Uses of computer & related resources. The influence of computers is universal. Computers are used in applications ranging from running a farm, diagnosing a disease, and designing to constructing and launching a space vehicle. Because the development of computers has been largely the work of scientists, it is natural that a large body of computer applications serves the scientist. To solve scientific problems researchers must deal with the language of science: mathematics. To understand more deeply complex natural phenomena, scientists must use complex mathematical relationships and volumes of data too impossible to manage without the aid of computers. Many scientific computer programs serve the entire population. The links included herein relate to computers and their uses.
Computers can be used in literally any field, limited only by the imagination of its programmers and the ingenuity of its associated hardware engineers.
Here is a very abbreviated list of applications for computers:
Flight simulation - to teach pilots how to fly without wasting expensive planes.
Automated industrial monitoring and control - to watch processes and warn an operations staff when something is deviating from parameters.
Geoseismic surveying - to capture acoustic reflections from a survey boat and at the same time perform ultra-precise navigation so that it is possible to correlate the reflection data with a latitude and longitude. (I've worked this industry for a while.) Twenty years ago we could get your position to within 1.5 meters anywhere in the Gulf of Mexico WITHOUT special equipment. With special calibrated transponders, we could get to less than 1 meter precision - without using the military navigation signals that are the basis for ultra-precise GPS.
Medical industry: Computers are part of electrocardiogram machines, monitoring wave-forms and doing "shape" analysis even as the trace is being recorded.
Retail sales: A point-of-sale terminal is a combination of a cash register and an inventory tracking tool.
Entertainment: Your DVD player is a computer. Your cable box has a computer in it. Your TV has a computer in it. Your CD player has a computer in it. Heck, your remote control unit probably has a little smart chip in it too.
Weather forecasting: Every prediction these days is based on the average of about 20 computer models for weather.
If you can imagine it, someone can do it.
"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 human’s 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
Uses of Computers in Medicine
What is the importance of computers in medicine? How can computer technology be harnessed in the medical field? Read on to find the answers.
Computers play a key role in almost every sphere of life. They facilitate storage of huge amounts of data, they enable speedy processing of information and they possess an inbuilt intelligence. Owing to these unique capabilities, computers function on levels close to that of a human brain. Computers can hence be employed in a wide variety of fields like engineering, data processing and storage, planning and scheduling, networking, education as well as health and medicine. You might want to take a look at the various uses of computers.
Computers are the excellent means for storage of patient related data. Big hospitals employ computer systems to maintain patient records. It is often necessary to maintain detailed records of the medical history of patients. Doctors often require the information about a patient’s family history, physical ailments, already diagnosed diseases and prescribed medicines. This information can be effectively stored in a computer database.
Computers can keep track of prescriptions and billing information. They can be used to store the information about the medicines prescribed to a patient as well as those, which cannot be prescribed to him/her. Computers enable an efficient storage of huge amounts of medical data.
Medicine comprises vast base of knowledge. Computer storage can serve as the best means of housing this information. Medical journals, research and diagnosis papers, important medical documents and reference books can best be stored in an electronic format.
Many of the modern-day medical equipment have small, programmed computers. Many of the medical appliances of today work on pre-programmed instructions. The circuitry and logic in most of the medical equipment is basically a computer. The functioning of hospital-bed beeping
systems, emergency alarm systems, X-ray machines and several such medical appliances is based on computer logic.
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 delicate organs of the body. Some of the complex surgeries can be performed with the aid of computers. The different types of monitoring equipment in hospitals are often based on computer programming.
Medical imaging is a vast field that deals with the techniques to create images of the human body for medical purposes. Many of the modern methods of scanning and imaging are largely based on the computer technology. We have been able to implement many of the advanced medical imaging techniques, thanks to the developments in computer science. Magnetic resonance imaging employs computer software. Computed tomography makes use of digital geometry processing techniques to obtain 3-D images. Sophisticated computers and infrared cameras are used for obtaining high-resolution images. Computers are widely used for the generation of 3-D images in medicine.
