Answer: Method of gaining ac-cess to the network media. (6)
●● access port
Answer: Hub connection to which each network cable is connected. (1)
●● acoustical echo
Answer: Condition that takes place when a microphone and a speaker
are in close proximity or the audio is improperly adjusted, causing
feedback. (12)

(1)
●● active partition
Answer: Describes the partition that contains the operating system files
the computer should use to boot. (17)
●● adaptive cut-through
Answer: Frame-forwarding technique that operates as cut-through until

Answer: Measurement of noise introduced outside the cable jacket,
typically caused by other net-work cables in close proximity. (2)
●● American National Standards Institute (ANSI)
Answer: Private, nonprofit organization that does not develop standards,
but rather prompts voluntary conformity and standardization. (1)

Answer: Early attempt to standard-ize data codes. (5)
●● amplifier
Answer: Electronic device designed to raise a signal's amplitude. (2)
●● analog signal
Answer: Signal that has a contin-uous range of values, much like a
wave. (2)
●● analog-to-digital converter (ADC)
Answer: Computer chip designed to change an analog signal to a digital
signal. (12)
