Study Notes
Ajax Technology
- Enables internet-based applications to perform like desktop applications.
- It solves transmission delays experienced by traditional applications due to data transfer between computer and server.
- Applications like Google Maps achieve excellent performance and resemble the look and feel of desktop applications due to Ajax technology.
Internet of Things
- Any object with an IP address capable of sending data automatically over the internet is considered a "thing."
- Examples include: cars with transponders, implanted heart monitors, smart meters, mobile apps tracking location, and smart devices.
Agile Software Development
- A set of methodologies aimed at faster software implementations and resource optimization.
- Emphasizes iterative development and continuous feedback.
Refactoring
- Reworking software to improve clarity and maintainability without compromising correctness and functionality.
- Widely used with agile development methodologies.
- Many IDEs offer built-in refactoring tools for automated reworking.
Design Patterns
- Proven architectures for constructing flexible and maintainable object-oriented software.
- Encourages reuse of recurring patterns to improve software quality, reduce development time, and minimize costs.
LAMP
- An acronym for Linux, Apache, MySQL, and PHP.
- A popular open-source technology stack for cost-efficient web application development.
- Equivalent for Windows is WAMP: Windows, Apache, MySQL, and PHP.
Software as a Service (SaaS)
- Software runs on servers accessible via the internet.
- Updates to the server benefit all clients globally without local installation.
- Examples include Salesforce.com, Google services, Microsoft Office Live, and Windows Live.
Platform as a Service (PaaS)
- Provides a computing platform for developing and running web applications.
- Users don't need to install tools locally, instead accessing them through the web.
- Providers include Google App Engine, Amazon EC2, and Windows Azure™.
Cloud Computing
- Utilizes data storage and processing on remote servers accessed via the internet.
- Enables flexible scaling of resources to meet demands and optimizes costs compared to local hardware purchases.
- Service providers handle software management, including installation, upgrades, security, backups, and disaster recovery.
TCP/IP
- Combined set of protocols responsible for communication over the internet.
- Developed from Transmission Control Protocol (TCP) used for communication over ARPANET.
- Ensures reliable delivery of messages by dividing them into packets with sequential numbering.
World Wide Web
- Collection of hardware and software associated with the internet, allowing users to access multimedia documents.
- Introduced by Tim Berners-Lee, who developed key technologies like HTML and HTTP.
- Aims to make the web universally accessible to everyone, regardless of disabilities, language, or culture.
Web Services
- Software components stored on a server accessible via the internet by other applications.
- Facilitate the development of mashups by combining complementary web services from different organizations.
- Accessible via web browsers, enabling portability across diverse platforms.
Software Development Kit (SDK)
- Contains tools and documentation used by developers to program applications.
Alpha Software
- Earliest version of a software product still under development.
- Often contains bugs, is incomplete, and unstable.
- Released to a limited number of developers for testing features and gathering feedback.
Beta Software
- Released to a larger group of developers after most major bugs are addressed and features are near completion.
- More stable than alpha versions, but still subject to change.
Release Candidates
- Feature complete, mostly bug-free, and ready for public testing.
- Used in a diverse testing environment to identify and fix remaining bugs.
Final Release
- Released to the general public after addressing bugs identified in the release candidate stage.
- Software companies typically distribute incremental updates over the internet.
