 WHAT IS DNS & IP

  In networking, packets are a smaller segments of large messages.  When a message is sent over the internet, it is divided into packets.  In other words, packets are small amount of data that are sent over the network.  In accordance to a real life happening, the packets have a source and destination as well as content that are transferred from one place to another. To be more significant, the network breaks a messaged that is emailed into small size in bytes.  The packets carry the data in the protocols that can be found on the internet: Transmission Control Protocol/Internet Protocol (TCP/IP). A Packet has a header and a payload.  The header keeps overhead information about the packet, the service and other transmission related data.  Each packet header contains proper protocols, originating address (The IP address of your computer), the destination address (The IP address to where you are sending the email to) and the packet number (1, 2, 3 o...

In simple terms the IoT is a connection of :  networked sensors, actuators, and smart devices that collect and share data.   Packet Tracer 7 contains many new features to support the IoT.  This includes the addition of IoT devices that can be configured to react to certain environmental values such as sun, wind, rain, and humidity. These devices can be configured to take actions based on the changing environmental values, such as turning on lights or closing garage doors.  The next parts of learning will include instructions to locate the IoT devices, to connect them to your network, to configure and modify scripts to make them function, and to control these devices remotely. Packet Tracer provides everything you need to create simulated smart homes, smart cities, and smart factories. CONFIGURE IoT DEVICES USING PACKET TRACER Packet Tracer has a wide variety of sensors and smart devices that will allow you to design smart homes, smart cities, smart factorie...
