The modern world has numerous kinds of systems that influence daily life. Some examples include transport systems; solar systems; telephone systems; the Dewey Decimal System; weapons systems; ecological systems; space systems; etc.

Noun. 1. modern world – the circumstances and ideas of the present age; “in modern times like these” contemporary world, modern times, present times. times – a more or less definite period of time now or previously present; “it was a sign of the times”

A world-system is a social system, one that has boundaries, structures, member groups, rules of legitimation, and coherence. Its life is made up of the conflicting forces which hold it together by tension and tear it apart as each group seeks eternally to remold it to its advantage.

These different body systems include the skeletal, nervous, muscular, respiratory, endocrine, immune, cardiovascular/circulatory, urinary, integumentary, reproductive, and digestive systems.

Characteristics of a system:

• Organization: It implies structure and order.
• Interaction: It refers to the manner in which each component functions with other components of the system.
• Interdependence: It means that parts of the organization or computer system depend on one another.
• Integration: It refers to the holism of systems.
• Central Objective:

A system has three basic elements input, processing and output. The other elements include control, feedback, boundaries, environment and interfaces. Input: Input is what data the system receives to produce a certain output. Output: What goes out from the system after being processed is known as Output.

The Components of Information Systems. Information systems can be viewed as having five major components: hardware, software, data, people, and processes. The first three are technology.

A computer system mainly has three components viz. Input Unit, Central Processing Unit and Output Unit. These components are the building blocks of a computer and define its architecture.

Computer Block Diagram System: Mainly computer system consists of three parts, that are central processing unit (CPU), Input Devices, and Output Devices. A large amount of data is stored in the computer memory with the help of primary and secondary storage devices. The CPU is like the heart/brain of the computer.

There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power. It is used mainly to start or boot up a computer.
