- The definition of a grid is a pattern of horizontal and vertical lines spaced out at regular intervals, forming squares or rectangles.
The lines on graph paper are an example of a grid.
- a framework of parallel bars; grating
- a network of evenly spaced horizontal and vertical bars or lines, esp. one for locating points when placed over a map, chart, etc.
- a system for distributing electric power throughout a region
- on a speedway, the order in which racing cars start
- Elec. a conductive framework of metal plates in a storage cell or battery, that contains lead or a lead compound, esp. a lead oxide, and reacts with the electrolyte
- Electronics any gridlike or spiral-shaped electrode positioned between a cathode and anode to control the flow of electrons or ions in an electron tube

grid - Computer Definition
(1) Any interconnected set of nodes such as the electric power network or a communications network.
(2) "The Grid" is a nickname for Internet2. See Internet2.
(3) In a vacuum tube or gas-filled electron tube, the grid is a perforated electrode through which electrons may pass. The term typically refers to the control grid in a triode, tetrode or pentode vacuum tube. In these cases, the grid is used to control the amount of current flow between the cathode and plate (anode). As the voltage potential is varied on the control grid, the amount of current allowed to pass through also varies. Relatively small fluctuations in the grid's potential can control substantially larger amounts of current flow through the tube. This phenomenon is referred to as "gain." Tetrodes and pentodes use additional grids to regulate current flow and effect gain. See screen grid and suppressor grid.
