Tag: Operating System

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Examples of popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. So-called mobile operating systems include Android and iOS. Other classes of operating systems, such as real-time (RTOS), also exist.

BrandPost: Programming the Network: It’s a Whole New World

With Open IOS XE, Cisco is changing the game Old-school network engineers probably remember the Cisco 2500-series router.
It ran a slow Motorola 68000 CPU, the monolithic IOS operating system, and did one thing only:  route packets.Routers and switches have certainly sped up since then, and the operating system has been modernized, but networking hasn't changed much otherwise. We still use CLI and SNMP to manage our networks the same way we did in the 1990s.With Open IOS XE, however, Cisco is changing the game. We now support powerful programmable interfaces like NETCONF and YANG. We can easily on-board devices without tedious manual configuration, and we can host Python scripts and applications all directly on the box.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Apple releases iOS 11: What developers need to...

As Apple laid the groundwork for iOS 11 at WWDC this week, developers approached the start line of a long summer ahead.

The preview of iOS 11 sets the bar high for development teams across the board, and is pushing iOS developers to experiment with emerging technologies like artificial intelligence (AI) and augmented reality (AR) unlike ever before.We have three months to go before the new operating system hits the market.

To get the development process off on the right foot, letrsquo;s break down some of the biggest changes and challenges with iOS 11 that are putting devops teams to the test. Popular devices dropped from iOS 11 With the introduction of iOS 11, addressing changes in supported devices is a crucial first step. With the upcoming launch of iPhone 8, iPhone 8 Plus, and iPad Pro 10.5, these new devices will push the iPhone 5, iPhone 5C, and iPad Mini off the list of iOS 11-supported devices.To read this article in full or to leave a comment, please click here
