Study Notes
Client-Server Computing Models
- In earlier client-server computing models, the processing load for the application was shared between the client and server.
- The client handled the user interface and user input, while the server handled the business logic and data storage.
Upgrading Server-Side Code
- Upgrading the server-side code of an application typically required taking the server offline, updating the code, and then redeploying the server.
- This process could be time-consuming and may have resulted in application downtime.
Introduction of JavaScript
- JavaScript, introduced by Netscape, allowed programmers to add dynamic elements to the user interface running on the client side.
- This enabled a more interactive and responsive user experience.
Platform Dependencies
- Both the client and server components of applications were usually tightly bound to a particular computer architecture and operating system in earlier computing models.
- This meant that applications were often incompatible with different architectures or operating systems, making it difficult to develop cross-platform applications.
