Introduction

Hello my name is Tiffany Broughton my

colleague is Jaimmie Bajanen.

Necessity is the Mother of Invention

Our technology has evolved because we

have better computers that are easier to use

and more efficient.

Generation 1

This is when the first digital computer was built

It was started to be built in 1937 and finished in

1939 John Vincent Atanasoff, and Cliford Berry

At Iowa State University

This machine was not intended as general-purpose

computer, it was built to solve physics equationsthat Atanasoff was working on at the time

using electronic vacuum tubes, as the switchingcomponents

This invention of the transistor which was

faster, smaller and required considerably

less power to operate

This was introduced in 1959

Generation 2

Generation 3

By the late 1960s devices which included

more than one circuit on a single silicon

chip became available

Generation 4

In about 1970 the technology was available

to place an entire CPU on a single chip and

the micro processor was born.

Generation 5

Current trends now are to exploit the advantages

of computer systems which can contain literally

thousands of computers. This means that thousands of computations can be

taking place at the same time.

This type of large scale processing of information

makes it possible to explore very different kinds of

processing that could be done earlier.

Positives

One positive that the computer has is that it

makes it easier to find information and

faster to find it.

Another positive is that they are more

efficient, then they used to be.

Another positive is that it makes it easier totalk to friends on Aol or Yahoo.

Negatives

One negative is that they can be very slow

Another negative is that it might not find

the exact information you need, or it might

give you something you dont need.

Reflection

One important thing we learned was that

computers are a great way to find

information on many topics.

Our opinion is that we are glad that John

Atanasoff and his colleague designed the

computer. It was a great idea!
