Essay on use of computers

Computers Timeline The 20th century was nearly into its fourth decade before the first electronic computer came along, and those early machines were behemoths capable of only the most basic tasks. Today, tiny "handhelds" are used for word processing and storage, delivery of documents and images, inventory management, and remote access by workers to central offices. Programmable electronic devices of all sorts have come to pervade modern society to such a degree that future generations may well designate the 20th century as the Computer Age.

Concept creation[ edit ] The article was a reworked and expanded version of Bush's essay "Mechanization and the Record" Here, he described a machine that would combine lower level technologies to achieve a higher level of organized knowledge like human memory processes.

Shortly after the publication of this essay, Bush coined the term " memex " in a letter written to the editor of Fortune magazine. As described, Bush's memex was based on what was thought, at the time, to be advanced technology of the future: The memex, in essence, reflects a library of collective knowledge stored in a piece of machinery described in his essay as "a piece of furniture".

Coincidentally, the same issue of Life contained aerial photos of Hiroshima after the dropping of the atomic bomb, a project Bush was instrumental in starting. Bush also discussed other technologies such as dry photography and microphotography where he elaborates on the potentialities of their future use.

For example, Bush states in his essay that: The combination of optical projection and photographic reduction is already producing some results in microfilm for scholarly purposes, and the potentialities are highly suggestive.

He believed people would create links between related articles, thus mapping the thought process and path of each user and saving it for others to experience. Wikipedia is one example of how this vision has in part been realized, allowing elements of an article to reference other related topics.

A user's browser history maps the trails of possible paths of interaction, although this is typically available only to the user that created it. Bush's article also laid the foundation for new media.

Doug Engelbart came across the essay shortly after its publication, and keeping the memex in mind, he began work that would eventually result in the invention of the mousethe word processorthe hyperlink and concepts of new media for which these groundbreaking inventions were merely enabling technologies.

A library of a million volumes could be compressed into one end of a desk.

When data of any sort are placed in storage, they are filed alphabetically or numerically, and information is found when it is by tracing it down from subclass to subclass.

It can be in only one place, unless duplicates are used.

Outlook in the use of science[ edit ] Bush urges that scientists should turn to the massive task of creating more efficient accessibility to our fluctuating store of knowledge. For years inventions have extended people's physical powers rather than the powers of their mind.

He argues that the instruments are at hand which, if properly developed, will give society access to and command over the inherited knowledge of the ages. The perfection of these pacific instruments, he suggests, should be the first objective of our scientists.

We should be able to pass the tedious work of numbers to machines and work on the intricate theory which puts them best to use. If humanity were able to obtain the "privilege of forgetting the manifold things he does not need to have immediately at hand, with some assurance that he can find them again if proven important" only then "will mathematics be practically effective in bringing the growing knowledge of atomistic to the useful solution of the advanced problems of chemistry, metallurgy, and biology".

The inventory needs to be revised, the salesman needs to be given credit for the sale, the general accounts need an entry, and most important, the customer needs to be charged.

Indeed, as of today, "science has provided the swiftest communication between individuals; it has provided a record of ideas and has enabled man to manipulate and to make extracts from that record so that knowledge evolves and endures throughout the life of a race rather than of an individual".

Another significant role of practicality in technology is the method of association and selection.

Bush concludes his essay by stating that: The applications of science have built man a well-supplied house, and are teaching him to live healthily therein. They have enabled him to throw masses of people against one another with cruel weapons.

They may yet allow him truly to encompass the great record and to grow in the wisdom of race experience. He may perish in conflict before he learns to wield that record for his true good. Yet, in the application of science to the needs and desires of man, it would seem to be a singularly unfortunate stage at which to terminate the process, or to lose hope as to the outcome.

Now, after the war, they need new duties. The use of Science has improved tremendously in many ways for humans. The knowledge of science has grown considerably. However, the way we manage it still remains the same for centuries. We are no longer able to use what Science finds out.

Alternatively, the technology has matured greatly and allows us to now produce complicated, yet cheap and dependable machines. Science is really useful. However, in order to have it to be very efficient and useful it should not only be stored but also be frequently consulted and enhanced.

In the future we would probably be able to store human writings in a small room with the use of photography. Using the latest advances of speech recording and stenographywe will soon be able to make printing immediate.

The advancement of photography is not going to stop. The thought process of repetition could be in relation to machine. Electrical machines will be the advancement of arithmetical computation.Computer Technology Essay Sample. By Lauren Bradshaw. April 22, Sample Essays.
