Processor Kya Hota Hai? 

 CPU (Central Processing Unit) ya processor, computer system ka ek mukhya component hota hai. Ye hardware device instructions ko execute karne aur calculations ko perform karne ke liye responsible hota hai. CPU ek microprocessor chip hota hai jo motherboard par install kiya jata hai.

CPU ko computer system ka "brain" bhi kaha jata hai, kyun ki iska mukhya kaam data processing aur decision making hai. CPU samanya taur par yeh karyakramon (programs) ko execute karta hai jo computer mein chal rahe hote hain.

CPU kaam kaise karta hai:

1. Fetch: CPU instruction cycle ka pahla step "Fetch" hota hai. CPU instruction register mein se agle instruction ko fetch (laata) hai. Instruction register CPU ke andar ek small memory location hota hai jahan par current instruction stored hota hai.

2. Decode: Fetch ki gayi instruction ko CPU decode karta hai. Is process mein instruction ko samajhne aur interpret karne ke liye decode unit aur control unit ka istemal hota hai. Decode hone ke baad instruction ki type, operands, aur operation determine hoti hai.

3. Execute: Decode hone ke baad, CPU execute step mein instruction ko execute karta hai. Is step mein CPU arithmetic aur logical operations, data manipulations, comparisons, aur calculations perform karta hai, jaise addition, subtraction, multiplication, division, comparison, bitwise operations, aur memory operations.

4. Store: Execute hone ke baad, CPU instruction cycle ka antim step "Store" hota hai. Isme, CPU result ko appropriate memory location mein store karta hai ya phir use output device (monitor, printer, etc.) ya storage device (hard drive, SSD, etc.) mein send karta hai.

CPU ki speed aur performance uske clock speed, core count, aur architecture par depend karti hai. Modern CPUs multiple cores, threads, aur cache memory ka upyog karte hain taki parallel processing aur multitasking ki suvidha mile.

CPU ke alawa, CPU ko support karne ke liye dusre components bhi hote hain jaise cache memory, registers, ALU (Arithmetic Logic Unit), control unit, bus system, aur cache controllers. Ye sab components saath milkar CPU ki efficiency aur functionality ko badhate hain aur computer system ko chalane mein madad karte hain.
