Cisco IOS is a monolithic operating system running directly on the hardware while IOS XE is a combination of a Linux kernel and a monolithic application (IOSd) that runs on top of this kernel.
For data center environments, Cisco Nexus switches (Ethernet) and Cisco MDS switches (Fibre Channel) both run Cisco NX-OS, also a Linux-based operating system.
IOS XE – runs on top of a Linux kernel. IOS XE and IOS share a lot of the same code, but IOS XR is considered to be a completely different code base. IOS XR – based on QNX a commercial Unix-like real-time operating system.
IOS (Internetwork Operating System) is a multitasking operating system used on most Cisco Systems routers and switches.
The Linux kernel can run on a variety of devices made by Apple, including devices where the unlocking of the bootloader is not possible with an official procedure, such as iPhones and iPads.
Users of Windows and macOS can communicate with an iOS device by using software provided by Apple, but Apple doesn't support Linux users.
Android, which is based on the Linux kernel, has become the dominant operating system for smartphones.
Popular Linux distributions include:LINUX MINT.MANJARO.DEBIAN.UBUNTU.ANTERGOS.SOLUS.FEDORA.ELEMENTARY OS.
iOS is a mobile operating system which is provided by Apple Incorporation. It is mainly designed for Apple mobile devices like iPhone and iPod Touch. It was earlier known as iPhone OS. It is a Unix-like operating systems which is based on Darwin(BSD) operating system.
Kernel 3.4: At the core of Cisco's Open NX-OS is a 64-bit Linux kernel based on version 3.4. This kernel provides a balance of features, maturity, and stability; and serves as a solid foundation for programmability and Linux-based management of a Cisco Nexus switch.
What Is Apple iOS Apple (AAPL) iOS is the operating system for iPhone, iPad, and other Apple mobile devices. Based on Mac OS, the operating system which runs Apple's line of Mac desktop and laptop computers, Apple iOS is designed for easy, seamless networking between a range of Apple products.

Linux is open source
Open source features are something that Apple will never offer. You can't even find this on more flexible operating systems like Windows. If you've never used an open-source OS (and if you're reading this article, I assume you haven't) it's hard to describe how much of a game-changer it can be.
Linux is more secure than other operating systems, it has developers from all over the world to review its code and make sure there are no bugs and backdoors.
While iOS apps are extremely popular, they can be developed on other platforms like Linux or Windows as well. Due to their open-source features, Linux versions are popular in app development. The best thing is that you can work on iOS development on Linux by using the right tools.
Linux and macOS are both great and share some Unix heritage. For example, both come with a similar command-line shell and have an identical file structure. All other differences stem from the fact that the Linux kernel is open-source, and anyone is free to modify it. Not sure which Linux distro to use
BSD OS is not based on Linux.
Today, there are over 600 active Linux distros.
Some of the most commonly used are Debian, Gentoo, Ubuntu, Linux Mint, Red Hat Enterprise Linux, CentOS, Fedora, Kali Linux, Arch Linux, and OpenSUSE, Linux distribution usage statistics show.
Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems.
macOS is a series of proprietary graphical operating systems which is provided by Apple Incorporation. It was earlier known as Mac OS X and later OS X. It is specifically designed for Apple mac computers. It is based on Unix operating system.
Nintendo Switch Linux OS is a first
What does this mean for gamers Not much, since it's a heavily customized version of Linux. Nintendo isn't the only company using Linux for its console OS: Sony uses a version of Free BSD for its PS4 operating system. Microsoft on the other hand, uses Windows on the Xbox One.
It also has one of the biggest open source communities around meaning you can find tools and examples for almost anything you would like to do. Most of Cisco's UC apps are built on Java and products that support plugins or embedded code (like UCCX or CVP) often use Java as the plugin or embeddedable language.
Both the Mac OS X and iOS evolved from an earlier Apple operating system, Darwin, based on BSD UNIX. iOS is a proprietary mobile operating system owned by Apple and it is only allowed to be installed in Apple equipment. The current version — iOS 7 — uses approximately 770 megabytes of the device's storage.
Objective C is an extension of the C programming language with object-oriented programming capabilities. This language was developed in the early 1980s. It is the language that was used to create OS X and iOS, plus their APIs.
Python Scripts Overview
Cisco provides a Python module that allows user's Python scripts to run IOS CLI commands on the host device.
