that is covered in calculus and physics.
Just a brief explanation. Vectors are a representation of coordinates just like the cartesian coordinates that you are used to. The diference is that vectors have magnitude. That is Vectors have both direction and a force attached to them. Well, not force but magnitude which means many things. For example an airplane. An airplane traves in a particular direction. You could plot this in an cartesian coordinate system with its X,Y,Z components. The airplane also has a magnitude that is the speed at which it is traveling. Depends on the plane it could be 435mph or above if its a military plane. Wind is another example. A huracane is headed towards your city. Thats the direction part. The winds speed of such huracane is 85mph. Thats the magnitude.
Vectors have some unique properties which allow you to do very nifty things. You can calculate the angle between two vector very easily. They are used extensibly in video games, air travel, sciences and what not. If you know certain properties of a vector you can find out many things about its interaction with other things like where it would intercept with something. They are very useful.

A vector is a force in a direction. Generally, on a graph, the magnitude of the vector we'll call "V" would be |V| ( a numeric value) and the direction would either be expressed by an angle (like 30, 60, or pi) or be an (x,y) coordinate pair that expresses the end of the vector. If it just gives you the x,y pair, then you can use the pythagorean theorem to find the magnitude.

The simplest explanation of a vector is that it is a scalar (a number like 1, 2, 3, etc.) with a specific direction.
For example if i say, my car is 5 feet away, i have just defined where my car is with a scalar; however if i say my car is 5 feet to the west, i have defined where my car is with a vector

An entity having a magnitude and a direction is a vector.

vectors are physical quantities whose both magnitude and direction is defined.
eg. distance is not a vector for it has only magnitude and not direction. whereas displacement has both and so its a vector.
