Operating system virtualization is a method of altering a standard operating system so it may handle multiple users all at the same time. These individual users would not have any interaction with one another. Their information would also remain separate‚ even though they are using the same system. While this technology has several uses‚ the most common uses are in hosting situations and server consoladation. With operating system virtualazation‚ a single system is set up to operate like several

Types of Operating Systems Within the broad family of operating systems‚ there are generally four types‚ categorized based on the types of computers they control and the sort of applications they support. The categories are: * Real-time operating system (RTOS) - Real-time operating systems are used to control machinery‚ scientific instruments and industrial systems. An RTOS typically has very little user-interface capability‚ and no end-user utilities‚ since the system will be a "sealed box"

Components of an Operating System In order to perform the actions requested by the computer’s users‚ an operating system must be able to communicate with those users. The portion of an operating system that handles this communication is often called the user interface. Older user interfaces‚ called shells‚ communicated with users through textual messages using a keyboard and monitor screen. More modern systems perform this task by means of a graphical user interface (GUI) in which objects to be

Solar energy is a vital untapped resource in a tropical country like ours. The main hindrance for the penetration and reach of solar PV systems is their low efficiency and high capital cost. “Solar Panel Maximum Power Point Tracker”. As the name implied‚ it is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply and since every
