Vector processing is a way for computers to do calculations faster. It works by breaking a calculation into many small chunks and using special hardware to do each chunk at the same time. This way, processing can be done faster than by using a normal computer processor. To help understand, think of it like a car assembly line. On the assembly line each car part is made a little bit at a time until the car is put together. Vector processing is like this but instead of building cars, it is building calculations.
