Provides protection against network eavesdropping and signal interference and works at the physical layer of the osi model.

Shielded twisted pair (STP)

Explanation:The first layer of the OSI(Open Systems Interconnection Model) model that is physical later contains the cable which helps in elimination of the cross talk and provides ground.It has a extra layer of shield in the cable wire .It also protects the device from facing interference due to electromagnetism or eavesdropping. It is used in the environment which is noisy.

true never assume something it makes an a** out of u and me.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
