集線器的工作原理： 集線器并不處理或檢查其上的通信量，僅通過將一個端口接收的信號重 復(fù)分發(fā)給其他端口來擴展物理介質(zhì)。所有連接到集線器的設(shè)備共享同一 介質(zhì)，其結(jié)果是它們也共享同一沖突域、廣播和帶寬。因此集線器和它 所連接的設(shè)備組成了一個單一的沖突域。如果一個節(jié)點發(fā)出一個廣播信 息，集線器會將這個廣播傳播給所有同它相連 的節(jié)點，因此它也是一 個單一的廣播域。

采用后一種方法時，編程者要為每一角色設(shè)計一個智 能系統(tǒng)（一個模塊）來進行控制，這個智能系統(tǒng)（模塊）開始什么也不 懂，就像初生嬰兒那樣，但它能夠?qū)W習(xí)，能漸漸地適應(yīng)環(huán)境，應(yīng)付各種 復(fù)雜情況。這種系統(tǒng)開始也常犯錯誤，但它能吸取教訓(xùn)，下一次運行時 就可能改正，至少不會永遠錯下去，用不到發(fā)布新版本或打補丁。利用 這種方法來實現(xiàn)人工智能，要求編程者具有生物學(xué)的思考方法，入門難 度大一點。但一旦入了門，就可得到廣泛應(yīng)用。由于這種方法編程時 無須對角色的活動規(guī)律做詳細規(guī)定，應(yīng)用于復(fù)雜問題，通常會比前一 種方法更省力。
