Aaj se 15 years peche chale jain to jo computer hamain ma-ya-sar the wo intehaye sada the for example XT processor ke hamil computers me giney chuney ajza hote the jese ek mother board, ek display card, ek i/o card aur ziyada se ziyada 2mega bit ram ke sath tashkeel pane wali ye machine ager-cha aj ke dor ke mutabeq bohat mehdod istadad ki hamil thi layken is waqt in ki hesiyat bhi inkalabi machines ki sit thi. Ek mechanical type writer ya ek electronic type writer se behter kam baher-hal in main bhi ho sakta tha kun ke ye machine word processor ki badolat editing ki behter saholeyat farham kerta hai.
Is ke bad AT machine ka dor aya. Es me pehli machine 286 aur phir 386 ke naam se aye. In me windows ke ibtada-e version install ho sakte the aur window ki badolat in me mouse ka istamal bhi mumkin ho gaya. Es leye in ke kam kerne ke tareke aur raftar me bhi khatir-kha farq para. Es ke bad 486 ka dor aya. Ye 66 se le ker 100 mega hertz ki machine apne se pehle mojod machines ki nisbat ziyadah fa-al thi. Ye apne dor ki inkalabi machine is leye kehla sakti thi ke in mein multi media machine ka agaz howa. Aaj agar-cha ziyada arsa nahi guzra layken computer ki dunya me ek zaber dast tabdili aa chuki hai. Computer hardware mein ab is kadar tanow aa gaya hai ke is ke tamam ajza ka aaht-ta kerna bohat mushkil hai. Ab PC mehaz ward processor ke leye istamal nahi hota hai balke is se kai kam leye jate hai. jese k es ne tamam daftar amor sanbhal leye hain. Multi media khsosiyat ke badolat ab communication mein es ko istamal kiya ja raha hai. Iinternet kay zarye dunya simat gai hai. Log ek dosre se internet ke zarye telephonic guftugu ker rahe hai. Screen ke zarye chating ek aam si bat hogai hay. E-mail ke zarye ab ap apne peghamaat dunya k ek kone se dosre kone tak pohcha rahe hain. Aaj ki machine ne insan ko jaha roshnai aur qalam se azad ker diya hai waha fun ki dunya me bhi is ke aa-ne se bohat bari tabdili ho rahi hai. Ab ek computer user artist bhi hai.
Jaha tak computer ke is ertaqa-e safar ka taluq hai to jin machines ka upper zikar howa hai in key aa-nay mein kafi arsa laga hai leyken Pentium series shuroo hoe is ki release bohat tezi se howa aur palak jhapkte he hum P4 tak pohanch gaye hain.
Ager computer ke ajza ko mehaz ek nazar me dekha jaye to is me baher se mushayedah kerne per humay chand hi chezain nazar aaien gi. Pehle hum yaha inhe chezon se ap taruf badi-ul-nazar dikhai de rahi hoti hai.
