These 7 open source technologies support the entire Internet age

Open source software is now a supporting technology throughout the internet age, and you may not be able to leave the web world built up of Open-source software. Now let's take a look at some of the most important open source technologies. Operating system for the Internet Linuxlinux is a free operating system, born in 1991, users can access the Internet or other channels for free, and can modify their source code. It can run major UNIX tool software, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centered design idea of Unix and is a stable multi-user network operating system. This system is designed and implemented by tens of thousands of programmers all over the world. The aim is to establish UNIX-compatible products that are freely available to the world without the copyright of any commercial software. Linux can be said to be ubiquitous, like the Android phone is based on Linux, most of the world's supercomputers are also used by the Linux system, most of the data centers using Linux as its supporting operating system. Google, Baidu, Taobao and other through the LINUXT provides us with the Internet services every day. Linux also plays an important role in aviation control systems. Encryption Internet Security protocol Opensslopenssl is a set of open source software library package, the implementation of SSL and TLS protocol. OpenSSL can be said to be a password-based security development package that encompasses the main cryptographic algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides rich applications for testing or other purposes. It can also be said that OpenSSL is a security protocol that provides security and data integrity for network communications, and SSL provides a secret transmission over the Internet, enabling communication between user/server applications not to be tapped by attackers. OpenSSL is widely used by net bank, online payment, Electronic Business website, portal website, email and other important websites. Last year OpenSSL a security breach because it was so widely used that it shook the entire Internet. The memory of the Internet--mysqlmysql is an open source small database management system, the original developer of the MySQL AB Company in Sweden, the company was acquired by Sun in 2008. Oracle acquired Sun and MySQL became Oracle's products in 2009. A lot of information is in the database, many engineers in the development of some small projects will use this MySQL database. MySQL provides API interfaces for multiple programming languages such as C, C + +, JAVA, and PHP. and support Windows, MAC, Linux and many other systems. This broad support makes it more popular with developers, and MySQL is one of the databases that developers need to master. MySQL was originally a smallApplications, but now MySQL is not a small database anymore. Basically all internet companies use the database system, and some financial transactions use MySQL as the database engine. MySQL through the corresponding tuning can not only support large-scale access, but also to ensure data security, has become a threat to the traditional business database system is an important force.
