3 Computer Science Mr.Omer Salih Dawood

4 Computer Science Definition: Computer science (or computing science) is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Computer science began to be established as a distinct academic discipline in the 1960s Focuses on the process of computing through several areas of specialization, including theory, algorithms, data structures, programming concepts and languages. Mr.Omer Salih Dawood

17 Visual rendering (or Computer graphics) Computer graphics Image processing Mr.Omer Salih Dawood

18 Human-Computer Interaction Human computer interaction : The study of making computers and computations useful, usable and universally accessible to people, including the study and design of computer interfaces through which people use computers. Mr.Omer Salih Dawood

19 Scientific computing Bioinformatics Cognitive Science Computational chemistry Computational neuroscience Computational physics Numerical algorithms Symbolic mathematics Mr.Omer Salih Dawood

20 2. computer Engineering Definition: Computer Engineering (also called Electronic & Computer engineering or Computer Systems Engineering) is a discipline that encompasses broad areas of both electrical engineering and computer science Mr.Omer Salih Dawood

21 computer Engineering Algorithms Computer architecture and organization Computer systems engineering Circuits and signals Database systems Digital logic Digital signal processing Electronics Embedded systems Human-computer interaction Operating systems Programming fundamentals Social and Professional issues Software engineering VLSI design and fabrication Computer Networking Distributed Systems Advanced Database systems Mr.Omer Salih Dawood

22 Information Technology and Systems Information System: An Information System (IS) is the system of persons, data records and activities that process the data and information in a given organization, including manual processes or automated processes. Mr.Omer Salih Dawood

23 Applications of information systems Information systems deal with the development, use and management of an organization's IT infrastructure. The study of information systems, focuses on why and how technology can be put into best use to serve the information flow within an organization. Mr.Omer Salih Dawood

24 Decision support features MISDSSEISES Type of decision maker Many operational managers Individuals and Small groups of tactical managers Individual strategic manager Individual strategic, tactical, or operational manager Type of problemStructuredSemi-structuredUnstructuredStructured Type of information Pre-designed reports on Internal operations Interactive queries and responses for specific problems Online access to internal and external information on many issues Conclusions and recommendations for a particular complex problem Type of useIndirectDirect Phase of decision making IntelligenceDesign, choiceIntelligenceImplementation Mr.Omer Salih Dawood

25 Flow of Control Flow of control: Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace. Mr.Omer Salih Dawood

26 Batch and Interactive Processing Batch processing: collecting jobs in a single batch and then execute them without further interaction what the user. Interactive processing: Allows a program being executed to carry on a dialogue with the user through remote terminals. Requires real-time processing. Mr.Omer Salih Dawood
