A vector is a number (a magnitude) together with a direction (compare with scalar). A vector can be represented by an arrow whose length represents the magnitude and the direction represents the direction. For example, velocity is a vector; velocity tells you how fast something is traveling, and its direction.

A vector is a measurement that has both a numerical value, and a direction.
So, velocity is a vector. "Sam travelled east at 4 meters per second," which has both a direction and a numerical value.
Speed is not a vector. "Sam traveled at 4 m/s."
See the difference?
