what is the difference between a vector and a reservoir?

A disease reservoir is analogous to a water reservoir. But instead of supplying water, a disease reservoir serves as a supply for a virus or other pathogen. Vector: Any living creature that can pass an infection to another living creature.

Vector are implemented as dynamic arrays with list interface whereas arrays can be implemented as statically or dynamically with primitive data type interface. Size of arrays are fixed whereas the vectors are resizable i.e they can grow and shrink as vectors are allocated on heap memory.

The main difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths.

The difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths. A raster graphic, such as a gif or jpeg, is an array of pixels of various colors, which together form an image.

A source is the origin or starting point of something typically. The river was the source of the water. A resource is something of value that you can use. Water is a natural resource. A source is the origin or starting point of something typically.

Vectors are the physical quantities that have magnitude, answering how much; as well as direction, answering where to. For example: implies displacement of towards . A unit vector is a type of vectors such that the magnitude of it is one unit. For example: implies unit displacement towards .

The main difference lies in what the output of the operation is. A vector product takes two input vectors in a space and returns an output vector in the same space. A scalar product takes two input vectors in a space and returns a scalar value, usually either in the real field or the complex field.

Lesson Summary A vector is an ordered list of elements and differs from a scalar by having both magnitude and direction. They are normally written either vertically as column vectors or horizontally as row vectors.

Image: The difference of two vectors. The difference of two vector x=b−a is formed by placing the tails of the two vectors together. Then, the vector x goes from the head of a to the tail of b.

Displacement is the vector difference between the ending and starting positions of an object. Velocity is the rate at which displacement changes with time. It is a vector, too. The average velocity over some interval is the total displacement during that interval, divided by the time.

A unit vector is vector used to specify only direction. Direction does not have magnitude and therefore that's why the magnitude of the unit vector is always unity (ONE). A position vector is used to tell how far and in which direction a point is with respect to some arbitrarily chosen origin.

Vector and ArrayList both uses Array internally as data structure. They are dynamically resizable. ... But, ArrayList increases by half of its size when its size is increased. Therefore as per Java API the only main difference is, Vector's methods are synchronized and ArrayList's methods are not synchronized.

Vector images – what's the difference? Raster images are made up of a bunch of tiny pixels, while vector images are made from mathematical paths.

Algebraic - Treats a vector as set of scalar values as a single entity with addition, subtraction and scalar multiplication which operate on the whole vector. Geometric - A vector represents a quantity with both magnitude and direction.

It is important to note that vector elements are accessed by index while unordered_set elements are accessed by value. This leads to the operation with the greatest difference in time complexity between the two: find. A vector is just a list, and as such, find takes O(n).

Vector is similar with ArrayList, but it is synchronized. ArrayList is a better choice if your program is thread-safe. Vector and ArrayList require space as more elements are added. Vector each time doubles its array size, while ArrayList grow 50% of its size each time.

In vector calculus, the curl is a vector operator that describes the infinitesimal rotation of a vector field in three-dimensional Euclidean space. At every point in the field, the curl of that point is represented by a vector.
