Consider a file system with a graphical user interface, such as Macintosh’s Finder, Microsoft’s Windows Explorer, or Linux’s KDE. The following objects were identified from a use case describing how to copy a file from a USB flash disk to a hard disk: File, Icon, TrashCan, Folder, Disk, Pointer. Specify which are entity objects, which are boundary objects, and which are control objects?

If the polar bear were taken out of the food chain what would happen to the seal population the seal population would diminish the seal population would grow dramatically the seal population would stay the same the seal population would decrease slightly

You have been supporting csm tech publishing's windows server 2016 server network for over a year. the office has two windows server 2016 servers running active directory and a number of other roles. management has informed you that a small sales office is opening in the same building three floors up. the sales manager wants to install a sales application on a server located in the sales office. this server will have limited physical security because there's no special room dedicated for it, which means it will be accessible to non-it personnel and visitors. you're considering installing windows server 2016 server core on the new server because accessing its console regularly probably won't be necessary, and this server will be managed from one of the other csm tech publishing servers. what are the benefits and drawbacks of using server core for this branch office? what are some things you should do to set up this server management environment?

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
