What This Document Is
This document is a collection of practice problems related to data communication and networking concepts covered in CIS 66 at De Anza College. Specifically, it focuses on material from Chapters 13, 14, and 15 of the course textbook. It presents problems and their corresponding solutions, designed to reinforce understanding of key principles.
Why This Document Matters
This assignment is intended for students enrolled in CIS 66 who are seeking to test their comprehension of Ethernet addressing, frame destruction due to noise, data download times with ADSL, and STS-1 frame calculations. It serves as a valuable self-assessment tool to prepare for quizzes and exams. It’s most useful when students have already engaged with the lecture material and textbook readings.
Common Limitations or Challenges
This document provides *solved* problems. While helpful for checking work and understanding solution approaches, it does not substitute for actively working through problems independently. Relying solely on the provided solutions will not build a strong foundation in the subject matter. It also doesn’t cover all possible problem types within these chapters.
What This Document Provides
This assignment includes fully worked-out solutions for the following problems:
* P13-2: Conversion of an Ethernet address to binary representation.
* P13-8: Calculation of frame destruction due to noise in a Standard Ethernet LAN.
* P13-10: Repeating the calculation in P13-8 for a Gigabit Ethernet LAN.
* P14-8: Determining the download time for one million bytes using ADSL.
* P14-16: Calculating frames per second for a data stream carried by STS-1 frames.
* P15-4: Determining address field values in 802.11 frames based on To DS and From DS flags.
* P15-6: (Problem statement not fully included in the provided excerpt)
This preview *does not* include the full problem statements, only the solutions. It also does not include any explanations of the underlying concepts beyond what is necessary to understand the context of the solutions.
