Agar hum computer ko ek insaan ke roop mein dekhein, toh uska dimaag CPU (Central Processing Unit) hoga। CPU ko computer ka “brain” kaha jata hai, kyunki yeh hi sare kaam ko control aur manage karta hai। Jaise hamara dimaag decision leta hai, problems solve karta hai aur hamein instructions follow karwata hai, bilkul waise hi CPU computer ke operations ko samajhta hai। Bina CPU ke, computer kisi bhi tarah ka kaam karne mein asamarth hota hai।
History of CPU
CPU ka full form hai Central Processing Unit, aur ise computer ka “brain” kaha jata hai. CPU ki history bahut interesting aur lambi hai. Aao ise simple shabdon me samajhte hain:
1. Shuruaat (1940s-1950s)
Sabse pehle CPUs ka idea tab aaya jab computers banne lage the. Us time computers bahut bade aur slow hote the. 1946 mein pehla electronic computer ENIAC banaya gaya, lekin usme ek proper CPU nahi tha. Us samay calculations alag-alag parts ke through hoti thi.
2. Pehla CPU (1971)
1971 mein Intel Company ne pehla microprocessor banaya, jiska naam tha Intel 4004. Ye CPU chhota tha aur sirf simple calculations kar sakta tha. Iska size ek chhoti chip jitna tha, jo ek calculator me use hoti thi.
3. 1970s-1980s: Development Ka Samay
Intel ke baad aur companies bhi CPUs banane lagi, jaise AMD aur Motorola. 1974 mein Intel ne ek aur powerful CPU launch kiya, Intel 8080, jo computers me use hone laga.
Is samay CPUs kaafi improve hone lage. Pehle ke mukable ye aur fast aur smart ban gaye.
4. 1990s: Personal Computers Ka Jamana
1990 ke baad CPUs ko aur powerful banaya gaya, taki woh personal computers (PCs) me kaam kar sakein. Intel Pentium series kaafi popular hui, jo speed aur performance me bahut aage thi. Ab log computers ghar me use karne lage the.
5. Modern CPUs (2000s aur Aaj Tak)
Aaj ke CPUs bahut zyada fast hain. Inka size chhota hai, lekin ye ek second me billions of calculations kar sakte hain. CPUs me multiple cores hote hain (jaise Dual-core, Quad-core), jo ek time par kai kaam kar sakte hain. Artificial Intelligence (AI) aur gaming ke liye bhi aaj ke CPUs design kiye ja rahe hain.
CPU Kya Karta Hai?
CPU ek super-fast worker ki tarah kaam karta hai. Iske 3 main kaam hote hain:
Fetch: Computer ki memory se instructions leta hai.
Decode: Instructions ko samajhta hai.
Execute: Task ko perform karta hai, jaise game chalana ya problem solve karna.
Jaise agar aap kisi game par click karte ho, toh CPU instructions leta hai, samajhta hai, aur game ko chalane ka kaam karta hai.
CPU Ke Parts
CPU ke alag-alag parts hote hain jo milkar kaam karte hain:
ALU (Arithmetic and Logic Unit): Ye maths ke problems solve karta hai aur decisions leta hai.
Control Unit (CU): Ye decide karta hai ki CPU ko kya kaam kab karna hai.
Registers: Ye chhoti memory spaces hain jahan CPU temporary data store karta hai.
Imagine karo:
ALU ek calculator hai.
Control Unit ek manager hai jo sabko instructions deta hai.
Registers sticky notes ki tarah hain jo quick reminders ke liye use hote hain.
CPU Kaise Kaam Karta Hai?
Ek chef ki example lo:
Recipe = Program
Ingredients = Data
Chef = CPU
CPU recipe (program) ko follow karta hai, ingredients (data) ko process karta hai, aur dish (result) banata hai. Aur ye sab ek second mein millions ya billions baar karta hai!
CPU Ke Types
CPU ke alag-alag types hote hain:
Single-core CPUs: Ek time par ek hi kaam karte hain.
Multi-core CPUs: Ek saath kai kaam kar sakte hain, jaise gaming aur video editing.
Special CPUs: Khaas smartphones, gaming consoles, ya supercomputers ke liye banaye jaate hain.
Facts About CPU
CPU ka full form hai Central Processing Unit, aur ise computer ka “brain” kaha jata hai.
Pehla CPU Intel 4004 tha, jo 1971 mein launch hua tha. Iska size ek ungli jitna tha aur ye sirf basic calculations kar sakta tha.
Pehle CPU mein sirf 2,300 transistors hote the. Aaj ke CPUs mein billions hote hain!
CPU ki speed ko Hertz (Hz) me measure kiya jata hai. Aaj ke CPUs ki speed gigahertz (GHz) me hoti hai, jo millions of instructions per second ko dikhata hai.
CPU kaam karte waqt heat produce karta hai, isliye uske upar ek fan (cooling system) lagaya jata hai, jo use thanda rakhta hai.
Sirf computers hi nahi, smartphones, tablets, washing machines, microwaves aur smartwatches me bhi CPU hota hai, jo unhe chalane ka kaam karta hai.
Ek scientist Gordon Moore ne kaha tha ki CPU ki speed aur power har 2 saal me double ho jati hai. Aaj tak ye law mostly sahi sabit hua hai.
Conclusion
CPU, yaani Central Processing Unit, ek computer ka sabse zaruri hissa hai, jo use “brain” ka roop deta hai. Pehle ke simple aur slow CPUs se lekar aaj ke fast aur intelligent processors tak, CPU ki journey technology ke development ki ek kahani hai. Har device, chahe wo computer ho, smartphone ho, ya smart gadget, sabka kaam CPU ke bina adhoora hai.
Aane wale samay me CPUs aur zyada advanced, energy-efficient aur powerful banenge, jo naye innovations ko sambhav banayenge. Is tarah, CPU na sirf ek machine ka hissa hai, balki technology ke vikas ki pehchaan hai.
