Laptops are now a days more useful than computer.laptop contain attached keyboard and monitor.itcan be used by charging two to three hours. Childrens use laptops mostly for playing.like that hcl laptops are used for office purpose, by adults.
Cost of laptop is nearly minimum 25000rs. to maximum one lakh.we can use laptop by giving any password to open.like that there is no other chance to another one to open it.so we can maintain secretely, so that there is no chance to go out of any information without password permission. So these days laptop using people population in crores.they are in different sizes like that cost is depended.small size laptops are simple to handle, we can carry those through hand, they are mostly cheap and gaurentee. So this is my review on laptop.
