Document Summary

Wired networks - more secure and better connection. Nodes - any hardware device that is connected to a network. Modem - connects network to isp (modulate, demodulate) Switch - transmits data along only 1 network. Hub - common connection point for multiple devices on a network. ******today, most routers function as combinations of router and switch/hub****** Data is broken into packets and sent over shared routes at the same time. Both the sender and receiver are communicating in real time. Sending and receiving messages at different times . not in real time. No file server - each pc is equal. Suitable for a small number of computers. Mesh network - most likely to prevent a total knockout. First four computers that were connected to network together. Phone line - uses conventional phone lines. Ethernet - use protocol for communication between nodes (one everyone uses now) Wireless - use radio waves and follow ieee standards.
