What is Computer Science: Computer science is the study of theory, experimentation, and engineering that form the basis of design and use of computers. Computer Science Engineering is the study of computers and computational systems. Unlike electrical engineers, computer scientists deal mostly with software and software systems; this includes their theory, design, development and application.

Necessary area of study within Computer Science and Engineering for bachelor of computer science include artificial intelligence, computer systems and networks, security, database systems, human computer interaction, vision and graphics, numerical analysis, programming languages, software engineering, ms in computer science, bioinformatics and theory of computing.

Even after knowing how to program is not enough for the study of computer science, it is only one element of the field. Computer scientists design and create algorithms to solve programs and study the performance of computer hardware and software. The issues that computer scientists encounter range from the abstract which is determining what problems can be solved with computers and the complexity of the algorithms that solve them, to the tangible which include designing applications that perform better on handheld devices, easy to use, and uphold security systems.

Bachelors of University of Maryland’s Computer Science Department are lifetime learners; they are able to adapt quickly all new frameworks and innovations in this evolving domain.

Although computer science has become an industrial activity, in many respects the success of a programming language is a subjective affair. It is based on solid theoretical foundations by providing a wide spectrum of programming paradigms. If one adds the simplicity of interaction with the language which the toplevel supports, that makes it a language perfectly adapted for teaching.
