Data communication refers to the process of exchanging data or information between two or more devices using electronic signals. The data or information can be in various forms, such as text, voice, images, and video. Data communication plays a vital role in modern-day communication, allowing people to communicate and share information over long distances.

Electronic signals are the primary means of transmitting data in data communication. Electronic signals are used to represent data or information in the form of binary digits (bits). The binary digits (bits) are transmitted over a communication medium using electronic signals. The communication medium can be wired or wireless, depending on the type of data communication.

There are various types of electronic signals used in data communication, such as analog signals, digital signals, and periodic signals. Let's discuss each of these electronic signals in detail.

1. Analog Signals: Analog signals are continuous signals that vary in amplitude and frequency over time. Analog signals are used to transmit audio and video signals. An analog signal can be represented as a sine wave that varies in amplitude and frequency over time. The amplitude of an analog signal represents the strength or intensity of the signal, while the frequency represents the _________ _______ ____________ __________ ____________ ________ ____ _________ ______ __________ ____________ __________.
