Final answer:
The Federal Communications Commission (FCC) is responsible for preventing signal interference by allocating radio frequencies to ensure organized and clear communication channels.
Step-by-step explanation:
The Federal Communications Commission (FCC) improves multiple aspects of communication infrastructure, but from the options provided, the pertinent aspect that the FCC improves is the prevention of signal interference. The FCC plays a crucial role in the allocation of radio frequencies to ensure that radio stations do not overlap in their signals and that the airwaves are effectively organized. This helps to prevent interference among various communication devices such as radios, cell phones, and wireless computers. The FCC also regulates content to some extent and manages spectrum for different services, but the option closest to the described function is the prevention of signal interference.
The Federal Communications Commission (FCC) improves the aspect of communication infrastructure related to prevention of signal interference.
By allocating radio frequencies and setting national standards, the FCC ensures that radio stations do not overlap and that signals are not interfered with by other devices such as cell phones and wireless computers.
