MTU Networking and Maximum TCP Packet Size. Definition: The MTU is the maximum size of a single data unit (e.g., a frame) of digital communications. MTU sizes are inherent properties of physical network interfaces, normally measured in bytes. The MTU for Ethernet, for instance, is 1500 bytes.
Harlem Shake videos are a great example of contagious diffusion, or when a cultural trend is transmitted from person to person from an original source to numerous others, similar to a virus.
Cultural diffusion is the spread of cultural trends across locations and involves both expansion diffusion and relocation diffusion. Relocation diffusion occurs when a person migrates from their home and shares their culture with a new location. Expansion diffusion occurs when a trend is spread from its originating place, outward. There are several forms of this type of diffusion including contagious, hierarchical, and stimulus diffusion.
