topology kya hai ? aur yeh kaise kam karta hai ?

Topology kya hai?

yeh network mein nods kay interconnection kaa pattern hai jise topology kaha jata hai

Network topologies

Ek network computer karane kay liye kuch layout mein jude honey key jarurat hai jise topologies kay roop mein jana jata hai
yeh algaon mein network kay liye ek topology kay chayan kay roop mein nahin kia jaa sakata hai kyonki yeh media key pasand aur upayog vidhi ko prabhavit karta hai

vikalp ko sabse mahatvapoorn banane mein kai karakon par vichar kia jana hai jinmen sey nichey set kie gaye hain:-

1-COST-network ko lagat prabhavi banane kay liye sthapana lagat ko come karane kaa prayas karen, ise achchi tarah sey samjhe jane vale media kaa upayog krake aur isamen shamil duri ko come krake bhi come had tak prapt kia jaa sakata hai

2- RELIABILITY– network mein viphalata aur sabse pahle banane kay liye ley aur vyaktigata node kharabi kr sakte hann
yeh lagabhag jangal kay doosare prakar kay roop mein ek gambhir kay roop mein nahin hai, jahan network hee kam karane kay liye kehte hain । network kay liye chune gaye topologies aur giravat kay sthan kaa pata lagane kay liye aur ise alag karane kay sadhan pradan karane key anumati dekar madad key ।

Point to point link-

phankshan sancharit aur prapt karane kay liye point link key baat karen, pee-pee network key mukhya visheshata yeh hai ki pratyek station ek transmitar sey bilkul prapt hota hai aur pratyek transmitar sancharit karta hai bilkul ek receiver key avashyakata hoti hai sancharit aur prapt apareshan behtar pradarshan kay liye alag taron par key peshkash kr sakte hain yaa ve takanikon key ek kism kaa upayog kr ek hee taar par bari ley jaa sakte hann
pvaint too point network ek vidhi bus network mein pee-pee link computer sthapit karna hai is drishtikon ko gadbad kaha jata hai

1-The star topology

2-the bus

3- the ring or circular.

4- the tree.

5-The graph.

6- the mesh

1- Star topology kya hai?

IS  topology mein sentral node hota hai jisake liye anya sabhi nods ekal path sey jude hote hann yeh data processing yaa voice communication sey jude sabse maujooda soochana network mein istemal key jane vali takanik hai iska sabse aam udaharan 10 bes tee-ethernet installation hai । yeh network upakaranon sey jude 10 adharit kebal key mud jodi kay madhyam sey hai ।

Types of advantages are:

Ease a service advantage- star topology mein kai ekagrata bindu hain jahan kanekshan shamil hote hain ve network key seva yaa punarvinyas kay liye asan pahunch pradan karte hann

One device per connection – kissi bhi network mein kanekshan ank svabhavik roop sey viphalata kay liye prne hann ek kanekshan key indie star topology viphalata mein amataur par kissi bhi anyatha puri tarah sey karyatmak network sey ek node ko disconnect karna shamil hai

Centralised control / problem diagnosis- yeh tathya yeh hai ki kendriya node sidhe network mein hara doosare node sey juda hua hai iska matlab hai ki phols ko asani sey pata lagaya jata hai aur ise alag kia jata hai ki system sey ek sadharan disconnect asaphal nodes

Simple access protocol- star network mein die gaye kissi bhi kanekshan mein keval kendriya nods shamil hann is sthiti mein joe pareshan uddeshya kay liye madhyam kaa niyantran hai kay liye vivad asani sey hala ho jata hai । is prakar network kaa upayog protocol bahut saral hai

Disadvantages

Long cable length- ljaisa ki pratyek node sidhe kendra sey juda hua hai star topology yeh ek kebal key ek badi matra hai jabaki kebal duct mein penn small kanjeshan key lagat aur rakharkhav aur sthapana samasyaon mein kafi vriddhi ho sakti haie addition of a new node to Star network in was a connection all the way to the central nodes.

Central node dependency- yadi ek star network mein kendriya node viphal rehta hai poore network ek portable mein gaaya jata hai yeh node par bhari vishvasaniyata aur atirek badhaon kaa parichay

The bus or linear topology – data network kay liye ek aur lokapriya topology raikhik proudyogiki hai
isamen transmission madhyam key ek lambai hoti hai samanya roop sey anya vibhinn nods kay saath do par koksiyal kebal sanlagn hoti hai topology kaa upayog parampric data sanchar network mein kia jata hai jahan mejaban ek chhor par hota hai aur bus apni lambai kay saath jude kai terminal kay saath sanchar karti hai

What is ring or circular topology ?

tisari topology jis par vichar kia jaega vah hai ring yaa surcular topologie pratyek node do aur keval do padosi nods sey juda hua hai

yeh data keval ek disha mein yatra karta hai keval node sey angoothi kay charon ore node kay liye pratyek node sey gujarane kay baad yeh bhejane vale node mein laut aya joe ise hata deta hai

yeh dhyan rakhna mahatvapoorn hai ki pratyek note kay liye yatra pas kay bajay data parit kia gaya iska matlab hai ki javak channel par doharaye jane sey pahle signal ko parilakshit kia jaa sakata hai

What is tree topology ?

bus topology key ek bhinnata yeh hai ki ped topology aur network kaa aakar kendriya marg shakhaon mein banti aur up shakhaon mein banti kay saath ek ulte ped kaa hai joe network kaa hai

What is mesh topology ?

is prakar key topology mein pratyek node ko ek sey adhik note sey joda jata hai taki mejaban kay nichey yaa bahut vyast honey key sthiti mein ek vaikalpik marg pradan kia jaa sake yeh pee-pee network kaa vistar hai

What is fully connected topology ?

jab ek network sidhe doosare sey juda hota hai to pratyek mejaban kay beach sidha sambandh hota hai to network ko puri tarah sey is visheshata sey juda honey kay liye kaha jata hai jise puri tarah sey connectivity kaha jata hai
