"What Linux is" features of Linux

UNIX like can be said to be the current server type of operating system collectively.

Linux features freedom and open use and learning environment

The open architecture is very important to the scientific community.

Low equipment requirements

Linux supports the x86 architecture of personal computers.

Powerful and stable kernel function

Linux features are not lost to some large UNIX workstations.

Stand-alone jobs

Linux has recently been able to complete the service of all workstations or servers independently. such as Web Mail Proxy FTP, etc.

Linux has a low demand for hardware. Many people have little in-use parts handy, and these parts can be assembled to run Linux. Anyway, doing a workstation without using the screen (as long as the host can) so Linux is becoming more and more popular.

Advantages and disadvantages of Linux

① Stable System
Linux has inherited the UNIX stability and efficiency features. It is common for Linux-installed hosts to run continuously for more than a year without downtime.
② free or little fee
③ Quick fixes for security vulnerabilities
Get up-to-date security information at any time, and be more secure.
④ Multi- tasking multi-user
Different from Windows Linux supports multi-user. You can plan for different levels of users on a Linux host, and each user can log on to the system with varying working environments. In addition, you can allow different users to log on to the host at the same time to use the host's resources concurrently.
⑤ planning for users and user groups
In Linux machines, the properties of a file can be divided into readable and writable executable parameters to define the applicability of a file. In addition, these attributes can be divided into three categories, namely the file owner, the user group to which the file belongs, and other non-owner and user groups . this has a fairly good system confidentiality for projects or other project developers.
⑥ relatively non-resource-consuming systems
⑦ for embedded systems that require small kernel programs
Linux can fully drive the entire computer hardware and become a complete operating system with just hundreds of KB of code. So suitable for embedded systems.
⑧ integrated and diverse graphical user interface

Disadvantages

①linux need to use the command line terminal mode for system management. (Maximum limit of popularity)
② does not have a specific support vendor
insufficient support for ③ games
lack of support for ④ professional software

About authorizing open source open source

Open source software in the release of the source code is also released.
Open source usually has the following benefits
① generally open source software in the release of good quality.
② Open Source Spirit
③ More secure

Close source closed sources

Closed source is a common software selling method of commercial software (Copyright). But not all commercial software is charged.
