The operating system or OS is a basic program that manages the components of a computer such as memory, hard disk space, input and output devices and made available for applications whether server, mainframe, PC, tablet or smartphone an operating system can be found in almost every type of computer. It manages user communication and access rights, controls the loading, execution and termination of application software, manages the processor performance as well as the storage capacities and operation of connected devices such as a mouse, fact, printer, scanner, cameras, etc. With the write csv files python you can now have the best deal.
Development of the operating systems
The first computers worked without an operating system. On the one hand, the hardware was little differentiated and thus manageable, secondly, they could only work off a specific program. Rudimentary systems emerged in the late 1950s. The first operating system that could be used in several model series was OS or 360 from IBM, introduced with the Hardware System or 360 in 1964. In the early 1970s, UNIX created a system family for different hardware platforms.
With the C64 began the triumph of home computers. This device had a core kernel called Kernel and BIOS that controlled the connected components. Almost parallel, Apple’s macOS systems were developed with the first graphical user interface and DOS, which was driven primarily by Microsoft and became the leading operating system for a few years through smart corporate policies. DOS was controlled via command lines with the direct entry of commands.
However, it was clear early on that the graphical user interface was the future. Therefore, Microsoft began in 1983 with the development of Windows, which is the world leader in the PC sector to this day. It is now available in the Windows 10 version and undergoes regular updates. A version 11 should not exist according to the manufacturer. The open-source operating system Linux remains, although repeatedly praised, with only about 1% market share an exotic.
Strong changes through mobile devices
With the introduction of the first iPhone and the rapid development of mobile devices since then, the market for operating systems has also changed dramatically. Although Windows is still one of the top dogs with around 40%, it could not prevail on smartphones and is essentially limited to PCs and notebooks.
In the meantime, Android is playing the first fiddle with more than 40% market share in mobile devices, and the trend is rising. Android is open-source software that is used by more than 80 hardware manufacturers and software developers under the leadership of Google and dominates the smartphone market. Apple has also developed its own operating system for its iPhones with its iOS and comes to around 15% shares.
Do it yourself, but of course only your own systems to check the vulnerability to attacks and detect vulnerabilities. For this, there are tools e.g. Nmap or OpenVAS, which automatically scan the own system for security gaps and reveal gaps. For safety-critical systems, however, a specialist should be consulted who, for example, can carry out a penetration test.
Check log files
Using log files attacks and attempted attacks can be detected. To determine if additional security mechanisms need to be taken, log files that the operating system records should be periodically reviewed.
