zipangizo zamakono kulankhulana ndi njira kutumikira ife osati monga mkhalapakati kwa kufala kwa zambiri. Iwo amatha kupereka ndi kuthandiza ntchito za pa njira ndi zipangizo, anayamba kugwira ntchitoyo ogwira chosonyeza kusamalira luso zovuta.

Za mitundu kugwirizana zanenedwa kwambiri. Tidzakhala monga lembani iwo. Choncho, chifukwa kusintha deta , mungathe kugwiritsa ntchito wanthambo, telefoni, wailesi, phokoso dongosolo wailesi, TV, Kanema ndi aya m'manja, akamagwiritsa watsopano (3G, 4G, etc.), kompyuta yikidwa mawaya ndi kulumikiza opanda zingwe. Pankhaniyi, chifukwa cha chitukuko cha umisiri m'munda wa kulankhulana ndi kusinthitsa, khalidwe ndi mlingo pang'ono zikuchulukirachulukira. mbali yofunika kwambiri analongosola kuti uku sewero. Pa iwo ayankhidwa.

Mitundu ndi gulu la njira kulankhulana

Pamaso tikukamba za yonse ya, n'zomveka kudziwa tanthauzo lalikulu la "kulankhulana njira" lingaliro. Zimatanthauza dongosolo ongokhala sing'anga imene kafalitsidwe cha chizindikiro, ndi zipangizo luso ndiponso zipangizo zimene amapereka ndi kuthandiza kafalitsidwe wa chizindikiro cha pafupipafupi zina pa liwiro zina.

Pankhani gulu kapena kufanizitsa, tsopano njira kulankhulana akhoza kugawidwa motere:

• Ndi mtundu wa sing'anga conductive (chingwe kapena pafupipafupi wailesi).
• Ndi pafupipafupi osiyanasiyana (HF, VHF, UHF, mayikirowevu gulu, millimeter gulu, infuraredi).
• Malinga ndi mtundu mbendera (analogi kapena digito).

Ambiri mwina anamva mawu monga njira digito kulankhulana kapena njira kuwala. ndi zizindikiro zawo zimasiyanitsa kapena mapindu otani?

njira Intaneti popereka mauthenga mu mawonekedwe a malamulo bayinare, umene uli Amakhala yekha 0 ndipo 1. Ndi njira imeneyi, kunali kotheka kukwaniritsa imfa osachepera kapena chivundi cha deta mosiyana ndi njira analogi. Mwachitsanzo, pamene akulankhula pa foni ndi kambirimbiri analogi chizindikiro opaleshoni mfundo amene ali mosalekeza mu kulanda oscillations magetsi. Ndi chifukwa dongosolo analogi kuwombola uthenga atengeke kwambiri chopinga ndiponso akhoza kwambiri kusokoneza zambiri kapena kutaya deta.

Kuwala maulalo ndi osiyana ndi zinthu zina yokha, imene chingwe wapangidwa. Kuwala ulusi ntchito kupanga awo, zimathandiza kupereka mkulu bandiwifi, kapena osachepera kupotoza kuchepetsa chizindikiro ngakhale akutali kwambiri, asanazolowere kusokonezedwa. Komanso, CHIKWANGWANI mu mtengo yopanga n'chochepa kwambiri ndi opepuka chake miyeso wonse. Malinga ndi zimene mabuku ena amanena, kulemera kwa zingwe ochiritsira akhoza kukhala nthawi 10 kulemera kwa ochititsa kuwala kwa kukula ofanana. Kuwala maulalo ndi onse digito monga popereka mauthenga ofunikira.

Sitingathe kunena za njira opanda zingwe. Ena mwa iwo ife ntchito popanda kuganizira. Chitsanzo cha zimenezi kungakhale infuraredi (laser) njira. Kumatithandiza angayendetsere TV kapena chipangizo zina ndi akumidzi, amene amapereka anatsogoleredwa mtanda wa kuwala. Chifukwa limasonyeza opanda zingwe monga:

• Infuraredi kapena laser.
• Mayikirowevu Zingayambe (ntchito Satellite kapena LD).
• Free wailesi maukonde (kuthekera kwa HIV chizindikiro mu magulu angapo).
