Round out your study of cross-examinations by turning to "open-ended questions." Designed to help you understand your opponents' arguments, open-ended questions give you the opportunity to shift your position, thus maximizing strategic flexibility. They also allow you to set traps for your opponent. Find out how to craft-and answer-open-ended questions.

Visual images have been selected, edited, reframed—even manipulated—before they reach us, often in ways designed to elicit an emotional response. Explore the impact of reuse and mislabeling, photo selection effect, and deliberate alteration or forgery to affect how we see and feel about an image. Then, employ Label to Disable to diffuse the threat of visual misinformation.

Make sense of one of the world's most complex writing systems, and discover how spoken Japanese reflects a long-standing concern with order, hierarchy, and consensus. Why is social context so important when speaking Japanese? And what are the linguistic consequences of adopting Chinese characters in Japanese writing?

Part 03 of Computer Networking Fundamentals: Virtual Local Area Networks (VLANs)

Virtual Local Area Networks

At the end of this episode, I will be able to:

1. Identify the characteristics and importance of VLANs.

Learner Objective: Identify the characteristics and importance of VLANs

Description: In this episode, the learner will be introduced to Virtual Local Area Networks or VLANs as well as identify the purpose of implementing them in networks.

• Introduction to Network Infrastructure
  • What are VLANs? - A logical division of networked devices connected within a local area networked
  • Why are VLANs important? - VLANs allow administrators to divide ports on a switch into logical groupings. This creates multiple logical switches out of a single physical switch. This can be done for performance and security.
  • Understanding communication types
    • Broadcast - A communication message that is sent by a single device to every other device connected to the switch.
      • One to all communication
    • Unicast - A communication message that is sent by a single device to another device on the network.
      • One to one communication
    • Multicast - A communication message that is sent by a single device to a group or subset of the devices on the network.
    • Broadcast domain - A group of devices connected to a network that receive broadcast communications. This grouping can be based on physical or logical segments.
    • Segments - A divison that splits a network into smaller parts.
  • Performance benefits - VLANs create virtual boundaries that reduce the amount of broadcast traffic between devices on a larger network and ease administration.
  • Security benefits - VLANs allow network administrators to group devices together to assign an enforce security policies. Devices within a VLAN can only communicate with other devices assigned to the same VLAN.
  • How are VLANs implemented?
    • VLANs require configuration of managed switches.
    • VLANs use tagging information that is inspected by the switch to determine which VLAN the communication belongs to.
