A. INFORMATION VS. DATA
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,
communication,
control,
data,
form,
instruction,
knowledge,
meaning,
mental stimulus,
pattern,
perception, and
representation. It is also the facts that was received and understood by. While
Data are pieces of information that represent the qualitative or quantitative attributes of a variable or set of variables. Data (plural of "
datum") 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. It is the fact that can be drawn.
B. DATA STORAGE VS. COMPUTER STORAGE
Actually Data Storage is just part of Computer storage because Data Storage is just part of the memory of the computer where data was saved.
Computer data storage, often called
storage or
memory, refers to
computer components, devices, and
recording media that retain digital
data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a
central processing unit (CPU, a processor), implements the basic computer model used since the 1940s. While Computer Storage is the memory that where documents are saved like for example Hard Disks.
C. OPERATING SYSTEM VS. COMPUTER SYSTEM
Operating System is a system that is tasks to manipulate computer programs.
Operating system (commonly abbreviated to either
OS or
O/S) is an interface between hardware and user; it 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
computing applications that are run 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. Almost all computers (including
handheld computers,
desktop computers,
supercomputers,
video game consoles) as well as some
robots, domestic appliances (dishwashers, washing machines), and
portable media players use an operating system of some type.
[1] Some of the oldest models may however use an
embedded operating system, that may be contained on a
compact disk or other
data storage device. While a Computer System is a complete, working
computer. The computer system includes not only the computer, but also any
software and
peripheral devices that are necessary to make the computer function. Every computer system, for example, requires an
operating system. It can also manipulate many computers like computer station.
