History is round, it is not fake.
Before the PC appears, people are using thin clients, and there is no processing capability on the terminal on the large host, only responsible for displaying and input, all actual work is handed over to the server, which is of course a thin client.
Then the PC appears, when the PC is also connected to the network, people find that the processing power of the PC can alleviate the burden on the server, so the C / S mode appears. All resources are fully utilized, and the distributed calculation has appeared, and the history forwarded a big step forward.
However, the Internet appeared again, and people began to yell on thin clients. Pentium 4's processor is not used, 1G memory is not rare, 80G hard drive also passes, all processing is handed over to the server, and the client is full of browsers. It's a history of history. Why, it turned out to be a money, and the client's deployment maintenance cost is too high. Also, everyone earns some money is not easy. If the whole consumption is on dealing with the customer complaining, it is not worth it, so everyone is saved, saves some money, and the thin client is all changed.
But the history of the history is still rolling forward, and the Smart Client has appeared. The problem of deploying maintenance is solved, no more money, then put the Pentium 4 CPU is not useful, will not cost it.
The just large amount of software advertisement is also migrating from the CS to the BS, the BS is already walking down the road. The new CS mode is secretly rising. Not you don't understand, this world is fast. You see, OFFLINE Application Block comes out http://msdn.microsoft.com/architecture/application/default.aspx?pull=/library/en-us/dnpag/html/offline.asp
