A storage device is a hardware device capable of holding information, they are the data storage devices that are used in the computers to store the data.
Storage Devices.
There are two types of storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard drive
Without a storage device, you would not be able to save any settings or information and would be considered a dumb terminal.

Application system
Application software is all the computer system so that causes a computer to perform useful tasks (compare with computer viruses) beyond the running of the computer itself. A specific instance of such software is called a software application, application or app.
The term is used to contrast such software with system software, which manages and integrates a computer's capabilities but does not directly perform tasks that benefit the user. The system software serves the application, which in turn serves the user.
Examples include enterprise software, accounting software, office suites, graphics ,software and media players. Many application programs deal principally with documents. Applications may be bundled with the computer and its system software or published separately, and can be coded as university projects.
Application software applies the power of a particular computing platform or system software to a particular purpose.

Operating system
AnsystemAn operating system
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.
Examples of popular modern operating systems include Android, BSD, iOS, Linux, Mac OS
X, QNX, Microsoft Windows, Windows Phone, and IBM z/OS. All these, except Windows and z/OS, share roots in UNIX.
Real-time
A real-time operating system is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main objective of real-time operating systems is their quick and predictable response to events
A multi-user operating system allows multiple users to access a computer system at the same time. Time-sharing systems and Internet servers can be classified as multi-user systems as they enable multiple-user access to a computer through the sharing of time.

A computer is an electronic device that operates information, or data. It can store, recover, and processdata, according to instructions given to it in a program. You can use a computer to type documents, send email, and look through the internet.

Input Devices
What is an Input Device?An Input Device is any hardware that can insert data to a computer.Without any Input Devices a computer cannot be commanded. There are dozens of possible Input Devices but the two which are most used are, keyboard and mouse. Every time you press a key or click on the mouse you are ordering the computer to accomplish a specific action. These commands allow you to open files or programs, send messages, drag objects and perform many other functions on your computer.

SOFTWARE Computer software, describes the computer programs. Related terms such as software programs, applications, scripts, and instruction sets all fall under the category of computer software. Therefore, installing new programs or applications on your computer it would be the same that installing new software on your computer.Software can be difficult to describe because it is "virtual," or not physical like computer hardware. Software consists on lines of code written by computer programmers that have been compiled into a computer program. Software programs are stored as binary data that is copied to a computer's hard drive, when it is installed.Since software is virtual and does not take up any physical space, it is much easier (and often cheaper) to upgrade than computer hardware.While at its most basic level, software consists of binary data, CD-ROMs, DVDs, and other types of media that are used to distribute software can also be called software. Therefore, when you buy a software program, it often comes on a disc, which is a physical means of storing the software.

In information technology, an application is a computer program designed to help people perform an activity. An application thus differs from an operating system (which runs a computer), a utility (which performs maintenance or general-purpose chores), and a programming tools (with which computer programs are created). Depending on the activity for which it was designed.

Operating system
An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently make a system call to an OS function or be interrupted by it. Operating systems can be found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.
