Is linux better or unix

Linux is based on UNIX!

Difference Between Linux vs Unix:

Some PCs have similar implementations to UNIX and Linux. Almost all commercial UNIX versions support the same software, programming environment, and network features. However, there are still many differences between the commercial versions of Linux and Unix.

The range of hardware supported by Linux is not the same as that of commercial Unix. Generally speaking, commercial UNIX supports more hardware, but Linux supports more hardware. What stands out is that Linux is at least as stable as commercial Unix.

For many users, the most important factor is. Linux is free software that users can use from the Internet online**. If you don't have easy access to the Internet, you can get Linux disks or CD-ROMs by mail order very cheaply.

Of course, you can also get it directly from friends. The value of commercial UNIX should not be devalued. In addition to the software itself, users also pay for documentation, after-sales support, and premiums.

For larger organizations, these are important, but PC users may not benefit from them. Many commercial companies and universities have found that running Linux on an inexpensive PC in the lab is better than running commercial Unix on a workstation. Linux can provide the functionality of a workstation on a PC, which is a fraction of the size of a workstation.

There are also some cheap Unix for PCs, the most famous of which is 386BSD. In many ways, the 386BSD package is compatible with Linux, but Linux is better suited to the user's needs. Most notably, Linux development is open and any volunteer can contribute to the development process.

In contrast, 386BSD was developed by a closed team. It is in this way that there are serious conceptual and design differences between the two products: the goal of Linux is to develop a complete UNIX system from the ground up; The goal of the 386BSD is to modify the existing BSD to fit the 80386 system.

The relationship between UNIX and Linux is more appropriate to use the term parent-child relationship, and we will also find that Linux has many similarities with UNIX when learning, which can also be understood as if you are already proficient in Linux, and then it will be very easy to learn to use UNIX.

The difference between the two:

1. Unix systems are mostly matched with hardware, which can be understood as that most UNIX systems such as AIX and HP-UX cannot be installed on x86 servers and personal computers, while Linux runs on a variety of hardware platforms;

2. UNIX is commercial software and is charged, Linux is open source software, which is free, and the source is also public.

To summarize the difference between the two, Linux is a UNIX-like operating system, UNIX was born earlier than Linux, the original intention of Linux is to replace UNIX, and make some optimizations in functions and user experience, so Linux imitates UNIX, but there is no plagiarism, and it is for this reason that Linux is very similar to UNIX in appearance and interaction.

Why is Linux so popular and used by developers? There are two main points.

1. Linux is open source software, users can get its source and use it without paying a fee, and can also make necessary modifications to it according to their own needs and use it for free;

2. It has all the features of UNIX, and anyone who uses the UNIX operating system or wants to learn the UNIX operating system can benefit from Linux.

1. The essence is different: Linux is the first free software developed from the source, and users have a high degree of autonomy for the former, and the actual development is in a completely open environment; UNIX is a traditional commercial software that implements intellectual property protection for the source, and the user's development is completely in a black box, and only relevant developers can access the prototype of the product.

2. Different running platforms: Linux can run on a variety of hardware platforms without causing any major impact; Most of the UNIX systems are matched with hardware, 3. Whether the core is public is different: the core of Linux is free and free to use, and the core source is open; The core of UNIX is not public, in terms of hardware requirements, Linux is lower than UNIX, not as demanding as UNIX, and Linux is easier to master than UNIX in terms of installation.

1. The open-source nature is different

Linux is an open-source operating system that does not require payment and can be used; UNIX is a traditional commercial software that implements intellectual property protection for the source code, and the use of it requires a paid license.

2. Cross-platform is different

The Linux operating system has good cross-platform performance and can run on a variety of hardware platforms; The UNIX operating system has weak cross-platform performance and mostly needs to be used with hardware.

3. The visual interface is different

In addition to command-line operations, Linux also has a form management system; Unix is just a command-line system.

4. The hardware environment is different

The Linux operating system has lower hardware requirements and is easier to master. UNIX has strict hardware requirements and is more difficult to follow.

5. The user groups are different

Linux has a wide range of users and can be used by both individuals and businesses; UNIX's user base is relatively narrow, and most of them are used by large enterprises with high security requirements, such as banks and telecommunications departments, or used by UNIX hardware manufacturers, such as Sun.

Compared with the UNIX operating system, the Linux operating system is more popular with the majority of computer enthusiasts, the main reason is that the Linux operating system has all the functions of the UNIX operating system, and can realize all the UNIX features on ordinary PC computers, open source and free features, which is easier to use!

Different platforms: Linux can run on a variety of hardware platforms; The UNIX system is mostly matched with hardware. Whether the core is public or not is different:

The core of Linux is free and free to use, and the core source is open; The core of UNIX is not public, in terms of hardware requirements, Linux is lower than UNIX, not as demanding as UNIX, and Linux is easier to master than UNIX in terms of installation. <
