Čo je to interný web?
In general a web might be defined as an unstructured client/server network that uses HTTP (HyperText Transfer Protocol - je určený na distribúciu hypertextových dokumentov) as its transaction protocol. The World Wide Web comprises all HTTP nodes on the public Internet. An internal web comprises all HTTP nodes on a private network, such as a corporate LAN or WAN. Note that internal webs, a.k.a intranets, are only logically "internal" to an organization. Physically they can span the globe, as long as access is limited to a defined commun ity of interest.

Ako rozsiahly môže byť Intranet
As a big as a community of interest. Scale is an important factor in web implementation, but it has no bearing on the logical association of clients that make up an intranet. For example, a workgroup with one web server, a company with several hundred web servers, and a professional organization with ten thousand web servers can each be considered an intranet.

While nothing constrains these webs to be "inside" or bounded in any physical sense, size is a significant from a network design perspective. Intranet Design Magazine calls expansive private webs wide-area intranets to connote that WAN economics and technologies apply. We call smaller, in-house webs local-area intranets.

Ako súvisí intranet s E-mailom?
It's a marriage made in CyberHeaven. E-mail is networking's killer app and the foundation of Internet messaging. Intranets inherit SImple Mail Transport Protocol (SMTP, RFC-822) from the TCP/IP suite. On top of SMTP, which enables plain text messaging, intranets use Multipurpose Internet Mail Extensions (MIME, RFC-1521) to carry diverse content. In fact, the MIME content types are the Web's content types; adding a new format such as streaming audio amounts to defining a new MIME type. All of which is to say that intranets threaten proprietary mail protocols in much the same way they threaten proprietary networking in general.

Ako súvisí s client/server systémom?
Browser = Client. Web server = Server. CGI, proprietary server API, or Java servlet = Middleware. Ako môže Intranet šetriť čas
Most organizations are run by people working together. How do your employees communicate ? by phone, voice mail, email, fax or by person to person meetings ?

An Intranet can cut down the time your employees spend on routine communication tasks. If you are using email internally you already know the benefits over trying to get someone over the phone. The one problem with using email is that the entire message is usually not conveyed in the first communication.
