Thread kya hota hai computer science mein?

1.  Lightweight: Threads lightweight hote hain compared to processes kyunki unhe create aur destroy karne mein kam resources ka istemal hota hai.
2.  Share Resources: Threads ek hi process ke andar hote hain, isliye unhe process ke resources jaise ki memory space, files, aur sockets ka access milta hai.
3.  Context Switching: Jab ek CPU multiple threads ko execute karta hai, tab usme context switching hota hai, jismein CPU ek thread se doosre thread par switch karta hai.
4.  Types of Threads: Kuch operating systems support karte hain user-level threads aur kernel-level threads. User-level threads application ke andar manage kiye jaate hain, jabki kernel-level threads operating system dwara manage kiye jaate hain.

Computer science mein thread ek execution context hai jo ek process ke andar hota hai aur independent tasks ko execute karne ka capability provide karta hai. Har process ek ya multiple threads ko contain kar sakta hai. Threads multiple tasks ko simultaneously execute karne ki capability provide karte hain, jisse overall performance improve hoti hai.

Threads ka istemal primarily concurrent programming mein kiya jaata hai, jahan ek application ke multiple tasks parallel taur par execute kiye jaate hain. Har thread apni apni sequence of instructions execute karta hai, independent of other threads, lekin sabhi threads ek hi process ke andar execute hote hain aur unhe process ke resources ka access milta hai.

Kuch key points about threads include:

1. Lightweight: Threads lightweight hote hain compared to processes kyunki unhe create aur destroy karne mein kam resources ka istemal hota hai.
2. Share Resources: Threads ek hi process ke andar hote hain, isliye unhe process ke resources jaise ki memory space, files, aur sockets ka access milta hai.
3. Context Switching: Jab ek CPU multiple threads ko execute karta hai, tab usme context switching hota hai, jismein CPU ek thread se doosre thread par switch karta hai.
4. Types of Threads: Kuch operating systems support karte hain user-level threads aur kernel-level threads. User-level threads application ke andar manage kiye jaate hain, jabki kernel-level threads operating system dwara manage kiye jaate hain.

Threads ka istemal multi-threaded applications develop karne, parallel computing, aur asynchronous programming mein hota hai. Tasks ko concurrently execute karne se performance improvements aur better resource utilization achieve kiya ja sakta hai.
