The Raspberry Pi (often shortened to RPi or RasPi) is a small, budget-friendly single-board computer designed for use in educational settings. Its dimensions make it portable yet powerful enough to run the Linux operating system and its derivatives.
With the advent of Windows 10 IoT, users can now enjoy the full power of Windows on their Raspberry Pi as well!
Since its inception, the Raspberry Pi has been sought after by many computer enthusiasts and creators, and it was once hard to find a “Pie”. Regardless of its “petite” appearance, the inner “core” is very powerful, and it has all functions such as video and audio. It can be said that “although the sparrow is small, it has all internal organs.”
What is a Raspberry Pi?
The Raspberry Pi is developed by the “Raspberry Pi Charitable Foundation” registered in the UK, with Eben Upton as the project leader. In March 2012, Eben Upton of the University of Cambridge officially launched the world’s smallest desktop computer, also known as a card computer, which is only the size of a credit card but has all the basic functions of a computer. This is the Raspberry Pi computer board. The Chinese translation is “Raspberry Pi”.
In 2006, the early concept of Raspberry Pi was based on Atmel’s ATmega644 single-chip microcomputer. The first batch of 10,000 “units” of Raspberry Pi “boards” were manufactured by manufacturers in Taiwan and mainland China.
It is a microcomputer motherboard based on ARM, with SD/MicroSD card as the memory hard drive, there are 1/2/4 USB ports and a 10/100 Ethernet port around the cardboard (Type A has no network port), which can be connected to a Keyboard, mouse, and network cable, as well as a TV output interface for video analog signals and an HDMI high-definition video output interface, all the above components are integrated on a motherboard that is only slightly larger than a credit card.
With all the basic functions of a PC, only need to connect to the TV And keyboard, you can perform functions such as spreadsheets, word processing, playing games, playing high-definition video, and many other functions. The Raspberry Pi B type only provides the computer board, without memory, power supply, keyboard, case, or connection.
There are also developers trying to install Windows 10 ARM version and Windows 11 ARM version on Raspberry Pi.
How does Raspberry Pi work?
Raspberry Pi is a programmable device. It comes with all the critical features of the motherboard in an average computer but without peripherals or internal storage. To set up the Raspberry computer, you will need an SD card inserted into the provided space. The SD card should have the operating system installed and is required for the computer to boot.
Raspberry computers are compatible with Linux OS. This reduces the amount of memory needed and creates an environment for diversity.
After setting up the OS, one can connect Raspberry Pi to output devices like touchscreen monitor or a High-Definition Multimedia Interface (HDMI) television. Input units like mice or keyboards should also be connected.
This minicomputer’s exact use and applications depend on the buyer and can cover many functions.
