Q
  1. a device must be put into pairing mode. this is a mode which makes the device discoverable and broadcasts information such as:
  • Name
  • Bluetooth class
  • Services that the device can use
  • Technical information, such as the features or the Bluetooth specification that it supports
  1. select the device from the searching device such as a laptop
  2. a pin may be asked for to authenticate the connection
  3. the pin is saved by the device and future connections should be automatic

Q

when using this connection type to an ISP you may find:

  1. one channel carrys telephone calls
  2. a second channel provides the download of data (usually fast)
  3. a third channel provides the uploading of data (usually slower)

NOTE

each channel is seperate meaning they can all be used independently without interferig with each other

Q

describe

Software Defined Networking (SDN)

A

this seperates the control plane and the data plane of a network device.

the data plane is left handled by the device while the control plane is managed on a server in a central location

the benefits of this are better manageability and security
