World Wide web based on 3 tier architecture, not client server?


Recommended Posts

I have to answer the following question, could someone please give me advice on this?

"The world wide web is implemented based on a 3-tier architecture or N-tier architecture; whereas the Internet architecture is implemented based on a client-server architecture. Please explain why the world wide web cannot be implemented based on a client-server architecture. "

The terms "client" and "server" are quite ambiguous.

If you are looking for information, you are a client. If you have the information, you are a server.

So, looking for something makes you the client, and having it makes you a server.

But if the server your client first communicates with doesn't have the information, then it (the server) has to have a way to find it- thus creating the DNS system.

You have just transitioned from a pure client-server system to an N-tier system. DNS provides a way for a server to escalate and translate server location 'seemlessly' across the network.

And now the CS majors will come in and correct me.

I'm not an expert, but in client-server, the server really has a lot of work to do with modern content that often relies on processing information from a database and such.

With multi-tiered, there is more than one server, with functions divided up: for example, the database backend is running on one server, and the content (including results of database queries) is delivered generally through what I guess would be the main server for the application (and there can be several of these working together, but doing the same function, really, so I don't think that alone would count as multi-tier).

The benefit of multi-tier is that is very scalable. Add in more database servers if you have very heavy database requirements, and so forth.

As far as why the www "cannot" be implemented as a pure client-server, I guess that it really could, but the dynamic content would have to be processed by the same machines handling all the incoming requests. That could bring a popular site/server to its knees quickly. I don't think it would be practical.

I am sure that others with degrees in this sort of thing can give you a much better answer shortly.

EDIT: tao already beat me to the post, and he considers also the DNS servers, which I neglected.

This topic is now closed to further replies.

    • Surface Copilot+ PCs coming to classrooms from July 22, turbocharged with on-device AI by Paul Hill Microsoft has announced that it’s launching the new Surface Pro 12-inch and Surface Laptop 13-inch models specifically for education customers from July 22. The Redmond giant said that these devices are being launched as a direct response to feedback from educators who want practicality and ease of use in their diverse classrooms. These are both Copilot+ PCs so teachers and students will be able to leverage the latest AI features thanks to the dedicated Neural Processing Units (NPUs) that allow for on-device AI. The on-device AI, aside from delivering well-known features like Recall, will enable new education features such as a new app Microsoft is working on called Microsoft Learning Zone. Microsoft Learning Zone will allow teachers to create personalized lessons by adapting content from trusted sources like OpenStax, generating interactive games with Kahoot, and tracking students progress. Microsoft expects this to help teachers save time and deliver a more flexible and engaging classroom. Another AI feature that will be available is Click to Do. This lets students highlight text or images and get contextual help. It can be used to summarize a paragraph or explain a graph. To activate it, students can press the Windows key and click. This feature runs entirely on device so inputs to the AI are secure and you don’t need to ever worry about third-parties seeing. Finally, these devices will also have accessibility features such as Voice Access which lets you navigate with speech and Live Captions which provide real-time subtitles and translations for spoken content. These make the devices more inclusive for students with disabilities. Regarding security, these laptops come with the Microsoft Pluton security chip directly integrated into the processor for protecting sensitive data. It can protect data such as passwords and sign-ins, even if your device is stolen. Thanks to automatic Windows Updates, schools never need to worry about falling behind on updates either. With the impending demise of Windows 10 in mid-October, these Surface devices arrive just in time for schools looking for somewhere to upgrade to. Aside from AI features and security, Microsoft is also pushing other key features including easy repair with replacement components at the Microsoft Store and iFixit, their lightweight design and all-day battery life making them ideal for carrying and surviving the school day, and their compatibility with popular education apps such as TestNav, Google Classroom, Minecraft Education, and Adobe Express.
