Switched communications networkA switched communications network routes data from source to destination via a network of nodes. There are two methods for switching.
Broadcast networkA broadcast network avoids the complex routing procedures of a switched network by ensuring that each node's transmissions are received by all other nodes in the network.
Network accessThis type of communication, known as multiple access, can be established through channel scheduling or through random access.
Scheduled accessTime-division multiple access (TDMA) scheduling assigns a time slot to each node in turn, which uses the slot if it has something to transmit.
Random accessRandom-access algorithms were created specifically to provide nodes with something to transmit with faster channel access.
