    INTERNET:-
     INTERNET:-
     The Internet is a vast network that
    connects computers all over the world.
    Through the Internet, people can share
    information and communicate from
    anywhere with an Internet connection.
    INTERNET:- Contd….
     Definition:
     A worldwide system of computer
    networks -- a network of networks in
    which users can get information from any
    other computer.
    INTERNET:- Contd….
     Features of Internet:

    Accessibility. An Internet is a global


    service and accessible to all, Easy to Use.
    Interaction with Other Media., Low Cost.,
    Extension of Existing IT Technology.
    Flexibility of Communication. ,Security.
    INTERNET:- Contd….
     Components to the Internet:
     There are three components to the

    Internet:
     e-mail, Usenet newsgroups, and the

    World-Wide Web.
    INTERNET:- Contd….
     How it works?
     Hardware and Software Infrastructure that

    provides Connectivity between Computers.


    Simply, the "Internet is a network of
    networks", where two or more than two
    computers are connected through a wired
    or wireless network for sending and receiving
    data - such as text, video, songs, etc.
    TYPES OF INTERNET:

     TYPES OF INTERNET:
     LAN, MAN, and WAN
     Network allows computers to connect and

    communicate with different computers via any


    medium. LAN, MAN, and WAN are designed to
    operate over the area they cover. There are
    some similarities and dissimilarities between
    them. One of the major differences is the
    geographical area they cover
    TYPES OF INTERNET:
    Other Types of Computer Networks
     PAN (Personal Area Network)
     SAN (Storage Area Network)
     EPN (Enterprise Private Network)
     VPN (Virtual Private Network, Wi-Fi,

    Broadband., DSL.
    TYPES OF INTERNET:
     LAN covers the smallest area;

     MAN covers an area larger than LAN

     WAN comprises the largest of all.


    LAN:
     Data transmits at a very fast rate
    [computers linked is limited]
     Inexpensive hardware (Such as hubs, network

    adapters & Ethernet cables). LANs cover a


    smaller geographical area (Size is limited to a
    few kilometers) & privately owned. Use for an
    office building, home, hospital, schools,
     Easy to design and maintain
    MAN
     Metropolitan Area Network (MAN) –
     Covers a larger area than that of a LAN
     Smaller area as compared to WAN.
     Connects two or more computers that are apart

    but reside in the same or different cities


     May serve as an ISP (Internet Service Provider
     Devices used for transmission of data through

    MAN are Modem and Wire/Cable.


    WAN
     Wide Area Network (WAN) –
     A computer network that extends over a large

    geographical area,
     Connecting to other LANs via telephone lines &

    radio waves & limited to an enterprise (a


    corporation or an organization) or accessible to
    the public. The technology is high speed and
    relatively expensive.
    Types of WAN
     Two types of WAN:
     Switched WAN & Point-to-Point WAN.
     WAN is difficult to design and maintain.
     A Communication medium used for WAN is PSTN or
    Satellite Link.
     WAN’s data rate is slow about a 10th LAN’s speed since
    it involves increased distance & increased number of
    servers and terminals etc. Speeds of WAN ranges from a
    few kilobits/second (Kbps) to megabits/second (Mbps).
    Propagation delay is problems. Devices used for the
    transmission of data through WAN are Optic wires,
    Microwaves, & Satellites
    Advantages
     Advantages of LAN over MAN and WAN
     LAN’s provide excellent reliability, high data

    transmission rate, manage easily, shares


    peripheral devices. Local Area Network cannot
    cover cities or towns and for that Metropolitan
    Area Network is needed, which can connect a
    city or a group of cities together. for connecting
    a Country or a group of Countries one requires a
    Wide Area Network.
