History Of ComputersBy: Mark Muscara,Cassie Trosino, Bridget Thompson,and Haley Winslade 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.

haley will be saying thisComputer Ancestors Continued...-A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions

haley will be saying this one-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-Apple computer was started in 1976 by steve jobs steve wasneack with the creation of the Apple 1.that was created in the jobs faimley gradge And then In 1977 Apple continued with the Apple 2 it had color graphics and its electronics inside a plastic caseAnd In 1983 Apple did it again with the Macintosh that added an iconinterface navigational by computer mouse and has served as a model for computers cince 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 AccessWorks Cited"Computer Catalog."
