What is Raspberry Pi?

What is Raspberry Pi

Many people have heard the name, Raspberry Pi. I was interested in this recently and I decided to write down some of the things I found out for everyone.

 

The Raspberry Pi is a single-board computer, a small-sized computer with all the components needed to operate a single board. Raspberry Pi is small in size but the performances are high.

 

These computers are developed by the Raspberry Pi Foundation in the UK. The Raspberry Pi computers were designed to help children in developing and poor countries who cannot afford a computer. But now it is very popular among the poor and rich. The reason is we can do a lot of works using this Raspberry Pi.

The company only provides you the Raspberry Pi, it means the small circuit board and it’s up to you to turn this circuit board into a computer!

 

Raspberry Pi computers have already been introduced in five major versions. They are,

Raspberry Pi 2

Raspberry Pi Zero

Raspberry Pi 3

Raspberry Pi 4

 

These can be subdivided into more subsets as in their features. The latest of these is the Raspberry Pi 4. The Raspberry Pi 4 also comes in that four subsets. It comes with 1GB RAM, 2GB RAM, 4GB RAM, and 8GB RAM.

If you want to buy this Raspberry Pi, you can’t buy it directly from the Raspberry Pi Foundation. It has to be done through a reseller. In Sri Lanka, the latest 4GB edition can be purchased for less than Rs. 15,000.

 

The best part is, we can’t use it when we buy it. Since this is a DIY (Do It Yourself) computer, you will need to purchase a few accessories. And it’s up to you to connect them.

 

To activate the Raspberry Pi 4, we need more than the Raspberry Pi circuit board, those are,

 

USB-C Power Supply cable

Hard disk is a microSD card like 32GB.

Micro HDMI cable if you want to connect to a monitor (if you have a laptop, you can use it by sharing the desktop over the network. A monitor is not required.)

Heat Sinks or Cooling Fans

 

Basic things are like that.

To run Raspberry Pi Device you need the Raspberry Pi operating system (OS – formerly known as Raspbian OS) It’s a Linux-based operating system.

 

You can install this OS on your Raspberry Pi. Or even an OS like Ubuntu, you can install it.

 

Once you have all the hardware assembled and installed the software, you can use your Raspberry Pi computer. This is a very powerful computer.

 

This is an excellent tool for not only poor children but also for those who want to make their own customized computer. They also provide you with a magazine on various projects you can do with this device as well as many more. Its name is MagPi.

 

 

You can get more information about it online. This is a great opportunity for the people who are willing to discover new things and the people who are love DIY projects.
