Assume that the execution time for a program is directly proportional to instruction access time. The access to an instruction in the cache is 10 times faster than access to an instruction in the main memory. If an instruction is not found in the cache, i. e., cache miss, it is fetched from the main memory to the cache and then fetched from the cache to be executed. Assume that a requested instruction will cause cache miss has a probability of 0.08. Let the speedup factor is defined as the ratio of program execution time without the cache to program execution time with the cache. a. Calculate the speedup factor to execute such a program.
b. using this assumption, assuming that the cache is 20 times faster than the main memory.

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

Before you record your own voice, you should a. record other people's voices b. warm up and practice difficult names c. listen to your favorite songs d. read a transcript of a good radio news segment

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
