49. A portion of a program that can run separately from and concurrently with other portions of the program. Also called thread of execution.






50. [1] A device that is the central connecting point of a LAN. A hub is little more than a multiport repeater taking incoming signals on one port and repeating them to all other ports. Ethernet hubs have been largely replaced by Ethernet switches.. [2]
