What is Computer Science?

Computer science is the subject and complete and a vast field.it is the study of computers and interrelated fields. The Earliest struggle and research of the renowned scientists led to the invention of the modern   computer technology. In early era  Abacus is used for calculation, multiplication, Addition, Division, subtraction, by the invention of modern computers these calculations become so easy that even millions of calculations are done in Micro seconds by using modern computer technology. Charles Babbage was a person who founded the first computing machine. Computer science is a discipline that includes theory and practice. Nowadays,  everyone is a user of computer, and many people are even programmers. We give instructions to the computer which is called input and computer processes the information and give us the desired output. But computer science can also be used on a higher level, as a science of problem solving, in the research field, for weather forecasting and for military based security systems and in the field of Robotics. Computer scientists develop a model or in technical term they developed a case study of the problem and handover to the analysts who analyze and gather data related to the problem at the end programmers or software engineers implement for the solution of problem and make software which facilitates the layman.it includes the study of both hardware and software. Computer scientists must also be able to design solutions and verify that they are exactly  correct. Problem solving methodology requires accuracy, creativity, and careful reasoning. Many problems in general science, engineering, healthcare, business, and other areas can be solved timely with computers Thus; computer scientists often become expert in other subjects.computer science has a wide range of specialties.these include software,graphics effects, artificial intelligence(robots), software engineering techniques, operating system concepts, IT field, Bioinformatics methods Algorithm and data structures  , Graphics ,Visualization and robotics technology.
