Your Freedom In Linux

The linux ecosystem made the world of technology more interesting more open to everyone. The push of open source acting as the catalyst here. We’re here for promoting the world of linux. We want make it simpler and easier for general usage.

In 1991 Linux Torvalds began a personal project to create a new operating system. On August 25, 1991 he announced the OS in a newsgroup. And the OS gained popularity in 1992. Gradually the OS became the Linux kernel. And history began to change. The Linux kernel powers billions of devices worldwide. From the servers to smartphones, many many systems uses the Linux Kernel at its core.

The Linux ecosystem is much more broad. However, whatever the linux based system is, Linux Kernel stands at the core. Basically the Kernel handles all the devices and manages the memory and CPU. And the rest is done by the programs. There are thousands of Linux distros out there to use. And the most popular is the Ubuntu. Do you know the Android OS also uses Linux Kernel to power the mobile device? Yes, thats true. Most of the today’s servers are powered by Linux Kernels. And developers use ubuntu and CentOS mostly for server.

Linux enables to use the device as customizable as possible. We can do and change every core features. We can edit the source code of everything in Linux ecosystem. And so, we can build whatever we like.
