Answer and Explanation:
1. There is a reasonable possibility that because of blockage in a system, the information bundle may take on various courses to reach to the goal. Presently, if the system is truly blocked, and there is no hop limit, the bundles may continue going in the system inconclusively (or an unending circle). Presently, assume another parcel is sent and that also continues circling in the system due to the blockage. At that point another, etc. Do you see the chain impact? As these parcels continue circling in the system, the clog doesn't appear to leave, yet continues expanding. Along these lines, as a method for blockage control, there is a hop limit so that on the off chance that a bundle winds up in a circle, rather than permitting it to add on to the system traffic, it's smarter to drop it.
2. Technically, the series of routers between a source and the destination may go way above 255 (in case of congestion or bad routing algorithm). But as the Internet is growing, more long-distance links are being built (or already have been built), making it possible for a packet to get from one country to another in less than a few hops, if not, then the infrastructure is not right. Though this assumption was controversial, it was accepted. The routing algorithms are able to find short paths between destination and source.
