Essay On Internet Intranet And Server Requirements

A report about Internet/intranet and server requirements

The internet server

An Internet server delivers WebPages to computers via a telephone or broadband connection called a dial up connection. This can be done to computers anywhere in the world as long as they are connected to the internet. An internet server has something called DNS enabling. This allows a website to be found from that websites own server e.g. when someone types www.microsoft.com, the website is associated to

Microsoft server so the website is delivered to your computer screen.

The Intranet Server

The intranet server is similar to the internet server as it delivers

WebPages to computers however it is for LAN (local area networks).

This means the pages are private

Intranets are local so other computers outside the Local area network

(LAN) cannot connect to the network.

Ways of connected to the internet

1. Dial up modem-mainly used at home, works by dialing a telephone number of an internet server and connects via that. Standard connection is 56kb. This means it sends 56,000 bits per second.

2. LAN-Delivers the internet to a network of computers via a proxy server. The proxy server connects to the internet and delivers the internet to all the connected computers in a local area network.

3. ISDN (integrated services digital network)-a telephone connection that is designed to deliver digital information for computers but also can deliver audio signals for telephone conversations. It is generally faster than standard modem connections, usually 64kb or 128kb per second. 4. Broadband-Digital telephone connection that is constantly connected, delivering data much quicker than other connections at speeds 10, 20 or even 50 times quicker than your standard 56kb connection. Instead of using a modem it uses a router allowing a permanent connection.
