Telecommunication presentation - by Maitane Solloa

This presentation includes the a detailed description of telecommunication, how it works, the components within, and an overall view of the topic.

1. TELECOMMUNICATIONS

2. Telecommunications
Telecommunications is the transmission of information over a distance for the purpose of
communication. This can involve many modes such as, voice, data, and video.
Components and functions:
Transmitter: converts data into signals suitable for transmission.
Transmission medium: the physical medium in which communications travel (For
example, wires, fiber optics, air).
Receiver: receives signals and decodes them into usable data.
Communication protocol: the rules and standards that regulate how and when
data is transmitted.
Networking equipment: this includes routers, switches, and modems that allow for
network connections.

4. Signals
Communication channels
Analog signals: continuous signals with varying amplitude and frequency. They are
represented as waves that can take any value within a given range
Digital signals: discrete signals denoted by binary digits (0 and 1). They are less
susceptible to noise and distortion than analog transmissions.
Physical medium: a medium for transmitting communications, such as copper lines,
fiber optics, or wireless radio waves.
Bandwidth: a communication channel’s capacity to transmit data, typically measured
in bits per second.
Multiplexing: a technique for merging several signals into a single transmission
medium.

5. Communication channels

6. Communication processors and software
Communication protocols: rules and conventions that regulate data
transmission format and time.
Data compression: Techniques for reducing data size so that it can be
transmitted efficiently.
Encryption: protect communication by encoding data to prevent
unauthorized access.

7. Networks
Network topologies Local and wide area networks
Star topology: devices connect to a
central hub.
Mesh topology: devices are
connected to one other.
Ring topology: devices form a closed
loop.
Bus topology: devices are connected
via a single cable.
Local area networks (LANs): covers
a narrow geographic are, usually
within a single building or campus.
Wide area networks (WANs): covers
a vast geographic region and
frequently connects numerous LANs
across cities or countries.
Network services and broadband technologies
Internet service provider (ISP): ensures internet access.
Broadband: a high-speed internet connection that enables speedier data transfer.

8. E-commerce and e-business technologies
Online shopping: purchasing and selling products and services via the
internet.
Electronic payments: digital transactions that take place online.
Supply chain management technologies: use electronic technologies to
manage the flow of goods and services from manufacturing to consumption.

10. Telecommunications play an important role in connecting people and
business all over the world, allowing for the exchange of information and
facilitating many types of communication and commerce.
Electronic Data Interchange (EDI)
The structured electronic transmission of commercial documents
between businesses.
Automated transactions: allows for the seamless exchange of data
between multiple information systems without requiring human
interaction.
