What is Raspberry Pi?

The Raspberry Pi is a 35$ personal computer chip size of you’re credit card. No Kidding Raspberry Pi with Pi Pronounced pie and development team literally used credit card as a template when they designed the Pi’s printed circuit board (PCB).

Historically, Computer science curricula both the K-12 and even collegiate levels-if there is any curricula at all-tend to focus more on theory than on practical application of computing concepts, Raspberry Pi in 2006 as a way to make a computer science more accessible to students.

What is Pi?


Many consider the Raspberry Pi to be an ideal platform for teaching both kids and adults how computer science works because it requires minimal investment. Any interested individual can learn not only how to program computer software and work directly with computer hardware.

If any program of coding goes wrong student will have to pay 35$ to buy new Raspberry Pi, Now Raspberry Zero is only 5$

To be sure, the Pi’s fan base isn’t entirely academic. There exists a devoted following of do-it-yourselfers and hardware hackers who employ the Pi as a intergral part of their hardware and software hacking experiments.


Why Raspberry Pi Name?

The Name Raspberry Pi dose indeed have a colorful history. Raspberry Pays homage to the fruit names that played a part in early-80s micro computing: Apple Macintosh, Tangerine Microton 65, Apricot PC-the list goes on.

Pi Actually references not the standard number but the Python programming language. Eben and the rest of the Foundation originally thought that Python would be the sold programming language supported by their tiny personal computer. As you learn later, Raspi allow enthusiast to write programs using a large variety of programming languages.


Raspberry Pi Open Source?

It is important Question to have answered before asking whether or not Raspberry Pi is open Source : ” What dose open source mean, and why should i care? ”

Open source refers to hardware and/or software that is manufactured and given away free of charge with all intellectual property rights intact.

For Comparison purpose, think of Microsoft Windows and Apple Mac OS X desktop operating systems. As Probably know, these OS Platforms are proprietary, which means the general public cannot reverse-engineer the software to examine it’s underlying source code.


Hardware of Raspberry Pi?

Well, if you’re received your Raspberry Pi, you might have been surprised to see that the Foundation doesn’t give you case, That’s right for $35 or 5$ you receive the Raspberry pi Model B Board and nothing else.

This is actually good news because it forces us to take long, hard look at the befuddling mass of wires, components, solder joints, and doo-dads that reside on the Pi board.

Traces: These are tiny copper wires that are embedded into the PCB substrate and that form the backbone of the circuit.

Vias: These are small metal rings that serve and interconnect for boards that have multiple layers of traces.

Resistors: These are components that resist the flow of electrical current. Resistors are Labeled RX on PCB, with X denoting a discrete number identifying a specific capacitor.

Capacitors: These are components that temporarily store electrical charge. Capacitors are labeled CX on PCB.

Diodes: These are components that force electrical current of flow in a particular direction.

Transistors:  These are three terminal components that act as electrically controlled switches.

ICs: These are self-contained modules that run a circuit of their own in addition to interacting with circuits on the PCB. The Broadcom SoC is itself an integrated circuit module.
