The former is a closed system developed by Apple and is only used by Apple devices. Linux is an open source free system that can run on many kinds of devices and also allows developers to use it for secondary purposes. Development
macOS is a graphical interface operating system, similar to Windows. Linux is a pure code operation without seeing the interface, which is confusing for novices (recommended learning:linux tutorial)
macOS is suitable for office and entertainment use by ordinary users, and Linux is suitable for use as a server. Because there is no graphical interface and it takes up very little memory, many webmasters have chosen the Linux series of operating systems
Mac OS The difference is that one is UNIX, the other is Linux
One is developed by the richest IT company in the world, and the other is developed by I don’t know how many companies and how many versionsMac OS is an operating system that runs on Apple's Macintosh series of computers.
Mac OS is the first graphical user interface operating system to be successful in the commercial field. The latest current system version is macOS 10.15 beta 4, and there is also a Mac system (Hackintosh) running on PC on the Internet.The Mac system is a graphical operating system based on the Unix kernel; an operating system that generally cannot be installed on an ordinary PC.
Developed by Apple itself. The Apple operating system has reached OS 10, codenamed Mac OS X (X is the Roman numeral for 10). This is the biggest change in the 15 years since the birth of MAC computers. The new system is very reliable; many of its features and services reflect Apple's philosophy.In addition, the raging computer viruses are almost all targeting Windows. Since the architecture of MAC is different from that of Windows, it is rarely attacked by viruses. The macOS operating system interface is very unique, highlighting vivid icons and human-computer dialogue. Apple not only develops its own systems, but also involves hardware development.
Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and Unix.
It can run major Unix tool software, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.With the development of the Internet, Linux has received support from software enthusiasts, organizations, and companies around the world.
In addition to maintaining a strong momentum of development in server operating systems, it has also made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve the operating system according to their own needs to maximize it to meet the needs of users.The above is the detailed content of The difference between mac and linux.

linux设备节点是应用程序和设备驱动程序沟通的一个桥梁;设备节点被创建在“/dev”,是连接内核与用户层的枢纽,相当于硬盘的inode一样的东西,记录了硬件设备的位置和信息。设备节点使用户可以与内核进行硬件的沟通,读写设备以及其他的操作。

区别:1、open是UNIX系统调用函数,而fopen是ANSIC标准中的C语言库函数;2、open的移植性没fopen好;3、fopen只能操纵普通正规文件,而open可以操作普通文件、网络套接字等;4、open无缓冲,fopen有缓冲。

端口映射又称端口转发,是指将外部主机的IP地址的端口映射到Intranet中的一台计算机,当用户访问外网IP的这个端口时,服务器自动将请求映射到对应局域网内部的机器上;可以通过使用动态或固定的公共网络IP路由ADSL宽带路由器来实现。

在linux中,交叉编译是指在一个平台上生成另一个平台上的可执行代码,即编译源代码的平台和执行源代码编译后程序的平台是两个不同的平台。使用交叉编译的原因:1、目标系统没有能力在其上进行本地编译;2、有能力进行源代码编译的平台与目标平台不同。

在linux中,eof是自定义终止符,是“END Of File”的缩写;因为是自定义的终止符,所以eof就不是固定的,可以随意的设置别名,linux中按“ctrl+d”就代表eof,eof一般会配合cat命令用于多行文本输出,指文件末尾。

linux查询mac地址的方法:1、打开系统,在桌面中点击鼠标右键,选择“打开终端”;2、在终端中,执行“ifconfig”命令,查看输出结果,在输出信息第四行中紧跟“ether”单词后的字符串就是mac地址。

在linux中,可以利用“rpm -qa pcre”命令判断pcre是否安装;rpm命令专门用于管理各项套件,使用该命令后,若结果中出现pcre的版本信息,则表示pcre已经安装,若没有出现版本信息,则表示没有安装pcre。

在linux中,rpc是远程过程调用的意思,是Reomote Procedure Call的缩写,特指一种隐藏了过程调用时实际通信细节的IPC方法;linux中通过RPC可以充分利用非共享内存的多处理器环境,提高系统资源的利用率。
