Computer kya hai,(computer kaise kam karta hai)

Computer kya hai kaise kam karta hai

Computer ek electronic device hai,jo data ko process karne and store karne ke liye use kiya jata hai.

Computer kya hai(what is computer) computerke bare bat karenge. aasan language me
kaha jai to computer ek electronic device hai.ye ans aap sabhi ko pahle se hi pata ho.

me aapko aaj basic computer kya hai ye batana chahta hu usme se shayad aapko kuch
pahle se pata par mera makshad hai ki aapko puri computer ke bare me jankari di jai na ki

adhi adhuri mujhe pata hai ki aapko computer ki basic janakri pata hai.par kya aapko ye pata hai ki ye kaise kam karta hai,kisne isse pahle banaya,kis kis dor se hokar ye guzra hai.computer me kitna changing dekhne ko mila estne salo me.

Aaj jo computer ham use kar rhe hai iske piche kai scientist ka mehnat ka natija hai.Wahi adhi adhuri gyan se to acha pura gyan aapke pass ho aaj me aap logo ko is article

computer kise kahte hai.iske mukhay ang kya hai.computer ka full form and ye kaise kam
karta hai.ke sath sath aap logo ko is device ke bare me puri jankari dena chahata hu. to fir deri kis bat ki chaliye shuru karte hai and jante hai ki computer kya hota hai.

Computer kya hai

Computer ek machine hai ek aisa electronic device hai, jise banaya gya hai jankari ke sath kam karne ke liye yah word computer,latin ke word “computer” se liya gya hai,eska word hai colculation karna.

Input data–processing– output data

Computer kisne banaya tha mordern computer ka janak CHARLES BABBAGE ko kaha jata hai.kyuki unhone hi sabse pahale Mechanical computer ka design kiya tha,jisse analytical
engine ke name se bhi jana jata hai.isme punch card ki help se data ko insert kiya jata tha.

To computer ko ham ek aisa advanced electronic device kah sakte hai jo ki row data ko input ke tor me user se leta hai, fir us data ko program (set of instruction) ke dowran

process karta hai our aakhir ke pariyam ko output ke rup me karta hai,ye dono numerical and non numerical(arithmetic and logical) calculation ko process karta hai.

Computer ka full form kya hai

C- Commonly
O- Operated

History of computer

kab se computer ka development shuru kiya gaya. lekin officially computerki development ko generation computer ke mutabik classify kar diya gaya hai.ye 5 hiso me bata hua hai. jab bat computerki generation ki aati hai tab iska tatpar hai jaise jaise computer me vikash hote hai.

computer kaise kam karta hai

Input(data): inputwo step hai jisme ki raw information ko input device use karke computer me dala jata hai.ye koi letter,picture ya koi video bhi ho sakata hai.

Process: process ke dowran input huye data ko instruction ke anushar processing ki jati hai.ye puri tarah se internal process hai.

Output: output ke dowran jo data pahle se process ho chuki hai usme result ke tor me show kiya jata hai.our yadi ham chahe to is result ko save kar ke memory me rakh bhi sakate hai future ke use ke liye.

Motherboard

motherboard

kisi bhi computer ka circuit board ko motherboard kaha jata hai.ye ek patali plate ki tarah dikhata hai jaise CPU,memory,connector hard drive and optical drive ke liye,expansion card

video and audio ko control karne ke liye, iske sath sath computer ke sabhi ports ko connection dekha jai to motherboard computer ke sare ports ke sath directly ya in directly juda hua hota hai.

CPU/Processor

kya aap jante hai central processing unit yani CPU kya hai.isko bhi kaha jata hai.ye computer case ke anadar motherboard me paya jata hai. ise computerka dimag bhi kaha

jata hai.ye kisi computer ke bhitar hi hi rahe sare runing process ke upar nazar rakhata hai jitna jada ek processor ki speed hogi utani hi jaladi ye processing kar paiga.

RAM:

Ram ko ham random acess memory ke name se bhi jante hai.ye system ka short term memory hota hai. jab bhi kabhi computer kuch calculation karta hai.tab ye temporarily us

result ko ram me save kar deta hai. agar computer band ho jaye to ye data bhi kho jata hai. yadi ham koi document likh rahe ho tab ushe kharab hone se bachane ke liye hame

bich me apne data ko save kana chahiye. save karne se data hard drive me save ho to ye lambe time tak rah sakti hai.ram ko megabytes(MB) or gigabytes(GB) me mapa jata hai.jitana jada ram hoga utana hamare liye acha hai.

Hard Drive:

Hard drive wo component hai jaha software,document and dusre file ko save kiya jata hai . isme data lambe time tak store hokar rahta hai.

Power Supply unit:

                                     power supply unit

Power supply unit ka kam hota hai ki main power supply se power lekar ushe jarurt ke anushar dusre components me supply karna.

Expansion Card:

Sabhi computers ke expansion slots hote hai jisme ki ham future me koi expansion card ko add kar sake,inahe PCI (peripheral component interconnect) card bhi kaha jata hai.lekin

aaj kal ke motherboard me built in hi kai slots pahle se hote hai.kuch expansion card ke name jo ham purane computers ko updates karne ke liye use kar sakte hai.

. Video card
. Sound card
. Network card
. Bluetooth card (Adapter)

software and hardware

computer hardware ko ham koi aishi physical device kah sakte hai jise ham apne computer me use karte hai,wahi computer software ka matlab hai codes ka collection jise ham aapne machine ke hard drive me install karte hai hardware ko chalane ke liye.

exampale ke tor pe computer monitor jo ham padhane ke liye use karte hai,mouse jise ham navigate karne ke liye use karte hai ye sab computer hardware hai.wahi internet

browser jisase ham website visit karte hai,and operating system jisame ki wo internet browser run hote hai.aisi chizo ko ham software kahte hai. ham ye kah sakte hai ki ek computer software and hardware ka misharan hai dono ki saman bhumika hai,dono sath milkar hi koi kam kar sakte hai.

Types of Computer:

Jab bhi ham kabhi computer word ka use sunte hai tab hamare man me bas personal computer ka hi picture ata hai.me aap logo ko bata du ki computers bahut sare prakar ke

hote hai.jarurt ke anushar ham inka use karte hai jaise ki ATM paise nikalne ke liye,scanner kisi barcode ko scan karne ke liye,calculator kisi badi calculation karne ke liye .ye sare different types ke computers hai.

1. desktop:

Bahut se log desktop computerka use aapne gharo school and aapne personal kam ke liye liye karte hai.inka design kuch is prakar se hote hai ki inhe ham aapne desk par rakh sake . inke bahut sare parts hote hai jaise Monitor,keyboard,mouse computer case.

2. Laptop:

laptop ke bare me aap to jante hi honge jo ki batter powered hote hai,ye bahut hi jada portable hote hai jisme inhe kahi bhi our kabhi bhi le jaya ja sakta hai.

3. Tablet:

Ab bat karte hai tablet ki jise ham handheld computer bhi kahte hai kyuki ise badi aashani se hatho me pakada ja sakta hai.
isme keyboard and maouse nhi hote, bas ek touch sensitive screen hota hai jisme typing and navigation ke liye use kiya jata hai. Example-iPAD.

4. Servers:

Ek servers kuch is prakar ka computer hai jime ham information ke aadam pradan ke liye use karte hai.example ke tor pe jab bhi ham koi chiz internet me khojate hai wo sari chize servers me hi store hoti hai.
