Options: (A)The science of collecting, organizing, and applying numerical facts (B) Measure of the probability that a certain hypothesis is incorrect given certain observations. (C) One of the defining aspects of a data warehouse, which is specially built around all the existing applications of the operational data(D) None of these 8
Options: (A)where the process will reside in memory, then absolute code can be generated (B) where the process will reside in memory, then the compiler must generate relocatable memory (C) if the process can be moved during its execution from one memory segment to another, then binding must be delayed until run time (D) all of the above 27
2.In memory management :A-Fixed allocation policy, B-Variable allocation policy: 1-It gives a process a fixed number of frames in main memory within which to execute. 2-It allows the number of page frames allocated to a process to be varied over the life time of the process. 3-In it a number of allocated frames are decided at initial load time.
Options: (A)A â€“ 1, 3, B â€“ 2 (B) A â€“ 1, B â€“ 3 (C) A â€“ 2, B â€“ 1, 3 (D) A â€“ 1, 2, B â€“ 3 11
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.
