[TuT]Basics of Networking

How haven't i seen this before, did it get moved from some where?

Nice thread! I am sure it will help some people out : )
The types of connections are not 'Ethernet' and 'WLAN.' There are 'wired' and 'wireless' connections, but WiFi connections are still a type of Ethernet connection. I believe there is some other information that is incorrect, but I'll have to look over it later.

Everyone on these forums should read this and learn it.

When you know these basic principals and how networks work then anyone with a decent level of logic can figure most problems they run into. EG If everyone in the RATs section read this thread there would be a ton less "help no connections/port problem/what's a host" etc.. list goes on forever.

Simple but a good read thanks.
This is thread that everybody who join hackforums should visit.I have a book with informat. terms , and explanation of every of them.That is the first thing I've learned before I started programming.New users should be suggested to visit this thread.Great job Xin R.

Great tutorial OP, bookmarked. Gonna have a good read tomorrow.
Thank you too much, really helped me.
Oh lord. Okay, I am sorry if I come off sounding like an asshole, but only a small amount if this information is actually correct. There are incorrect statements everywhere.

I have a few years taking classes in networking as well as a CCENT certification (currently working on CCNA). I'd be glad to talk over Skype and straighten this stuff out because a lot of it is plain wrong.

Firstly, "UDP networks" don't exist. Nor do TCP Networks. They are 2 transport protocols. There are more like SCTP and RDP (reliable datagrap protocol, not Remote Desktop).

Secondly, I don't think you actually know what WAN/LAN/MAN means. Yes, you got the acronyms right, but the way they connect us different.

Thirdly, you clearly have no concept of IP subnetting because your definition of IPv4 address space is completely incorrect. You never mentioned that subnet masks are what determine how many device can be in a network, the network and broadcast addresses, and which devices can talk to which other devices.

Fourth(ly?), your use of the word 'bandwidth' doesn't make sense when describing IPv6. Considering IPv6 packets are considerably larger than IPv4, they wouldn't reduce bandwidth. They do, like you said, allow for many MANY more IP addresses.

Fifth, hexadecimal goes from A to F and IPv6 networks do allow F's in their addresses.

IPv4 is four octets of 8 bits each which mean they can go from 2^0 (1) to 2^8(255). But again, subnet masks have everything to do with network space. IPv6 is 128 bits rather than 32. IPv4 has 2^32 possible combinations (about 4 billion) and IPv6 has 2^128 (32 undecilluon).

Anyways, there are a huge amount of errors in this. It's great that you're getting people interested, but its full of incorrect data.
