diffrence between intranets and extranets?
830048
Essentially, an extranet is just an extension of an intranet.\n\nAn extranet is a private network that uses the Internet protocol and the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers, or other businesses. An extranet can be viewed as part of a company's intranet that is extended to users outside the company. Think of an extranet as being a private portion of the Internet. If you were to remove the secure aspects of an extranet then you would in effect have just another piece of the Internet.

A LAN is a Local Area Network. Local is generally referred to a network contained within a building or an office or a campus. \n\nExamples:\n(1) You might have a LAN for example on a University campus or between office blocks in an office park. \n\n(2) A big corporate perhaps like Anglo American, would generally have a LAN that might span several buildings. \n\nTo set up a LAN -relatively speaking- is cheap. If you want to put an extra couple of network points or an extra couple of devices on the network, it 's not very expensive to do that.\n\nA WAN is a Wide Area Network is a network that connects campuses.\n1. A WAN is generally slow. If we compare that to a LAN, we said that Ethernet could run up to 1000 Mbs, currently, certainly in South Africa, the fastest WAN is 155 Mbs, so you can see in a LAN we can talk up to 1000 Mbs whereas in a WAN, at the moment, currently, today in South Africa, we can only take, literally a 10th of the speed. \n\n2. WAN's are expensive. If we look at the path of telecommunications, we need to connect two offices, one in Pretoria and one in Johannesburg together - it 's an expensive operation even for a slow line. \n\nOne of the differences between a WAN (Wide Area Network) and a LAN (Local Area Network) is the set-up cost. WAN generally are to connect remote offices and when we talk about remote offices we generally refer to the remote offices as those that are outside the campus. For example, if we have an office in Pretoria and we have an office in Cape Town, these are remote offices. There is no chance that we can connect the LAN between Cape Town and Pretoria. In a LAN we connect local offices whereas in a WAN we can connect remote offices. \n\nIf you want  a detailed  discription, let me know\nvijay_v_shekhar@yahoo.com

That is a question which requires a hugh amount of time to answer.  You'd do better to just start searching the web for information on networking.  Also, "network" is something of an ambiguous term. Are you referring implementations of OSI?

Better for what?\n\nLinux is more secure but a damn sight harder to use.\n\nWindows is a virus magnet but is easy to use and is the defacto standard OS.\n\nDepends on what you want from your OS.\n\n///

No difference ,they are all used for dynamic allocation.only syntax difference i guess.

I typed in what ou asked on google and it is good.\n\nMany people use the terms Internet and World Wide Web (a.k.a. the Web) interchangeably, but in fact the two terms are not synonymous. The Internet and the Web are two separate but related things. \nThe Internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet. Information that travels over the Internet does so via a variety of languages known as protocols. \n\nThe World Wide Web, or simply Web, is a way of accessing information over the medium of the Internet. It is an information-sharing model that is built on top of the Internet. The Web uses the HTTP protocol, only one of the languages spoken over the Internet, to transmit data. Web services, which use HTTP to allow applications to communicate in order to exchange business logic, use the the Web to share information. The Web also utilizes browsers, such as Internet Explorer or Netscape, to access Web documents called Web pages that are linked to each other via hyperlinks. Web documents also contain graphics, sounds, text and video. \n\nThe Web is just one of the ways that information can be disseminated over the Internet. The Internet, not the Web, is also used for e-mail, which relies on SMTP, Usenet news groups, instant messaging and FTP. So the Web is just a portion of the Internet, albeit a large portion, but the two terms are not synonymous and should not be confused.

Internet is the whole network of computers that are connected to each other. \nOnline is when you are connected to the internet, or a website that is connected to the internet.

Both are good but apply to different situations. Off-site backup is in general more expensive and requires high bandwith between the backup server and the network to be backed-up. As a plus offers disaster recovery in almost any case available. Lets say your computers are in a building that gets on fire. An offsite back-up will recover the data no matter what.

computers networks are LAN.internet is WAN.\ninternet have a lot of computers inside,that each one has its own configuration,OS,protocols.\ncomputer networks have computers with defined configuration,OS and protocols.\ncomputer networks are alwayes available but internet(mostly) is not available without calling a link(dialup-ADSL-...)\ncomputer network is often use for file sharing and printer sharing and email.but internet is a huge source of every knowledge (it is accessed by internet browsers)

Some ethernet cards have 2 ports: one for internet, and the other for INTRAnet.  This will save you from buying a Router.

A VLAN is a type of network which allows you to have multiple devices on seperate networks and bring them together as if they were on the same network.\n\nA WLAN is a wireless network.

do u mean looking for files within the intranet? juz develop a program or search for an existing one.

LAN = Local Area Network - Usually used in a single office\nWAN = Wide Area Netowrk - Multiple locations share the same netork with the use of T1's hubs and routers.\n\nThey are pretty much the same.

The biggest differences are going to be the size of you database and your security.  Businesses are going to need dedicated storage area and firewalls and/or proxy servers.  Home networks can do most of this through software instead of hardware.

Incoming, would be..(mail.yourisp.com) and outgoing would be(outgoing.yourisp.com) Some isp's will be like this\n(incoming.yourisp.com) and outgoing would be\n(smtp.yourisp.com)..I hope this helps..Good Luck..
