CPU Kya hai or kaise kaam karta hai-सीपीयू क्या है और कैसे काम करता है?

Kya Aapko pata hai ki ye CPU Kya Hai? Kyun ise Computer Brain bhi kaha Jata hai? Aise bahut se sawal hai jo aksar kai Logon ko presan karte hai .Jaise hamare Body me hamara Brain hamare saare Parkiryao ko control karta hai thik waise hi ek computer me bhi CPU uske bhitar aur bahar ho rahe sabhi parkiryao ko niyantaran karta hai. Khaas isliye hi CPU ko brain of the computer bhi kaha jata hai.

CPU Kya hai or kaise kaam karta hai
Yah user ke dwara diye gaye sabhi instruction ko handle karta hai,aur yah cpu ke capacity ke uper hai ki vo kitni jaldi aur kis hisab se un instruction ko process karta hai.Jitni jaldi vo kar sake use utna hi behtar ya efficient CPU kaha jata hai.chaliye CPU ke baare me kuch jankari lete hai.

Jaise jaise Technology me advancement ho rahi hai waise waise hame jyada se jyada complex processes ko process karne ke liye Fast CPU ki jarurat ho rahi hai jo in complex calculation ko sahajta se kar sakte aur sath bahut se Processes ko handle kar sake,is chiz ko multitasking bhi kaha jata hai.khash isliye Software aur Hardware Developers hamesha behtar CPU ko banane me lage huwe hote hai kyunki unki demand bhi badhti hi jati hai.ek example lete hai samajhne ke liye.

Jab aap koi Laptop ya koi desktop kharidne ke liye jate hai shop me tab vo aapko kuch Technical Specification ke baare me batate hai jaise ki 64 Bit Quad core intel I5,I7,I9 Etc yadi aap computer ke field se nahi hai tab aapko isse kuch bhi samajh nahi aayega.lekin aakhir me vo kya kah raha hai aapko palle kuch bhi nahi padega.ghabraye  nahi kyunki aaj ham inhi Technical Specification,Core,CPU ke baare me hi jankari pardan karne wale hai.

har 6 mahine me market me aapko naye Processor wale CPU najar me ayega.aise bhi naye user ke liye kathin hota hai unhe kaun se Processor ka chunav karna chahiye agar vo koi naya system kharid rahe hai tab kyunki aapke kaam ke hisab se aapki Requirement hoti hai.

Aise me agar aapko basic kaam hi karna hai tab aapko jyada advanced CPU lene ki koi bhi jarurat nahi kyunki aise kaam ke liye aapka normal CPU bhi vo kaam aaram se kar sakta hai aur aapko jyada paisa ko kharch karna parega.lekin sahi jankari na hone ke karan hi log hamesha shop ke bahkave me aa jate hai aur jyada kimti CPU kharid lete hai jo ki unhe kabhi bhi jarurat nahi hoti hai.

Isliye aaj maine socha ki kyuna aap logo ko Central Processing Unit(CPU) kya hai aur kaise kaam karta hai iske bare me sahi jankari pardan karu jisse aapko sahi CPU chunav karne me asani ho to fir bina deri kare chaliye shuru karte hai aur CPU kya hota hai hindi me iske baare me jante hai.

सीपीयू क्या है ? ( What is CPU in Hindi)

Kya aapko pata hai CPU ka pura naam kya hai? CPU ka Full Form  hai Central Processing Unit. yah ek chota sa Piece ka hardware hota hai jo computer Program ke sabhi instruction ko process karta hai.yah computer system instruction ko process karta hai yah computer system ke sabhi important tasks jaise ki arithmetical,Logical,aur Input/Output operations ko handle karta hai.

CPU ko kuch is parkar se banaya jata hai ki jaha billions ki matra me microscopic transistor ko single computer chips me rakh ja sake.yah transistor ki madd  se hi sabhi Calculations ko kiya jata hai jinki jarurat Programs ko run karne ke liye kiya jata hai jo ki system ke memory me store hote hai. 

