I just finished editing a script about TCP/IP protocols, ask me anything

[BigMcLargehuge]

But if you ask about TCP/IP I may have to run screaming from the room.

[WilliamPitt]

1. Drat

That's exactly what I was gonna ask.

OK...

What's your favorite color?

[BigMcLargehuge]

3. Yellow

always has been. Not that namby pamby soft yellow either. I mean like Marigold yellow. The kind of yellow that puts hair on your chest when you see it. Yellow like staring into the Sun!!!!

You know TCP/IP uses five protocol layers? AHHHHHHHHHHH!!!!!!!!!!!

[WilliamPitt]

4. I wouldn't know a TCP/IP script if I was pissing on one

I was gonna ask you what they were. I know what a script is, I think. Program to check code, right?

Me <------ not technical. English major.

[BigMcLargehuge]

8. Actually, it's a data communications protocol set

used to move data from one place to another over a specific network type. For example, you posting to DU uses all five layers of the protocol stack.

The application layer (your browser)
The transport layer (the type of program used to create/display the information, in this casr HTML and Java)
The Network Layer, what type of network your computer uses. In this case Internet Protocol (the addressing scheme to get your packet from your computer to the DU server)
The Data Link Layer, the type of error correction and flow control to maintain efficient communication between your computer and the DU server (and routers in between)
The Physical layer, the interface between your computer and the wire carrying your information into the network be it modem communications, Ethernet, 802.11 Wireless, or Fiber optic.

10. Cool

I read and understood all of that. Am I officially a geek now?

:)

[section321]

14. You're officially a geek when you can figure out your own IP address.

.

:-)

[BigMcLargehuge]

19. Well, I like to think

it means I'm a good writer as I can convey all this malarky to normal people.

But you can be a geek if you want to :)

Incidentally, I have an English and History Degree. I learned all this telecom crap on the job.

Who'd a thunk it.

[slackmaster]

2. Could your script be adapted into a feature-length movie?

And if so, who would you ask to play the leading roles?

[BigMcLargehuge]

6. My cast

Jackie Chan As The Physical Layer
Steve Jobs As The Data Link Layer
Ted Turner As The Network Layer
Bruce Dickinson As The Transport Layer
Pamela Anderson As The Application Layer

A tight action story about a team of super-protocols who ferry critical information from one end point to another!!!!!

[disgruntella]

7. sequel to "gigli"?

With Ben Affleck as SYN and J. Lo as ACK?

(Just flaunting my limited knowledge of TCP/IP... better not ask me anything)

[Kamika]

5. Just how does TCP/IP work?

and take it gently i dont know anything about computers then how to use word or chat

[section321]

13. I don't know if there is an easy way to explain it but....

TCP (Transmission Control Protocol) and IP (Internet Protocol) are standards that allow computers to communicate.

The set rules for computers to follow when they communicate. They set timing, message length, message format, naming, etc...

TCP and IP are different "layers" of the Internet Protocol suite.


If you still want to know more, here is a pretty good intro from Cisco.

[BigMcLargehuge]

15. It's pretty easy to get the gist of...

The way it works is:

Assume you're sending a post to DU's forum (like we are right now)

Your application, in this case your Browser, captures all your typed information as a series of bytes (words made up of a combination of eight 1s and/or 0s). The Application Layer contains content specific information, in this case, the actual bytes used to represent the characters and formatting of your DU post.

Those bytes are passed from the application to the Transport Layer (Layer 4), in this case the transport layer is TCP or Transmission Control Protocol. TCP adds sequence numbers to the packets generated by the browser and passes them to the Network Layer.

The Network Layer (Layer 3) adds the standard addressing information required by Internet Protocol. That address is a ten-digit number identifying your computer, and the destination computer (The DU Server). The Network Layers "encapsulates" the preceding information creating a data frame. The Network Layer passes the encapsulated packet (or frame) to the Data Link Layer.

The Data Link Layer (Layer 2) appends a header and trailer to the encapsulated packet. The information it adds is used for flow control and error correction. The Data Link Layer passes the encapsulated and appended packet to Layer 1.

The Physical Layer (Layer 1) is the interface between your computer and the network. In some cases this interface uses a modem, or an Ethernet jack, or an 802.11 wireless antenna. The Physical layer converts all that packetized information into the correct transmission format for the medium used in the interface, for example, electrical pulses for modem and Ethernet, optical pulses for optical fiber, or a modulated radio wave for 802.11.

The DU server receives this encapsulated packet from the network and reads all the information, in the opposite order until it gets to the correct application.

So:

The Physical Layer interface in the server converts the incoming pulses into bytes and passes those to Data Link Layer who checks the packets for errors then passes the encapsulated packets to the Network Layer who checks the address and determines that these packets are in the right place, who passes the remaining bits and bytes up to the Data Link Layer who sequences the information and passes it to the Application Layer who determines from the information which applicaiton needs to receive the packets.

How's that?

[section321]

9. Can I just use UDP instead?

Its so much lighter.

[section321]

11. p.s. So what does the script do? Sniffer? Remote data access?

cripple Western civilization?

[BigMcLargehuge]

16. the script teaches new telecom employees about data networks

not really exciting. Unless the new employees work in Dr. Evil's telecom wing.

[section321]

18. Sounds interesting...

Does it allow them to see what's on the network? (i.e. hosts, traffic, etc...)

How does it teach?

What did you write it with?

[BigMcLargehuge]

20. You 're thinking "script" and I'm thinking "script"

Not a programming script, an actual narrated script, like sent to a narrator and read...

It's an e-learning course.

[section321]

21. Oh. Oops.

I was looking for the wrong kind of "script."

That's cool. :toast:

[short bus president]

12. Is it Free, or free, or proprietary? n/t

[BigMcLargehuge]

17. TCP/IP is an open protocol suite

so ANYONE can develop apps that make use of the standards.

[patdem]

22. Which room will you alite in? After you go screaming from this one?

cause I see lots of TCP/IP questions...one of which I have....WHO GIVE A FU*K?

[BlueJazz]

23. I remember a few years ago when I

took the TCP/IP part of the MCSE suite.
I was new to the whole thing and I swear if I didn't know any better I'd say that
Microsoft picked the hardest tcp/ip questions in the world so I'd
fail the test and have to give them the $100.00 dollars again.
I mean EVERY question was about 10 lines long and deep.
I missed passing by 2 questions.
The next time I took it though, I only missed 1 question on the test.

[zbdent]

24. May I play Eyegore?

Or maybe Harpo, but I think that I'd flub my lines.

[BigMcLargehuge]

25. Depends... can you "google" your eyes like Marty Feldman?

Because that's mandatory.

[zbdent]

26. Nope. Sorry. How about my Yoda/Grover impression?

Or Marvin the Martian, since his neighborhood is in the neighborhood.

[BigMcLargehuge]

27. Sure, what the hey...

The world needs more Frank Oz's and Frank Oz impersenators...

No Miss Piggy's though.

[zbdent]

28. "Watch it, buster!"

"Heiiii-YAH!"

Actually, I do a few. Currently compiling a list of ones I can do somewhat, Yoda and Marvin I do pretty well.

A co-worker said that I should try for voice-over work.

Now how do you go about that? My one big-screen appearance was edited out (a feature death)! Of course, the film was only by a person who is a half-step above film student, and only played once in Cleveland.
