Network bus topology

Network topology inowanzoshandiswa kugumiswa kwechimiro chebhazi, haitsigire network yakatenderedza kana nyeredzi. Yese node is serial yakabatana nebhazi rimwe isarudzo yakanaka, mumufananidzo uri pamusoro, iyo general network topology yeA8-05B system inoratidzwa. N node dzakabatana mune multipoint network. Kune kumhanya kwepamusoro uye mitsara yakareba, kumisa kupikisa kunodiwa pamativi ese emutsara kuti ubvise maratidziro. Shandisa 100 Ω resistors kumativi ese (inoda chete kana waya kureba> 2km). Iyo network inofanirwa kugadzirwa semutsara mumwechete une madonhwe akawanda, kwete senyeredzi. Kunyangwe hurefu hwetambo hwakazara hunogona kupfupika mukumisikidzwa kwenyeredzi, kumisa kwakakwana hakuchagoneki uye mhando yechiratidzo inogona kudzikisira zvakanyanya. Mudhayagiramu 1 iyo yairatidza inotevera, b, d, f inobatanidza zvakanaka uye a, c, e kubatanidza kusina kunaka.
