The Geographic Grid Ptolemy‚ a Roman mathematician‚ created the geographic grid. This grid is a system of invisible lines that span the globe. The grid has been used for over 2‚000 years as a reference for finding the location of a fixed position on Earth. There are certain components that make up the grid. Meridians run vertically and come together at the north and south poles. The center meridian‚ the Prime Meridian‚ divides the earth into eastern and western hemispheres. Parallels run horizontally

Grid Designing Abstract: In an increasing number of scientific disciplines‚ large data collections are emerging as important community resources. Grid computing has emerged as an important new field‚ distinguished from conventional distributed computing by its focus on large-scale resource sharing‚ innovative applications‚ and‚ in some cases‚ high performance orientation. The foundation of a grid solution design is typically built upon an existing infrastructure investment. However‚ a grid

5. Managerial Grid The x/y axis on the grid consist of two behavior dimensions‚ concern for people and concern for production. Concern for people is the degree to which a leader considers the needs of employees when deciding how tasks or jobs should be done. This can be personal or professional development. This behavior dimension moves along the y-axis. Concern for production is the degree to which a leader emphasizes objectives and productivity goals when deciding how tasks or jobs should
