group19_angels:how does internet work

Internet is simply computers connected in a network.All these computers connected in a network are assigned a unique IP address provided by the server or the router.If we connect to the Internet through an Internet Service Provider (ISP), we are assigned with a temporary IP address for the duration of your dial-in session. If we connect to the Internet from a local area network (LAN) our computer might have a permanent IP address or it might obtain a temporary one from a DHCP (Dynamic Host Configuration Protocol) server.if we have to access a web page something of the kind www.google.com ,then it connects to the domain name service (DNS)server which keeps a track of all the computer names and their corresponding IP addresses.Here google also has a unique IP address and only after DNS server matches its IP address ,the accessor gets to see the web page he/she is looking for on his/her computer.If it does not find the address of the particular computer ,the request will be forwarded to another DNS server.
