Giant lycophyte trees of Earths early forests (see Figure 26.27) had microphylls, whereas ferns and seed plants have megaphylls. Write a short essay (100150 words) describing how a forest of lycophyte trees may have differed from a forest of large ferns or seed plants. In your answer, consider how the type of forest in which they grew may have affected interactions among small plants growing beneath the tall ones.
1.4 Delay, Loss, and Throughput in Packet-Switched Networks Types of Delay in Packet-Switched Networks o Processing Delay The time required to examine the packet’s header and determine where to direct the packet. Can also include other factors, such as the time needed to check for but-level errors in the packet that occured in transmitting the packet’s buts from the upstream node to router A. TYpicalli in the order of microseconds or less o Queueing Delay Occurs as the packet waits to be transmitted onto the link. Typically in the order of microseconds or milliseconds in pra
