Imiphakathi emibili emincane ihlukaniswe ibanga elingamakhilomitha amathathu. Njengoba ingekho ingqalasizinda yezokuxhumana yesimanje, cabanga ngezindlela ezinhlanu izakhamuzi ezingasebenzisa ngazo imiyalezo ngokuphumelelayo.
Indlela yokuqala efika engqondweni ihilela ukuthwala imiyalezo ngezinyawo noma ngemoto ethile, bese uyidlulisela ngomlomo noma ngokubhala.  Enye indlela engase ihlanganise ukulethwa komyalezo ngokomzimba kungaba ukusebenzisa isimiso esithile somzimba ukuze sikudlulisele imiyalezo. Izibonelo zalesi simiso zihlanganisa izintambo ze-zip noma amashubhu e-pneumatic.  Enye indlela kungaba ukudlulisa umyalezo ngezwi, okuyinto kuleli banga engadinga umshini wokukhipha izimpawu onomsindo omkhulu, usizo lwendawo yokudlulisa yohlobo oluthile, noma ama-repeater endleleni.  Ukufaka ukwaziswa kwesigijimi kuyi-encoding bese sikudlulisela ngokubonakalayo kusinikeza indlela ehlukile. Lokhu kungaba ngesimo sokukhanya okukhanyayo noma izimpawu zomusi ngokwesibonelo.  Ekugcineni, kungasetshenziswa indlela ethile ebonakalayo eyisisekelo yokudlulisela ukwaziswa okufihliwe. Ngokwesibonelo, ikhebula eliqinile noma isimiso se-hydraulic esishintshashintshayo noma esishukumisayo singase sihunyushwe sibe ukwaziswa.
