A laptop computer is portable and has accessible ports, which makes it perfect for students and businesspeople who need to use a computer while on the move and may also need to make presentations or share files while away from their home. They have lower power and space requirements than desktops, thus conserving electricity and space while accomplishing the same work. Since a laptop is a complete computer, you aren’t dependent on peripherals like mice, keyboards and monitors, which means fewer things to fail.
