a collision domain is a logical area in a computer network where data packets can collide with one another the term is used mainly with regard to ethernet which is by far the most commonly used type of local area network lanhus a collision domain could also be defined as being all the network segments between a pair of bridges or other layer two devices the optimal size of a collision domain depends on a number of factors among them is the number of collisions as a higher number of them results in a lower efficiency of the network
Shield volcano is a type of volcano found at the divergent boundaries. SPREADING CENTER VOLCANOES. The type of volcanoes that are caused by diverging plate boundaries are called as spreading center volcanoes.When the tectonic plates drift apart from each other, the magma contents buried underneath rises upwards and erupts out through the fissures and openings on the crust.he type of volcanoes that are caused by diverging plate boundaries are called as spreading center volcanoes. When the tectonic plates drift apart from each other, the magma contents buried underneath rises upwards and erupts out through the fissures and openings on the crust.
When it reaches the surface, a volcano is formed. The magma flows out as lava, sometimes explosively. The majority of the world's volcanoes are associated with subduction zones. Since subduction zones represent plate margins, volcanoes tent to occur in lines, like the Cascade Range volcanoes or those on the Aleutian Peninsula. Once in a great while, a new volcano will form. This usually happens when an active underwater volcano produces enough lava to break the surface, such as Surtsey in Iceland in 1963.
