Summary of lesson 3: Telecommunications, The Internet and Wireless Technology

1. Telecommunications, The
Internet and Wireless
Technology

2. Telecommunication Systems
● Serves to communicate and share information electronically and digitally
● Does this by transmitting digital data, video and audio
● Made up of multiple components:
- Computer
- Terminals (input and output devices)
- Communication processors
- Software where the communication happens

3. Functions of Telecommunication Systems
● Share information digitally
● Provide an interface between sender and receiver to make the
communication possible
● Route the sent information (leading it on the most efficient path for fast
receiving)
● Control the flow of information

4. IT Infrastructure for Businesses
● The way hardware, software and network are connected in a business is
known as Enterprise Networking
Network inside the business:
● Computers are connected in a LAN network and can act as servers
● They are connected together with POS systems, as well as different offices so
information is easily shared between all of them
Outside the business:
● The enterprise also communicates data with the public network
infrastructure (internet, telecommunication, mobile communication)

5. World Wide Web
● Information space where information is identified through unique global
identifiers known as URL links
● Utilizes text, visual graphics and sound
● Allows for wireless web

6. Wireless Web
● Allows to access information from the internet (world wide web)
● There are different wireless web standards through which websites are built
and we can access them from:
- Wireless Application Control (WAP)
- Wireless Markup Language (WML)
- Microbrowser
- I-Mode

7. Application of Wireless Web
● Before the wireless web existed, individuals within and outside of an
organization had to make direct calls to communicate information with each
other
● The wireless web enables to use CRM systems which facilitates the
communication of information through an interface that all parties involved
in the system can easily see without the need to actually speak to each other,
leading to way smoother working
