A low-cost, credit-card-sized computer, Raspberry Pi was created in the UK by the Raspberry Pi Foundation. It was created as a teaching tool to help instructors educate students about computer science and programming, but it has since gained popularity as a go-to option for creating a variety of electronic projects and Internet of Things (IoT) applications.

The Raspberry Pi is a [single-board computer](https://www.baesystems.com/en-us/definition/what-are-single-board-computers) (SBC), meaning it consists of all the components necessary to function as a computer. It features a processor, memory, and input/output (I/O) interface, and it may be used as a desktop computer when attached to a display, keyboard, and mouse. With the operating system and programs loaded onto a microSD card, it can also be used as a standalone computer.

The board comes at a low price which is one of its distinguishing qualities, making it an economical choice for hobbyists and students. With a variety of software development tools and frameworks that make it simple to design and deliver projects as it is incredibly adaptive and versatile in nature. 

**What is Raspberry Pi 4**

The Raspberry Pi 4 is a single-board computer (SBC) that builds upon the success of previous models, offering improved performance and a range of new features.

Some key features of the Raspberry Pi 4 include:

1: Better performance

With a quad-core ARM Cortex-A72 CPU operating at 1.5 GHz, the Raspberry Pi 4 boasts a more powerful processor than earlier models. It can handle more difficult jobs because to its up to 8 GB of RAM.

2: Improved multimedia support

With a video core VI GPU that supports hardware-accelerated video decoding and encoding, the board offers better support for multimedia applications. It can support dual screens because it also includes a full-size HDMI port and two tiny HDMI connections.

3: Advanced connectivity

Better connectivity choices are available on the device, including dual-band Wi-Fi, Bluetooth 5.0, and gigabit Ethernet. It can connect to a variety of devices thanks to its two USB 3.0 connectors and two USB 2.0 ports.

4: Improved power management

The board carries improved power management, with a more efficient power supply and support for Power over Ethernet (PoE).
 
**Raspberry pi in IoT**

A robust and adaptable single-board computer, the [Raspberry Pi 4 in IoT](https://www.theengineeringprojects.com/2021/03/what-is-raspberry-pi-4-pinout-specs-projects-datasheet.html) is ideal for Internet of Things (IoT) projects and research. It is the right match for developing and testing IoT prototypes and apps because of its improved performance and better connectivity.

The Raspberry Pi 4's inexpensive price makes it an accessible alternative for researchers and students, which is one of its main benefits for IoT research. With a variety of software development tools and frameworks that make it simple to create and deploy IoT projects, it is also extremely flexible and scalable.

The dual-band Wi-Fi and Bluetooth 5.0 provide better connectivity options on the board making it simple to connect to other devices and the internet. This way it can send and receive data and communicate with other devices. Thus, it can be used to create IoT systems with lots of connected devices.

The board is a good choice for use in Internet of Things (IoT) projects that call for low-power operation or that must be powered remotely because of its better power management and support for Power over Ethernet (PoE).
