Handheld কি?

A handheld computer, also known as a handheld PC or a personal digital assistant (PDA), is a portable, battery-powered device that is small enough to be held in one's hand. It typically has a touchscreen display and a stylus or a small keyboard for input and can perform a variety of tasks such as managing contacts and calendars, browsing the internet, sending and receiving emails, taking notes, and storing and playing multimedia files. Handheld computers were popular in the early 2000s before being largely replaced by smartphones and tablets.
