Unix Operating System Unix is a proprietary software operating system. Unix is mainly used in Server Systems, Mainframes, and High-End Computers. The root is followed by its subdirectories, as in an inverted tree, and ends with the file. Since it is so fluid and agile, Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablets, and video game consoles, to mainframes and supercomputers. Unix primarily uses Command Line Interface. Linux is basically the name of the Kernel and was developed in 1991. Hence, cannot be installed on every other machine.

If you need to repeat a command, you can use the up and down arrow keys to scroll up and down the list or enter history for a list of previous commands. Linux is an open source operating system based on Unix. Linux is highly scalable and supports a really large set of file systems. Multitasking: Linux has the ability to handle more than one job at a time, say for example you have executed a command for sorting for a huge list and simultaneously typing in a notepad. However, the authority to implement the development lies with the founder of Linux — Linus Torvalds who has been releasing updates to its Kernels. There are comparatively more distributions or versions of Linux operating systems.

There are also several other differences between them, but this can occur even among different Linux distributions.

All the terminals are then connected to the main Linux Server or Host Machine, whose resources and connected peripheral devices such as printer, can be used. So is Illumos and other OpenSolaris forks. Communication: Linux has an excellent feature for communicating with the fellow users, it can be within the network of a single main computer, or between two or more such computer networks. It interfaces directly with the computer hardware and is responsible for allocating and managing the resouces available to programs. Unix has a rigid requirement of the Hardware.
