An uninformed search is a searching technique that has no additional information about the distance from the current state to the goal. Informed Search is another technique that has additional information about the estimate distance from the current state to the goal. Uses knowledge to find the steps to the solution.

Breadth-first Search:
Breadth-first search is the most common search strategy for traversing a tree or graph. This algorithm searches breadthwise in a tree or graph, so it is called breadth-first search.
BFS algorithm starts searching from the root node of the tree and expands all successor node at the current level before moving to nodes of next level.
The breadth-first search algorithm is an example of a general-graph search algorithm.
Breadth-first search implemented using FIFO queue data structure.
Advantages:

BFS will provide a solution if any solution exists.
If there are more than one solutions for a given problem, then BFS will provide the minimal solution which requires the least number of steps.
