The disadvantages of peer-to-peer networking:
World Wide Networks (WAN)
The main example being the internet, is a network of networks that connects hundreds of millions of computers world-wide.
Radio frequency identification (RFIDs) tags
These can be placed in or on objects to track them or monitor sensors for many conditions.
Medium to Large Networks
These networks, such as those used by corporations and schools, can have many locations with hundreds or thousands of interconnected hosts.
Medical Devices
These such as pacemakers, insulin pumps, and hospital monitors provide users or medical professionals with direct feedback or alerts when vital signs are at specific levels.
Smart Glasses
They are a wearable computer in the form of glasses, such as Google Glass, contains a tiny screen that displays information to the wearer in a similar fashion to the Head-Up Display (HUD) of a fighter pilot. A small touch pad on the side allows the user to navigate menus while still being able to see through the smart glasses.

They filter the flow of data to enhance security.
They are the interface between humans and the communication network. & They originate the data that flows through the network.
Small Home Networks
They connect a few computers to each other and to the internet.
A Smart TV
This can be connected to the internet to access content without the need for TV service provider equipment. Also, a smart TV can allow a user to browse the web, compose email, or display video, audio, or photos stored on a computer.
A Smartwatch
This can connect to a smartphone to provide the user with alerts and messages. Additional functions, such as heart rate monitoring and counting steps, like a pedometer, can help people who are wearing the device to track their health.
Gaming Consoles
This can connect to the internet to download games and play with friends online.
(Connected) Sensors and Actuators
This can provide temperature, humidity, wind speed, barometric pressure, and soil moisture data. Actuators can then be automatically triggered based on current conditions. For example, a smart sensor can periodically send soil moisture data to a monitoring station. The monitoring station can then send a signal to an actuator to begin watering. The sensor will continue to send soil moisture data allowing the monitoring station to determine when to deactivate the actuator.
Observed data
This is captured by recording the actions of individuals, such as location data when using cell phones.
Volunteered data
This is created and explicitly shared by individuals, such as social network profiles. This type of data might include video files, pictures, text or audio files.
Inferred data
This is data such as a credit score, which is based on analysis of volunteered or observed data.
Bandwidth
This is the capacity of a medium to carry data. Digital bandwidth measures the amount of data that can flow from one place to another in a given amount of time and is typically measured in the number of bits that (theoretically) can be sent across the media in a second.
Throughput
This is the measure of the transfer of bits across the media over a given period of time. However, due to a number of factors, throughput does not usually match the specified bandwidth.
