I will present a brief history of the computer since it is prominent in society. 

The twentieth century was a time of invention and innovation. More specifically, there were major advances in computer technology as electricity developed. The invention of the computer originated from the reliance on electrical based machines that stemmed from a dependence upon mechanical devices. The stepping stones for computers originated in the early 1900’s, but computer advancement occurred most prominently from the 1930’s to the 1950’s. In the late 1930’s, using Alan Turing’s Information Theory, the first computer was built. Yet, as more applications of new scientific knowledge were needed to solve problems in the military and scientific communities, computer research increased. Engineers, scientists, and mathematicians were major influences upon the technological industry and its development of computers. These early computers needed teams of specialists in order for the devices to even function. MIT, Harvard, and University of Pennsylvania put together teams of these experts, and although expensive, the United States’ government funded the majority of the support throughout the 30’s, 40’s and 50’s. These specialists adapted new technologies applying scientific knowledge to gradually modify and enhance these machines (Cortada 15). It was challenging for the specialists, since “nothing was inevitable; the computer was not a historical phenomenon waiting to happen (14). 

As time progressed, new materials and advanced ways to package components were introduced in order to lower manufacturing costs. In the 1950’s and 1960’s, the older machines were replaced by new ones with a greater function per unit cost (Cortada 12). It was in 1960 and 1961...

...s for desktop computers, Apple introduced its first computer in 1977. It sold for $1,195 and had 16K of Ram. At the time, this was the fastest growing company in American history at the time (Augarten 280). Presently, this computer can be sold at auction for nearly $25,000 (“Old and Gold”). After the introduction of Apple’s computer, IBM presented its PC in 1981; it became the most popular ordinary commodity at the time (Augarten 280). 

Financially, computers could have been small and inexpensive from the start if Atanasoff published his electrical calculating machine, but instead, the computer originated from the large and costly ENIAC. The computer has made incredible advancements in society for all ages and professions, and early pioneers would have laughed at the thought of computers being used for these purposes, as their work started from room-sized machines.

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]

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]
