No, they can't

Some people never learned the first one

But can u do dis?

That’s mostly true... mostly. But you may have several ports that take the same type of cable but do different things. A simple example is that a TV may have 4 HDMI ports, but only 1 or 2 which have HDMI CEC. While a device requiring CEC to function will plug in to any of those ports, it won’t by default work correctly or at all. Ethernet ports are similar and may serve dedicated components or functions, or certain ports may carry different protocols etc. Everything seems simple when we have experience- it’s hard to grasp that what is intuitively simple to us can be hard for others. But the symbols and worlds- even “input” and “output” can be confusing, especially when someone is worried that a mistake could damage expensive equipment. An example using software is certain android devices. A mounted SD card is identified as “storage” in file view, while the onboard memory is called “sd card.” To a new user it is not intuitive and could cause confusion or even harm.

doubt.
