Across
- 4. A data chunk contained within a frame
- 5. Cable type that usually contains four pairs of wires that can transmit and receiver data
- 8. OSI layer dealing with MAC address
- 9. Process a receiving computer follows to strip all extra header information out as data goes up the TCP/IP stack
- 10. A layer of the OSI model that keeps track of a systems connections
- 13. A structural model for ICS security that helps with network segmentation.
- 14. A discrete chunk of data sent by a NIC
- 16. Process of preparing data to go onto a network.
- 18. A 48-bit value that uniquely identifies every NIC; physical
- 19. A device that uses an IP address to forward data (not the MAC address)
- 21. OSI layer that translates data from lower layers into a format usable by Applicatiok layer (and vice-versa)
- 22. A 7 layer model that defines important functions in computer networking; encourages modular design.
Down
- 1. OSI layer dealing with TCP/IP
- 2. The windows utility most commonly used to find key system information (IP, MAC etc)
- 3. The special sequence at the end of a frame that verifies if the data arrived correctly
- 6. A layer of the OSI model that controls the segmentation and reassembly of data
- 7. A type of frame that is addressed specifically to another device's MAC address
- 11. A type of device that sends data to all systems connected to it.
- 12. A numbering system that uses base 16 to represent numbers
- 15. The system that is used to begin the frame of a MAC address
- 17. A data chunk that consists of (1) a recipient's MAC address, (2) a sender's MAC address, (3) Type, (4) data, and (5) FCS
- 20. Windows command prompt that identifies the sessions a device is connected to
