A continuous-time signal has values for all points in time in some (possibly infinite) interval. A discrete time signal has values for only discrete points in time.

What is the difference between discrete and continuous-time?
A primary difference between discrete-time and continuous-time models is that the latter take into account the exact time interval between measurements while the former do not—discrete-time models assume equally spaced time-intervals.
What is the difference between continuous and discrete time control system?
A discrete system is one in which the state variable(s) change only at a discrete set of points in time. E.g. customers arrive at 3:15, 3:23, 4:01, etc. A continuous system is one in which the state variable(s) change continuously over time.

Time and Frequency Terminology
A discrete-time signal is a sequence of values that correspond to particular instants in time. The time instants at which the signal is defined are the signal's sample times, and the associated signal values are the signal's samples.
What is a continuous-time signal?
A continuous-time (CT) signal is a function, s(t), that is defined for all time t contained in some interval on the real line. For historical reasons, CT signals are often called analog signals.
