Introduction to Computer Information Systems/Print version
Von-Neumann computer consists of two main components: memory and CPU. This concept has not yet been overcome and even the latest computers still come from von-Neumann architecture.
An application software is a computer program designed to perform a group of coordinated functions, tasks, or activities. Applications may be connected with the computer and its system software or may be published separately, and may be coded as proprietary or open-source. Operating system is defined as a system software that manages computer hardware and software resources and provides common services for computer programs.
All cpplication softwareomputer programs require an operating system to function. Operating system controls computer's hardware, run the computer's programs and organizes files. Any hardware that can hold information, temporarily or permanently. We distinguish two types of storage: a primary storage device RAM , and a secondary storage device hard drive. Secondary storage can be removable, internal, or external storage. It stands for random access memory, it keeps the data and general purpose program that the compter is executing at the moment.
RAM is not permanent, its contain can be changed and it is erased when the computer is off. It is the physical arrangement in a computer that contains the computer's basic circuitry and components. Bit is the smallest storage unit in the computer. A bit can store just 0 or 1, which is called binary, and therefore can be stored by physical devices or systems that has two separate states.
Notice that a bit has only two coding options, or 2 values. One bit is too small to be used, and thus computers use a larger storage unit called bytes. Bytes - are made of bits. Notice that a Byte has 2 8 coding options, values. RAM, hard drives and flash drives, are all types of storages measured by Bytes.
It can be any character, including text and numbers, pictures, sound, or video. If data is not put into context, it doesn't do anything to a human or computer. Within a computer's storage, data is a collection of numbers represented as bytes that are in turn composed of bits. For instance letter A, is only a data for an illiterate person but an information for someone who can read. Knowledge can refer to a theoretical or practical understanding of a subject. A computer program can be viewed as an elaborate algorithm.
In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.

Operating system is defined as a system software that manages computer hardware and software resources and provides common services for computer programs.
Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system hardware. This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software. Practical computer systems divide software into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred. Computer software has to be "loaded" into the computer's storage such as a hard drive, memory, or RAM. This involves passing instructions from the application software, through the system software, to the hardware which ultimately receives the instruction as machine code. Each instruction causes the computer to carry out an operation -- moving data, carrying out a computation, or altering the control flow of instructions. Reference Terms.

Today's world runs on computers. Nearly every aspect of modern life involves computers in some form or fashion. As technology is advancing, the scale of computer use is increasing. Computer users include both corporate companies and individuals.
Computer hardware is any physical device used in or with your machine, whereas software is a collection of programming code installed on your computer's hard drive. In other words, hardware is something you can hold in your hand, whereas software cannot be held in your hand.
