Where To Buy Raspberry Pi 4?

What is a Raspberry Pi?

The Raspberry Pi is a small computer that can do lots of things. You plug it into a monitor and attach a keyboard and mouse. Raspberry Pi is the third best-selling computer brand in the world. The Raspberry Pi is a credit card–sized computer that plugs into your TV or display, and a keyboard and mouse. You can use it to learn coding and to build electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games. It also plays high-definition video. The Raspberry Pi is being used by adults and children all over the world to learn programming and digital making. You can learn how to set up and use your Raspberry Pi here.

The Internet of Things (IoT) is the network of things (physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators) connected through internet which enables these things to exchange data. This creates opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits, and reduced human exertions.

In simple terms we can say IoT is a system of things integrated with sensors, softwares, electronics which are connected to each other & can exchange data or Information with other connected devices.

Security and Privacy:Security is an essential pillar of the Internet and one that to be equally essential and the most significant challenge for the IoT. As Increase the number of connected devices increases the opportunity to exploit security vulnerabilities, as poorly designed IoT devices can expose user data to theft by leaving data streams inadequately protected.A latest research claims that by 2020, 25% of cyber attacks will target IoT devices.

Major security issues in iot have been raised that the IoT is being developed rapidly without appropriate consideration of the profound security challenges involved.Most of the technical security concerns are similar to those of conventional servers, workstations and smartphones. Security is the biggest concern in adopting Internet of things technology. As the Internet of things spreads widely, cyber attacks are likely to become an increasingly physical threat.The vulnerabilities include weak authentication (IoT devices are being used with default credentials), unencrypted messages sent between devices, lack of verification or encryption of software updates.One of the key drivers of the IoT is data. The success of the idea of connecting devices to make them more efficient is dependent upon access to and storage & processing of data. Companies working on the IoT collect data from multiple sources and store it for further processing.Lack of proper Reguation and standards will open up the possibility for for privacy and security dangers. IoT regulation depends on the country. Several standards for the IoT industry are actually being established relating to automobiles because most concerns arising from use of connected cars apply to healthcare devices as well. Lack of standards and documented best practices have a greater impact than just limiting the potential of IoT devices.These are because of still early days for IoT in government and unclear business models, despite strong value proposition.Without the right standards to guide and regulate manufacturers the developers may design products that operate in disruptive ways and If they are configured or designed poorly, these devices may have huge consequences on resources they connect.
