ROBOTICS

• Wired network


  • Requires cables to run from one device to another in order for data to be transmitted
  • Requires an 'ethernet' cable to connect devices to the router
• Wireless network


  • Requires a NIC (Network Interface Card) which is the hardware used to connect devices to a network
  • Requires a wireless router to send and receive data packets across the network
• Wireless receiver


  Decodes the signal back to data that the computer can understand
• Wireless adapter


  Converts the data into a radio signal that can be transmitted
• Range


  Devices need to be within the range of the router to allow access to the network
• Password


  Required for security as anyone within range of the router can potentially gain access
• What is needed or can be included within a wireless network?


  • wireless connection
  • NIC
  • wired connection
  • router
• No cables required between devices in a network for data to be transmitted; requires a NIC (Network Interface Card) and a wireless router
• Cables required between devices in a network in order for data to be transmitted to and from a router
• Network Interface Card (NIC)


  The hardware required to connect a device to a wireless network
• Router


  The hardware required to send and receive data packets across computer networks
• Advantages of a wireless network


  • Cheaper
  • Users not tied to location
• Disadvantages of a wireless network


  • Can be less stable
  • Walls can obstruct signal
• Keywords


  • wireless connection
  • NIC
  • wired connection
  • router
• Bluetooth devices demonstrate the use of wireless technology
• Survey


  A tool used for data collection with questions carefully designed to gather specific answers
• Survey answers are collated and the data is analyzed


  To highlight or expose relationships between results
• Data cleaning


  Removing irrelevant answers and ensuring a consistent format throughout
• Data cleaning


  Allows the data to be transformed and presented visually to support a claim
• Online persona


  The persona you take on whilst online
• Predictions can be made before surveys are conducted
• Online identity

  • Can be different to the true identity for reasons such as:
  • Contributes to greater self confidence
  • Illegal or immoral reasons for pretending to be someone else
  • Deliberately chosen to not accurately represent who they truly are
• Reliable data


  Data that can be trusted
• Grooming


  Someone building a relationship with a young person based on trust, and potentially an emotional connection, in order to manipulate, exploit and in some cases, abuse them
• Relevant data


  Up-to-date and linked to the given context
• Grooming in an online environment


  • Allows the groomer to not be seen, thereby keeping their true identity hidden
• Types of survey questions


  • Multiple-choice
  • Short answer
  • Long answer
  • Scale
  • Yes/no
• Good survey questions


  • Specific
  • Ask for facts, not opinions
• The type of question asked needs to generate relevant and reliable data
• Questions that generate 'yes' or 'no' answers should be structured accordingly so the data can be collated and used quickly and effectively
• Reliable


  Able to be trusted
• Relevant


  Up-to-date and linked to the given context
• Survey


  A tool used for data collection
• Highlighting relationships


  Analysing data gathered to look at data split between criteria like age ranges or male/female
