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 automatic mechanical calculator designed to tabulate polynomial functions

-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

Early Electronic 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

First Hobby/Home Computers

-Apple computer was started in 1976with 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 iconinterface navigationed by a computer mouse

and has served as a model for computers

Two Guys in a Garage

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
