An Internet company purchases a batch of TaiShan servers to build a Web system. C/S and B/S two architectures are available. Which of the following statement about the two architectures is correct?

• A.Compared with B/S, C/S architecture has the advantages of no need to install, easy to maintain, etc.
• B.Under the C/S architecture, the user interface is realized through the www browser, and very few things logic is realized on the front end (browser), but the main thing logic is realized on the server side, forming the so-called 3-tier structure.
• C.The B/S architecture can make full use of the advantages of the hardware environment at both ends, and reasonably allocate tasks to the client and server to achieve this, reducing the communication overhead of the system.
• D.Compared with the B/S architecture, the C/S architecture puts less pressure on the server.
