Powerline is a product that is inherently flawed and its claims are at best misleading, it might work, it might even work reasonably well, but it’s not a substitute for conventional structured networking. Powerline adapters and a timer can be useful in some circumstances (e.g. kid with desktop PC using wi-fi into the early hours).

Cat6 and Cat7 cables will use the same types of connectors. The type of connector depends on the installation. Most of the time you will be using an RJ45 or keystone jack. For Cat6 cable which can come in shielded or unshielded versions you simply want to match up the shielding types on the cable and the connector.
Does Ethernet have a ground pin?
There is no dedicated GND in the classical Ethernet 8P8C ("RJ45") pinout.

Why are Ethernet cables limited?
These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won't carry a good network signal. These limits are one reason there are different types of Ethernet cables that are optimized to perform certain tasks in specific situations.
What are the limitations of Ethernet cable?
Limitations of Ethernet Cables. A single Ethernet cable has a maximum distance capacity, meaning the cable has an upper limit as to how long it can be before there is a signal loss (called attenuation ). This problem results because the electrical resistance of a long cable affects performance. Both ends of the cable should be close enough ...

What is twisted pair wiring?
Twisted Pair wiring is a strategy that uses a pair of wires which are twisted around each other to transmit data between two nodes. We will look at why this crucial strategy is important later on in this article, but the short version is it helps negate and minimize the effects of Crosstalk and Electromagnetic Interference (EMI).
How many pairs of wires are in 100base T4?
100BASE-T4 uses all four pairs in the bundle (all eight wires). One pair is used solely for Transmitting signals (TX). One pair is used solely for Receiving signals (RX). The remaining two pairs can be used for either RX or TX, and it’s up to both sides of the wire to negotiate which of the remaining pairs are used for what.

The Sentinelese people have apparently been around for thousands of years, and there are 50-200 of them alive according to Wikipedia. The fact that they live on an island and are hostile to outsiders seems to suggest that zero population flow or exchange of genetic information ever occurs on this island.
