What is analog data and digital data?
BASICS OF DATA COMMUNICATIONS. ■ Analog Data – Data modulated or changed to conform to a voice. transmission format. ■ Digital Data – Data transported in a digital or discrete line code. format.
What is analog and digital data with examples?
It uses a continuous range of values that help you to represent information. Digital signal uses discrete 0 and 1 to represent information. Temperature sensors, FM radio signals, Photocells, Light sensor, Resistive touch screen are examples of Analog signals. Computers, CDs, DVDs are some examples of Digital signal.

What type of data is analog?
Analog data is data that is represented in a physical way. Where digital data is a set of individual symbols, analog data is stored in physical media, whether that’s the surface grooves on a vinyl record, the magnetic tape of a VCR cassette, or other non-digital media.
What are digital data give an example?
Digital data, in information theory and information systems, is information represented as a string of discrete symbols each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters .
Why is digital signal better than analog?
Digital signal are continuous signals This type of electronic l signals can be processed and transmitted better compared to analog signal. Digital signals are versatile, so it is widely used. The accuracy of the digital signal is better than that of the analog signal.
What is the difference between an analog and a digital device?
One of the most common examples of the difference between analog and digital devices is a clock . On the analog clock, the time is represented by hands that spin around a dial and point to a location on the dial that represents the approximate time. On a digital clock, a numeric display indicates the exact time.
What are analog and digital signals, and their differences?
An analog signal is a continuous signal whereas Digital signals are time separated signals.
What are some examples of digital data?
A familiar example of digital data is text or character strings. While textual data are most convenient for human beings, they cannot, in character form, be easily stored or transmitted by data processing and communications systems. Such systems are designed for binary data.
