A Computerized Sewing Machine (also called Digital Sewing Machine) is essentially an advanced model of a traditional Sewing Machine, with an integrated central computer system that drives and controls most of the processes: stitch setting, speed control, tension, etc.
In contrast to Mechanical Sewing Machines, most computerized sewing machines have a large number of built-in utility and decorative stitches, and various automatic functions that will help you save time and make the sewing process more varied and enjoyable.
And some computerized machines are also an Embroidery Machine. In addition, they can be equipped with USB ports for communication and data transfer to and from a computer.
