Toh aap dekhte hi hoge ke computer ka basic knowledge rakhna kitna zaroori hai aaj kal ke duniya mein. 

Pehle se pehle, aao jaante hain ke computer kya hai? Computer ek electronic machine hai jisme processor, memory aur input/output devices hote hain. Processor ko computer ka 'brain' kaha jaata hai kyunki yahi par saare calculations aur processing hoti hai. Memory mein data aur programs store hote hain, aur input/output devices humein computer se interface karne ki izaazat dete hain. 

Keyboard, mouse aur monitor - yeh hain sabse aam input/output devices jo computer ke saath aate hain. Keyboard se hum computer mein text type kar sakte hain, mouse cursor ko navigate karne ke liye use hota hai, aur monitor par hi saari output dikhti hai. Lekin aaj kal toh bohot saare aur input/output devices bhi hain jaise touchscreen, webcam, printer, speaker aur wired/wireless internet connectivity.

Computer pe kaam karne ke liye, hum operating system aur application software use karte hain. Operating system (e.g. Windows, macOS, Linux) computer mein pre-installed hota hai aur yeh software aur hardware ko efficiently manage karta hai. Application software jaise Microsoft Office, web browsers, video/audio players, games wagerah alag se install kiye jaate hain aur inse kaam kiya jaata hai.

Phir bhi, computer operate karna itna bhi mushkil nahi hai! Basic commands jaanne se hi bohot kaam ban jaata hai, jaise:

Aur agar thoda aur depth mein jaana ho, toh programming languages seekh sakte ho jisse apne aap software/apps bana sakte ho! Python, Java, C++ aur JavaScript aaj kal sabse zyada popular programming languages hain.

Kya aapko lagta hai ke computer aap sabke life ko aur aasaan bana raha hai? Mujhe toh lagta hai ke computer ne bohot kam ko streamline kar diya hai. Pahle likhna, calculations karna, dhoondna wagaira sab mushkil tha, lekin aaj kal har cheez hum click of a button par hi kar sakte hain, thanks to computers! Soch lo ke kabhi computer nahi hota toh kya hota - schools mein study karke raat bhar calculations karne padhte, banks mein customers ke accounts rakhna bohot mushkil hota, aur office work bhi bohot hi dhire hota. Hamare life mein computers ne bohot sukoon aur speed la di hai.

Lekin phir bhi, har cheez ke pros aur cons hote hain na. Kuch negative impacts bhi hain computer aur internet ke. Privacy issues, social isolation, addiction to video games/social media wagaira - yeh sab cheezein aaj kal bohot common ho gayi hain computer ke overuse ke kaaran. Cyber crimes aur data breaches bhi bohot ho rahe hain, jisse personal info leak ho jaata hai. Toh haan, overuse se bach kar balanced rahna bohot zaroori hai.

Aur aakhir mein, mein ye kahoon ke hamesha new technologies aur innovations aate rahenge jisse humare computer aur smart ho jayenge. Artificial intelligence, machine learning, cloud computing, augmented reality wagaira - yeh sab cheezien already computer mein integrate ho rahi hain. Toh stay tuned ke computer ka kya future hai!

Umeed hai dosto ke aapne mujhe follow kar liya hoga aur computer basics samajh aa gaye honge. Aur bhi janana ho toh comments mein poochho. Dhanyawad!
