Question

Most networking media send data using _____ in which data is represented by only two discrete states: 0s and 1s.

A. digital signals

B. contiguous signals

C. ramp signals

D. exponential signals

Answer 1

Answer:

i think digital signals

Explanation:

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.

Answer 2

Answer: A) Digital signals

Explanation:

• Digital signal is a signal that helps in describing about the data in sequential manner in form discrete bands or binary values.
• The electrical signal containing data is converted into bits that can be represented through two digital values i.e. 0s and 1s.
• Other options are incorrect because contiguous signal is regular adjacent signal. Ramp signal is represented as increment in magnitude with time
• Exponential signal is based on sine and cosine signal that is two real time signal.
• Thus, the correct option is option(A).
