World Cup Limit Trigger
Shortly after the birth of the computer, it was discovered that certain jobs were implemented in many different programs, such as calculating some standard mathematical functions. For efficiency reasons, the standard versions of these programs are collected into a "library" for each program to call. Many tasks often have to deal with a wide variety of input and output interfaces, in which case the library used for the connection can come in handy.
In the 1960s, with the spread of computer industrialization, computers were increasingly used as a process for different jobs within an organization. Soon, special software that automatically schedules and resumes jobs appears. These software, which controls both the hardware and the job scheduling, is called the "operating system." An example of an early operating system is IBM's OS/360. In the continuous improvement, the operating system has introduced a time sharing mechanism - concurrency. This allows multiple different users to "simultaneously" use the machine to execute their own programs, which looks like everyone has a computer of their own. To do this, the operating system needs to provide a "virtual machine" like each user to separate the different programs. Since the number of devices that require operating system control is also increasing, one of them is the hard disk. As a result, the operating system introduces file management and directory management (folders), which greatly simplifies the application of such permanent storage devices. In addition, the operating system is also responsible for security controls, ensuring that users can only access files that have been allowed. Of course, the last important step in the evolution of the operating system so far is to provide a standard graphical user interface (GUI) for the program. Although there are no technical reasons why the operating system must provide these interfaces, operating system vendors always want and encourage software running on their systems to be consistent or similar in appearance and behavioral characteristics to the operating system.
