Characteristics & functions of a System : By Mariyam Liusha Characteristics & functions of a System What is a SYSTEM? : What is a SYSTEM? System is a set of interacting or interdependent entities forming an integrated whole.
A system is a collection of parts that interact with each other to function as a whole. Characteristic of a System : Characteristic of a System Objective
Every system has a predefined goal or objective towards which it works.
For example: an organization would have an objective of earning maximum possible revenues, for which each department and each individual has to work in coordination. Slide 4: Standards
It is the acceptable level of performance for any system.
For example take a sorting problem. There are various sorting algorithms. But each has its own complexity. So there should be a standard or rule to use a particular algorithm. Slide 5: Environment
Every system whether it is natural or manmade co-exists with an environment. It is very important for a system to adapt itself to its environment.
For example, humans live in a particular environment. As we move to other places, there are changes in the surroundings but our body gradually adapts to the new environment. Slide 6: Feed Back
Feedback is an important element of systems.
The output of a system needs to be observed and feedback from the output taken. Slide 7: Boundaries
Every system has defined boundaries within which it operates. Beyond these limits the system has to interact with the other systems.
Example: Personnel system in an organization has its work domain with defined procedures. If the financial details of an employee are required, the system has to interact with the Accounting system to get the required details. Slide 8: Interface
Interfaces are another important element through which the system interacts with the outside world.
System interacts with other systems through its interfaces. Users of the systems also interact with it through interfaces. Most systems share common characteristics : Most systems share common characteristics Systems have structure, defined by parts and their composition
Systems have behavior, which involves inputs, processing and outputs of material, energy or information.
Systems have interconnectivity: the various parts of a system have functional as well as structural relationships between each other. Some functions of a system : Some functions of a system Modular Design, Expandability, Flexibility
Modular hardware and software design provides the ability to adapt and expand the system to cater for virtually any configuration or application required - small or large.
Configuration options within the programming allow Security, Access Control and Building Automation to exist as separate entities within the same system or to be integrated to whatever extent required.
Overall system dimensions can be expanded beyond the capacity of a single control panel using powerful system management software. Slide 11: Integration
The various Concept Module components can be installed to offer independent Intruder Alarm or Access Control or Building Automation functionality or these functions can be integrated to whatever degree is desired.
All common 'integrated' functionality is embedded in the system programming simply requiring Installers to select an option. Slide 12: Thank You
