Operating systems what is it, types of OS and which one to choose This term is applied not only to ordinary personal computers (PCs), but also to any other computing systems - from smartphones to supercomputers The operating system is the most important program on a PC A computer, laptop, tablet, or phone must have an operating system. This is an interface (bridge) between the hardware in the computer unit or phone case (processor, memory, hard disk) and the user. It is designed to manage the entire operation of the computer, the efficient use of its resources. The OS is a "Big Boss" that performs the following functions: manages free resources of RAM, hard drives or memory cards; The first truly popular operating system was Windows 95 and its main feature was the graphical interface that allows you to control a computer with a mouse, which made it accessible to more people. The operating systems that existed before required specific knowledge (commands) to work with a PC. The main types of operating systems imply a division into single-tasking and multitasking. Modern operating systems belong to the second type, i.e. they are able to solve several tasks simultaneously. This also includes the most popular — Microsoft Windows, Linux, macOS. Everyone has advantages and disadvantages. Let's look at each of them in more detail. Windows is the most common OS on earth Windows has a lot of advantages over competitors, here are some of them: reliable hardware support (video cards, audio cards, printers, video cameras, etc.); But there are also some disadvantages: long OS loading; Every user is able to figure it out in a couple of hours without any problems, this is the secret of popularity. Linux is reliability and security everywhere The main heart is the kernel, which has driver support installed (for working with other devices). The main concept in this OS is a package, because it consists entirely of packages. If in Windows each application occupies its own folder, then in Linux the files are in different folders: the launching programs are in one place, the configuration files associated with the program settings are in another folder. Such storage and location of files confuses users, but, from the point of view of logic, such a separation seems reasonable. Let's highlight the advantages of this OS: the system is free of charge (on the site with the selected distribution, we download the necessary image, write it to a USB flash drive and install it on users' computers); incomplete hardware support (video cards, audio cards, printers, etc.), but the situation is constantly improving, with each new release more and more devices are supported; Linux distributions are becoming more and more "friendly" to the user, offering a nice graphical interface, practical package managers, a growing set of games and applications (Ubuntu, Linux Mint distributions are suitable for beginners at the beginning of use). Mac OS is an OS created for professionals Mac OS is a closed OS based on Unix-like systems (similar to Linux), the difference is that the source code is closed, and it is a paid operating system. The advantage of a closed system is that applications are brought to perfection when working under one architecture, which increases the speed of applications, increasing effective interaction with memory and other processes. There is also a significant disadvantage — the almost complete absence of games for this operating system. Apple computers are platforms made and created not for home, but for work. Which operating system to choose The operating system is the main component of a computer and any device like it. If you need the simplicity and convenience of installing programs, configuring peripherals, then the Windows OS line will be the best choice. Go back |
