Because - even in fibre-optic cable, distance brings attenuation of the signal. Repeaters boost the data stream to provide a constant signal level.
The distance between two repeaters can vary depending on the specific type and model of the repeaters being used. In general, repeaters are typically placed about 20-30 miles apart to effectively boost and extend the signal of a network. However, this distance can be shorter or longer depending on factors such as the environment, terrain, and frequency being used.
Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.
On a standard Ethernet network, between any two devices that communicate (such as computers), you can't have more than 4 repeaters (this includes hubs). "5-4-3" refers to a maximum of 5 segments; 4 repeaters; 3 segments with hosts on them.

Star Topology, where Hubs can act as repeaters.
Either a Bus topology or Wireless repeating, depends on how the question is stated...
Cell repeaters have functions like extension of wireless range. When two hosts are being used, they have to be connected using a MAC (Medium Access Control) and a PHY (Physical Layer) but the connection is too long and to make it easier and shorter, one have to use cell repeaters to bridge the gap.
It's a protocol that enables communication between computers and servers.
it is cable used for data transmission between computers
1.It is very expensive as according to the distance the no.of repeaters can be fixed and accordingly the budget or the expenditure will increase or decrease. 2. it takes a lot of time to set a repeaters between two stations.
Wireless networks often use repeaters to extend the network signal to distant locations. Ethernet repeaters are commonplace as well, as there are limits to the lengths that cables will function at.
