When it comes to budget-friendly, compact computing, the Raspberry Pi is a game-changer. Designed to kindle a passion for computer science, this credit-card sized marvel boasts versatility that intrigues everyone from school kids to computer scientists.
A Brief History of the Raspberry Pi
Hailing from the UK, the Raspberry Pi Foundation birthed the Raspberry Pi to bolster computer science education. From its launch in 2012 to February 2022, they’ve sold a staggering 46 million units. While its initial cost was around $35, due to supply chain challenges and chip shortages, the price saw a hike, sometimes exceeding $150.
Raspberry Pi as a Desktop
While it mimics the functionality of a conventional computer—possessing RAM, a processor, USB ports, and HDMI connections—it stands out because of its adaptability. Whether you’re gaming, coding, or just browsing, the Raspberry Pi delivers. It’s often depicted as a mini desktop computer, exemplified by setups like the Raspberry Pi 3 desktop configuration.
Going Headless with Raspberry Pi
For those preferring a leaner setup, the Raspberry Pi can operate without a monitor, mouse, or keyboard. Through SSH, users can command the device remotely using Linux terminal commands, showcasing its ‘headless’ capability.
