In data communication, signals refer to the variations in physical quantities that carry information over a medium. These signals can be analog or digital, with analog signals representing data as continuous waves and digital signals encoding data in discrete binary values. The transmission of these signals enables the exchange of information between devices over various channels, such as wired or wireless networks. Effective signal transmission is crucial for ensuring data integrity and communication reliability.

What are the key Tasks must be performed in data communication system?
In a data communication system, key tasks include signal generation, where data is converted into signals for transmission; transmission, which involves sending these signals over a communication medium; and reception, where the signals are captured and converted back into usable data. Additionally, error detection and correction mechanisms are essential to ensure data integrity during transmission. Finally, proper protocol management is crucial for ensuring that different devices communicate effectively and understand each other.
What is the purpose of the physical layer in data communication?
to convert a frame into a series of signals to be transmitted on the local media

What is the use of bts?
BTS is Base trans-receiver station in Mobile communication. It is the base station which receives signals from mobile station. It sends the data or signals to the mobiles.
What Technology used to modify analog signals to make them suitable for carrying data over a communication path?
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
How they communicate with spaceship from earth?
Communication with spaceships is typically done using radio waves. The spaceship sends signals back to Earth, and vice versa, through antennas on both ends. These signals can carry information such as telemetry data, commands, and communication with astronauts on board.
What does Communication satellite transmit?
Communication satellites transmit various types of data, including television signals, internet connectivity, telephone communications, and radio broadcasts. They act as relay stations in orbit, receiving signals from ground stations and amplifying them before sending them back to other locations on Earth. This enables long-distance communication and facilitates global broadcasting and data services.
Why are microwaves ideal for transmitting satellite communication signals?
Microwaves are ideal for transmitting satellite communication signals because they have a short wavelength, allowing them to carry large amounts of data quickly and efficiently over long distances without interference from the Earth's atmosphere.
What energy transformation are in a wifi?
In a Wi-Fi system, electrical energy is transformed into electromagnetic energy. The router converts electrical signals into radio waves, which then transmit data wirelessly. When a device receives these signals, the radio waves are transformed back into electrical signals, enabling communication and data transfer. This process allows for wireless connectivity and data exchange between devices.
