ary ny sy nak cite ckit sal sc comp..slah 1 tjok yg sng nak ingt ialah network topology..network topology ny actually de bnyk..tpi dlm syllbus 3 je; bus, star n ring..

i)Bus Network Topology

bus ny cable yg connects compter n devices yg laen..data transmit in a series of a signal.. kalo 1 device je yg break, network still g leh access.. bus network ny murah sbb backbone dy tpi,,kalo backbone ny break, ta leh la nak access internet..

ii)Star Network Topology

Star topology ny lak,semua devices connect kat central device..sbb tu lah jdi star..central device tu ialah hub n switch..kalo 1 device fails, yg tu je la yg effected..tpi kalo hub o switch yg rosk, network ny ta leh nak operate..topology ny bnyk gne cable than topology yg laen...g 1,ny g mhal sbb cost hub ngan switch..

iii) Ring Network Topology

Cable dlm ring topology ny forms a closed loop ngan devices kat ring 2...ring ny gne token..device yg de token je leh anto data,device laen kne le tnggu dy smpe..network will down walopown 1 je device yg breaks..network ny lmbt sbb kne pas kat semua device..network ny leh share sme bnyk sbb token passing ny..data transmits dlam topology ny simple..
