Computers are, without second thought, a useful tool that many of us use daily. Since their invention, people far and wide have become increasingly dependent on it. As a matter of fact, the most ancestral computer, the abacus, is used by both Mesopotamian and Chinese empires in computing collected taxes from their territories. In the 17th century another invention rose. This is the Pascaline, a mechanical machine that adds millions in a matter of seconds, which is in invented by Blaise Pascal to help the French government calculate tax income from the Frenchmen and its territories. After that is the rise of the giant computers is used electronically by International Business Machines Corporation and as time pass these giants shrink in size and turned into tablets used to calculate numbers, send message and call someone in the globe. Computers have found their way into ever aspects of our life and in some cases; they make things easier for us. But as we increasingly rely on computers to get through the day, the question begs to be asked; is this dependence on computers a good thing or should we be more suspicious on their benefits?
Computers make our lives easier and give us new ways to learn about the things we're interested in. They make it possible to do many things from the comfort of our own home -- we can shop online, keep in touch with our friends, online, even go to school online. They make it easier to record and organize information and entertain us with a nearly endless variety of games.
Medical science is fully dependent on computers. All medical operations and are controlled by computer. Computer software is used for diagnosis of diseases. It can be used for the examination of internal organs of the body. Advanced computer-based systems are used to examine organs of the body. Some of the complex surgeries can be performed with the help of computers. Computer-assisted Surgery (CAS) is a fast-advancing field in medicine, which combines medical expertise with computer intelligence to give faster and more accurate results in surgical procedures. In CAS, a model of the patient is created, and then analyzed prior to surgery. The surgical procedure is simulated on the virtual image of the patient. The surgery can then be performed by a surgical robot, as programmed by a medical professional or the robot may only assist doctors while they do the actual surgery. In both cases, computer intelligence is at work, thus underlining the uses of computers in medicine.
The modern communication system is fully based on computers. We can’t think of a communication system without computers. Since communication has very important role in society as well as organization and enterprises it is necessary that we should have an accurate and fast method for communication. Here we need computers to provide fast and efficiency manner for communication. Now we have mobile phones, e-mails, fax and other many methods for providing good way to communicate each other which cannot develop and work without computers. Let us take the working of an organization. The communication between each level between two or more organizations is carrying through computers. If there is no computers it should cause big wastage of time may cause wastage of data and so many other things. Likewise computer based communication is necessary at every field whether it is hospitals or industry or government. Without computers there may be large wastage of time, money and resources which may cause great damages.
Hence computer is necessary in communication and without that it is impossible to provide a best way that fulfills the present requirements.
Today, we are able to chat and see anyone from anywhere of the world. So, the more we will use computer, the easier will be our life and our science and technology will be more developed.
Despite the many benefits of computers, there are also a number of arguments against them, one of which is the negative effect some believe they are having on children's education. Computers are a threat to our health. Long-term exposure to radiation increases the risk of all forms of cancer, tumors, blood disorders, miscarriage, headaches, insomnia, anxiety, aging of the skin, skin burn, etc. Radiation exposure over time can cause skin burn, dry wrinkled skin and photo aging. This skin damage is identical to sun damage and causes the same health problems. Many electronic products that we use on a daily basis expose us to harmful radiation. A television, microwave oven, cellular phone and computer are examples of products that emit radiation. Computer radiation is most harmful to skin health when sitting directly in front of the computer for long periods of time with our face absorbing the radiation. Computer radiation can make you feel sick and burn your skin. Most people are not aware of this, and continue to suffer with ill health they have no explanation for. They do not realize sometimes ill health is related to computer use. Using a laptop or LCD does not exclude you from the negative health affects of computer radiation. All computer monitors emit low levels of radiation. Laptops and LCD monitors emit less radiation than the old-fashioned CRT monitors. However, all monitors emit enough radiation that affects your health and appearance.
In the past few years, many teachers have taken to shuffling their students off to a computer to type out short, quick assignments that could easily be written out by hand. While this isn't much of an issue for older students, it is an issue for the younger students who are just learning to read and write. Regardless of how much we're coming to rely on computers, printing and handwriting are a necessary skill to have. But typing out assignments has affection more than just the ability to print -- it can also negatively impact on their spelling and grammar. While most programs now have spell- and grammar-check, they are not infallible; they cannot differentiate between homonyms and will often suggest corrections that are not, in fact, correct. Furthermore, information is often more easily and accurately remembered when children have to spend a little time writing it out by hand, rather than a few quick minutes typing away at a keyboard. Another case against computers crops up when a person's interest in computers goes too far and becomes an obsession. However, it's still important to maintain a life outside of the cyber world; a life spent attached to a computer screen isn't areal life. When a computer becomes the central point of a person's life, they undergo a change in behavior; they become lazy and develop anti-social tendencies, and, in some severe cases, simply cannot function without a computer. It's a common thing to see with children who have been allowed to spend too much time on the computer, watching movies, or playing video games: when it comes time to walk away, they throw temper tantrums. But it's not just a matter of behavioral changes -- when a person can't tear themselves away from the screen long enough to take part in any other activity, it can take a toll on their comfort and health. They may experience weight gain, strained eyes, and headaches, among other unpleasant side-effects. However, it can also be argued that this is not the fault of the computer, but rather the fault of the person. Perhaps the most convincing argument, however, is the issue of safety. Aside from the issue of sharing personal information such as full names and addresses, there is also the bigger issue of stolen personal information. As our dependence on computers grows, so does our comfort level with them, and we are more likely to save personal information to our computer. While it would be nice to think that it is always perfectly safe to do so, the fact is that there are people who have any number of ways to gain access to your personal files, and therefore, any personal information stored on your computer. Even if you don't knowingly keep any personal information on your computer, if you bank or shop online at all, it's possible for someone who knows what they're doing to gain access to delicate financial information.
In this computer era, there must be people that are too dependent on computer. But, we should not be too much dependent on computers as it causes threats for human being. We have minds that function well and bodies that move efficiently. Minds and bodies given by God and will return to God. Computers are not the “the Savior” that save as from despair and destruction. We can never rely on computers, so we must learn how to rely to ourselves and to Him.