Computer networking enables quicker communication. Computers and Internet have proved to be a boon in all the spheres of life. In the field of medicine, computers allow for faster communication between a patient and a doctor. Doctors can collaborate better over the Internet. Today, it is possible to obtain experts’ opinions within seconds by means of the Internet. Medical professionals sitting on opposite sides of the globe can communicate within minutes by means of the Internet. It is due to computer networking technology that network communication has become easy. Medical practitioners can discuss medical issues in medical forums. They can exchange images and messages in seconds and derive conclusions speedily. They can seek advice and share knowledge in a convenient manner over the Internet.
Role of computers used in medicine, uses of computers in health care and importance of computers in medicine fields. The influence of computers is universal. Computers are used in applications ranging from running a farm, diagnosing a disease, and designing to constructing and launching a space vehicle. Because the development of computers has been largely the work of scientists, it is natural that a large body of computer applications serves the scientist.

Medical imaging techniques help doctors locate and evaluate a tumor. These include computed tomography (CT) and magnetic resonance imaging (MRI) scans. CT and MRI scans use computers to form a three-dimensional image of the tumor and surrounding tissues. X-ray images of the breast called mammograms help physicians detect and evaluate breast cancer. Ultrasound scanning bounces high-frequency sound waves off a tumor and surrounding tissue to create an image of the tumor. The multimodality display technique combines the images from several imaging tools into one picture, providing a final three-dimensional image with much greater detail. Computer-aided diagnosis uses complex computer programming technology called artificial intelligence to scan mammograms and X rays to help look for signs of cancer and offer an automated second opinion. The importance of computers cannot be stressed enough as computer technology has revolutionized the field of medicine.

USES OF COMPUTERS IN BANKING:
All financial transactions are done by computer software. They provide security, speed and convenience
The term "electronic banking" or "e-banking" covers both computer and telephone banking. Using computer banking, a charity’s computer either dials directly into its bank's computer or gains access to the bank’s computer over the internet. Using telephone banking, the charity controls its bank accounts by giving the bank instructions over the telephone. Both computer and telephone banking involve the use of passwords which give access to the charity’s accounts.
Using these methods, banking transactions can be actioned 24 hours a day. Computer banking allows a charity, for instance, to view recent transactions, print out statements and transfer funds between accounts and make payments. Many banks also have the facility for a charity to set up, amend or cancel standing orders. Electronic banking also allows payments to be made to the charity, i.e. acceptance of credit card donations. Most charities that use electronic banking will also continue to use some of the elements of more traditional methods of banking, such as a chequebook.
Electronic banking services differ between the different banks and building societies. If trustees decide that they want to use electronic banking then they should shop around for the most suitable package for their charity.
• Electronic banking, also known as electronic fund transfer (EFT), uses computer and electronic technology as a substitute for checks and other paper transactions.
ATM:
• Automated Teller Machines or 24-hour Tellers are electronic terminals that let you bank almost any time.
• To withdraw cash, make deposits, or transfer funds between accounts, you generally insert an ATM card and enter your PIN.
• ATM use is increasing over the years.
DIRECT DEPOSIT:
Direct Deposit lets you authorize specific deposits, such as paychecks and Social Security checks, to your account on a regular basis.
PC BANKING:
Personal Computer Banking lets you handle many banking transactions via your personal computer.
You may use your computer to view your account balance, request transfers between accounts, and pay bills electronically.
Point-of-Sale Transfers:
Lets you pay for purchases with a debit card, which also may be your ATM card.
Computers have leapfrogged the human society into another league. It is used in each and every aspect of human life. They will spearhead the human quest of eradicating social problems like illiteracy and poverty. It is difficult to imagine a world bereft of computers. This revolutionary technology is indeed a boon to the human race. May computers continue to shower their blessings to us.
