Final answer:
The type of connector you would use is USB, which provides a reliable and fast connection for data transfer between an external hard drive and a Windows PC.
Step-by-step explanation:
The type of connector you would use for an external hard drive to connect to a Windows PC is USB (Universal Serial Bus). USB is a common interface used for connecting peripherals to computers, and it provides a reliable and fast connection for data transfer. External hard drives typically come with a USB cable that can be plugged into the USB port of a Windows PC.
USB connectors have evolved over time, with USB 3.0 being the most common version today. USB 3.0 offers faster data transfer speeds compared to previous versions, which is beneficial for external hard drives that deal with large amounts of data. It is important to ensure that the external hard drive and the Windows PC both have compatible USB ports, such as USB 3.0 or higher on both devices, to take advantage of the faster speeds.
