Computer ki jankari hindi |
Computer ek electronic machine hai , jo different type ke calculate bahut kam time me puri suddta ke sath solve karta hai. Computer word latin language se liya hai jiska matlav calculation hota hai.
Computer ke kho j American scientist “Charls Babej” ne kiya hai. Isliya inhea father of computer bhi kahate hai.
Parts of computer
1.) Input device :- Keyboard , Mouse
2.) Precessor :- C.P.U.
3.) Output :- Moniter, Printer
1.) Input device:-computer ke andar jo data bheja jata hai, use imput kaha jata hai. Computer ke jndar data aa work input devices , jesse:-Mouse , Keyboard ke dubara kiya jata hai.
2.) Processor:- Processor computer ka important part hai. ess part me input kiya gaye data par processorka work hota hai, and usska antim result ready kiya jata hai. computer me process karne balee devices ko C.P.U. kahate hai.
3.) Output:- Processing dubara ready kiyea gaye result ko jees devices ke upper pirapat kiya jata hai, unnhe output devices khate hai, computer me use hone bali important output devices, MoniterM printer and speaker etc. hai.
Importance of computer
Computer ke kaee importance hoti hai , jo computer ko etana useful banata hai. some imortance are –
1.) Speed:- Computer very fast speed se work kartne bale machine hai, jo hajaro, lakho calculation ko second se bhi kam time me solve kar sakti hai. Computer ke speed mapne kee kuch ekaee yaha hai-
i. Mini second:- 1/1000=1.0001 N/s hajarba part
ii. Micro second:-1/1000000 N/s Ten lakhba part
iii. New second:-1/100000000 N/s Araba part
2.) Accuracy:- Computer dubara ke gaye calculations pure hoti hai, computer kebal uss esthati me wrong result deta hai, jabke computer ko dee gaye suchana and nirdes wrong ho.
3.) Memory:-- Computer ke memory bahut adik hoti hai , yaha sabhi nirdes and aakado ko esme save rak sakte hai. Computer ke andar do tarah ke memory hoti hai.
I. Internal Memory:-yaha memory computer ke andar hoti hai. yaha two types ke hoti hai.
Ø RAM(Random Access Memory):- yaha memory computer ke temparory hoti hai atha hum jo bhi data computer me input karte hai. Bo sabse pehale RAM par store hota hai and tab tak RAM par banee rahaty hai. jab tak usse na save kiya jae save karne ke bad yaha data baha permanent memory par save ho jaha hai, lakin hum input kiya gaye data ko save nahi kar pate or ess bich power cut ho jata hao to hamare dubara input kiya gayadata ess temparary memory se mit jata hai . yani RAM ek “Black Boord” ke tarah work karti hai jis par likha hua data dubata perapt nahi kiya ja sakta.
Ø ROM(Readonly Memory):- Yaha computer ke andar permanent memory hoti hai jis par likha hua data power cut hone apr bhi delete nahi hota hai.
II. External Memory:- Aase memory jo computer ke bahar issthit hoti hai. Usse External Memory kehate hai. Ya bhi memory hati hai or een par likha hua data delete nahi hota hai.
For Ex.:- CD , Floppy ,Pen drive , Hard disk etc.
4.) Auto Mation:- Computer user dubara diya gaye nirdesso dubara work karta hai, Hume kebal suchnaye or nirdes hi computer ko dene hote hai jab ke process and result formation computer kar leta hai or usska result screen par dikha deti hai.
