operating system using the existing hardware resources. So if you want to learn another operating system like Linux, you can use virtualization to run Linux on top of the existing operating system. Virtualization is the abstraction of IT resources, separating their physical instance and boundaries from their function. Virtualization has brought important innovation to IT Virtualization concept was first developed by IBM in the 1960s to fully utilize mainframe hardware by logically partitioning them

computing systems in different ways, always with difficulty. We will look at some of the terminology used to describe different types of computing systems, from the ubiquitous micro to the extremely powerful supercomputer. Common terms, such as hardware and software, will be discussed. Different methods of processing data and information will be explained. After this brief survey, we will come back, in later lessons, and explore in greater detail the topics introduced here. Data and information processing

are complex machines comprised of two key areas. Do you know what they are? The answer is hardware and software. Computer hardware is the physical components that you can touch and feel. Computer software is programs that run on the hardware. A lot of people may not know the difference between them. It might be best to tell the difference between them and how they work together. Computer hardware is made up of the keyboard, mouse, monitor, central processing unit (CPU), scanners and printers

about Apple’s clean software interface versus Android’s, I am also going to explain the processes involved in security updates, and software updates all together. All these combined will construct a pattern of how 90% of all Apple users stay up to date with the most current software while Android has a consistent 35% that are up to date. Apple devices are known to have a cleaner software to hardware integration because Apple specifically designs and fabricates software and hardware for each other while

into information (output). Computer carries out processes using Instructions, which are the steps that tell the computer how to perform a particular task. A collection of related instructions organized for common purposes is referred to as software. Some people refer to the series of input, process, output, and storage activities as the information processing cycle. Advantages of using Computers Speed- when data, instruction, and information flow along electronic circuits in a computer
