you work as a pc technician for a real estate company. the company has decided to use laptops instead of desktops in the office so that the real estate agents can easily take their laptops with them when they leave to show properties for sale. you want to create an easy solution for the agents to quickly connect an external monitor, keyboard, mouse, a wired network connection, and an additional hard drive for storage to the laptop whenever they come back into the office. unfortunately, the laptops used by the agents don't have a built-in wired network connection. which type of device should you choose to provide all the functionality above?
