Host a is transferring a file of size s to host b using tcp. a sends the file data in fixed size packets equal to the maximum segment size (mss), a predetermined value. b sends an acknowledgement immediately upon receiving a data segment. let r be the round trip delay between a and b. the advertised receiver window size of host b is w . in this problem, we assume the tcp connection is already established and that the transmission time is negligable. tcp performs the slow start and congestion avoidance mechanisms, and there is no error or packet loss during transmission.

The most common battery cable terminal is a that provides a large surface contact area with the ability to tighten the terminal onto the battery post using a nut and bolt.

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;
