Data Communication Q.69
0. In a crossbar with 1000 crosspoints, how many statistically are in use at any time ?
- Option : B
- Explanation : A crossbar switch connects n inputs to m outputs in a grid, using electronic micro switches at each cross point, totally n x m cross points are required for crossbar switch. In general 25 percent of the cross points are used at a given time. The rest are idle so, totally 1000 cross points, so 25% = 250 crosspoint points are in use.
