Understanding and familiarity with the operating system

Definitions and concepts of computer operating systems:

The operating system is the program to manage computer hardware and software resources, but also the core and cornerstone of the computer system. The operating system is tasked with basic tasks such as managing and configuring memory, prioritizing system resource supply and demand, controlling input and output devices, operating networks, and managing file systems. Operating system is to manage all the hardware resources of computer system including software resources and data resources, control program operation, improve human-machine interface, and support other application software, so as to maximize the function of all resources of computer system and provide users with convenient, effective and friendly service interface. The operating system is a large management control program, which roughly includes 5 management functions: Process and processor management, job management, storage management, device management, file management.

Classification of operating systems:

There are DOS, OS/2, UNIX, Xenix, LINUX, Windows, NetWare and so on, which are common on microcomputer. But all operating systems have four basic features of concurrency, sharing, virtualization, and uncertainty. Computer system is responsible for supporting the application operating environment and user operating environment of the system software, but also the core and cornerstone of the computer system. Its responsibilities often include direct monitoring of hardware, management of various computing resources (such as memory, processor time, etc.), and the provision of application-oriented services such as job management.

Advantages of Linux:

1 Safe-There are virtually no problems such as viruses, spyware, rogue software, and so on.

2 Easy to maintain-forget about scanning viruses, defragmenting the disk, cleaning up the registry, and frequent requests for reboots, and so on.

3 Stable-The gnu/linux is very stable. Although individual applications may crash, the crash of the operating system itself is very rare. (In fact, some non-official packaging procedures are more unstable)

4 software Free/Open source-you can use the software at your own discretion. If you want, you can even freely learn the program source code, modify the program and any sharing program without being subject to the so-called User License agreement. (Of course under the terms of the GPL or other open Source license agreement)

The 5 open standards-Gnu/linux and the applications running on them, most of which are compliant with open standards, make it possible to seamlessly compatible with other platforms and help you avoid being subject to some vendor restrictions.

6 Community-Gnu/linux has been described as "World wide team sport", supported by excellent programmers around the globe.

7 Low cost-most gnu/linux distributions are free to download and have plenty of free program support. In addition, most gun/linux have low hardware requirements, which means that you do not need to upgrade your hardware frequently.

Disadvantages of Linux:

Missing apps and games-you'll lose some familiar apps, typically such as Microsoft Office, Adobe Photoshop, and other popular big mainstream games. Dual-system startup, wine, or virtual opportunities provide a partial solution to this problem. Of course, there are many optional high-quality gnu/linux native software is worth using, the following will introduce the application software under various gnu/linux.

Lack of hardware support-the vast majority of hardware is supported, but not all – it is recommended that you study compatibility before purchasing new hardware components-the more new and less distributed components, the greater the risk of the problem.

Advantages of Windows:

Windows is now the mainstream operating system, because his interface is good, easy to get started, so the use of more people, but also based on his research is more. Applications developed by many software vendors are also developed in Windows-based environments.

2 current compatibility, entertainment, stability, security are quite good, is the daily entertainment office of choice.
