DECnet
v1 v2 3 3 4 4 == The node == 5 In DECnet slang computers (and other devices) are called 'nodes'. They have an address and an name. The name consists of six char like 'mynode' or 'homepc'. The node address consists of two parts. The first one is known as the area and the second as node part. The area part has six bit so it is a number from zero to 63. The node part is an ten bit integer from zero to 1023. Both parts are separated by an dot like this: 1.7, 44.88, 12.740. 5 In DECnet slang computers (and other devices) are called 'nodes'.

Area and node part must not be zero for real nodes. Zero area and node part is reserved for special things. 6 6 7 7 The area is the local group of nodes in an segment of the network. Normally this maps to the physical segment (read: LAN). Nodes within one area can talk to each other directly. In the following document we assume all nodes are within the same area.
