DATA VS INFORMATION
Data are pieces of information that represent the qualitative or quantitative attributes of a variable or set of variables. Data are typically the results of measurements and can be the basis of graphs, images or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and knowledge are derived while Information as a concept has a diversity of meanings, from everyday usage to technical settings. Generally speaking, the concept of information is closely related to notions of constraint, communications, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, and representation.

COMPUTER STORAGE VS DATA STORAGE
Computer Storage memory, components, devices and media that retain digital data used for computing for some interval of time while Data Storage records or retrieves information from any medium, including the medium itself.

An operating system (commonly abbreviated to either OS or O/S) is an interface between hardware and user; an OS is responsible for the management and coordination of activities and the sharing of the resources of the computer. The operating system acts as a host for computer applications that are ran on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications while Computer system is a machine that manipulates data according to a set of instructions. Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.
