This paper discusses some of the basic concepts about the term “grid”, “grid computing” and some other important and useful terms related with it. In this paper, the working of grids which means which component is used by the grid for its efficient operation, the analogy of the computational grids with the electrical grids, the major areas where the grids are being used at present and where the grids will be used in the coming decades, the features of grid systems ,the grid computing technology which is becoming popular these days , the operating principles of the grid systems, the advantages and disadvantages of computing grid ,challenges in front of grid-computing that need to be resolved have been discussed.
