OS frequently undergo through the upgrading system in order to make them more user-friendly. For example, Windows OS was later tailored to GUI and features such as Excel incorporated to meet the needs of the user. Another factor that leads to improvement of OS is innovativeness. Improved technology has resulted in the development of systems that can support the internet programs. Security influences the decision of upgrading OS. Due to the rising concern for viruses, there is a need for consumers to use an OS that protects them from the risks.

Three Main Components of OS

The OS has various components that make it user-friendly. The user interface is a major OS component that enables the software and hardware to communicate. To illustrate this, it helps in allocation of CPU space for running programs. The interface also supports the computer applications that enable the user to interact with the hardware. The networking element is popular in most of the current OS. It allows computers to share resources such as printers, scanners, files, and wireless connections. While the OS facilitates the networking between the resources, utility software manages the connection. Some systems have a level of security, for instance Windows 8 has an antivirus called Defender. As a result, the computer can detect virus from shared resources. The function is related to that of antivirus software that protects the computer from harmful programs.

The compatibility of the system to computers due to its low system requirements reduces the chances of computer crashes. This is unlike with Windows Vista Version, which lacked not only effective security measures, but also had high system requirements. For this reason, it was selective. Installation in computers that did not meet the requirements experienced low performance and system failure.

Operating systems are important since they facilitate the communication between software and hardware of the computer.
