All About Internet
what is internet ?
internet
internet. Two or more network segments connected by routers. Another
term for internetwork.
Internet. A worldwide network of computers. If you have access to the
Internet, you can retrieve information from millions of sources,
including schools, governments, businesses, and individuals.
what is world wide web ?
World Wide Web
A system for exploring the Internet by using hyperlinks. When you use a
Web browser, the Web appears as a collection of text, pictures, sounds,
and digital movies.
Internet address
An address for a resource on the Internet that is used by Web browsers
to locate Internet resources. An Internet address typically starts with
a protocol name, followed by the name of the organization that maintains
the site; the suffix identifies the kind of organization it is. For
example, the address http://www.blanjo.com/ provides the following
information:
http: This Web server uses the Hypertext Transfer Protocol.
www: This site is on the World Wide Web.
com: This is a company website.
Internet address is also called Uniform Resource Locator (URL).
Internet Control Message Protocol (ICMP)
A required maintenance protocol in the TCP/IP suite that reports errors
and allows simple connectivity. ICMP is used by the Ping tool to perform
TCP/IP troubleshooting.
Transmission Control Protocol/Internet Protocol (TCP/IP)
A set of networking protocols widely used on the Internet that provides
communications across interconnected networks of computers with diverse
hardware architectures and various operating systems. TCP/IP includes
standards for how computers communicate and conventions for connecting
networks and routing traffic.
Internet Engineering Task Force (IETF)
An open community of network designers, operators, vendors, and
researchers concerned with the evolution of Internet architecture and
the smooth operation of the Internet. Technical work is performed by
working groups organized by topic areas (such as routing, transport, and
security) and through mailing lists. Internet standards are developed in
IETF Requests for Comments (RFCs), which are a series of notes that
discuss many aspects of computing and computer communication, focusing
on networking protocols, programs, and concepts.
Internet Group Management Protocol (IGMP)
A protocol used by IP hosts to report their multicast group memberships
to any immediately neighboring multicast routers.
Internet Information Services (IIS)
Software services that support Web site creation, configuration, and
management, along with other Internet functions. Internet Information
Services include Network News Transfer Protocol (NNTP), File Transfer
Protocol (FTP), and Simple Mail Transfer Protocol (SMTP).
Internet Protocol (IP)
A routable protocol in the TCP/IP protocol suite that is responsible for
IP addressing, routing, and the fragmentation and reassembly of IP
packets.
Internet Protocol multicasting
The extension of local area network multicasting technology to a TCP/IP
network. Hosts send and receive multicast datagrams, the destination
fields of which specify IP host group addresses rather than individual
IP addresses. A host indicates that it is a member of a group by means
of the Internet Group Management Protocol (IGMP).
Internet Protocol security (IPSec)
A set of industry-standard, cryptography-based protection services and
protocols. IPSec protects all protocols in the TCP/IP protocol suite and
Internet communications using L2TP.
Internet service provider (ISP)
A company that provides individuals or companies access to the Internet
and the World Wide Web. An ISP provides a telephone number, a user name,
a password, and other connection information so users can connect their
computers to the ISP's computers. An ISP typically charges a monthly or
hourly connection fee.
Internetwork Packet Exchange (IPX)
A network protocol native to NetWare that controls addressing and
routing of packets within and between LANs. IPX does not guarantee that
a message will be complete (no lost packets).
