wireless networking

• What is the purpose of WiFi?

  To transfer data wirelessly using radio waves
• What components are required for wireless networking?

  Wireless access point and network adapter
• How are wireless networks secured?

  By using SSID, passwords, and encryption
• What does CSMA/CA stand for?

  Carrier Sense Multiple Access with Collision Avoidance

  To manage data transmission between devices
• What does SSID stand for?

  Service Set Identifier
• How do wireless networks use radio waves?

  To transfer data instead of cables
• What is a wireless LAN (WLAN)?

  A local area network using wireless technology
• What is a wireless WAN (WWAN)?

  A wide area network using wireless technology
• What is the format of a MAC address?

  6 groups of two hex digits
• What is required to connect to WiFi?

  A wireless access point and unique device code
• What standard does WiFi operate under?

  IEEE 802.11
• What is the maximum range of hotspots?

  Up to 250 meters
• How do WWANs function?

  Using phone networks with satellites and towers
• What does CSMA/CA do before sending data?

  Checks if the communication medium is idle
• What happens if the communication medium is busy in CSMA/CA?

  The device waits a random time to try again
• What is sent back after data is received?

  An acknowledgement to the sending device
• What does the RTS message do?

  It requests permission to send data
• What does the CTS message indicate?

  Permission to send data has been granted
• How can the SSID be configured?

  Set to broadcast or hidden from devices
• How can a wireless network be protected?

  By changing SSID and using passwords
• Why are wireless networks considered less secure?

  Data can be more easily intercepted
• What is WPA in wireless networking?

  WiFi Protected Access for network security
• What is the purpose of a whitelist in network security?

  To allow trusted devices to connect
• What is the purpose of a blacklist in network security?

  To block specific untrusted devices
• What are the key components of wireless networking?

  • Wireless access point (WAP)
  • Wireless network adapter (NIC)
  • Media Access Control (MAC) address
  • Service Set Identifier (SSID)
• What are the strengths and weaknesses of wireless networks?

  Strengths:

  • Flexibility in device placement
