Question

24. In full duplex, transmission signals are transmitted in only one direction; one station is the transmitter and the other is the receiver 25. A reduction in strength as signal is transmitted from source to destination is referred to attenuation 26. In simplex communication, transmission signals are transmitted in both directions. 27. The peak amplitude is the maximum value or strength of the signal over time; typically, this value is measured in volts. 28. The Spectrum of a signal is the range of frequencies that it contains. 29. The place where telephone companies terminate customer lines and locate switching equipment to interconnect those lines with other networks is the called NAP 30. Gateway-Device that nodes use for access to other PC's within the same ne twork 31. Total number of IP addresses in a Class B network is 224

true and false questions

Answer 1

In full duplex, transmission signals are transmitted in both directions at a time. 24) False rightarrow Reduction in signal strength due to transmission is called attention 25) True rightarrow In simplex communications, the signals are transmitted only in one direction 26) False rightarrow The peak amplitude is maximum value of strength of a signal over time. 27) True rightarrow the spectrum of a signal is the range of frequencies occupied by a signal 28) True. rightarrow Telephone companies terminal customer lines and Locate switching equipment to interconnect those lines with other networks is called central office. 29) false NAP rightarrow Network Access point is a public network exchange facility where internal service provides connected with one another rightarrow Gateway rightarrow Is used to connect two services in different networks ie, two different networks but not PC�s within same network 30) False rightarrow Total number of IP address in class B networks 2^16. 31) False (Given 2^24)
