Fiilooyin la arki karin. links Learning

Aaladaha isgaarsiinta ee casriga iyo channels noo adeegaysaan ma aha oo kaliya sida dhex-dhexaadin ah ee la isugu gudbiyo macluumaadka. Waxay awoodaan in ay bixiyaan oo lagu taageero shaqada oo ka mid ah farsamooyinka iyo qalabka, kormeer shaqo ee shaqaalaha si ay u meel fog laga maamuli technology adag yihiin.

About nooc xiriir la sheegay badan. Waxaan kaliya ku qor doonaa. Sidaas daraaddeed, Waayo, wareejinta xogta , waxaad isticmaali kartaa telegaraafka, telefoonka, raadiyaha, nidaamka codka baahinta, telefishanka, satellite iyo isgaarsiinta mobile, qaabab cusub (3G, 4G, iwm), St Paul computer iyo shabakadaha wireless. Xaaladdan oo kale, si ay horumarka tiknolojiyada berrinkii isgaarsiinta iyo Beddelashada, tayada iyo heerka yara mahad sii kordhaya. door weyn ee links play this. iyaga On laga wada hadli doono.

Noocyada iyo dirka khadaka warisgaarsiinta

Ka hor inta aan ka hadlo oo ku saabsan noocyada kala duwan ee, waxa macno si loo ogaado nuxurka "khadaka warisgaarsiinta" fikradda. Waxaa loola jeedaa nidaam oo ka kooban dhexdhexaad ah, taas oo faafinta ee signalka, oo ka mid ah qalabka farsamo iyo qalab in ay bixiyaan iyo taageero faafinta ee signal ah inta jeer gaar ah ee xawaaraha gaar ah.

Iyadoo la tixgelinayo kala soocidda ama ekaysiinta, waa hadda khadaka warisgaarsiinta ee waxa loo qaybin karaa sida soo socota:

• By nooc ka mid ah oo dhexdhexaad ah tabinta (cable ama inta jeer ee radio).
• By kala duwan inta jeer (HF, VHF, UHF, band microwave, band millimeter, infrared).
• Sida laga soo xigtay nooca signalka (analog ama digital).

Dad badan ayaa laga yaabaa maqlay marka la eego sida khadaka warisgaarsiinta ee digital ama channels indhaha. Maxay yihiin qaababka ama faa'iidooyinka soocayaa ay?

channels Digital gudbiyaan macluumaad qaab code binary, taas oo ah kooban yahay oo kaliya 0 iyo 1. Iyadoo technology this, waxaa suurto gal ahayd in la gaaro khasaaraha ugu yar ama musuqmaasuq xogta, in la barbardhigo hab analog ah. Tusaale ahaan, marka hadalka telefoonka waxa inta badan loo isticmaalaa analog signal mabda 'hawlgalka ah taas oo si joogto ah in suuqa kala iibsiga ee oscillations korontada. Waa sababta oo ah nidaamka analog macluumaad is-dhaafsiga waa mid aad u nugul in ay faragelin iyo si weyn u xumeeyaan kartaa macluumaad ama in ay lumiyaan xogta.

links indhaha ka timid waxyaabo kale laftiisa, kaas oo cable la sameeyo kala duwan. Dunta indhaha loo isticmaalo in ay soo saaridda, u ogolaanaya in ay bixiyaan bandwidth sare, ama dhalanrog ugu yar hoos u signal xataa masaafo weyn, difaac in faragelin. Intaa waxaa dheer, fiber ee kharashka wax soo saarka ayaa aad uga yar iyo fududee in ay dhinacyada guud. Sida laga soo xigtay ilo qaar ka mid ah, miisaanka fiilooyinka caadiga ah waxay noqon kartaa 10 jeer miisaanka kirishbooyada indhaha of size la mid ah. links indhaha labadaba waa digital sida macluumaadka gudbiyo foomkan.

Waxaan ma dhihi karo oo ku saabsan channel ee wireless. Qaar ka mid ah aan u isticmaalno oo aan xitaa ka fikiraynin ku saabsan. Tusaale ahaan of this waxaa laga yaabaa in infrared (laser) channel ah. Waxaa noo ogolaadaa in si ay u maareeyaan TV ama qalabka kale ee la fog ah, taas oo ku siinayaa dogob si toos ah iftiinka. Waayo, links wireless ka mid ah:

• Infrared ama laser.
• quudintooda microwave (isticmaalo satellite ama LD).
• network radio Free (suurtagalnimada la isugu gudbiyo signal dhowr guutooyin).
