Comp Addction

I-Introduction
A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a cpu and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. Also computer is a device, usually electronic, that processes data according to a set of instructions. The digital computer stores data in discrete unitsand performs arithmetical and logical operations at very highspeed. The analog computer has no memory and is slower than thedigital computer but has a continuous rather than a discrete input.The hybrid computer combines some of the advantages of digitaland analog computers
But for other people they think that computer are only use for playing browsing and other things that are not useful. Many people use computer for gambling trafficking and others they did not know how harmful is computer and how useful it is.
But first we should know the history of computer I will cite some example in computer evolution.

Here is the timeline
Computer evolution
1991 - World-Wide Web (WWW) was developed by Tim Berners-Lee and released by CERN.
1993 - The first Web browser called Mosaic was created by student Marc Andreesen and programmer Eric Bina at NCSA in the first 3 months of 1993
1994 - Netscape Navigator 1.0 was released Dec. 1994, and was given away free, soon gaining 75% of world browser market.
1996 - Microsoft failed to recognized the importance of the Web, but finally released the much imporoved browser Explorer 3.0 in the summer.
1998-Microsoft releases Windows 98.

2004-Mozilla Firefox 1.0 released, which later became Microsoft Internet Explorer's biggest competitor since Netscape Navigator.
2005-Intel releases the Pentium D, their first dual-core 64-bit desktop processor.
2006-Intel releases the Core brand. These are mobile 32-bit single-core and dual-core processors that were built using a modified design of the Pentium M's micro architecture.
2007-AMD releases the Phenom line of high performance processors, positioning the Athlon as a mid-range line.
2008-The first public beta version of the Google Chrome web browser was released. Chrome subsequently became the most popular web browser in the world, overtaking Internet Explorer.
2009-Microsoft releases Windows 7.

Importance of computer today, computers are used all over the world. We can find computers in houses, schools, offices, factories, companies and many other places. They are very useful to us as they can be used for many purposes. They have come to play an important role in our daily lives. So, we can say that the 21st Century is the age of computers and every student should have the knowledge of computer. A computer is an electronic machine and acts like the human brain. There are many advantages of using a computer. It can store, organize and find information. It can do calculations speedily. We can use computers to play games and watch films with CDs. Through computers, we can produce graphic designs, high quality printing services, logo creations, film editing and many others. We can link the computer with the Internet and do browsing or chatting. We can also send and receive e-mail from different parts of the world within a short period. The Information technology is the latest computer science. It is used as a global communication. We can look up more information on the websites. Nowadays, we, students, have the opportunity to learn our lessons through e-Education. The multi-media classrooms are well-equipped with computers and software. We can study lessons easily with the aid of computers. Pictures, drawings and tables can be drawn in the computers and we can use them at any time. Moreover, we can study many other subjects with the help of computers. Computer has become a very precious source and it is essential to know the importance of computer knowledge in education. So, we must learn to use the computer well. Today, there are many courses on computers and most of the young people are studying the Information Technology to observe the latest development in computer science. To keep abreast of the time, every student should gain the knowledge of computer and try hard to be proficient.
Computers are used daily in schools, hospitals, banks, government offices and many other businesses. In addition, individuals use computers daily to communicate by means of social media. In other hands Computers can help businesses by making their staff efficient and productive and also save their valuable time in any business or office. Computers in schools will help the learners to comprehend the basic concepts better with the help of video or audio examples. Computers in higher learning institutions will help the professors and researchers to do their work very fast and in an efficient and better way and also help them to share the same knowledge with their other members of staff. Computers become a vital gadget in several sectors; railways, banking, electricity, telephone departments, shopping carts etc are just but a few of them. Computers are also used in the medical industry to help doctors in diagnosing the diseases quickly and efficiently. All the administrative systems, whether private or public are now using computers and this practice can be evident in every part of the world.
How Computers Impact our Daily Life

"Computers are transforming society. Time is collapsing. Distance is no longer an obstacle. Crossing oceans takes only a mouse click."

This is the phrase of sentences I heard somewhere about computers. Virtually, computers which pressure most people's life are considered as the most important technological achievement of the XXI century. Using computers, we can make or solve most of difficult things which are hardly completed without their hands. Because of these different varieties of abilities, computers have been creating many noticeable achievements in most of societies? fields especially medicine, education, and usual life. In other words, these three fields also are computers? influences that I want to write in this essay today.

Firstly, there is a nonnegotiable point here that health services and art of medicine have been changed absolutely by computers in recent decades. Computers totally are able share the physician’s heavy duty which is save humans life. In deed since computers have been invented, new technological treatments that cooperate with computers have cured a thousand of patients. Eventually, there is nothing is more happy than come to life again. Formerly, once a doctor wanted to diagnose their patients, he or she mainly used to apply their experiences. Unfortunately, this process is doubted sometimes. And now, computers and other accessory machines are able to diagnose accurately with less time. In addition, computers have the other excellent benefit which is the ability in analyzing gene. Now scientists have more conditions to examine organic structures or to invent many new medicines, modern effective treatments which are very useful by using these gene technologies. Undoubtedly, the medicine’s current promotions closely connect with the development of computers. Therefore, we can agree unanimously that computers greatly influence our existent medicine.

Furthermore, Crossing oceans takes only a mouse click with computers, we no longer remain the conception about spatial distance. Actually the greatest advantage of computers is reducing distance and connecting people together. By this or other ways, computers thoroughly support and push up our education. Nowadays, students certainly stay at home but still can study for his or her bachelor degree. This actually seems to be impossible few decades ago. Those students just need to equip themselves with a computer connected internet at home only. This perfect utility is determined as computers? greatest success for humankind. For example, one student, a handicap person, who has his or her health’s problems, completely feels uncomfortable to go to school. Consequently, he or she can use study online programs as their best solution. Additionally, computers supply a lot of software which directly support to both teaching and learning. Today, with those specially designed software in mathematics, physics, and chemistry, students easily describe experiments and calculate complex equations which will be very difficult to solve before. As a result, what we receive today is instructors feel more convenient to teach, learners also feel more interested to understand lessons. The quality of the education was rapidly improved with computers contributions.

Eventually, computers come into every family and effectively influence our usual life. Families can use computers to talk to each other through email or other services of internet. Daily, I, many other international friends can use email to keep in touch with our families, and we realize that computers are very significant. Since, computers appear in our life, they are not only tools for working, studying but also entertainment. Now, we definitely listen to MP3 music with a hundred of beautiful songs, watch DVD films with digital standard or use drawing programs to create realistic images and animated displays much more easily than do them with traditional machines. Obviously, our standard life rapidly improves with computers appearance. Thus, if there is a technological achievement of the XXI century which most influence people’s life, that are computers.
