What is Raspberry Pi ?
The Raspberry Pi is a single-board ARM processor nanocomputer the size of a credit card designed by professors in the University of Cambridge’s IT department as part of the Raspberry Pi Foundation.
WHAT IS THE RASPBERRY PI 4?
The Raspberry Pi 4 Model B is the latest version of the low-cost Raspberry Pi computer. The Pi isn't like your typical device; in its cheapest form it doesn't have a case, and is simply a credit-card sized electronic board -- of the type you might find inside a PC or laptop, but much smaller.
What is the Raspberry Pi 4 features?
This product’s key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, up to 8GB of RAM, dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on).

- Advantages and disadvantages of Raspberry Pi?
- Advantages of Raspberry Pi:
This microcomputer is useful for small business that run on a lower budget to use their product or to invent new technology that embeds the product. Small business owners can use it to automate any small task, i.e.; such as using the Pi to run a website or use it as a small database and media server.
The product does not require user to have extensive programming experience since it is aimed for the younger generation to learn about programming. Python, the programming language i.e.; Pi uses, is a smaller amount complex than other languages available. It has better code readability and allows the user to type concepts using fewer number of lines. Python also has a automatic memory management function.
The product gives a lot of room to experiment and turn it into something else i.e.; entirely different. The SD cards on the board can be easily switched, i.e.; which allows to change the functions of the device without spending a lot of time re-installing the software.
The Raspberry Pi is perfect for adaptive technology and it is able to display images or play videos i.e.; at high-definition resolution to building systems such as prototyping embedded systems. This product makes it possible to build complex and effective at a cheaper price.
The product is efficient and i.e.; provides an ethical alternative to small businesses. This small card sized product i.e.; makes it easy to recycle and does not release as much carbon dioxide emissions into the environment, i.e.; unlike big servers that need lots of energy and extensive cooling systems.
Disadvantages of Raspberry Pi:
- It does not replace the computer, and the processor is not as fast. It is a time consuming to download and install software i.e.; unable to do any complex multitasking.
- Not compatible with the other operating systems such as Windows.
- This is fit for those who want a gadget that they can tailor to their own needs and tastes, i.e.; not for those that just wants to urge a job done fast. Business owners need to consider the extra hassle if is worth it.
- This product not be useful for bigger business that already have big servers, i.e.; which would already do everything that the Raspberry Pi does. So, it would not be worth and it take time to get to put it together.
