A vector may be thought of as a magnitude or size (such as speed) and a direction. So a moving car may be represented by a vector that gives the car's speed and direction.
If the magnitude and direction of a vector are chosen from populations of values in some way that makes them unpredictable-or random in other words-then that vector can be said to be random.

Is it the most efficient approach to access elements with the vector data structure?
Yes. A vector is a variable-length array but constant-time random-access is guaranteed regardless of an array's length.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
What is random scan display in CRTcomputer?
In random scan display the electron beam is directed only to the part of the screen where the picture is to be drawn. Random Scan monitor draw one picture at a time therefore they are also known as vector display.refersh rate or random scan system depends on the number of times to be displayed. Picture definition is stored in an area of memory called refresh display file.
Why is light from a common lamp nonpolarixed?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
What is the angle between vector a and vector b when mode of vector a plus vector b is equal to mode of vector a minus vector b?
90 degrees
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
What is the reverse process of vectors addition?
reverse process of vector addition is vector resolution.
What is relationship between vector space and vector subspace?
Vector spaces can be formed of vector subspaces.
Vector that shows the combined effect of two or more vector?
Resultant vector or effective vector
What is resolution of vector?
Spliting up of vector into its rectangular components is called resolution of vector
What is different between negative vector and null vector?
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
