There are lots of mainstream versions available for the Linux operating system that are available free of cost. The Linux operating system helps you to access many free applications and lots of information that can be viewed from the web and from online platforms like discussion forums. These web pages are specifically designed to help the user by making him more comfortable with the interface and applications which he may otherwise face problems with.

Linux can be installed into a number of computers and can be put on a number of external devices. If you possess an SD card, a version of Linux can be installed onto it and it can be run from there; or it can also be installed into the computer.

Before you go ahead, it is important to learn what is understood by SD or Secure Digital cards. An SD is a non-volatile memory card that has been developed for use in portable devices like digital cameras, handheld computers, digital camcorders, PDAs, netbook computers, mobile phones, media players, video game consoles and GPS receivers. Though they can usually accommodate up to 4 GB of data, standard SD cards have an official maximum capacity of 2 GB. These SD cards have proved to be very popular among the paying public, who have started switching from older devices to those containing these cards. All the SD cards come in similar shapes, which often cause confusion among people. Although they are based on the older MMC (MultiMediaCard) format, there are a number of differences between the two. Firstly, the SD card is asymmetrically shaped in order to not be inserted upside down, whereas the MMC would go in almost all the way but not make contact if it is inverted. Physically, most SD cards are thicker than the MMCs and most of them do not fit into the thinner MMC slots.

Instructions to embed Linux on SD cards

Step 1: First of all, you can download UNetbootin from the link http://unetbootin.sourceforge.net/. It is the only application that allows a user to choose from more than 40 Linux distributions and then install them to an external device.

Step 2: Then you need to launch UNetbootin and insert your SD Card into the system. Next to the ‘Distributions’ option, there’s a drop down menu that you have to click on and then choose the version that you want on your card. Select your SD card after clicking on ‘Type’.

Step 3: Click on OK and the distribution that you had chosen would be downloaded and installed on your SD card. It should be noted that there are many distributions which may take more than an hour to download if you have a slow Internet connection; and many of these distributions take up to 700 MB of space.

Therefore, it can be seen that it is usually not a difficult procedure to embed Linux on SD cards if you follow the above instructions properly.
