Options: (A)A policy where scheduler chooses the process that has the shortest expected remaining processing time. (B) A policy where scheduler discards the process that has the shortest expected remaining process time. (C) A policy where process with shortest expected processing time is selected next. (D) None of these. 12
How does a host on an Ethernet LAN know when to transmit after a collision has occurred? In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting. You can improve the CSMA/CD network by adding more hubs. After a collision, the station that detected the collision has first priority to resend the lost data. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
Options: (A)Here one system is designed as the system controller and has responsibility for managing the execution of other subsystems. (B) Each system is named as in attributebased identification and associated with one or more change requests. (C) An object class inheritance diagram, how entities have common characteristics. (D) The objective of this software development is zero-defect software. 13
