并行數(shù)據(jù)傳送的特點是：各數(shù)據(jù)位同時傳送，傳送速度快、速率高，多用在實時、快速的場合。
并行傳送的數(shù)據(jù)寬度可以是1位～128位，甚至更寬，但是有多少數(shù)據(jù)位就需要多少根數(shù)據(jù)線，因此傳送的成本高。在集成電路芯片的內(nèi)部，同一插件板上各部件之間，同一機箱內(nèi)各插件板之間的數(shù)據(jù)傳送都是并行的。
并行數(shù)據(jù)傳送只適用于近距離的通信，通常小于30CM。
2．串行通信
串行通信是指通信的發(fā)送方和接收方之間數(shù)據(jù)信息的傳輸是在單根數(shù)據(jù)線上，以每次一個二進制的0、1為最小單位逐位進行傳輸，如圖２所示。
串行數(shù)據(jù)傳送的特點是：數(shù)據(jù)傳送按位順序進行，最少只需要一根傳輸線即可完成，節(jié)省傳輸線。與并行通信相比，串行通信還有較為顯著的優(yōu)點，傳輸距離長，可以從幾米到幾千米。在長距離內(nèi)串行數(shù)據(jù)傳送速率會比并行數(shù)據(jù)傳送速率快，串行通信的通信時鐘頻率容易提高，串行通信的抗干擾能力十分強，其信號間的互相干擾完全可以忽略。但是串行通信傳送速率比并行通信慢得多，并行通信時間為T，則串行時間為NT。
正是由于串行通信的接線少、成本低，因此它在數(shù)據(jù)采集和控制系統(tǒng)中得到了廣泛的應(yīng)用，產(chǎn)品也多種多樣。RS-232的通信距離一般為15米，波仕電子的RS-232可以達到500米（產(chǎn)品型號EX232）以上。RS-485的通信距離一般為1200米，波仕電子可以做到1800米（產(chǎn)品型號：485C、485A)甚至4800米（產(chǎn)品型號：G485EX）。
二 串行通信工作模式
通過單線傳輸信息是串行數(shù)據(jù)通信的基礎(chǔ)。數(shù)據(jù)通常是在兩個站（點對點）之間進行傳送，按照數(shù)據(jù)流的方向可分成3種傳送模式：單工、半雙工、全雙工。
