Document Summary

Application servers store and distribute application software for each system on the network. Database servers are dedicated to an organization"s database storage, queries, and retrievals. In large organizations, e-mail servers handle the large volume of incoming, outgoing, and internal e-mail. A communications server handles all communications between the network and other networks, including managing internet connectivity. Network topology refers to the physical or logical arrangement of computers, transmission media (cable), and other network components. Combining multiple topologies into one network is known as constructing a hybrid topology. A bus topology uses a single cable or bus to handle transmission of signals between computers. Tis is most often used in p2p networks. Data collisions can occur easily if two computers transmit data at the same time because bus network is composed of one main communication medium (single cable). Ring topology are laid out in a circle. Data flows in a circle from device to device in one direction only.
