There are 100 routers connected in series like: R0 - R1 - R2 - ..... - R98 - R99. R53 gets the following ping reply when pinging the router Rx. It's also given that the routers use a system where the max TTL value is set to 164: Request timed out. Reply from 12.20.190.4: bytes=32 time=18ms TTL=116 Reply from 12.20.190.4: bytes=32 time=18ms TTL=116 Request timed out. Find the value of x. If you think the ping failed, write "-1" in the answer.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