CPU ko isliye Computer ka brain bhi kaha jata hai kyunki sabhi instruction ,chahe vo kitne bhi simple kyun na ho,sabhi ko CPU ke madhyam se hi jana Hota hai.Example ke liye aapko koi alphabet type karte hai jaise ki L tab ye screen me appear hota hai.ise screen me appear hone me CPU ka hath hota hai.

Isikaran CPU ko Central Processor Unit ke naam se bhi refer kiya jata hai, aur short me ise Processor kaha jata hai. isliye jab aap koi electronic store me koi device ka technical specification dekh brahe hote hai tab vaha per jo Processor specification hota hai vo hi CPU hai.

Jab ham CPU ke alag alag prakar ke bare me discus karte hai tab isse hamara tatparya uske speed se rahta hai.jaise ki vo kitni jaldi sabhi function ko purn karta hai.hame apne kaam karne me speed ki hi jarurat hoti hai,jitni jaldi hamare kaam ki processing hogi utni hi jaldi ham koi naya kaam ko asani se kar sakte hai.

Jaise jaise hamare instruction complex bante hai jaise ki 3D animation,Video files ki editing etc aise me hame jyada behtar CPU ki jarurat hoti hai.isliye processor technology me jo bhi technological advancees huwe hai vo sabhi ke piche speed hi mahtavpurn karan raha hai.

CPU ko ham bahut se naam se jante hai jaise ki processor Central Processor, Ya microprocessor etc.yah apne Software aur hardware se jo bhi instruction receive karta hai chahe vo jitna bhi chota kyun na ho use ye process karta hai isliye Computer ka yah ek bahut hi major hissa hai 

CPU technology me jo bhi advancements hota hai usme ek chiz ko jyada ahmiyat di jati hai vo ye kaise transistor ko chote se chota kiya ja sake.aise isliye kyunki isse un CPU ko jyada efficient banaya ja sake aur unki speed ko kaye guna tak badhya ja sake.

is chiz ke baare me sabse pahli baar ek scientists  jinka naam Moore hai unhone kaha tha isliye is chiz Moore's Law bhi kaha jata hai.

CPU ka Full Form Kya hai ?

CPU ka full form  "Central Processing Unit" Agar aap ise hindi me Translate karenge to ya hota hai “केंद्रीय प्रक्रमन एकक“.

CPU ko Hindi me Kya Kha Jata Hai ?

CPU ko hindi me केंद्रीय प्रचालन तंत्र या केंद्रीय प्रसंस्करण इकाई kaha jata hai.

CPU ka Functions?

To chaliye jante hai CPU ke kuch mahatvapurn Features ke Baare me.

  • CPU ko computer ka brain kaha jata hai.
  • CPU sabhi parkar ke data Processing Operations karta hai.
  • ye Data,Intermediate results,aur instruction(|Program) ko store karta hai.
  • Iske saath ye computer ke sabhi parts ke sabhi kaam Ko Operation ko ko control karta hai.

CPU kaise kaam karta hai?

Aapko ye janna jaruri hai ki CPU kya kaam karta hai.waise to ham ye jante hi hai ki CPU jo karey(Function) Karta hai vo bahut Important hote hai lekin ab ham janenge ki kaise ye CPU kaam karta hai.CPU ke utpatti se abhi tak isme aise bahut saare improvements kiye gaye hai pichle kaeye saalo me.

In sare improvements ke bavjud bhi CPU ke jo basic function hai vo abhi btak same hai jo basic function hai vo fetch,decode,aur execute.to chaliye inke baare me vistar me jante hai.

Fetch

Jaise ki sabd se malum parta hai isme instruction ko receive kiya jata hai.isme instruction ka matlab hai ki series of number jise ki RAM se CPU tak paas kiya jata hai partyek instruction ek chota sa hi part hota hai ki operatorion ka isliye CPU ko ye pata hona chahiye ki koun sa instruction next aa raha hai.current instruction address ko program counter ke dwara rakha jata hai.

Fir PC aur instruction ko Instruction Register (IR) me place kiya jata hai.uske pashchat PC Length ko badhaya jata hai jisse use reference kiya ja sake next instruction address per.

