1 CHAPTER 3 Underlying Technologies Exercises 1. The Ethernet frame must have a minimum data size because a sending station must be able to sense a collision before the entire frame is sent out. The minimum size of an Ethernet network is therefore determined by the minimum frame size. 3. In the worst case, the collision would be sensed in 2 × 12.5 = 25 microseconds. 5. Let X equal the minimum number of bits. Then, X bits / 10,000,000 bits/second = 0.000025 seconds X = 10,000,000 × 0.000025 = 250 bits 250 bits / 8 = 31.25 bytes The minimum frame size would have to be larger than 32 bytes for an Ethernet net-

No, the data cannot be encapsulated in one frame. Two frames need to be sent. One frame has 1500 bytes of data; the other has 10 bytes of data plus 36 bytes of pad-ding. SECTION 2 9. See Table 3.1.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
