Point-to-Point Protocol Answer: A Layer 2 WAN protocol that provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. clock skew Answer: A clock's frequency difference, or the first derivative of its offset with respect to time. time-division multiplexing Answer: A technique in which information from multiple channels can be allocated bandwidth on a single wire based on preassigned time slots. Bandwidth is allocated to ea...
