La empresa FiberNet tienen un servidor de carpetas compartidas que corre el protocolo SMB, ese es utilizado para compartir un fondo de escritorio que se debe cargar en todos los computadores de la institución, se ha detectado que en algunas estación de impresión en las cuales están los puertos USB habilitados se está ejecutando malware proveniente de archivos infectados con el virus DoublePulsar, ya en dos ocasiones el servidor ha sido infectado desde estas estaciones y ha intentado dañado la información residente he intentado pasarse a otros servidores, el director del área de sistemas aconseja configurar el firewall de Windows para denegar el acceso a esas estaciones de impresión, según el caso anterior con su grupo de trabajo deben exponer en un informe técnico argumentando si esta elección es acertada o no.

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?
