  • Pascaline

    Pascaline
    It only performed addition and never worked.

  • Stepped Reckoner

    Stepped Reckoner
    The Stepped Reckener first add, subtract, multiply, divide & square roots it was ahead of it’s time.

  • Ada Byron

    Ada Byron
    Ada Byron was the first female programmer.

  • Analytical Engine

    Analytical Engine
    It followed programs on punched cards and was designed to make decisions based on programs. It never built but it was model for today.

  • John Von Neumann

    John Von Neumann
    John Von Neumann had the idea of stored program in CPU to control all functions.

  • ABC

    ABC
    ABC was the first electronic computer and used the binary number system of 1s and 0s that is still used today.

  • Mark 1

    Mark 1
    It used punch cards, but could not make decisions so it was still a calculator, but it was 51 feet in length and weighted 5 tons.

  • Bluetooth

    Bluetooth
    wireless technology used to allow mobile computer devices to communicate

  • Transistor

    Transistor
    Transistor was invented to make computers smaller and less expensive.

  • UNIVAC

    UNIVAC
    UNIVAC was used to store program concept correctly andwas the first computer language (C-10) with the first keyboard. It was sold to Census Bureau in 1951 and is still large and expensive.

  • Bill Gates

    Bill Gates
    Created a BASIC language interpreter (1975)
    Founded Microsoft (1977)
    Developed MS-DOS for PCs and Windows

  • MB (Megabyte)

    MB (Megabyte)
    approx. 1 million bytes

  • Machine Language

    Machine Language ( 0’s & 1’s ) was the only language that a computer understand.

  • Integrated Circuits

    Integrated Circuits
    It replaced the transistors, it was the fastest,and it could make millions of calculations per second.

  • Mainframe

    Mainframe
    Large & Expensive ($100,000-millions range)
    Large corporations, banks, governments & universities
    Usually has ‘dummy’ terminals
    Usually requires their own room
    IBM System 360 was one of first
    A smaller ‘minicomputer’ was also used on a smaller scale
    Eventually MICROcomputers became common

  • BASIC

    BASIC
    (Beginner’s All-Purpose Symbolic Instruction Code) uses an interpreter so code can be tested as it is written

  • Microprocessor

    Microprocessor
    Entire CPU on a chip
    Made Microcomputers (computer small enough to fit on a desktop) possible

  • Hardware and Software

    Hardware and Software
    Hardware – the physical/touchable ‘equipment’ on a computer (monitor, keyboard, memory CHIPS, etc.)
    Software – the programs running
    Operating System Software – programs that run automatically when turned on & controls the computer use (i.e. DOS/Windows)
    Applications Software – performs specific tasks (word processor, games, etc.) https://en.wikipedia.org/wiki/Software

  • Internet

    Internet
    world wide (very large) network

  • The Desktop PC

    The Desktop PC
    Be able to identify hardware of the PC (monitor, keyboard, mouse, disk drives, etc.)
    Input Devices (Takes information in) vs. Output Devices (Sends information out)
    CPU (Central Processing Unit) processes data and controls flow of data (heart) & directs all activities of the computer
    ALU (Arithmetic Logic Unit) within the CPU for arithmetic and logic/comparisons (brain)

  • Accessing the Internet

    Accessing the Internet
    Internet services (ISP) & online information services (i.e. AOL) offer access and information to and on the Internet
    Telecommunications – transmitting and receiving of data
    Kbps (KB per sec.) or Mbps (MB per sec.)
    Modems transfer 0s and 1s into tones
    WWW – most widely used Internet service
    Browsers (i.e. Internet Explorer) GUI for info
