Well, its says at the top about MP4 - was that a mistake? Or is there something called MP4? And if so, what is it?!

MPEG6 now exists that allows you to use XML data with video and I am not sure about audio, some researchers have been able to make security systems out of this feature. That if a person moves an object out of a designated zone then a piece of software would fire up an alarm. Something I have a bash at doing on my own at University as part of a piece of research into MPEG6, though I have to say have not seen it being used allot.

If anyone's curious and not said this before MPEG (MPx is just an abbreviation of the initials) stands for: Moving Picture Experts Group.

Also I just thought it might be fun to extend what some other have used:

WAN and LAN are both typical forms of switching networks, when I was at Further Education college we would do networking on our own we would get a very old serial com port cable and connect 2 computers up. That's great for 1 to 1 connections but when you get more than those 2 computers this scenario shall we say will most definately become problematic. So you need another node in the middle to direct traffic between computers called a router (why their so common place now even in homes).

If we back track back to the serial port example if one computer was to send out a message to what the user presumes to be 1 computer without knowing how the network behaves would accidentally send out all that data their sending to all the nodes on the network since there's no router to decide where that data was to go to.

Proxy server - A server that caches web pages for fast retrievel. only queries updates for a web page if it is in its cache rather than the whole page.

Being the type of person that hates to have to correct someone, a Proxy is not always a caching server at all, hence why are there literally 1,000s of anonymous proxy HTTP servers around on the web that don't cache your surfing results.

A proxy is just a computer you use between your connection and your site to hide your real identity, that's all a Proxy is, if you send a proxy voter to go and vote, means you arrange in say either a local or general election someone you trust to vote for you, trusting them to vote for the person you requested the proxy to vote for.

That's the definition of a Proxy it has nothing to do with caching at all, caching is just another feature that can be put onto a Proxy connection, some have caching some don't.

Though to really hide your true identity a Proxy must be on someone elses network, not on your own local area network, or all packets going out of your network will have your own IP address stamped to them in the header, so not really hiding your identity at all!

To add formal weight to this (though using somewhat sometimes unreliable wiki, since there's been 100's of errors I have seen, but for acronyms tends to be ok, just not for other things I look for):

"In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control their complexity. Today, most proxies are web proxies, facilitating access to content on the World Wide Web."

Logically it would be pointless in having a caching proxy on a VPN of another network somewhere half across the world, would actually turn out to be a whole lot slower than a proxy VPN server that sends you responses directly, in aid it would be fun to set something like that, albeit pointless if you wanted a faster response rate, to me not worth doing at all.

MAN Metropolitan Area Network, commonly used at Universities that have multiple sites, not usually seen anywhere else but there are a few other companies that use them, it's like of like you have say a University wide network one campus on one side of a city in a geographical location and another at the other end of the city, and you join them together (suppose somewhat like a VPN could be a MAN) it's like half way between a LAN and a WAN

VPN Virtual Private Network allowing 2 [or more] networks that are both connected to the Internet but then use the Internet as a method for connecting the 2 together, sometimes across several cities or even country's, you could say that's the Internet anyways, but hence it being called 'Private' meaning one must have an authentication in place to get into that particular network, like a set of Virtual Network Adapters (like Comodo's TrustConnect installs a Virtual Network Adapter to get onto its VPN, when you go for their complete security), that network card (not physically in or on your computer. it's fabricated by software, and it's what's used to access their network, without it, you won't be able to use Comodo's VPN), used like a caching server to some times hide your true identity on the Internet at large.

Token Ring it's a kind of extension to a network [or is a] topology. usally used when you have coaxial cable networks, the Blueyonder; then Cable and Wireless, then NTL Home (I think was it's end company name or something probably t/a whatever) and finally now Virgin Media, has it's network setup.

Allows for little (though never seen a diagram of how the actual networks structured, so I can't vouch for it definitely is this topology but would make sense to some of its drawbacks), each little regional zone (or ring) has it's own central server, or probably some kind of router/switch, then each one of those rings has a central point say usually in the local exchange that's part of a much bigger network. Usually using a coaxial cable to connect up the nodes (modems, or as their calling them at the moment the superhubs, which are manufactured by Cisco at the present moment, although that's on mine which is 60mb now).

Teamviewer

This software is IDEAL if you are having issues, but know someone who can fix your PC... except they cannot get to you

This software allows another person to virtually control your machine - and it is totally free.

teamviewer.com/en/index.aspx

Download & set up in about 5 minutes... I helped a friend install all their drivers after they reinstalled windows. They live in Ireland, and I'm in the UK

Last time I used teamviewer was when I was setting up someones Domain Name Service server for live querying. For which I was being paid for as well. They where from CA in America too.

In that case anyone remember using a humble tape recorder to load software on to your shiny new pc before floppy drives came onto the market? Or having to type everything into a command line before a gui was part of the os? (I prefer command line)

The tape drives were still around after floppies appeared. My first computer was a Vic-20 with a tape drive.

I remember the fun of typing the code for games in from magazines

Also includes black-hat methods such as spamming forums with links in order to improve your positions in the search engines.

It would appear that the OP already knows about this aspect of it though judging by their spammy link to an SEO website.

Ah yes, search engine optimization, a crucial skill for any web developer.

Backlinks, keywords, meta tags, panda & penguin, pagerank.

Essentially it's getting your site to the top of google search results for particular terms.
