Traditionally, a desktop computer is a nma§n[aH$ Vm¡a na Omo ^r H$åß`yQ>a S>oñH$ na cJmH$a
computer which can be fitted and used on a Cn`moJ _| cmE Om gH$Vo h¢, S>oñH$Q>m°n H$åß`yQ>a H$hcmVo
desk. But, today it has a broad meaning. A h¢Ÿ& co{H$Z AmYw{ZH$ n[a^mfm Ho$ AZwgma Omo ^r H$åß`yQ>a

A notebook computer or laptop computer EH$ ZmoQ>~wH$ H$åß`yQ>a `m conQ>m°n H$åß`yQ>a EH$ N>moQ>m
is a small mobile computer, whose size and _mo~mBc H$åß`yQ>a hmoVm h¡, {OgH$m AmH$ma EH$ N>moQ>o ~¡J Ho$
weight is of the order of a small hand-bag. AmH$ma H$m hmoVm h¡Ÿ& BZH$mo A§Xa cJr EH$ ~¡Q>ar go Mcm`m

functions that is performed by desktop. But it
is slightly less powerful than desktop. Its cost gmao H$m`© conQ>m°n ^r H$a gH$Vm h¡Ÿ, co{H$Z BgH$s úm_Vm d
