Point-to-point links are direct connections between two network devices, allowing them to communicate without interference from other devices. These links can be established using various technologies, such as fiber optics, wireless, or copper cables. They are commonly used in telecommunications and data networks to ensure reliable and high-speed data transfer. These links are often preferred for their simplicity and efficiency, as they reduce latency and increase bandwidth. Point-to-point links can be found in applications like internet service provider connections and private networks, where dedicated communication paths are essential for performance and security.
