1756-A10/ABPLC模塊
具有通信功能的單機系統(tǒng)。該系統(tǒng)稱為終端，是早期計算機網(wǎng)絡(luò)的主要形式，它是將一臺計算機通信線路與若干個終端直接相連
2．具有通信功能的多機系統(tǒng)。在簡單的“終端——通信線路——計算機”這樣的單機系統(tǒng)中，主計算機負擔(dān)較重，既要進行數(shù)據(jù)處理，又要承擔(dān)通信功能。
3．以共享資源為主要目的的計算機網(wǎng)絡(luò)。既利用通信線路將多臺終端設(shè)備連接起來，實現(xiàn)設(shè)備與設(shè)備之間的通信。
4．局域網(wǎng)絡(luò)及其互連為主要支撐環(huán)境的分布式計算階段。局域網(wǎng)是繼遠程網(wǎng)之后發(fā)展起來的小型終端設(shè)備網(wǎng)絡(luò)，它繼承了遠程網(wǎng)的分組交換技術(shù)和計算機的I/O總線結(jié)構(gòu)技術(shù)。并具有結(jié)構(gòu)簡單、經(jīng)濟實用、功能強大、方便靈活等特點。是隨著微型計算機的廣泛應(yīng)用而發(fā)展起來的。
