The absence of a safeguard, or a weakness in a system that may possibly be exploited is called a(n)?
A vulnerability is a weakness in a system that can be exploited by a threat.

Which of the following would be MOST important to guarantee that the computer evidence will be admissible in court?
It has to be material, relevant and reliable, and the chain of custody must be maintained, it is unlikely that it will be admissible in court if it has been tampered with.
The following answers are incorrect:
It must prove a fact that is immaterial to the case. Is incorrect because evidence must be relevant. If it is immaterial then it is not relevant.
Its reliability must be proven. Is incorrect because it is not the best answer. While evidence must be relevant if the chain of custody cannot be verified, then the evidence could lose it's credibility because there is no proof that the evidence was not tampered with. So, the correct answer above is the BEST answer.
The process for producing it must be documented and repeatable. Is incorrect because just because the process is documented and repeatable does not mean that it will be the same. This amounts to Corroborative Evidence that may help to support a case.
Which of the following computer design approaches is based on the fact that in earlier technologies, the instruction fetch was the longest part of the cycle?
Complex Instruction Set Computer (CISC) uses instructions that perform many operations per instruction. It was based on the fact that in earlier technologies, the instruction fetch was the longest part of the cycle. Therefore, by packing more operations into an instruction, the number of fetches could be reduced. Pipelining involves overlapping the steps of different instructions to increase the performance in a computer. Reduced Instruction Set Computers (RISC) involve simpler instructions that require fewer clock cycles to execute. Scalar processors are processors that execute one instruction at a time.

What is the proper term to refer to a single unit of IP data?
IP is a datagram based technology.
DIFFERENCE BETWEEN PACKETS AND DATAGRAM
As specified at: http://en.wikipedia.org/wiki/Packet_(information_technology)
In general, the term packet applies to any message formatted as a packet, while the term datagram is generally reserved for packets of an 'unreliable' service.
A 'reliable' service is one that notifies the user if delivery fails, while an 'unreliable' one does not notify the user if delivery fails. For example, IP provides an unreliable service.
Together, TCP and IP provide a reliable service, whereas UDP and IP provide an unreliable one. All these protocols use packets, but UDP packets are generally called datagrams.
If a network does not guarantee packet delivery, then it becomes the host's responsibility to provide reliability by detecting and retransmitting lost packets. Subsequent experience on the ARPANET indicated that the network itself could not reliably detect all packet delivery failures, and this pushed responsibility for error detection onto the sending host in any case. This led to the development of the end-to-end principle, which is one of the Internet's fundamental design assumptions.
The following answers are incorrect:
IP segment. Is incorrect because IP segment is a detractor, the correct terminology is TCP segment. IP is a datagram based technology.
IP frame. Is incorrect because IP frame is a detractor, the correct terminology is Ethernet frame. IP is a datagram based technology.
IP fragment. Is incorrect because IP fragment is a detractor.

Which of the following media is MOST resistant to tapping?
Fiber Optic is the most resistant to tapping because Fiber Optic uses a light to transmit the signal. While there are some technologies that will allow to monitor the line passively, it is very difficult to tap into without detection sot this technology would be the MOST resistent to tapping.
The following answers are in correct:
microwave. Is incorrect because microwave transmissions can be intercepted if in the path of the broadcast without detection.
twisted pair. Is incorrect because it is easy to tap into a twisted pair line.
coaxial cable. Is incorrect because it is easy to tap into a coaxial cable line.
