Topic 1 Summary - Connected Digital systems and Smart Devices

What is SIP - session Initiation Protocol used for

• SIP is used as stateless signaling for setting up VoIP and media streaming

• SIP is used for managing database connections.
• SIP is a protocol for file transfer between computers over wide area networks

• SIP is used for data encryption in networks.

What protocols are used within the Transport layer in the TCP/IP 5 layer model

• Hypertext transfer protocol (HTTP)

• File transfer protocol (FTP)

• Transmission control protocol (TCP)

• User datagram protocol (UDP)

• Internet protocol (IP)

How many bit address format is IPv6

• 128

• 64

• 255

• 28

how do two handsets transmit and receive data such as an SMS text message.​

• Data is sent through Bluetooth connections between the handsets.
• SMS messages are transmitted via Wi-Fi without any mobile network.
• Handsets use infrared signals to send SMS messages directly.
• message coded into binary form and transferred between towers using electromagnetic signals and then decoded into text.

Explain FTTC

• FTTC connects homes directly to the internet without any street cabinets.
• FTTC is a wireless broadband technology that does not require cables.
• FTTC uses only fiber optic cables for the entire connection.
• FTTC is a broadband technology that connects fiber optic cables to a street cabinet, using copper lines for the final connection to homes.

What are the phases of the internet in order

• Connectivity

• Internet of everything

• Collaborative experiences

• Networked Economy

What is the Internet of Everything (IOT)

• where everything is interconnected, such as people to machine (P2M).​

• network of physical objects, with a unique identifier, combined with an embedded system of sensors, software and communication technologies.​

• Smart devices

• An interconnected network of computers and machine for a specific purpose

​ ​​ ​ ​ (a)   connections are made when information is transferred from one person to another.

​ ​ (b)   direct communication between devices; sensor data is transmitted between devices and a program helps interpret and make decisions.​

​ ​ (c)   where information is transferred between a device and a person to help the person make a decision; the action the person then takes forms a feedback loop.​
