Introduction to the Internet Ecosystem
The video introduces the internet ecosystem using the analogy of a multistory building. The basement represents hardware-related aspects like networking and computer architecture. The ground floor contains information and platforms for user interaction, such as subscriptions, likes, and comments. Higher levels involve companies utilizing the internet and website security measures. The layers are interdependent, requiring a clear understanding of hardware for effective development.
The Origins of the Internet
The internet's origin is discussed, noting it began with the internet portal, not the network itself. Initially, various protocols existed, but computers using different protocols couldn't communicate. To solve this, the TCPIP protocol was created as a central protocol, enabling seamless communication between different systems. This protocol is the foundation of the internet we use today.
Internet vs. World Wide Web
The video clarifies the difference between the internet and the World Wide Web. The internet is the underlying infrastructure, while the World Wide Web is a software that operates on top of it. Email is presented as another software that uses the internet, distinct from the World Wide Web, with its own protocols and systems.
Web Applications: Advantages
Web applications are highlighted for their accessibility and ease of use. Users don't need to install anything; they can access the application through the internet. This simplifies provisioning and eliminates the need to test software on different operating systems. Updates are easy to roll out, providing quick results.
Web Applications: Disadvantages and Security Concerns
The disadvantages of web applications include slower duplication and the necessity of an internet connection. Security is a major concern, as data transmitted over the internet needs to be secure to prevent privacy leaks. Storage and licensing of uploaded material, as well as potential compatibility issues with older devices, are also discussed. Additionally, limited access to local support sources and the need for additional cancer for less charity are noted as potential drawbacks.
