Pele re kenella mofuteng oa OSI, re hloka ho utloisisa mantsoe a mang a mantlha a marang-rang ho tsamaisa puisano e latelang.
Nodes
Node ke sesebelisoa leha e le sefe sa elektroniki se hoketsoeng marang-rang, joalo ka komporo, printa, router, joalo-joalo. Li-node li ka hokelana ho theha marang-rang.
Sehokelo
Khokahano ke khokahanyo ea 'mele kapa e utloahalang e hokahanyang li-node ho marang-rang, e ka' nang ea ba le terata (joaloka Ethernet) kapa wireless (joaloka WiFi) 'me e ka ba point-to-point kapa multipoint.
Protocol
Protocol ke molao oa li-node tse peli marang-rang ho fapanyetsana data. Melao ena e hlalosa syntax, semantics, le khokahano ea phetiso ea data.
Marang-rang
Marang-rang a bua ka pokello ea lisebelisoa, joalo ka likhomphutha, liprinta, tse etselitsoeng ho arolelana data.
Topology
Topology e hlalosa kamoo li-node le li-link li hlophisitsoeng kateng marang-rang 'me ke karolo ea bohlokoa ea sebopeho sa marang-rang.
Mohlala oa OSI ke eng?
Mohlala oa OSI (Open Systems Interconnection) o hlalosoa ke Mokhatlo oa Machaba oa Boemo (ISO) mme o arola marang-rang a lik'homphieutha ka mekhahlelo e supileng ho thusa puisano pakeng tsa mekhoa e fapaneng.

TCP / IP ea mohlala le phapang ea mohlala oa OSI
Le hoja mohlala oa OSI e le mokhoa oa theory oa puisano oa marang-rang, mohlala oa TCP / IP ke mokhoa o sebelisoang haholo oa marang-rang. Mohlala oa TCP / IP o sebelisa sebopeho sa hierarchical, empa se na le mekhahlelo e mene feela (lera la kopo, lera la lipalangoang, lera la marang-rang, le lera la lihokelo), tse lumellanang ka tsela e latelang:
Lera la kopo la OSI <-> TCP/IP lera la kopo
Lera la lipalangoang la OSI <--> TCP/IP lera la lipalangoang
OSI network layer <--> TCP/IP network layer
Lera la khokahano ea data ea OSI le lera la 'mele <-> TCP/IP lera la sehokelo
Kahoo, mohlala oa OSI oa lihlopha tse supileng o fana ka tataiso ea bohlokoa bakeng sa ho sebelisana ha lisebelisoa tsa marang-rang le litsamaiso ka ho arola ka ho hlaka likarolo tsohle tsa puisano ea marang-rang. Ho utloisisa mohlala ona ha ho thuse feela batsamaisi ba marang-rang ho rarolla mathata, empa hape ho rala motheo oa thuto le lipatlisiso tse tebileng tsa theknoloji ea marang-rang. Ke tšepa hore ka kenyelletso ena, u ka utloisisa le ho sebelisa mohlala oa OSI ka botebo.
