Assignment Wireless

In this assignment, we were to watch videos by Professor Messer that discussed various topics such as Network Types and Wireless networking. Network Type materials where DSL, cable, satellite, fiber and bluetooth technologies are discussed and Wireless Netwworking where 802.11 wireless networking and related wireless standards are presented here Below are the assignment questions that we had to answer.

Question Set 1: 4.3 - Network Types

  1. What high speed type of network runs over telephone lines?

    Digitial Subscriber Line (DSL) run over telephone lines.


  2. What type of high speed network runs over coax cable?

    Cable Modems run over coaz cable.


  3. Of the popular types of home high speed networks utilizes non-terrestrial networks that typically have a high latency?

    Satellites utilize non-terrestrial networks that have a high latency.


Part 2

  1. What was Bluetooth originally designed to replace?

    Bluetooth was originally designed to repklace wired connections in Personal Area Networks.


  2. What type of network would Bluetooth create?

    Bluetooth creates Personal Area Networks.


Question Set 2: 4.3 - Wireless Networking

  1. What is the IEEE family of standards for wireless networking?

    802.11 is the standard for wireless networking.


  2. How do the different members of the 802.11 family differ?

    The members differ in speed, frequency range, distance and channels.


  3. Which 802.11 standard utilizes MIMO?

    802.11n utilizes MIMO.


  4. Which 802.11 standard represents an improvement, and backwards compatibility, with 802.11b?

    802.11g represents an improvement and backwards campatibility with 802.11b.


Part 2

  1. What was the original encryption utilized by 802.11?

    Wired Equivalent Privacy was the original encryption utilized by 802.11.


  2. When were WEP cryptographic vulnerabilities identified?

    WEP crytographic vulnerabilities were identified in 2001.


  3. What type of encryption was created to improve on WEP but utilize the same hardware?

    Wi-fi Protected Acceess (WPA) was the encryption created to improve on WEP.


  4. What type of wireless encryption is based on the Advanced Encryption Standard (AES)?.

    WPA2 is based on the Advanced Encryption Standrad (AES).


Part 3

  1. In wireless networking, what is an SSID?

    SSID is the Service Set Identifier


  2. Disabling SSID broadcast is an important security configuration

    answer


  3. What is the general security term used to describe the disabling of SSID broadcast?

    Security through Obscurity.


  4. Can MAC addresses be spoofed?

    Yes, MAC addresses can be spoofed because they are not encrypted.


  5. What wireless networking standard supports speeds up to 600 megabits per second?

    a802.11n speeds up to 600 megabits per second.
