Browser Server Mode Explained | Generated by AI
Question: The browser/server mode can also be described as which of the following?
A. C/S mode
B. B/S mode
C. P2P mode
D. P2C mode
Answer:
The correct answer is B. B/S mode
Detailed Explanation:
B/S mode stands for Browser/Server architecture (浏览器/服务器模式).
It is the dominant network application architecture used on the modern web, especially since the rise of the World Wide Web.
Key characteristics of B/S mode:
-
Client side = Web browser (Chrome, Edge, Firefox, Safari, etc.)
→ The browser is the only software users need to install on their device.
→ No custom client software needs to be developed or installed for most web applications. -
Server side = Web server (Apache, Nginx, IIS, etc.) + application logic + database
→ All core business logic, data processing, and storage happen on the server.
→ The server generates dynamic HTML/CSS/JavaScript (or delivers static content) that the browser renders. -
Advantages of B/S over other modes (especially compared to C/S):
Feature B/S (Browser/Server) C/S (Client/Server) Client installation None (just a browser) Requires installing dedicated client software Cross-platform support Excellent (any device with a browser) Usually platform-specific or needs multiple versions Updates & maintenance Only server needs updating Must update both client and server Development cost Lower (unified client = browser) Higher (need to develop/maintain client apps) Deployment speed Very fast (users access via URL) Slower (requires client installation)
Why the other options are incorrect:
-
A. C/S mode (Client/Server)
→ This is the traditional thick-client model (e.g., early desktop applications like QQ early versions, most ERP software before web era, many games).
→ Requires installing a dedicated client program → not the same as browser/server. -
C. P2P mode (Peer-to-Peer)
→ Decentralized model where nodes act as both client and server (e.g., BitTorrent, some blockchain networks, early Skype).
→ Completely different from browser/server. -
D. P2C mode
→ Not a standard or widely recognized architecture term in networking.
→ Sometimes jokingly or mistakenly used, but it has no official meaning in this context.
Exam key point (very frequently tested in Chinese IT/networking exams):
- C/S = Client/Server → thick client, dedicated software
- B/S = Browser/Server → thin client, web browser only
- Modern web applications (most websites, SaaS like WeChat Work, DingTalk, cloud office tools, online banking, etc.) use B/S mode
Your previous answer A (C/S) was incorrect because browser/server specifically refers to B/S, not the older C/S model.
Correct answer: B. B/S mode
