Chapter 4 Computer Software - Coggle Diagram

- - - - Cloud computing is a style of computing in which software and, in some cases, virtualized hardware resources are provided as a service over the Internet
  - - - The two main categories available to computer users
        are application software and system software
    - - Software is the general term for a myriad of programs used to operate and manipulate computers and their peripheral devices or to perform a specific task using a computer as the vehicle
- - - - XML (eXtensible Markup Language) is not a Web page format description language like HTML.
    - - Java is an object-oriented programming language created by Sun Microsystems that has revolutionized the programming of applications for the Web, as well as corporate intranets and extranets.
    - - HTML (Hypertext Markup Language) is a page description language that creates hypertext or hypermedia documents.
    - - Web services are software components that are based on a framework of Web and object-oriented standards and technologies for using the Web that electronically link the applications of different users and different computing platforms.
  - - - Assembler languages (or second-generation languages ) are the next level of programming languages.
    - - High-level languages (or third-generation languages ) use instructions, which are called statements , that include brief statements or arithmetic expressions.
    - - The term fourth-generation language describes a variety of programming languages that are more nonprocedural and conversational than prior languages.
    - - Machine languages (or first-generation languages ) are the most basic level of programming languages.
    - - Object-oriented languages like Visual Basic, C11, and Java are also considered fifthgeneration languages and have become major tools of software development.
  - - - Multitasking (sometimes referred to as multiprogramming or timesharing) is a task management approach that allows for several computing tasks to be performed in a seemingly simultaneous fashion
  - - - System Development Programs. Programs that help users develop information system programs and procedures and prepare user programs for computer processing. Major software development programs are programming language translators and editors, and a variety of CASE (computer-aided software engineering) and other programming tools. We will take a closer look at CASE tools later in this chapter.
      - System Management Programs. Programs that manage the hardware, software, network, and data resources of computer systems during the execution of the various information processing jobs of users. Examples of important system management programs are operating systems, network management programs, database management systems, and system utilities.
