Introduction to Computer
Hello friends aap computer ko achchi tarah se jante hi honge jo ki is samay har person ke liye yah bahut hi important ho gaya hai jisko dekho ek PC ya Laptop par work karta hi hai aur to aur lockdown jaise samay me bhi computer aur electronic device ki importance bhi kafi badh gayi hai.
To dosto ab bat karte hai ki computer kise kahte hai…
Computer ek electronic device hai ye to aapne bahut hi suna hoga but aapke samne ye question bhi aaya hoga ki ye electronic devices kya hote hai aur electrical devices kya hote hai… to dosto ye ek achcha question hai to friends mai aaj is post me aapko is questions ke answer bhi bataunga to is post ko carefully read kijiyega jisase aap ko apke sawalo ka javab aapko mil sake..
Electronic Devices vah device hota hai jo jise ham kuch instruction dekar usse start kar sake aur vo apne instruction ke according work kar sake ab aap computer ka example lijiye ya microwave ya TV lijiye aapke according diye gaye instruction ke according work karta hai.
Electrical device vah devices hote hai jo without any instruction work karte hai jaise aap fan, Cooler aur bhi bahut saare cheejo ko dekhenge to aapko malum pad jayega ki yah device electrical hai ya electronic device hai.
To friends ab to aab jan hi gaye honge ki computer ki tarah ki device hai.
Definition of Computer :- Computer ek electronic device hai, Computer word letin ke language se bana hai…
Computer Word Compute word se bana hai Jiski meaning calculation hoti hai kyoki computer ka use very large scale par calculation ke liye kiya jata hai.
Computer ke father Charls Babadge hai inhone hi computer ko 1830 se banana start kia tha.
First computer ENIAC tha. Yah world ka pahla computer design hua tha.
To friends ab bat kare ki computer ka internal architecture kya kahta hai to uske liye aapko computer ke block diagram ke baare m janana hoga jo nniche diya gaya hai.
Block Diagram Of Computer.
CPU ka full Central Processing Unit ye to aap jante hi honge iska work computer ki all processing ko completely perfom karna hota hai. Computer me CPU agar naho to computer koi work perform nahi kar sakta hai.
Input ka matalab to aap jante hi honge ki user job hi computer ko deta hai vah input hota hai. Computer ko user job hi instruction deta hai vah sab Input ke antargat aata hai. Input devices jaise Scanner, keyboard, Mouse, Light pen, etc.
Output ka matalab bhi aap sabhi jante hi honge User ke input den eke bad computer ke dwara processing ke bad computer user ko jobhi provide deta hai vah user ke liye output hota hai. Output hard copy bhi ho sakta hai aur soft copy bhi ho sakta hai. Output devices jaise Monitor, printer, Plotter etc.
Memory Unit ek storage unit hoti hai jisme computer ka all data store hota hai. Chahe vah data processing ke pahle user dwara diye gaye input ka o ya fir processing ke bad provided output ka ho.
Control Unit ek aisi unit hoti hai jo compter ki all activities ko contro karta hai jaise computer ki calculation any program execution aur input processing aur output processing ko control karta hai.
ALU iska full form Arithmetic logical Unit hoti hai jo computer ke andar all arithmetic and logical calculation unit ko perform karta hai. Iska use computer me mainly programming languages ke use me kiya jata hai.
Friends ab ham aapko Computer ki aur bhi jankarri dete hai aapko agar computer ka full nahi jante hai to niche diye gaye full form ko achche se read kare ye standard full form hai…
COMPUTER :
Commonly
Operated
Machine
Particularly
Used For
Technical
Education &
Research.
To dosto ye computer ke full form the.
Hardware & Software In Computer
Dosto ab apko ye batade ki computer me kai software aur hardware hote hai jinme se kuch aap bhi jante honge jaise software ki baat kare to Microsoft Office ke Word, Excell, Power Point, Photo Editor, Video Editor, aur bhi bahut saare software hai jo computer me user ke according use kiye jate hai etc. aur aap kai saare hardware ko bhi jante honge jaise Motherboard, hard drive, CPU, Ram, Rom, and all Electronic component sab ke sab hardware ke antargat aate hai.
To dosto aapko ye to malum hua hi hoga ki computer sikhna itna bhi easy nahi hai lekin itna bhi kathin nahi hai bus thodi si mehnat se aap computer ko aasani se sikh sakte hai.
Best Computer Programming Languages in the World
Agar aap Computer science ke student hai to aapko programming language to malum hi hoga lekin agar aap nahi jante ki programming language kya hai to aap pareshan na ho ham aapko programming languages ke bare me bhi bataynge.
Dosto jaise ham aur aap hindi, English aur apni local languge me apni baato ko dusre person ko samjhate hai usi tarah computer ko bhi apni baat ko samjhane ke liye kuch languages ka use karna hota hai, aur computer ek electronic device hai isliye computer ko kuch instruction ke form me apne kaam ko poora karne ke liye kuch instruction likh kar computer ko keyboard ki help se input kiya jaata hai aur multiple instruction hone ke karan ham inhe program kahte kyoki collection of instruction is called program. Aur program ke addhar par computer language ko programming language kahte hai.
Many Programming Languages For Computer
Friends ab aapko malum hogaya hoga ki programming language kise kahte hai…
To ab aapko ye batate hai ki computer ke liye kitni programming languages hoti aur inka naam kya hai.
Vaise to computer ke liye bahut saari languages hoti hai lekin jo main hoti hai ham usi ko aapke sath share karenge…
1. C Language :- C Language ko Denis Ritchi ne 1970 ki series me develop kiya tha. C Language me aap ko kuch header files hoti hai jinka use karke ham program ko develop karte hai. Header files ka C me bahut se function hote hai jo C ke program ko run karane me help karte hai. C ke program me message ko print karne ke liye Printf( ) aur Input karne ke liye Scanf( ) function Use kiya jata hai.
2. JAVA Language :- JAVA Language ko Games Goasling ne 1991 me develop kiya tha. Aur ise 1991 me OAK ke naam se jana jata tha. Aur uske baad 1995 me use JAVA ke naam se jana jane laga. JAVA ko develop karne me 2 se 3 year ka time laga tha. Jaise C ki file Library hoti hai usi tarah JAVA ki bhi file libraries hoti hai jisme developer un file ka use program me apne task k according usse use kar leta hai.
3. C++ Language :- C++ language ko 1970 ki series me Bejarnee Strostrup ne develop kiya tha isme message ko print karne ke liye COUT aur input lene ke liye developer CIN ka use karte hai.
4. HTML :- HTML Programming language nahi balki markup language hai jiska use developers Kisi khas prakar ki website banana ke liye karte hai Website ke baare me adhik janane ke liye hamre blog me visit kare aapko Website ke bare me maximum details mil jayegi.
5. PHP :- PHP ek server side scripting language hai. Jiske program files ko ham only server par hi use kar sakte hai. PHP me kai saare predefine functions hote hai jo developers ko program banana me help karta hai. PHP jo ki ek scripting language hai isiliye usme ham program ko script ka naam denge na ki program naam denge. Isme program me meassage ko browser par display karane ke liye echo word ka use kiya jata hai.
To friends uppar diye gaye kuch programming languages ka use karke aap programmer ya web developer ban sakte hai.
Lekin uske liye pahle aapko in sabhi me se koi ek programming language ko select karke uspar mehnat karni hogi jisase aap ek achche programmer ban sakte hai.
