Yintoni i-IEEE 802.3?

I-IEEE 802.3 liqela elisebenzayo elabhala i-Institute of Electrical and Electronics Engineers (IEEE) isethi esemgangathweni, echaza ulawulo lokufikelela okuphakathi (MAC) kuzo zombini iileyibhile zekhonkco kunye nedatha ye-Ethernet enentambo. Oku kuqhelekile ukuba bubuchwephesha bommandla wommandla (LAN) obunosetyenziso lwenethiwekhi yendawo ebanzi (WAN). Ukuseka unxibelelwano lomzimba phakathi kweenodi kunye nezixhobo zesiseko (iihubs, iiswitshi, iirotha) ngokusebenzisa iintlobo ezahlukeneyo zobhedu okanye iintambo zokukhanya.

I-802.3 bubuchwepheshe obuxhasa i-IEEE 802.1 yoyilo lwenethiwekhi. I-802.3 ikwachaza indlela yokufikelela kwi-LAN usebenzisa i-CSMA/CD.

Yintoni i-Subnet Mask?

Imaski yesubnet ikwabizwa ngokuba sisigqubuthelo sothungelwano, imaski yedilesi, okanye imaski yenethiwekhi engaphantsi. Ibonisa ukuba yeyiphi na amasuntswana edilesi ye IP echonga subnet yomamkeli kwaye zeziphi na bits ezichonga i-bitmask yomamkeli. Imaski esezantsi ayinakho ukubakho yodwa. Kufuneka isetyenziswe ngokubambisana nedilesi ye-IP.

I-subnet mask yidilesi ye-32-bit efihla inxalenye yedilesi ye-IP ukwahlula i-ID yenethiwekhi kwi-ID yomninimzi, kwaye ibonisa ukuba idilesi ye-IP ikwi-LAN okanye i-WAN.
