Telecommunications systems allow for the exchange of data between two entities using technology such as electromagnetic waves or physical mediums. They include smaller systems like telephone networks and larger systems like the internet. Data is conveyed using electrical signals known as carrier waves that are modulated digitally or analog to carry information. Telecommunications systems connect terminal nodes through transmission links to enable communication between two terminals. The main components are transmitters that convert information into signals, receivers that convert signals back into usable information forms, computers for processing data, and communication software and processors to manage networks and transmit/receive data. Signals travel via these systems using either analog waves like for voice calls or digital bits like ones and zeros for data transmission.

2. It is used for data exchange between two entities that
includes, the use of technology. For broadcasting information
the technology uses electromagnetic waves or a physical
medium.
For eg: we can take Internet as a larger scale. When we look
into smaller scale, we can choose
Telephone networks
Amateur radio operators
Corporate wide area networks
Fire communication systems

3. Basically, you know how data is conveyed? It is conveying
using electrical signals known as carrier wave or carrier. For
carrying information we need some modulation, it is
categorized as digital or analog.

4. It is a bunch of links, terminal nodes or any other terminal
nodes, so that it is able to enable telecommunication
between two terminals. Finally, links from the transmission
connect the nodes together.

5. • Transmitter
 It act as an information source, taking information then
convert into a signal for transmission. It produces radio
waves with the support of antenna, in the form of
telecommunication and electronic systems.
• Receiver
 The task of receiver is to receive the signals and converts
into required method. The information may be in the form
of audio or video or digital signals

6. •Components
Computers for processing information
To send or receive data using terminals or any input/output
data
For managing network use communication software
For reception and data transmission, get support from
communication processors

7. •Signals
Data travels via telecommunication systems uses analog and
digital electromagnetic signals
Analog used for voice communication via communication
medium
Digital transmits data as bit format such as one bit and zero
bits
