Everyone knows the importance of laptops. Today people are starting to replace desktops and computers with laptops because they are lightweight, portable, and small in size as compared to computers. We can see that the use of laptops has become common just like mobile phones. At that time mobile phones were available in many houses as laptop use is very common in middle-class families. they can be used daily for internet banking, online education, business, entertainment, bill payment, online recharge, etc.