Decode

Ek bar instruction ko fetch aur store kar liya gaya IR me, fir CPU us instruction ko paas kar deti hai ek aisi circuit me jiski instruction decode kahte hai ye fir us instruction ko convert karti hai signals me jo ki baad me paas kiya jata hai.dusre CPU ke parts ke dwara aage ke action ke liye.

Execute

ye aakhir ka step hota hai,jisme decode instruction ko CPU ke relevant parts per bheja jata hai complete hone ke liye fir resulta ko aksar write kiya jata hai CPU register me,Jaha per unhe Reference kiya ja sakta hai Later instruction ke dwara. yaha aap inhe apne calculator ke memory function ke tahat samjh sakte hai.

CPU Important Parts ke Bare me ?

Yaha per janenge ki CPU ke components kya hai aur kaise vo kaam karte hai.waise to CPU ke important three 3 Components hote hai.

  • Memory ya storage Unit
  • Control Unit
  • Arithmetic Logic Unit (ALU)

Memory Ya Storage Unit

Ye Unit System ke Instruction,data aur Intermediate results ko store karte hai.ye Unit dusre sabhi units ko information bhi pardan karte hai jarurat parne per ise internal Storage Unit ya main memory ya Primary Storage ya Random Access Memory(RAM) bhi kaha jata hai.

Iski size affect karti hai iske speed,power aur Capability per.Primary memory or Secondary memory do aise memories hote hai jo ki Computer me mahjood hote hai

Memory Unit ke Functions Kya hai ?

  • Yah Processing ke Jarurat huwe sabhi data aur instruction store karti hai.
  • Yah sabhi Intermediate results of processing ko store karte hai.
  • Yah final results of processing ko store kari huwe hoti hai jab unhe output device me release tab kiya bhi nahi huwa hota output device me.
  • Sabi inputs aur outputs ko main memory ke dwara transmit kiya jata hai.

Control Unit

Ye unit Computer ke sabhi parts ke operations ko control karti hai lekin ye kaye actual data processing operators nahi karti hai.

Control Unit ke Function Kya hai ?

  • Ye data aur instruction ke transfer ko control karne ke liye kaam me aata hai jinhe ki computer ke dusre units ko transfer karne ke liye kiya jata hai.
  • ye Computer ki sabhi unit ko manage aur coordinate karne ke liye kiya jata hai.
  • ye memory se instruction ko prapt karta hai,unhe interpret karta hai,aur un operation ko computer tak direct karne ke liye istemal kiya jata hai.
  • yah Input/Output device ke sath communicate karta hai data transfer ke liye aur storage se resultas ke liye.
  • Ye koi bhi chiz process nahi karta aur na hi koi data Store karta hai.

Arithmetic Logic Unit (ALU)

is Unit me Two 2 Components hote hai jinhe ki kahte hai,

  • Arithmetic Section
  • Logic Section

Arithmetic Section

Is Arithmetic Section ka function hai ki ye sabhi Arithmetic operations jaise ki addition,subtraction,Multiplication,aur division ko perform karti hai.sabhi complex operations ko uper bataye gaye hai operations ko repetitive use kar hi liya jata hai.

Logic Section

Is Logic Logic Section ka jo important function hai vo ye ki sabhi logic operation jaise ki comparing,selection,matching,aur merging of data ko perform karti hai.

Types Of CPU ( CPU kitne prakar ke hai ?

Jaise ki hum jante hai ki Computer CPU jise ham short me Central Processing Unit kahte hai ek bahut hi vital components hai jo ki sabhi instruction aur calculation ko handle karta hai jinhe use send kiye jata hai dusre computer component aur peripherals se.softwere Programs kis speed se kaam karti hai ye CPU ke uper nirbhar karta hai ki vo kitne Powerful hai.

Isliye ye mahatavpurn hai ki aap sahi CPU ka chunav kare jisse vo sabhi kaamo ko jarurat ke anusar handle kar sake.abhi puri duniya me do sabse bade leading CPU manufactures hai Intel aur AMd jinke paas apne hi parkar ke CPu maujod hai.
