Pa kompyuta kapena laputopu ya pakompyuta yomwe ili ndi chotulutsira, Mtundu C ndi cholumikizira chokha, ngati chipolopolo, chomwe ntchito yake imadalira ma protocol omwe amathandizidwa mkati. Ma interface ena a Mtundu C amatha kungochaja, ena amatha kungotumiza deta, ndipo ena amatha kutha kuyatsa, kutumiza deta, ndi kutulutsa chizindikiro cha kanema nthawi imodzi. Pa chiwonetsero chomwe chili kumapeto kwa chotulutsira, chimodzimodzi ndi kukhala ndi mawonekedwe a Mtundu C, zomwe sizofanana ndi kukhala ndi ntchito zosiyanasiyana. Komabe, ma monitor onse omwe amagwiritsa ntchito mawonekedwe a Mtundu C ngati malo ogulitsa amatha kuthandizira kulowetsa chizindikiro cha kanema ndikubwezanso.
