并行數據傳送的特點是：各數據位同時傳送，傳送速度快、速率高，多用在實時、快速的場合。
并行傳送的數據寬度可以是1位～128位，甚至更寬，但是有多少數據位就需要多少根數據線，因此傳送的成本高。在集成電路芯片的內部，同一插件板上各部件之間，同一機箱內各插件板之間的數據傳送都是并行的。
并行數據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送方和接收方之間數據信息的傳輸是在單根數據線上，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。
串行數據傳送的特點是：數據傳送按位順序進行，最少只需要一根傳輸線即可完成，節省傳輸線。與并行通信相比，串行通信還有較為顯著的優點，傳輸距離長，可以從幾米到幾千米。在長距離內串行數據傳送速率會比并行數據傳送速率快，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，因此它在數據采集和控制系統中得到了廣泛的應用，產品也多種多樣。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（產品型號：485C、485A)甚至4800米（產品型號：G485EX）。
二 串行通信工作模式
通過單線傳輸信息是串行數據通信的基礎。數據通常是在兩個站（點對點）之間進行傳送，按照數據流的方向可分成3種傳送模式：單工、半雙工、全雙工。
