IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses. IPv4 can support up to 232 addresses, however the 32 bits IPv4 addresses are finishing to be used in near future, so IPv6 is developed as a replacement.
IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features. Here are some examples of IPv6 address:
1050:0:0:0:5:600:300c:326b
ff06::c3
0:0:0:0:0:0:192.1.56.10

The Difference Between Straight cable and Cross Cable
It's the difference in how a cable is wired. It's called the Pin-Out.
Ehternet uses 2 pairs of wires in a cable. 1 pair for Send the other for Recieve. On a standard RJ45 Jack, pins 1 and 2 are the Send Pair and pins 3 and 6 are the recieve...... a straight through cable is wired identically at both ends. a crossover cable switches the pairs 1 and 2 and 3 and 6...... the the wire connected to pin number 1 is connected to pin number 3 at the opposite end of the cable and the wire for pin 2 is connected to pin 6 at the other end..... it just crosses over the pairs
a crossover cable is used to connect like devices, like a router to a router, but a straight through cable is used to connect dissimilar devices, like a router to a computer.
Common Ethernet network cable are straight and crossover cable. This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called RJ45 connector.

Adsense
High quality content for your website, whether it is designed for Adsense, or as a general content site with other monetizing techniques, will not only attract visitors, but will get you good listing placements on the search engines.
Content makes your site more valuable to visitors and so more attractive to the spiders. Placing articles relevant to the theme of the page is a great way of providing this content.
There are a number of ways of finding articles, the most common being:
Write Them Yourself
This is probably the best way, if you have the time and the ability.
Hire a Writer
This is good, though it can be expensive to have someone write original articles for you, and many of those I have seen are less than perfect with regard to literacy.
Generate Them with Software
There is software available, some expensive, that can generate articles for you. I own a few different ones, and do you know what? I end up having to edit most of them to make them read right for my keywords, and there are long strings of identical text in every one. Duplicate content!
Get Them Elsewhere
You can get articles from article directories, but to avoid breaking copyright law, you have to include the writer's 'resource Box' which contains his website URL. This gives the writer a link back to his site from your's. Not only that, but how many others are doing the same? How many more websites is this article on. Are you putting duplicate content on your site?
