Read this comprehensive essay on Computers !Today’s generation could never ever imagine in their wildest dreams about the world, ages before, when there were no computers or any other technologies. So much we have advanced that now every information is just a click away and is in your hands 24/7. All this advancement was possible only with the introduction of a small device called the “Computer”.Image Curtsey: csntrust.org.nz/attachments/Image/PC-picture-1.jpg?1367216528141Basically, computer is a device that accepts the message by the imputer and processes this message and stores the information at the storage devices and later gives an output of the message through the output devices.A simple explanation of the computer. Normally, a computer consists of a processing unit called the Central Processing Unit or the CPU and a form of memory. In the years between 1940 and 1945 were the first electronic digital computers developed. The initial sizes were as big as a room and consumed power as much as today’s personal computers.Initially, computer was related to a person who carries out calculations or computations and as such the word computer was evolved in 1613 and continued till the end of 19th century. Later it as re-described as a machine that carries computations.The early computers were limited in their functions. It was the fusion of automatic calculation and programmability that produced the first computers that were recognized in 1837. Charles Babbage in 1837 was the first to introduce and design a fully programmed mechanical computer, his analytical engine. Due to limited finances and inability of resisting tinkering with the design, he could not complete his work and it was later completed by his son Henry Babbage who made it into a simplified version of the analytical engine’s computing unit.The original objective of inventing a computer was to create a fast.
Computers make our lives completely different. Our current significant development is due to computers in many areas. Examples of these areas are business, medicine, environment, technology, education and also our daily lives. Computers are one of the most important elements to make our modern society. In this essay, I would like to address the development of computer technology by using brief history which is the transition of computers, and the significance of computers by examining their use in the areas of our daily lives and in business world. First of all, I would like to describe the developing history of computers because we use computers almost everyday and personal computers are one of the most important tools to make our lives more convenient. Personal Computers have the greatest influence to our daily lives. However we got Personal Computers only a few decades ago. Therefore I think it is necessary to introduce the history of computers before we get PC. According to Cheryl Price*, there are four major generations of developing computers. The first generation began in 1946 when the ENIAC system became operational. ENIAC stands for Electronic Numerical Integrator and Calculator and was built by the University of Pennsylvania. ENIAC is the significance because it is the first general purpose electronic computer system and also it was used for research, not commercial applications. The first computer was costing $US400.000 to build, funded by the US government. Also ENIAC weighed around 30 tones and stood two stories tall. It operated using 18.000 vacuum tubes and could perform 500 basic arithmetic functions per second. Moreover it had difficulty in handling alphabetic information and was programmed through an external plug board and it did not have the facility for magnetic storage. This meant that if the program needed to be changed it could only be done.
Computer literacy has increasingly become more important as society progresses. Knowledge of computers is now mandatary in many jobs. However how is IT nessesary, and how early should one learn computer literacy? Computer literacy is based on if you know how to use a computer. Skills then develop into how to use software, internet. Knowing how a computer functions, however is the next step up to computer literacy. It is vital that computer literacy becomes a requirement in university and colleges today. Our world is constantly become more computerized forcing people to work with them every day. It can only benefit them and there workplace or the people around them. The more people that are computer literate the more functional out world becomes. It would be smart to introduce computer skills right from the beginning. Opening computer's up to kindergartens allows them to become familiar with computers. Making a base is important and from there they can develop more skills in grade one and on. If we can train our younger generation to become familiar and computer literate we will be able to achieve higher standards in our industries. Therefore better results in our world around us. Information technology is more of a general term of a description to the skills required for today's students. Computer literacy is specific to the computer itself. Information technology can also refer to other technology including photocopy machines, fax machines, printers etc. This is also a good idea for students to learn however may not be a better description for computer literacy. It is important for one to have a well rounded knowledge and feel comfortable on the computer. They should be able to not only be able to type in a program but understand all it's functions. It is important for one to know how to use the internet and its search engines. Students should be taught the basics.
