Echo-back interferes with the original signal
BUS topology
A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
A thin coaxial cable that is used as a connector is also called a thinnet. It is popular in linear bus networks.
The unterminated end presents an impedance mismatch or 'bump'. This causes a reflection of the original signal to propagate back down the bus, which destructively combines with and degrades the desired waveform. For this to be avoided, the bus must be terminated with a resistance equal to its characteristic impedance.

Bus Cable
10BASE2 is a variant of Ethernet that uses thin coaxial cable. The 10 comes from the maximum transmission speed of 10 millions of bits per second, The BASE stands for baseband signaling, and the 2 supposedly refers to the maximum cable length of 200 meters.
If the ends of a bus topology network are not terminated then you will get 'signal bounce'. This will cause all packets to collide with each other, and the net effect is that the network is unusable.
Local Area Network Cable usually associate with a bus topology network. In a Bus topology network simple LAN cables are used with LAN Hubs ( i.e. having a collection of LAN ports ) which in turn connect many systems with the server systems. LAN cables are available in various length ranging from 1meter onwards.
