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).
