Unlike Jacquard's silk loom, which required workers to manually insert a single punch card at a time, Babbage's Analytical Engine used a series of punch cards.He invented the Analytical Engine, a machine that could solve complex math problems using punch cards adapted from Jacquard's silk loom.In the 1830s, an English mathematician and scientist named Charles Babbage built upon Jacquard's work.By the time of Jacquard's death in 1834, there were more than 30,000 looms using punch cards. In the end, the invention was too useful to be ignored.But a group of silk weavers feared the computing device would put them out of work, so they destroyed one of Jacquard's first looms.The invention impressed French leaders, including Napoleon.Jacquard's invention greatly improved output and reduced human error in the production process. The cards controlled the patterns the loom followed, which ultimately created different types of cloths and designs.When placed into a silk loom, a type of cloth-making device, the punch cards created a type of primitive computer program.Recognizing this trend, French inventor Joseph-Marie Jacquard developed a system of punch cards to increase productivity in textile factories.The more technologically advanced a factory was, the more goods it could manufacture and sell for profit.As industry spread across the continent, people started leaving their farms to work in factories where goods were produced.European life began to change in the early 1800s.As a result, complex mechanical computers were rare and mostly used by scientists. However, communities in the 1600s were still largely agrarian and had little use for mechanical computers.About 20 years later, French mathematician Blaise Pascal invented a similar device.Schickard's computer used gears to add and subtract numbers. One of these was created by German scientist Wilhelm Schickard.Several complex mechanical computers were also developed in the 1600s.The slide rule was gradually replaced by handheld calculators.

Because of its usefulness and convenient size, most high school and college math students carried a slide rule with them to class up through the mid 1970s.

It is commonly used to solve multiplication and division problems.

Developed in the 1600s, the slide rule is a mechanical computer on a stick.

The slide rule is another early computing device.

The hundreds has a 'five' bead alone, so that is 500. The tens column has one 'five' bead and two 'one beads, representing 70. The units column has a single 'one' bead and no 'five' beads, so this is one. The top two beads represent five each, and the bottom beads represent one. The zero position is for all beads to be away from the central bar, as the beads on the left are.

People can solve addition and subtraction problems by sliding beads back and forth on a string.

With these basic machines, which are still in use today, beads represent numbers.

The earliest and simplest mechanical computer is known as the abacus.

Mechanical computers rely on parts that must be physically moved in order to perform a task.

Because early computers did not use electricity, they are referred to as mechanical computers.

In fact, if you were to see one of these devices today, you would probably not realize you were looking at a computer.

They had no keyboard, mouse, or monitor.

The earliest computer devices were much different than the ones we use today.

By the end of the lesson, you will understand how computing technology evolved into its present form.

It also explains the major historical breakthroughs in computing technology.

This lesson introduces you to some of the first forms of computers.

Since then, our understanding of computers has changed and focused on machines.ДЄs computer technology has evolved, computers have become an indisputable part of our daily lives.

At that time, computing was thought of as an occupation.

Before the electronic computers of today, we relied on individuals who used mathematics to solve equations.

I can analyze the impacts of technology on history and society.Дid you know that the earliest computers were not machines?.

I can outline historical developments in computer technology and identify key figures in the history of computers.

I can use and understand basic computer terminology.

Unit 1: History of the Computer This lesson summarizes the historical development of computing devices over the past several hundred years.
