24. Ethernet - Cat5 - Twisted to allow for longer runs.






25. The attacker sends a SYN request to the victims machine and the victim machine allocates resources for that request and sends a SYN/ACK back. The attacking machine doesn't respond however - but instead sends another SYN and continues to do so until t






26. A type of hash function used to produce a checksum - which is a small - fixed number of bits - against a block of data. This is used to detect errors after transmission or storage.






27. A network that mimics the brain






28. An attacker spoofs the source IP in a packet header - to make a ping request appear to have originated from the future victim's network - then the responding network responds in full force to these requests and brings down the victim's network.






29. When you know something from a source - and can infer other related information based off of what you know - when you may not necessarily have access to that data normally.






30. Degaussing is the process of reducing or eliminating an unwanted magnetic field. The Degausser is what actually performs the degaussing.






31. Accepting all packets






32. A compact disc that contains data only accessible by a computer. All modern CD-ROM drives can also read audio CDs. It is possible to produce composite CDs containing both data and audio with the latter capable of being played on a CD player - whilst
