For a computer, if excellent hardware is its "body", then the system is its "soul". Users who have installed the operating system can use the computer to perform various operations.
For now, Windows is still the most used system in PCs. Of course, in addition to Windows, there are some other very good operating systems. Let’s take stock of the excellent operating systems currently on the market and talk about them. advantages and disadvantages of the system.
1. Windows series operating system
Microsoft Windows is a set of operating systems developed by Microsoft Corporation in the United States. The system versions range from the original Windows 1.0 to the well-known Windows 95, Windows 98, Windows ME, Windows 2000, Windows 2003, Windows XP, Windows Vista, Windows 7, and Windows 8. , Windows 8.1, Windows 10, constantly updated and maintained.
Advantages: The software is rich and easy to use, and it can be used smoothly after simple learning;
Disadvantages: greater risk of virus infection during use
Summary: Thanks to the ease of use of Windows, anyone can use it after simple learning. Windows system has become the system with the largest number of users in the world. It is widely used in various fields of daily work and life. Because of the huge user base, So the software that can be used is also the most, which is its biggest advantage.
However, the huge user base also brings hidden dangers to the Windows system. Most Trojan horses, viruses, and malicious software are aimed at Windows system users, so users are at a greater risk of being infected with viruses during use.
2. Linux operating system
Linux is a set of Unix-like operating systems that are free to use and spread freely. It is a POSIX and UNIX-based multi-user, multi-tasking, multi-threading and multi-CPU operating system. It can run major UNIX utility software, application programs and network protocols. It supports 32-bit and 64-bit hardware, and the Android system is developed based on Linux.
Advantages: Open source, system vulnerabilities are easier to be found and patched;
Cons: If you don't know Linux commands well, it's almost impossible to use the system.
Summary: Linux is an open-source free operating system. Because of the open-source nature, system vulnerabilities are easier to be discovered and repaired. In addition, because the original human-computer interaction interface of Linux is the command line, if users are not familiar with Linux commands, it is almost impossible to use this system at all. Because it is too professional, Linux is often used as a variety of server operating systems.
It can be said that the basic idea of Linux has two points: first, everything is a file; second, each software has a definite purpose. The first one is that everything in the system boils down to a file, including commands, hardware and software devices, operating systems, processes, etc. For the operating system kernel, they are all regarded as files with their own characteristics or types .
3. UNIX operating system
The UNIX operating system (Eunice) is a powerful multi-user and multi-tasking operating system that supports multiple processor architectures and belongs to the time-sharing operating system. It was first established by Ken Thompson, Dennis Ritchie and Douglas McIlroy in AT&T's Bell Experiment in 1969. room development. Currently its trademark rights are owned by the International Open Standards Organization. Only UNIX systems that conform to the single UNIX specification can use the name UNIX, otherwise it can only be called UNIX-like (UNIX-like).
Advantages: Strong portability, suitable for a variety of hardware platforms. The security, stability and performance are higher than Linux, but a professional hardware platform is required;
Disadvantages: high threshold.
Summary: UNIX is one of the earliest operating systems. The original Linux was written by imitation minix. UNIX has matured and requires a lot of professional knowledge to operate. In addition, the UNIX system has strong portability. Suitable for a variety of hardware platforms. In addition, UNIX has a good user interface; the program interface provides C language and related library functions and system calls, and the command interface is SHELL. The output device is higher than Linux in terms of security, stability and performance, but requires a professional hardware platform and has a high threshold.
4. Apple (OS X) operating system
The Mac system is a graphical operating system based on the Unix kernel. Generally, the operating system cannot be installed on ordinary PCs. It is an exclusive system for Apple's PC and developed by Apple itself. Today, the operating system of the Macintosh has reached OS 10.15, and many features and services of the system reflect the philosophy of Apple's simple company.
Advantages: beautiful interface, easy operation, and no additional purchase is required;
Disadvantages: usually only run on Apple computers, because of the high price of Apple computers, there are relatively few Mac users.
Summary: The Mac system is an operating system deeply redeveloped by Apple based on the UNIX operating system. It is completely closed source and can only run on Apple's computers.
