Computer Kya Hai- Basic Se Advanced Tak Sab Kuch

Jab hum naye hote hain kisi cheez ke liye toh dar lagta hai Shayad aapne bhi pehli baar jab kisi computer ko dekha tha toh yeh socha hoga Yeh itne saare button wala machine kya karta hai Screen chamakti hai keyboard click karta hai mouse hilta hai aur dimaag hil jata hai

Par sach kahun toh computer ek dost hai bas thoda samajhna padta hai usko toh aaj hum simple aur easy Hinglish mein samjhenge ki Computer kya hota hai uske kaam kya hote hain, aur kyun aaj ke zamane mein yeh har jagah zaroori ho gaya hai

Computer Kya Hota Hai

Computer ek electronic machine hai jo input data ko process karke useful result nikalta hai iska kaam bilkul waise hi hai jaise ek rasoiya aapke diye gaye saman se khana banata hai Computer bhi input leta hai process karta hai aur output deta hai

Computer Kaise Kaam Karta Hai

Computer teen main steps mein kaam karta hai

Input – Jab aap kuch type karte ho keyboard se ya click karte ho mouse se
Processing – CPU ya processor use information ko samajhta hai analyze karta hai
Output – Aapko result dikhata hai screen pe ya print karta hai paper pe

Computer ke Important Parts:

Part Name	Kaam
Monitor	Output dikhata hai
Keyboard	Data type karne ke liye
Mouse	Screen pe pointer control karne ke liye
CPU	Dimag hota hai computer ka
Printer	Screen ka output paper par deta hai
Speaker	Sound sunne ke liye
Scanner	Document ko computer mein lane ke liye

Computer Ka Use Kahan Kahan Hota Hai

School aur College – Notes exams online classes ke liye
Office – Emails reports data entry
Shops – Billing aur stock management ke liye
Banks – Account details check karne aur paisa transfer karne ke liye
Ghar me – Movies dekhne online shopping aur learning ke liye

Aaj ke time mein computer har jagah hai mobile phone bhi ek mini computer hi hai

Computer ka Itihaas History of Computer

Computer ka itihas bahut purana hai aaj hum jo modern computer dekhte hain unka development kai sadiyon ke research aur inventions ka result hai chaliye is development journey ko simple aur interesting tarike se samajhte hain

1. Abacus – Pehla Calculation Tool (2400 BC ke aaspaas)

Sabse pehla ginti karne ka yantra Abacus tha iska use China India aur Mesopotamia jaise deshon mein hota tha
Ye wooden frame mein beads hote the jinhe slide karke calculation ki jaati thi
Aaj bhi kai schools mein Abacus training di jaati hai

2. Napiers Bones (1617)

John Napier ek Scottish mathematician ne Napiers Bones banaya
Ye ek manual device thi jo multiplication aur division mein help karti thi

3. Pascaline (1642)

Blaise Pascal ne mechanical calculator design kiya jise Pascaline kehte hain
Ye digits ko automatically add aur subtract kar sakta tha

4. Leibniz Calculator (1671)

Gottfried Wilhelm Leibniz ne aisa calculator banaya jo multiplication division addition aur subtraction sab kuch kar sakta tha
Ye modern calculators ka base mana jaata hai

5. Charles Babbage ka Difference Engine (1822)

Charles Babbage ne pehli baar aisa machine design kiya jo automatic calculations kar sake
Unhone 1837 mein Analytical Engine ka bhi concept diya jo programming logic pe kaam karta tha
Isi wajah se unhe Father of the Computer kaha jaata hai

6. Ada Lovelace – Pehli Programmer (1843)

Ada Lovelace Charles Babbage ke machine ke liye pehli algorithm likhne wali scientist thi
Isi wajah se unhe First Computer Programmer bhi kaha jaata hai

7. 20th Century – Modern Computers ka Janm

1940s mein pehla electronic computer bana – ENIAC (Electronic Numerical Integrator and Computer)
Ye vacuum tubes se bana tha aur bahut bada size mein hota tha
Phir transistors ICs aur microprocessors aaye aur computer chhote aur powerful hote gaye

Computer ka itihas dikhata hai ki har naye invention ne agle kadam ke liye raasta banaya Aaj ka smart phone ya laptop ek lambe safar ka nateeja hai samay ke saath technology ne computer ko fast chhota aur intelligent bana diya hai
