    Study Notes

    Operating Systems

    • API stands for Application Program Interface, it allows software to communicate with other software without understanding the inner workings of each other.
    • Multiuser allows multiple users to run programs concurrently on one computer.
    • Multiprocessing enables programs to run on more than one CPU.
    • Multitasking lets multiple programs run concurrently and seamlessly switch between them.
    • Multithreading allows different parts of a program to run concurrently, e.g., web browsers managing different tabs.
    • Real-time systems provide immediate responses to input.

    User Interfaces

    • Command Line Interface is a text-based interface using commands to interact with the computer.
    • Graphical User Interface uses icons and graphical representations for visual interaction.
    • Natural User Interface integrates gestures, voice commands, and touch for intuitive interaction.
    • Voice User Interface uses spoken language for interaction with devices, e.g., Siri and Alexa.
    • Brain-Computer Interfaces (BCI) are used for people with disabilities.

    Software Suites and Integrated Software Packages

    • Suites combine various single programs into a package, e.g., word processor, spreadsheet, database management, etc.

    Enterprise Application Software

    • Software Development involves creating custom software in-house for specific applications.
    • Software Acquisition involves buying off-the-shelf software from vendors to address common business needs.

    Cloud Service Providers

    • Provide software, data storage, and other services via the Internet.
    • Software as a Service (SaaS) delivers web-based business application software through subscriptions.
    • Major Cloud Service Providers include AWS, Microsoft Azure, and Google Cloud.

    Programming Languages

    • A programming language allows humans to communicate instructions to a computer.
    • Compiler translates source code into machine-language instructions.

    Integrated Development Environments (IDEs)

    • Combine tools necessary for software engineering, including a code editor, compiler, debugger, and version control.
    • Examples of IDEs include Xcode, Visual Studio, and Eclipse.

    Software Development Kits (SDKs)

    • A set of tools, libraries, and documentation helping developers create applications for specific platforms.
    • SDKs are usually offered by hardware, software, and cloud companies, such as Apple (macOS, iOS, and watchOS) and Java (Android, Apache Tomcat, AWS, Google Cloud, Microsoft Azure).
