    අපි දැන් බලමු Network Types මොනවද කියලා.

    LAN (Local Area Network)

    It is a group of network components that work within small area

    ඒ කියන්නේ යම් කිසි නිශ්චිත ස්ථානයක තියෙන පරිගණක ජාලයක් LAN එකක් විදහට ගන්න පුලුවන්



    fpdservicos-lan.gif



    උදා - අපි කියමු කොටුවේ තියෙන පිට්ටු බම්බුව(ලංකා බැංකුව) බිල්ඩින් එ‍කේ තියෙන Computers ඔක්කොම එකතු කරලා Network එකක් හැදුවොත් අන්න ඒක (ඒ බිල්ඩිම) LAN එකක් කියලා කියන්න පුලුවන්




    MAN
    (Metropolitan Area Network):

    It is a group of LANs that are interconnected within small area

    metropolitan-area-network.jpg


    උදා- ඉහත රෑපය දිහා බලන්න. අපි හිතමු යම් ආයතනයක එහි අංශ (Manufacturing, Shipping) එකම බිල්ඩින් එකේ නැතුව ටිකක් දුරින් තියෙනවා කියලා හැබැයි ඒවා තියෙන්නෙත් එකම නගරයේ. අන්න ඒ වගේ එකකට තමයි අපි කියන්නේ Metropolitan Area Network එකක් කියලා


    WAN (Wide Area Network):

    It is a group of LANs that are interconnected within large area


    wide-area-network.jpg


    උදා- හොදයි අර කලින් උදාහරණයම ගමු දැන් හිතන්න අර ආයතනයේ ශාඛා තියෙනවා කියලා වෙන නගර වල මේවා එකිනෙකට දුරින් පිහිටලා තියෙන්නේ. එතකොට ඒ සියලු නගර වල තියෙන ශාඛා එකට සම්බන්ද කරලා ගොඩ නගන පරිගණක ජාලය තමයි WAN එහෙම නැත්තම් Wide Area Network කියලා කියන්නේ.

    මොනවද මේ NETWORK TOPOLOGY

    It describes how devices are physically cabled

    ඒ කියන්නේ අපේ Network එකේ තියෙන host machine එකට සම්බන්ධ ‍වෙලා තියෙන ආකාරය තමයි Network Topology එකකින් විස්තර කෙරෙන්නේ.

    අපි
    Topology 6ක් ගැන බලමු


    1. Bus Topology
    2. Ring Topology
    3. Star Topology
    4. Extended Star Topology
    5. Hierarchical Topology
    6. Mesh Topology
    network-topology.jpg


    හොදයි අපි එකින් එක ගැන පොඩි විස්තරයක් බලමු


    Bus Topology

    Bus Topology using single backbone. all Host machine are directly connected to this backbone

    මෙහිදී එක ප්‍රධාන Line එකකට
    Network එකේ තියෙන ඔක්කොම Host සම්බන්ධ වෙලා තියෙනවා

    මේකෙ තියෙන අවාසි තමයි කොහෙන් හරි ඔය
    backbone Line එක කැඩුනොත් එතනින් එහාට Network එකේ තියෙන කිසිම Resource එකක් පාවිච්චි කරන්න බැරි වීම
    bus.gif



    Ring
    Topology

    The Ring Topology connects one host to the next and the last host to the first.

    ඒ කියන්නේ රවුමක් ‍වගේ සියලුම
    host එකට සම්බන්ධ වෙලා තියෙනවා.
    01fig04.gif

    හැබැයි මේක Bus Topology එකටත් වඩා චාටර් මොකද Bus Topology එ‍කේ යම් කිසි host කෙනෙක්ගේ Connection එක විතරක් down වුනත් backbone Line එක Ok නම් Network එක වැඩ. හැබැයි Ring Topology එකේ එක host කෙනෙක්ගේ Connection එක down වුනොත් මුලු Network එකම down වෙනවා.

    Star Topology

    A star network features a central connection point called a "hub" that may be a hub, switch or router.

    මේකෙදී සියලුම host ලා එකට සම්බන්ධ වෙන්නේ මධ්‍ය උපකරණයක් හරහා ඒකට කියන්නේ hub එකක් කියලා (මේ hub එක කියන්නේ අපි hub කියලා හදුන්වන network device එක නෙවෙයි ) මේ මධ්‍ය උපකරණය ‍නැත්තම් hub එක ලෙස Hub,switch එකක් හරි router එකක් තියෙන්න පුලුවන්

    Extended Star Topology

    An extended star topology links individual stars together by connecting the hubs and/or switches. This topology can extend the scope and coverage of the network.


    යම් network එකක් ප්‍රමාණයෙන් විශාල වෙන විට මේ extended star topology එක භාවිතා කරනවා.

    Extended_star_topology.png


    හොදට බලලා මේ Topology එකේ තියෙන දුර්වලතා හදුනා ගන්න. මම හිතනවා ඒක එච්චර අමාරැ නෑ කියලා.


    Mesh Topology

    A mesh topology is implemented to provide as much protection as possible from interruption of service.

    Each host has its own connections to all other hosts.

    මෙන්න මේ
    ක තමයි අද වඩාත්ම දක්නට ලැබෙන topology එක. මෙහි අර උඩින් විස්තර කරන ලද සියලුම topology වලට වඩා වාසියක් තියෙනවා ඒක තමයි එක connection line එකක් කැඩුනත් network එක down වෙන්නේ නෑ.
