- 3. protects your local area networks resources from invaders that prowl the internet for unprotected networks
- 4. the time measured from when a frame enters a port to when it exits
- 10. a check of the radio frequency for activity if transmission is already under way
- 11. a network device used to connect many sometimes disparate network segments together (an internetwork)
- 12. modulator/demodulator - transmission medium so that it can be transmitted from one computer to another (historically along telephone wires
- 13. wireless LAN (WLAN) to extend further than the technology iis use is designed to deliver
- 14. ethernet term used to describe a newtowrk scenario wherin one particular device sends a packet on a network segment forcing every other device on that same segment to pay attention to it
- 18. host-based IDS software that runs on one computer to detect adnormalties on that system alone by monitoring applications sytem logs and event logs-not by monitoring the network traffic

- 17. breaking networks up into smaller networks
