A system is a collection of elements or components that are organized for a common purpose. The word sometimes describes the organization or plan itself (and is similar in meaning to method, as in "I have my own little system") and sometimes describes the parts in the system (as in "computer system").
the characteristics of system are
Resources
Every system requires certain resources for the system to exist. Resources can be hardware, software or liveware. Hardware resources may include the computer, its peripherals, stationery etc. Software resources would include the programs running on these computers and the liveware would include the human beings required to operate the system and make it functional.
Procedures
Every system functions under a set of rules that govern the system to accomplish the defined goal of the system. This set of rules defines the procedures for the system to Chapter 1 - Introduction to Systems operate. For instance, the Banking systems have their predefined rules for providing interest at different rates for different types of accounts.
Data/Information
Every system has some predefined goal. For achieving the goal the system requires certain inputs, which are converted into the required output. The main objective of the System is to produce some useful output. Output is the outcome of processing. Output can be of any nature e.g. goods, services or information.
Intermediate Data
Various processes process system's Inputs. Before it is transformed into Output, it goes through many intermediary transformations. Therefore, it is very important to identify the Intermediate Data. For example, in a college when students register for a new semester, the initial form submitted by student goes through many departments. Each department adds their validity checks on it.
Processes
The systems have some processes that make use of the resources to achieve the set goal under the defined procedures. These processes are the operational element of the system.
