  • Lab - Observing DNS Resolution (Instructor Version) Instructor Note: Red Font Color Or Gray Highlights Indicate Text That Appears in the Instructor Copy Only
    Lab - Observing DNS Resolution (Instructor Version) Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only. Objectives Part 1: Observe the DNS Conversion of a URL to an IP Address Part 2: Observe DNS Lookup Using the Nslookup Command on a Web Site Part 3: Observe DNS Lookup Using the Nslookup Command on Mail Servers Background / Scenario The Domain Name System (DNS) is invoked when you type a Uniform Resource Locator (URL), such as http://www.cisco.com, into a web browser. The first part of the URL describes which protocol is used. Common protocols are Hypertext Transfer Protocol (HTTP), Hypertext Transfer Protocol over Secure Socket Layer (HTTPS), and File Transfer Protocol (FTP). DNS uses the second part of the URL, which in this example is www.cisco.com. DNS translates the domain name (www.cisco.com) to an IP address to allow the source host to reach the destination host. In this lab, you will observe DNS in action and use the nslookup (name server lookup) command to obtain additional DNS information. Work with a partner to complete this lab. Required Resources 1 PC (Windows 7, Vista, or XP with Internet and command prompt access) Part 1: Observe the DNS Conversion of a URL to an IP Address a. Click the Windows Start button, type cmd into the search field, and press Enter. The command prompt window appears. b. At the command prompt, ping the URL for the Internet Corporation for Assigned Names and Numbers (ICANN) at www.icann.org. ICANN coordinates the DNS, IP addresses, top-level domain name system management, and root server system management functions.

  • Cellular Technology.Pdf
    Cellular Technologies Mobile Device Investigations Program Technical Operations Division - DFB DHS - FLETC Basic Network Design Frequency Reuse and Planning 1. Cellular Technology enables mobile communication because they use of a complex two-way radio system between the mobile unit and the wireless network. 2. It uses radio frequencies (radio channels) over and over again throughout a market with minimal interference, to serve a large number of simultaneous conversations. 3. This concept is the central tenet to cellular design and is called frequency reuse. Basic Network Design Frequency Reuse and Planning 1. Repeatedly reusing radio frequencies over a geographical area. 2. Most frequency reuse plans are produced in groups of seven cells. Basic Network Design Note: Common frequencies are never contiguous 7 7 The U.S. Border Patrol uses a similar scheme with Mobile Radio Frequencies along the Southern border. By alternating frequencies between sectors, all USBP offices can communicate on just two frequencies Basic Network Design Frequency Reuse and Planning 1. There are numerous seven cell frequency reuse groups in each cellular carriers Metropolitan Statistical Area (MSA) or Rural Service Areas (RSA). 2. Higher traffic cells will receive more radio channels according to customer usage or subscriber density. Basic Network Design Frequency Reuse and Planning A frequency reuse plan is defined as how radio frequency (RF) engineers subdivide and assign the FCC allocated radio spectrum throughout the carriers market. Basic Network Design How Frequency Reuse Systems Work In concept frequency reuse maximizes coverage area and simultaneous conversation handling Cellular communication is made possible by the transmission of RF. This is achieved by the use of a powerful antenna broadcasting the signals.
