Study Notes
Cloud Computing
- Cloud computing provides software and storage as an internet service, accessible with a web browser.
- Businesses benefit from cost savings in system design, installation, maintenance, and product/service launches, along with increased efficiency and remote access.
- Public cloud computing involves a service provider owning and managing infrastructure while organizations access shared hardware resources online.
- Data security is a significant concern in public cloud computing due to reliance on third-party safeguarding.
- Cloud computing services are categorized into three main types: Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS).
Operating Systems
- Operating systems utilize multitasking, multiprocessing, and multithreading to enhance processing efficiency.
- Not all operating systems support all task management approaches—for example, Windows, macOS, and general-purpose Linux lack support for real-time processing.
- File management involves the OS managing file and folder storage on devices using the “file system”, tracking file locations and access permissions.
- Memory management governs data storage in main memory by swapping data between RAM and disk, ensuring programs receive necessary memory without interference.
- Operating systems facilitate network communication, enabling data exchange and resource sharing among networked computers. Servers often have operating systems optimized for networking.
- User Interfaces (UIs) allow interaction with computer systems: command-line interfaces (CLI) require text commands, while graphical user interfaces (GUI) use icons and menus.
Integrated Development Environments (IDEs)
- IDEs offer an integrated package of tools essential for software engineering: code editors, compilers, debuggers, version control integration, and simulators/emulators for mobile app development.
- Common IDEs include Xcode, Visual Studio, and Eclipse.
- Mobile development IDEs provide simulators/emulators for virtual device testing, like Android Studio’s emulator and the Xcode Simulator for iOS.
Software Development Kits (SDKs)
- SDKs are collections of tools, libraries, and documentation that support application development for specific platforms.
- They are commonly offered by hardware, software, and cloud companies.
- Examples include Apple’s macOS SDK, iOS SDK, and watchOS SDK, as well as SDKs for Java: Android SDK, Apache Tomcat, AWS SDK for Java, Google Cloud SDK for Java, and Microsoft Azure SDK for Java.
Artificial Intelligence (AI)
- AI endeavors to automate tasks typically requiring human intelligence, encompassing fields like robotics, natural language processing, and computer vision.
- Machine Learning (ML) is a subset of AI that enables computers to learn from data without explicit programming.
- ML relies on data and algorithms, where data serves as the foundation for learning, and algorithms provide the structure for machine learning.
- ML encompasses various types, including supervised learning and generative learning (Generative AI).
Supervised Learning
- Supervised learning is a type of ML where the model is trained on labeled data.
- The goal is to learn a mapping from input to output.
- The process involves training data with input-output pairs, model training to predict output based on input, and prediction for new inputs.
- Applications include image classification and predicting house prices based on features.
Supervised Learning: Applications
- Supervised learning has numerous applications:
- Spam detection
- Medical diagnosis
- Fraud detection
- Financial forecasting
Supervised Learning: Example of Training Data
- Training data in supervised learning consists of input-output pairs, e.g., images paired with their corresponding categories.
Supervised Learning: Acquiring Data
- Data for supervised learning can be obtained through manual labeling, observing user behavior, or downloading from online sources like Hugging Face Datasets and Kaggle.
Summary
- The OS is crucial to computer operations, handling data input, processing tasks, and displaying results.
- Organizations rely on off-the-shelf software for common needs and develop custom software for specific requirements.
- Cloud computing has revolutionized software development by offering scalability, flexibility, and global access, facilitating innovation and adaptability.
- Machine learning extends software development by integrating adaptive, data-driven models into traditional rule-based systems, enabling learning and evolution over time.
