Difference Between Intranet and Extranet

Intranet refers to a collection of networkswithin a logical body, such as a building,corporation or other entity. Intranet canbe as simple as two computers

connected at home to each other, or asvast as 1000 branch offices of a bank,connected via privately owned, non-public network links. Intranets usuallyhave a firewall and router, which permitsaccess to the public Internet, whileprotecting the internal Intranet frommalicious users

An extranetis a private network that uses

Internet protocols, networkconnectivity. Anextranet can be viewed as part of acompany's intranetthat is extended to usersoutside the company, usually via theInternet. It has also been described as a

"state of mind" in which the Internet isperceived as a way to do business with aselected set of other companies (business-to-business, B2B), in isolation from all otherInternet users. In contrast, business-to-consumer (B2C) models involve knownservers of one or more companies,communicating with previously unknownconsumer users.

Difference Public, Private Networks and

Leased Line

public network- consists of two services. It is important tounderstand the concept of switched and dedicated servicessince mistakes in configuring telephone networks could resultin extra expense, insufficient capacity and increasedmaintenance.

private network- is a network that uses private IP addressspace, following the standards set by RFC 1918and RFC 4193.These addresses are commonly used for home, office, andenterprise local area networks (LANs), when globally routableaddresses are not mandatory, or are not available for theintended network applications. PrivateIP address spaces wereoriginally defined in an effort to delay IPv4 address exhaustion,

but they are also a feature of the next generation InternetProtocol, IPv6.

A leased line is a service contract between a provider and acustomer, whereby the provider agrees to deliver a symmetrictelecommunications line connecting two locations in exchange

for a monthly rent (hence the term lease).

SMPT VS. POP

Simple Mail Transfer Protocol (SMTP) is an Internet standardforelectronic mail(e-mail) transmission across Internet Protocol(IP) networks. SMTP was first defined in RFC 821(STD15)(1982),[and last updated by RFC 5321(2008) which includesthe extended SMTP(ESMTP) additions, and is the protocol inwidespread use today. SMTPis specified for outgoing mail

transport and uses TCPport25.

Post Office Protocol (POP) is an application-layerInternetstandardprotocolused by local e-mail clientsto retrieve e-mailfrom a remote serverover a TCP/IPconnection. POP and IMAP

(Internet Message Access Protocol) are the two most prevalentInternet standard protocols for e-mail retrieval. Virtually allmodern e-mail clients and servers support both. The POPprotocol has been developed through several versions, withversion 3 (POP3) being the current standard. POP3 is used formost webmailservices such as G-mail and Yahoo.

HTML VS. XML

The most important difference between the two markup languagesis that HyperText Markup Language, or HTML, is an applicationof SGML (Standard Generalized Markup Language),and allowsan author to omit certain tags and use attribute minimization.The Extensible HyperText Markup Language, or XHTML, is an

application of XML (Extensible Markup Language). It doesntpermit the omission of any tags or the use of attributeminimization. However, it provides a shorthand notation forempty elementsfor example, we could use
instead of
which HTML does not. A conforming XMLdocument must be well formed, which, among other things,

means that there must be an end tag for every start tag, andthat nested tags must be closed in the right order.When an XMLparser encounters an error relating to the documents well-formedness, it must abort, whereas an HTML parser is expectedto attempt to recover and continue.

Is this relevant to E- BUSINESS?Yes this activity is relevant to electronic

business because we must be aware on

networking system, how it works andtheir attributes. We need thisawareness or skills by the time that we

implement our business what ever it is.I thank YOU!
