When connecting a ribbon cable to a connector, how do you know which direction to plug it in? A. The red line in the cable goes to the highest pin number B. The colored line in the cable goes to pin #1 C. It does not matter D. The blue or red line in the cable goes away from the power connector E. None of the above

The correct answer is: A. The red line in the cable goes to the highest pin number.

The colored line in the cable is usually a key that indicates which way the cable should be plugged in. The red line is usually the key, and it should be plugged in to the pin with the highest number. This is because the red line is usually the ground wire, and it needs to be connected to the ground pin in order for the cable to work properly.

Option B is incorrect because the colored line does not always go to pin #1. In some cases, the colored line may go to pin #2 or another pin. It is important to check the documentation for the cable to determine which pin the colored line should be connected to.

Option C is incorrect because it does matter which way the cable is plugged in. If the cable is plugged in incorrectly, it may not work properly or it may damage the computer.

Option D is incorrect because the blue or red line does not always go away from the power connector. In some cases, the blue or red line may go towards the power connector. It is important to check the documentation for the cable to determine which way the cable should be plugged in.

Option E is incorrect because the red line is usually the key that indicates which way the cable should be plugged in. The red line is usually the ground wire, and it needs to be connected to the ground pin in order for the cable to work properly.
