  1. 2. is a hardware component, typically a circuit board or chip, which is installed on a computer so it can connect to a network.
  2. 3. This automatically assigns IP addressing to a device. a client-server protocol in which servers manage a pool of unique IP addresses.
  3. 4. an error-reporting protocol that network devices such as routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets.
  4. 6. is a feature or characteristic in operating systems which enables computers to self-configure an IP address and subnet mask
  5. 13. sequence of characters that uniquely names a Wi-Fi network.
  6. 15. a signal sent to a host that requests a response.
  7. 16. This statically assigns IP addressing to a device.
  8. 17. Includes wired and wireless network interface cards (NIC) and network devices such as switches, wireless access points (APs), routers, multipurpose devices, and more.
  9. 18. is a collection of IP standards designed to optimize the process of allocating IP addresses by forming unique identifiers.
  10. 19. A unique string of characters that identifies each computer using the Internet Protocol to communicate over a network
  11. 20. allows prioritization of specific traffic types.
  12. 21. is a network diagnostic tool used to track the pathway taken by a packet on an IP network from source to destination.
  13. 24. defines the range of IP addresses that can be used within a network or subnet.
  14. 25. is an application or computer that sends, receives, and relays email.
  15. 26. allows a temporary opening in the firewall to allow data to specific inbound ports or a port range for an application or game.
  16. 27. a network that provides services to an untrusted network.

  1. 1. used to specify the MAC addresses that are allowed on the wireless network.
  2. 3. a node that enables a connection between networks in order to allow machines on other networks to communicate.
  3. 5. It is used to automatically assign an IP address to a device in an IP network when there is no other assignment method available.
  4. 7. A unique number that is part of the NIC.
  5. 8. is a temporary address for devices connected to a network that continually changes over time.
  6. 9. a device that connects two or more packet-switched networks or subnetworks
  7. 10. A command line utility that is used to display and manage the IP address assigned to the machine.
  8. 11. a computer network security system that restricts internet traffic in, out, or within a private network.
  9. 12. allows traffic to specific ports.
  10. 14. a 32-bit number assigned to a computer as an address on the internet and does not change.
  11. 16. Involves knowing how networks are interconnected to support the needs of a business.
  12. 22. The unique identifier that serves as the name of your computer or server.
  13. 23. allows devices to dynamically add themselves to a wireless network without intervention/configuration.
