    First abacus

    First abacus
    There is the belief that the abacus originated in Central Asia, but it is difficult to know its exact origin since it was invented thousands of years ago. The abacus is used to perform arithmetic calculations in an easy and understandable way. In almost all the abacuses there are lines of ten units.

  • First Calculator

    First Calculator
    It was invented by Blaise Pascal invention the first calculator, It was a box with discs that marked units. This calculator had many bugs, so it was not accurate but revolutionized mathematics. Today calculators are accurate but this invention was what started everything.

  • Processor

    Processor
    The first processor was mechanical and it was invented by Henry Mill. Processors are the hardware device of a computer that can be the central processing unit or the brain of the system. Processors are formed from kernels, cache, memory controllers, graphics cards, and other elements. https://www.youtube.com/watch?v=YwCYiometEk

  • Perforated cards

    Perforated cards
    Es un instrumento pequeño capaz de almacenar y/o procesar información; Se programan según las necesidades. Esta invención dio paso a la creación de computadoras más pequeñas. Que las computadoras eran más pequeñas para todo más fácil, la batería no tenía que ser tan grande, era fácil de transportar y no pesaba.

  • Battery

    Battery
    The battery is a way to have saved energy, that works at your disposal. It was invented by Alessandro Volta an Italian physicist, initially began studying how to manage to pass the electric current between two metals, and then transmit that electricity to other elements. https://www.youtube.com/watch?v=rHlc6cCqCy8

  • First Computer

    First Computer
    The first mechanical computer created it Charles Babbage, was not programmable and was calculations and copies on paper. This computer was only gigantic, weighed about 30 tons and had only one purpose, so at first it was not so useful, but it has evolved so much that nowadays it is used almost for everything.

  • Binary Code

    Binary Code
    Gottfried Wilhelm Leibniz implemented the binary system algebraic equations, establishing the basics of what would be the logic of computers. So basically it's a system of 0 and 1 that represents texts or instructions from a computer. https://www.youtube.com/watch?v=ADhDDo3tTFk

  • Maagnetic tapes

    Maagnetic tapes
    It is a very cheap type of storage that can store many data that are recorded on a plastic tape with magnetized material, was created by the English inventor, Oberlin Smith. They are made of iron oxide. The sounds or images within these tapes can be played back.

  • Enigma Machine

    Enigma Machine
    This machine had a rotary encryption mechanism, which allowed use both to encrypt and decrypt messages. Several of its models were widely used in Europe

  • The First Programable Computer

    The First Programable Computer
    Konrad Zuse invented the Z1, the first programmable computer that was used only for military purposes. These computers were called D second generation and are more like what we now know. They were pretty rudimentary but eventually they were getting better.

  • Programing Languages

    Programing Languages
    They were made to communicate instructions to a computer is a programming language that can be used to create programs that are then coupled to a Web page, this makes it much more easy for humans, because so you can send the Instructions to the computer

  • First Operative System

    First Operative System
    The first operating system in history was created for an IBM 704 computer, and basically all it did was start running a program when the previous one finished. https://www.fib.upc.edu/retro-informatica/historia/so.html

  • Integral circuits

    Integral circuits
    The first integrated circuit was developed by engineer Jack St. Clair is a very thin tablet or chip in which you will find a huge amount of microelectronic devices interacting

  • First Microchip

    First Microchip
    It is a small instrument capable of storing and/or processing information; They are programmed according to the needs. This invention gave way to the creation of smaller computers. That computers were smaller to everything easier, the battery did not have to be so big, it was easy to transport and did not weigh.

  • The Mouse

    The Mouse
    Fue inventado por Douglas Engelbart para poder hacer un movimiento simultáneo en la mano y en la computadora. Este invento permitió que fuera mas fácil de hacer movimientos en la computadora. Los primeros utilizaban una bolita en la parte de abajo para replicar los movimientos.

  • First Tablet

    First Tablet
    It was invented by Alan Kay and was baptized as Dynabook, a computer weighing less than 2 kilos and a graphical display. It was designed for children, was able to show at least 4000 characters with print quality. To this day tablets are used for many things, such as drawing tablets. Easy for humans, as this way you can send the instructions to the computer

  • RAM memory

    RAM memory
    It was invented by the American Robert Dennard, they are memory modules that are used in personal devices and servers. It consists of welded integrated circuits on a printed circuit. This memory improved much the design of the computers.

  • Creeper Virus

    Creeper Virus
    It was the first computer virus to exist. It was an accident and it was actually supposed to be able to see if you could create a program that moved between computers. Bob Thomas invention His main objective was the DEC PDP-10 computers with the TENEX operating system.

  • First Software

    First Software
    They were called floppy discs and they were developed by IBM, this software was quite rudimentary but it gave rise to many more advances

  • Motherboard

    Motherboard
    It was invented by IBM and hosted the CPU and RAM of the computer, provided audio as well as many other functions, provided ports for the keyboard and tape cassette and had expansion slots for additional cards. This invention allows the order of the electronic circuits, the processor, the memories, and the main connections, in it all the components of the computer are connected.

  • First Laptop

    The first laptop computer available to the public was the Osborne 1. The Osborne Computer Corporation released this model in 1981. It cost $1795 at the time of release. The screen was five inches long and the keyboard was in the lid of the computer. (The screen of the Eee netbook pictured here is not much bigger!) It did not have a battery and was quite heavy.

  • First Social Media

    First Social Media
    The first social network called classmates was born as a website to help people meet their former classmates and work. This social network was not very famous but its designs inspired creators and soon the social networks became famous.

  • First Smartphone

    First Smartphone
    It was invented by Ericsson, he described his model Ericsson GS88 Penelope com A smartphone: Smartphones were not invented simultaneously with the internet, without or which were invented before. These phones have had many improvements and today are the phones most used by people.

  • USB

    USB
    Fue inventado por Amir Ban, Dov Moran y Oron Ogdan, esta memoria sirve para poder guardar información por un medio externo de la computadora. Esto invento sirvió mucho porque no necesitas utilizar el almacenamiento de la computadora para poder guardar coas, ademas su diseño es pequeño así que es bastante fácil de transportarlo.
