A comparison of the linkutilization's and average message delays of the two dissimilar LANs is made. This lab exerciseallows students to compare two different LANs.Lab 5A LAN-WAN internet is modeled. A company has 4 LANs (presently Ethernet), one each at its 4offices. These LANs are connected via a WAN. The capacity of the line connecting the LAN’srouter to the WAN is upgraded from an initial 56 Kbps to a T1. The WAN itself uses T1 links.Traffic is modeled such that a client can request a file from its own server or across the WAN to anyof the other servers. The impact of upgrading the capacity of the link

Even so, occasionally a less than perfect concept question made it to the class. Example1a illustrates this point. The question is fine, but the choice of responses does not differentiatethose who fully understand from those with partial understanding.

Because of the friendly, yet powerful series of tutorial lessons imbedded in thesoftware, cadets quickly mastered the program, and were able to turn out impressive assemblydrawings of their design projects. Several cadet teams even learned and used Inventor’sanimation capabilities. Overall, 100+ students were trained to use Inventor in a single semesterutilizing minimal class time. Building on this initial success we have now reduced the Inventorlessons to one overview (one hour) lesson, thus permitting the cadets to self-learn using thetutorials outside of class

Whether it was because of aninfluential professor, a family member, participation in an after school, or exposure by joining abranch of the military, many women engineers point to early and middle childhood as the timewhen their eyes were opened to an exciting future in engineering.Many efforts are currently underway to increase female enrollment in university engineeringprograms.

One of the most important oral presentations,however, that engineering graduates will make is communicating in a job interview. In this case,graduates are presenting themselves to prospective employers for the purpose of being hired.This is a potentially life changing presentation, and a successful outcome is mostly based on theiroral communication skills. In addition to graduates, engineering students often face interviewsfor internships, research positions, scholarships, and jobs. Thus, interviewing well is animportant skill that they need to acquire. In courses where communication skills are an integralpart of coursework, therefore

Predictably,most hands shoot up, indicating yes.We then start a series of round robins, with each group offering a different characteristic of aprofessional; I write these on the chalkboard. While during this initial round most groups focuson superficialities, one or two groups may offer an attribute that is a defining feature of aprofessional, such as
