Computer programming

Computer programming is the process to make code of executable programs  or the process  that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis and generically solving problems resulting in an algorithm correction and its resource implementation of the algorithm in a target programming language, testing, debugging, and maintaining the source code, implementation of the build system. The purpose of programming is making a sequence of instructions that will automate performing a specific task or solve a problem. The programming requires expertise in many different subjects, including knowledge of the application, specialized algorithms, language programming. Source code is written in one or more programming languages such as C++, C#, Java, Python, PHP, Ruby On Real, Dhelpi etc.

The approach to software development may be must have fundamental properties :

Reliability : correction results of a program, its depends of algorithms and minimization of error handling and logic errors.

Robustness : anticipating error programming includes incorrect, inappropriate etc.

Usability : the program is easy  to use, make the user easy to understand, operating the program includes user interfaces etc.

Portability : the range of computer hardware and operating system platforms which the source code or program can be compiled, installed.

Maintainability : the ease which a program can be modified to make improvements or customizations, fix bugs to adapt it to new environments.

Performance : the amount of system resources a program consumes such us processor time, memory space, network bandwidth etc.

Informatics

Informatics is the practice of information that encompassing about computer science, human-computer interaction, information science, information technology and benefiting from computers. Informatics is the science of information,Informatics studies about the algorithms, behavior, interactions systems that stored, process, access, and communicate information.  it studies human computer interaction and how to using computer by well.

Informatics includes :

• Research and development of technologies need to implement information systems that enhance the cognitive abilities.
• Study of cognitive, social and economic impact of information systems.
• The development and using information systems in science, engineering, education, business etc and so much information can be stored digitally, it's can be manipulated by computer. 

Areas of computer science

Computer science has a range of topics from theoretical studies of algorithms and computation to the practical issues of implementing computing systems in hardware and software. Discipline of computer science areas : theory of computation, algorithms, data structures, programming, computer elements and architecture. also identifies fields such as software engineering, computer networking, data communication, database systems, distributed computation, computer-human interaction, computer graphics and operating systems.
