What is Linux
Currently you use Linux in any kind of device, computer, smartphone, electronics and other types of things. Now you know what Linux is. In fact, Linux is a very popular and famous operating system (operating system) which is used in gadgets, cars, smartphone, super computer, home application, etc. In one word, it will not be wrong to say that Linux operating system is used almost everywhere. Again , many of us are using Linux OS everyday but we don't understand it well. Remember, the Linux operating system has been around for a long time. It has been in use for over 30 years. Since then, Linux is being used in various types of devices and computers. So, let's learn more about the Linux operating system (Linux OS) from below.
What is Linux? (What is Linux)
An operating system (OS) plays an important role in making a computer device work from scratch. operation system is a system software whose job is to manage the hardware and software components of the computer. After the operating system is loaded into the computer memory, the computer gives instructions based on the available information or data. Just like Windows and Mac operating systems, Linux OS is basically built on Linux kernel. Linux is an open source software, so it is a completely free operating system that anyone can use very easily. Anyone can modify Linux coding from the Internet for personal and business use. Remember, a famous version of Unix operating system. Since Linux is open source, many developers can customize it to their liking. Originally, its operating system was developed for personal computers. Later, it was used in other platforms such as smartphones, smartphone TVs, gaming consoles and other types of operating systems. However, Linux OS was used more in supercomputers.
Who owns Linux?
As I said earlier, Linux is an open source license, so anyone can download it from the internet and use it for free. However, its trademark remains with owner Linus Torvalds. Linus Torvalds is a software engineer. Moreover, the copyright of the source code of Linux OS is held by several authors. Therefore, Linux is collectively kept under the GPLv2 license.
History of Linux | History of Linux
Linus Torvalds created Linux in 1991. He was a Finnish American Software Engineer. It has been only 21 years since he wrote his master thesis on Linux when he was a student. From that time to this time, the Linux kernel continues to evolve. In 1991, when he was studying computer science, he started working on a project that later became the Linux kernel. Remember, when Linus Torvalds first created Linux, it was called Freax, but it was later renamed to Linux.
Difference between Linux and Windows
1. Linux is an open source operating system that anyone can use for free. But Windows is not an open source operating system, so you have to buy a license to use it
2. There are three types of user accounts in Windows: administrator, standard, guest. But in case of Linux there are root, regular and service accounts.
3. Windows operating system is only for single user, but Linux OS supports multi user.
4. Linux is more secure than Windows. Because there is an opportunity for virus to attack.
5. Windows OS is widely used in personal computers. However, developers, programmers, coders and government organizations use Linux.
6. Due to the need for coding, it becomes difficult for a common person to use Linux. But in the case of Windows, coding is not required.
7. Windows has separate drives to accommodate lots of folders. But no drive is shown in Linux.
Features of Linux operating system
1. Open Source – Linux source code is freely available. It is a community based development project. Working with multiple teams enhances the capabilities of the Linux operating system.
2. Portable – Portable means a special type of software through which all types of hardware can work equally.
3. Multiprogramming – Linux is a multiprogramming system where multiple applications can run together.
4. Security – Linux provides very good security to its users. For example, providing password protection, encryption of data in certain files.
5. Shell – Linux has a special interpreter program, through which the commands of the operating system can be executed. Through it, various types of operations are possible. For example, functions that can be called from application programs.
6. Multi User – Linux is a multi user system which means different systems like memory, RAM, application programs.
ROMs can be accessed simultaneously by multiple users.
7. Hierarchical File System – Linux provides a standard file structure where system files / user files can be organized very easily.
