A report about Internet/intranet and emcee requirementsThe meshwork serverAn Internet server delivers WebPages to computers via a telephone orbroadband connection called a dial up connection. This can be done tocomputers anywhere in the world as huge as they ar connected to theinternet. An internet server has something called DNS enabling. Thisallows a website to be found from that websites own server e.g. whensomeone types www.microsoft.com, the website is associated toMicrosoft server so the website is delivered to your computer screen.The Intranet emcee The intranet server is similar to the internet server as it deliversWebPages to computers however it is for LAN (local area networks).This means the pages are private and run through localised cabling.The WebPages are not available to computers outside the LAN and dialup connections are not enabled.Organisation the internet and intranetInternets are organised by numerous internet servers connected througha permanent broadband connection. For protection the servers areprotected from other computers putting viruses and harmful materialsby firewalls.Intranets are local so other computers outside the Local area network(LAN) cannot connect to the network.Ways of connected to the internet1. Dial up modem-mainly used at home, works by dialing a telephonenumber of an internet server and connects via that. Standardconnection is 56kb. This means it sends 56,000 bits per second.2. LAN-Delivers the internet to a network of computers via a proxyserver. The proxy server connects to the internet and delivers theinternet to all the connected computers in a local area network.3. ISDN (integrated services digital network)-a telephone connectionthat is designed to deliver digital information for computers but alsocan deliver audio signals for telephone conversations. It is generallyfaster than standard modem connections, usually 64kb or 128kb persecond.4. Broadband-Digital telephone connection that is incessantlyconnected , delivering data much quicker than other connections atspeeds 10, 20 or even 50 times quicker than your standard 56kbconnection. Instead of using a modem it uses a router allowing apermanent connection.Web Server RequirementsWeb servers can be as fast or powerful as the user requires. This is restricted on what system they are running. A standard internet serverwill be 500MHZ, have 256MB of RAM and have around 8GB hard chock upspace. Of course all of these can be expanded dependent on the usersneeds. Also it depends on how many users are on the network. The moreusers, the faster the server will be required to allow a good internet
