Information System

Information system is the study of organizing data (create, collecting, process, and distribute data). Information system, an integrated of components for collecting, storing, and processing data for delivering information, knowledge. The study about business and computer science using information and computation foundation. Information system helps people to create, collect, process and distribute data using computer science include studying hardware, software and network.

Information System supports operations, management and decision making. It’s also used by people to interact with this technology in support of business processes. Information systems help to control the business processes. Information system is one of work system. A work system is a system in which humans,  machines do work using resources to process or produce a specific product or services. An information system supports processing information (capturing, storing, manipulating, displaying). Information systems with data systems monitor  the all activity systems includes communication system data process that stored on to use when needed.

Information System manages the operations, interacting with customers and suppliers, such us using information systems to reach potential customers over the Web and manage their human resources. For governments, they use information systems to provide effective services to citizens.

Information Science

Information science is a field that concerned with the analysis, manipulation, storage, dissemination of information etc. Information Science plays a vital role about everything we do in modern society. Information systems are vital to the operation of modern organizations and information scientists are involved in almost every field. People with information science skills are needed and many varied career opportunities in fields such as business, science, education, health, music , technology etc.  Practitioners within the field study and usage of knowledge in organizations between people and organizations, with the purpose of creating, improving, or understanding information systems.

Information science is considered a branch of computer science. It is an interdisciplinary field, not only aspects of computer science, but often used in fields such as archival science, commerce, communications, law, library science, management and the social sciences. Information Science used by the technology, people, and organizations. It has discipline and a focus on Information and Communication Technologies used by people to manage information within organizations.

The study of information includes activities such as information collection, processing, storage and presentation, communication of information etc. It also encompasses study of the information at the organizational and information systems that support information usage.

The Department of Information Science at any place or country focuses on any areas, such us : Human-computer interfaces, including multimedia systems, Information assurance and security, Information systems development and management, Computational modelling, machine learning and data mining, Databases, Distributed information systems, Social networking and organizational computing, Software engineering and application software development.

Computer Education

Generally, Computers are used in schools for writing, editing papers, designer or searching the Internet for information and also used almost everyone today. Computer skills is a subject being specifically taught in schools. When a graduate of such a program encounters a competing program they may be confused by the differences from what they learned. This is one reason why major computer firms such as Apple nor Microsoft consider the educational market. 

Graduates of computer education programs based around memorization, we may be heard asking things such as "where must I to click", and may need to pin paper notes for some computing tasks. Many users may need computer skills after years or decades of daily computer use. The primary factor preventing computer users from self-educating like losing data through doing the "wrong click”, poor motivation.

There are many books that cover various aspects of computer training, Computer Tutorials. There are also many websites that provide about computing education, computer tips, tricks Guides. For some teacher, lecturer while teaching their students may search information from the internet such us how to troubleshoot computers, fix security issues, set up networks, and use software.

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.
