1999 Asian Women's Network Training Workshop 11 Internet Protocol (IP) lower layer method or set of rules by which data is sent from one computer to another on the Internet. handles the address part of each packet so that it gets to the right destination.

1999 Asian Women's Network Training Workshop 12 IP address

1999 Asian Women's Network Training Workshop 13 IP-address example: Unique scarce 4 octets (8-bit-bytes) value of each octet classes of networks (A,B,C, CIDR)

1999 Asian Women's Network Training Workshop 14 Each computer (known as a host) on the Internet has at least one address that uniquely identifies it from all other computers on the Internet. When you send or receive data (for example, an note or a Web page), the message gets divided into little chunks called packets.

1999 Asian Women's Network Training Workshop 19 Domain Name System The domain name system (DNS) is the way that Internet domain names are located and translated into IP (Internet Protocol) addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address. Because maintaining a central list of domain name/IP address correspondences would be impractical, the lists of domain names and IP addresses are distributed throughout the Internet in a hierarchy of authority.

1999 Asian Women's Network Training Workshop 20 Domain Name a domain name locates an organization or other entity on the Internet. Example: kuanyin.isiswomen.org kuanyin = host server.org = the part of the domain name that reflects the purpose of the organization or entity, also known as top level domain name isiswomen = part of the domain name defines the organization or entity and together with the top-level is called the second-level domain name.
