PROCESSOR KYA HOTA HAI AUR YE KAISE KAM KARTA HAI

     AJ HUM LOG SIKHEGE KI PROCESSOR KYA HAI.

Processor kya hai aur ye kaise work karta hai ye ap kabhi na kabhi jarur soche honge yadi yeasa hai to jan bhi ligiye ki ye kaise work karta hai aur kya jaruri hota hai.
    jab bhi computer ki bat hoti hai to waha par processor ki bat jarur hoti hai aur har koi janana chahata hai ki ye kya hai , processor sabhi computer aur mobile me hota hai aur sabhi ke kam bhi alag alag hote hai kisi ke kam jyada hote hai kisi ke kam kam hote hai par hote jarur hai kam sabhi ke sabhi.

    computer ke bhasa me kahe to processor ko hum log CPU bhi kahate hai (central processing unit) ya phir ap log processor ko computer ka dimag bhi kah sakte hai ye processor computer ke sare kam karta hai jaise hum log ko song sunana hai calculation karna hai penting karni hai ye ek sath hum log kai kam computer par kar sakte hai ye processor se hi sambhaw ho pata hai, jo bhi input hum log ise dete hai ye usaka turant Output de deta hai.

                        HOW TO WORK PROCESSOR

processor , jaise hamra dimag work karta hai same usi tarah ye processor bhi work karta hai lekin kaise ye ek chota sa hardware ye sare kam kar leta hai ,ye processor chhotis e chhoti aur badi se badi sari calculation kar lete hai wo bhi bahut hi tez gati se ye processor jo bhi Input hum dete hai wo use samajh kar hume Output de deta hai ye Output hume itana jaldi milata hai ki hum soch bhi nhi sakte hai ki ye kaise hua hai.
      processor har device me hota hai jaise computer/pc , mobile, teblet, electronic watch etc.
     
ye Processor dekhane me ek Perfect Square ki tarah hota hai jisame chhote chhote metal ke short lage hote hai  ye pin jo metal ke bane hote hai.
     ye jab work karta hai to ye jyada time tak work karne par ye heat hone lagata hai ye jyada heat ho jaye to ye work karna band bhi kar sakta hai lekin yeasa hone nhi diya jata hai isko heat se bachane ke liye ispe heat sink laga di jati aur sath me ek mini fan bhi laga diya jata hai jisase ye heat na ho sake.
    Processor kahi variant me market me available hote hai jaise, I3, I5, I7 etc.
     Processor ko sabse pahale 1971 me design kiya gaya tha Single chip Microprocessor ke rup me, ese Intel ke 3 engineer ne mil kar banaye tha .
    Processor jo sabase pahale ban ke teayar hua tha wo tha (Intel 4004 Microprocessor) .
Processor jab pahali bar bana tha to usaka size bade the lekin time ke sath sath usme badalaw kiya gaya ab processor bahut chhote ane lage hai, har kisi ke liye processor ko design kar diya gaya hai.

                 Processor ki Clock Speed.

processor ki clock speed use kahate hai jis speed se processor work karta hai, microprocessor jis speed se kisi Input ko Output kar ke jitani jadi show karta hai wo hoti hai usaki clock speed of work, processor ki clock speed ko hum log fixed number of clock ticks (cycle) ki jarurat hoti hai ye har ek instruction ko execute karata hai aur ye jitani jaldi sare ke sare instruction ko execute kar ke hume Output de de wo hoti hai processor ki clock speed.
    processor ke clock speed ko hum log  MHz me count karte hai jaise 1 MHz ka matalab hai 1 million cycles per secound, usi tarah 1 GHz ka matalab hota hai 1 thousand million cycles per secound, yadi ap apne computer ya kisi bhi device jisame processor laga hai usaki speed jitana jyada rakhege wo utana hi jyada tezi se work karega.

                       Core in Processor.

 core ka matalab ye hota hai ki processor ko kai alag alag bhago ke devide kiya gaya hai jise hum log Core kahate hai, core kai prakar ke hote hai jaise single core , dual core etc.
Example of Core.
Dual   Core - 2 core
Quad Core - 4 core
Hexa  Core - 6 core
Octa  Core - 8 core
Deca  Core - 10 core
Processor speed depend on more Core .



             HOW TO WORK ON PROCESSOR

processor ki jo design hoti hai wo bahut ki complex hoti hai aur ye design hi processor ki jan hoti hai kyonki hai kyonki jaise jaise core badate jate hai ye design aur complex hote jate hai, processor 4 process me work karta hai jaise ( fetch, decode, execute, write back ).

  1. Fetch - is ka kam processor ko hamare dwara diya instraction ko lekr jana aur aur use process kar ke hume dena.
  2.  Decode-  computer me ya kisi bhi device me jab ko work karte hai hum log to processor use binary me samajhata hai to isaka kam use hamre dwara diya gaya menual ko decode kr dene ka kam karta hai ye.
  3. Execute- is unit ka kam hota hai ki processor ko kya kam karna hai aur processor ka kaun sa unit work kar raha aur kaise work kar raha hai ye batane ka kam karta hai jaise man lo hume koi arithmetic operation karne hai to wo kaise to usake liye processor ALU ka prayog karta hai.
  4.  Write Back- jaisa ki nam se pata chahata hai ki ye kya kam karega , iska kam ye hai ki processor abhi tak kya kam kiya aur use ab kaha pe Output dena hai ye sab kam write back ke dwara hota hai.
