In pitching statistics, "IP" stands for "Innings Pitched." It measures the total number of innings a pitcher has completed in games. An inning is considered complete when three outs are recorded, and the stat is crucial for evaluating a pitcher's workload, effectiveness, and stamina over a season. It helps in comparing pitchers and assessing their contributions to their team's performance.

Communication error correction refers to techniques used to detect and correct errors that occur during data transmission. These methods ensure that the information received is accurate and reliable, despite potential disturbances like noise or interference. Common error correction techniques include Forward Error Correction (FEC), where redundant data is added, and Automatic Repeat reQuest (ARQ), which requests retransmission of corrupted data. By employing these strategies, systems can maintain data integrity and improve overall communication reliability.

Infrared light is used in fiber optic communication systems primarily because it can transmit data over long distances with minimal loss and attenuation. Its longer wavelengths enable efficient coupling into optical fibers, which reduces scattering and allows for higher bandwidth.
