a collision domain is as the name implies a part of a network where packet collisions can occur a collision occurs when two devices send a packet at the same time on the shared network segment the packets collide and both devices must send the packets again which reduces network efficiencyollisions are often in a hub environment because each port on a hub is in the same collision domain by contrast each port on a bridge a switch or a router is in a separate collision domain
Type: Composite volcano with caldera. The 1883 explosion on an uninhabited island in Indonesia was one of the most catastrophic in history. Before the eruption, this island in the Sunda Straits between Java and Sumatra islands was made up of three stratovolcanoes that had grown together.ype: Composite volcano with caldera.

Composite Volcano. Introduction. A composite volcano is also known as a stratovolcano. These volcanoes form tall, conical shaped mountains. Most of the Earth's active volcanoes have formed a ring around the Pacific Ocean. There are 452 stratovolcanoes in the Pacific Ring of Fire.he lava is less fluid and forms thick lava flows on the sides of the volcano. Sometimes the lavas form small dome volcanoes over the vent in the crater of a stratovolcano or on its steep sides. Eruptions of statovolcanoes. Stratovolcanoes erupt less frequently than shield volcanoes which have formed over hot spots.
