Computer Ancestors -Blaise Pascal built the Pascaline in 1642, which was the first mechanical calculator ever made. -Early mechanical calculators could only add and subtract.
Computer Ancestors Continued... -A difference engine is an automaticmechanical calculator designed to tabulate polynomial functions
Early Electronic Computers -Colossus was the world's first electronic,digital, fixed-program, single-purpose computer with variable coefficients -ENIAC stands for Electrical Numerical Integrator and Calculator -The ENIAC was developed in the army, because they needed a computer for calculating artillery firing tables
First Hobby/Home Computers -The Altair computer appealed to individuals and businesses that just wanted a computer -Colleges had required science and engineering majors to take a course in computer programming, typically using the basic languages. -First computer cost around $439.00. It included everything in kit. The MITS designers wanted the computer to appeal more to hobbyists -The Alto Computer was the first networked personal computer
Two Guys in a Garage -Apple computer was started in 1976 with the creation of the Apple 1. -In 1977 Apple continued with the Apple 2 it had color graphics and its electronics inside a plastic case -In 1983 Apple did it again with the Macintosh that added an icon interface navigationed by a computer mouse and has served as a model for computers
COMPUTERS TODAY -A computer is used for researching, documents, and other helpful uses. -Including concepts like: education, health, medicine, science, business, recreation, entertainment, government, defence,sports, etc. -Popular programs include: Microsoft Word, Microsoft PowerPoint, Microsoft Excel, and Microsoft Access
