Computers
This essay will explore the history of computers, show its importance and analyse theories of future computers and their use.

Computers definition
A computer defines as a device that accepts information and manipulates it for results based on instructions. The instructions are saved in the device as so called "Programs" and creating instructions is therefore called "Programming".
There are usually two kinds of computers. Either a computer with only one program built into it or a customizable computer that can run different programs and also be available for programming new programs.
These two types of computers can be found all over the society, in cars, households, stores, infrastructure etc.

History
The first computer device was created by a mechanical engineer and polymath named Charles Babbage. He is considered as ”father of the computer” since invented the first mechanical computer that eventually led to more complex designs. In 1833 Charles had just finished his revolutionary difference engine, a mechanical calculator. Upon completion he realized that a much more general design, a Analytical Engine, was possible. The input of programs and data was gonna be provided to the machine with punched cards. For output the machine would have a printer, a curve plotter and a bell. The machine would also be able to punch numbers onto cards to be read in later.
The machine was too early for its time. All thousands parts for the machine was made by hand. That was a major problem. Eventually the project was dissolved with the decision of the British Government to cease funding.
But then his son, Henry Babbage, completed a simplified version of the Analytical Engine in 1888. He gave a successful demostration of its ...

... to imagine. Problem with that theory is that transistors generate heat, and a hot processor can cause a computer to shut down. So the more transistors the hotter computers. Computers with fast processors need efficient cooling systems to avoid oerheating.

So to summarize. In the future computers will probably not be built with the current transistor build. Since the transistor is creating too much heat. There will be a new sort of computer, question is, how close are we?

The History of Computers in Education Essay examples - The history of computers in education starts with the MARK1 and ENIAC computers being used in 1944 and 1946 in Harvard and the University of Pennsylvania respectively. The first use of computers then in education was to compute problems in the mathematical, scientific, and engineering fields to allow students to deal with big problems they would more than likely encounter one day in a real world situation. In 1959, Donald Bitier began the “large-scale” PLATO project, which was a “several thousand-terminal system [that] served undergraduate education, as well as elementary school reading, a community college in Urbana, and several campuses in Chicago.” (Molnar) In 1963 at Dartmouth, John Kem...   [tags: HIstory of Computers, Education, Advancements]

Essay on History of Modern Computers - 1945-Present The evolution of modern computers is divided into a few "distinct" generations. Each generation is characterized by extreme improvements over the prior era in the technology used in the manufacturing process, the internal layout of computer systems, and programming languages. There has also been a steady improvement in algorithms, including algorithms used in computational science, though not usually associated with computer generations. The following timeline has been organized using a logical breakdown of events and discoveries....   [tags: PC computers Technology History Essays]

The History of Computers Essay - The History of Computers The idea of a machine that would make man’s calculations easier, faster, and more accurate is no new notion.

The History of Computers Essay - The History of Computers In order to fully understand the history of computers and computers in general, it is important to understand what it is exactly that lead up to the invention of the computer. After all, there was a time when the use of laptops, P.C.s, and other machines was unthinkable. Way back in the fourth century B.C., the abucus was an instrument used for counting in Babylonia. Many scholars believe that it likely started out as pebbles being moved over lines drawn in the dirt and then evolved into a more complex counting tool (Aspray 7)....   [tags: Technology Computers Essays]

History of Computers Essay - History of Computers It all began on a brisk, damp October evening in the year nineteen hundred and ninety-nine. All was silent in the household except for the incessant whistling of the tea kettle on the kitchen stove. Oh, and how can I forget the humming of the lawnmower in the backyard. I had just arrived home from band practice when the doorbell rang. Anxious to see if it was for me, I raced down the stairs in hopes that I had received a package, or perhaps flowers, from a boy....   [tags: Computers Technology Technological Essays]
