Final answer:
In an 802.11 MAC Frame, following the Frame Control field, the next component is the Duration/ID field, which indicates the time the channel will be occupied and assists in power management and channel use during CFP and CP operations.
Step-by-step explanation:
The question refers to the structure of a MAC Frame used in 802.11 wireless networking standards. The FC, or Frame Control field, is the first component of the MAC Frame. Following the Frame Control field, the next component in a MAC Frame is the Duration/ID field. This field is used to indicate the duration of time the channel will be occupied and to assist in managing the power save mode by indicating the station's sleep duration. Additionally, the Duration/ID field helps in contention-free period (CFP) and contention period (CP) operations by controlling the use of the medium.
