the computer invented?

    I am very keen to find information about “Computers” and when its invention??? I know it’s a very a silly question. But I want know who exact has the best information about computer. Today computer is a vital device in day –to-day life. Any suggestions would be appreciated. Thanks in advance.

    Computer is mainly a machine in which we can carry out calculations and programming . The first use of computers was mainly recorded in 1613 where a person carried out calculations and computations. The machine that carries out computations is called “Computer” it was as simple as that.

    Re: When was the computer invented?

    Computer is a machine in which the arithmetic and logical operations are carried out in sequence through programming. Computer consists of a memory through which arithmetic and logical operations are carried out and a control unit that changes the order or sequence of the operations to be performed. A processing unit executes series of instructions that make the instructions to read the data, manipulate it and then store data. It changes the sequence of the instruction to function. The first electronic Digital computers were developed in the mid-20th century between 1940 to1945. Initially the computers was the size of the entire room and it would consume the power as compared to many tonnes of computer used now.

    In 1642, the Renaissance invented a device called mechanical calculator. It had the ability to perform all arithmetic operations without the help on human brain. The mechanical calculator was thus the main reason for the development of computers.

    In 1803, Joseph Marie Jacquard introduced computers by launching series of punched paper cards in textile loom as a template which allows the loom to automatically weave complex patterns. Charles Babbage was the first to introduce the concept designing a fully programmable mechanical computer,it was called analytical engine.

    In 1941,The first program-controlled computer was introduced by Konrad Zuse, who built the Z3 computer,which was a electromechanical computing machine.The first programmable electronic computer was the ‘Colossus’, built in 1943 by Tommy Flowers.

    The Atanasoff–Berry Computer (ABC) was the first electronic digital computing device introduced in 1937, the machine was not made for programming, it was simply made to solve systems and queries regarding linear equations.

    Re: When was the computer invented?

    A computer is a device or an electronic machine that computes and performs very high speed logical operations which is programmable.The Abacus was invented by the Babylonians in way back about 2400 BCE. The Abacus consists of movable counters that can be manipulated to perform add and subtract. The abacus is still used today for basic arithmetic in many parts of the world. The mathematics after that got very complex and thus the machine invented after that has to match the complexity of the logical operations.

    The modern era has technologies like automated calculation and programs. But it was lacking earlier when it was invented because they did not had that application to perform this operations easily. Computer comes with monitor which has screen processed in it. The interface between the computer ‘s screen and the operator is called “user interface”.

    Modern computers are based on integrated circuits and are billions times more capable and fast than the early machines, and occupy a fraction of storage space comparing the earlier.
    Colossus was the world's first electronic, digital and programmable computer used for encrypting the German messages in English during world war-II by british codebreakers. They used vacuum tubes to perform the calculation.

    George Stibitz is called as a father of the modern digital computer. At Bell Labs in November 1937, George Stibitz invented and built a relay-based calculator, it was the first device first to use binary circuits to perform an arithmetic operation. Later models added greater sophistication including complex arithmetic and programming for operation.vacuum tubes were used throughout the 1950s for performing calculation.

    Re: When was the computer invented?

    The general computer has four vital components:

    • arithmetic logic unit (ALU)
    • control unit
    • memory
    • input and output devices(I/O)

    these parts are interconnected through buses and they are made up of wires.the control unit manages computer’s various components. Arithmetic logic unit (ALU) is capable of two classes of operations which arithmetic and logic to be performed.memory contains of cells into which numbers can be placed or read for storage. And through I/O computer can exchange information with outside part of it.

    Modern day computers can also multitask and multiprocess. Computers have been using network and internet for many times since the 1950s. The U.S. military's SAGE system first used this system on a large-scale, after that it led to a number of special-purpose commercial systems such as Sabre to invent. In the 1970s, computer engineers at research institutions in the United States started to link their computers altogether using telecommunications technology called ‘ARPANET’.
