Application of Computer

1. Business:
Computers are the part of the modern society. Modern business cannot survive without computers. In business computers are used to write letters keep employee records, communicate with the co-workers, prepare budgets and perform many other functions.
2. Medicine and Health Care:-
Computers are extensively used in medicine; it is used for diagnosing disease, monitoring the condition of patients and keeping the necessary records.
Many innovative medical applications use small, special-purpose computer. For example, pacemakers are computers that operate within the human body and help to maintain heart beat.
Also, laboratory tests such as X-RAY, CT-SCAN etc. are performed by computers.
3. Education:-
Computers have bought revolution in the field of education. Now computers are used in school and colleges by students, teachers and many others people use computers in library to read magazines and journals from the computer terminal rather than searching the shelves for paper originals..
Teachers use computers as a presentation tool, to explain difficult topics more clearly and easily to their students.
Students use computers to develop their computer projects and to do their mathematical problems.
Computer assisted learning (CAL) is used by students to improve their knowledge of any subjects
4. Space Technology:
It would be impossible to explore outer space without computers. Computers are used to accurate calculations for the spacecraft journey to moon, mars etc. the computer is also used to control the artifartificial satellites to know the weather patterns I earth. Now days the actual damage due to flood, earthquake, etc in particular area of earth is analyzed using satellite pictures.
5. Engineering:-
Engineers use computers to design the model of machines, vehicles, bridges, buildings etc. the design made with computers is more accurate and flexible than the design drawn with paper and pencil.
The design of complex structures such as aero planes, satellites etc. are almost impossible without computers.
6. Aviation:-
The computer is highly used in aviation. Modern aircrafts include sophisticated computerized instruments so that it can communicate with the ground airport stations; identify the status of its parts, fuel and available location in the atmosphere.
Thus. The use of computer has increased security in aviation.
7. Music and Entertainment:-
Computers have become a helpful tool for musicians. It helps them to create various electronic notes. Also the notes can be converted to music graphs. The composer can create the music of many musical instruments using a special keyboard called MIDI keyboard.
Computer games are the means of entertainment for people of all ages. Computers are heavily used in entertainment industry i.e. television, theater, films etc.
Films use special visual effects to make the content real. These effects are possible using computers. Computers have also improved cartooning and animations.
8. The Military:-
Military or defense services use computers massively. The actual development of computers is due to military. In 1964, ENIAC was created for the U.S. army. They used ENIAC for calculating accurate targets of missiles
Now, military uses more advanced computer technology. They use computers so o spy the enemy secrets such as enemy location, enemy numbers and their amount of weapons. They also use a special type of missile called “Smart Bomb” which embeds computer within it.
