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.
The type of network that uses terminators and T-connectors is the coaxial cable network, particularly in a bus topology. In this setup, T-connectors are used to connect devices to the main coaxial cable, while terminators are placed at both ends of the cable to prevent signal reflection and ensure signal integrity. This configuration was commonly utilized in early Ethernet networks.
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.
