What Is Sensor?

Personal area networkA personal area network is a computer network used for communication among computers and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and even video game consoles. A wired PAN is usually constructed with USB and FireWire connections while technologies such as Bluetooth and infrared communication typically form a wireless PAN. Bridges and switches operate at the data link layer of the OSI model and bridge traffic between two or more network segments to form a single local network. If an unknown destination MAC is targeted, the device broadcasts the request to all ports except the source, and discovers the location from the reply. A computer network extends interpersonal communications by electronic means with various technologies, such as email, instant messaging, online chat, voice and video telephone calls, and video conferencing.

Maintenance costs can be positively impacted when IoT devices are used with sensors to keep business equipment running at peak efficiency. On-the-fly troubleshooting of office equipment catches problems before they impact staff and employees, saving the hassle and costs of large repairs. IoT refers to the way devices connect with one another within a network environment. These devices can operate any number of functions, from sensors in thermostats and factory machines to printers, TVs, and even refrigerators.

In this hyperconnected world, digital systems can record, monitor, and adjust each interaction between connected things. All of this applies in business as well, but the stakes are even higher. Connecting industrial machinery to IoT networks increases the potential risk of hackers discovering and attacking these devices. Industrial espionage or a destructive attack on critical infrastructure are both potential risks. That means businesses will need to make sure that these networks are isolated and protected, with data encryption with security of sensors, gateways and other components a necessity.

Transport plays an important part in economic growth and globalization, but most types cause air pollution and use large amounts of land. While it is heavily subsidized by governments, good planning of transport is essential to make traffic flow and restrain urban sprawl. The mobility of passengers and freight is fundamental to economic and social activities such as commuting, manufacturing, distributing goods, or supplying energy. Each movement has a purpose, an origin, a potential set of intermediate locations, and a destination. Mobility is supported and driven bytransport systems that are composed of infrastructures, modes, and terminals.
