What Is Raspberry pi ?

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

The Raspberry Pi Components

raspberryHere are the various components on the Raspberry Pi board:

  • ARM CPU/GPU — This is a Broadcom BCM2835 System on a Chip (SoC) that’s made up of an ARM central processing unit (CPU) and a Videocore 4 graphics processing unit (GPU). The CPU handles all the computations that make a computer work (taking input, doing calculations and producing output), and the GPU handles graphics output.

  • GPIO — These are exposed general-purpose input/output connection points that will allow the real hardware hobbyists the opportunity to tinker.

  • RCA — An RCA jack allows connection of analog TVs and other similar output devices.

  • Audio out — This is a standard 3.55-millimeter jack for connection of audio output devices such as headphones or speakers. There is no audio in.

  • LEDs — Light-emitting diodes, for all of your indicator light needs.

  • USB — This is a common connection port for peripheral devices of all types (including your mouse and keyboard). Model A has one, and Model B has two. You can use a USB hub to expand the number of ports or plug your mouse into your keyboard if it has its own USB port.

  • HDMI — This connector allows you to hook up a high-definition television or other compatible device using an HDMI cable.

  • Power — This is a 5v Micro USB power connector into which you can plug your compatible power supply.

  • SD cardslot — This is a full-sized SD card slot. An SD card with an operating system (OS) installed is required for booting the device. They are available for purchase from the manufacturers, but you can also download an OS and save it to the card yourself if you have a Linux machine and the wherewithal.

  • Ethernet — This connector allows for wired network access and is only available on the Model B.

Many of the features that are missing, such as Wifi and audio in, can be added using the USB port(s) or a USB hub as needed

more Raspberry Pi Device Details

The Raspberry Pi measures roughly 3.4 inches by 2.1 inches (8.6 centimeters by 5.3 centimeters), but it is pretty powerful for such a small device. This was made possible by the ready availability of inexpensive and tiny processors for mobile devices, which need to pack a decent amount of processing and multimedia capability into a small shell with the ability to stay relatively cool and not suck power too quickly.

The foundation picked a chip with ARM architecture for this reason (a processor architecture commonly used for mobile phones and similar devices).

Like many of the earliest home computers, the device comes without peripherals or internal storage space, and the user will have to attach input, output and storage peripherals. At a minimum, you’ll need a television or monitor for output, a keyboard (and possibly a mouse) for input, an SD card on which to house the OS and store data, a power supply and any necessary cables. You can add an external hard drive for additional storage, but the SD card will still be necessary, as the OS will boot from SD by default.

The compatible operating systems for the device are all Linux distributions. Linux was chosen at least partially for its low memory overhead, making it possible to run a fully functional OS on such a simple device that’s devoid of built-in permanent storage. Linux is also generally free and has great potential as a CS learning tool..

    Hi there! This post could not be written any better!

    Reading through this article reminds me of my previous roommate!
    He constantly kept preaching about this. I’ll forward this post to him.

    Fairly certain he’ll have a very good read.
    I appreciate you for sharing!
