SYSTEM:- A system is begin ordinary grouping inter depend component link according to plan to achieve a specific goal.
The component of system refer to physical path like input output devices, memory coma processor and management step (planning, organing and controlling) aur a subsystem in a multilevel structure. The component may be simple or complex or advance.
DEVICE:- A device is a unit of physical hardware or equipment that provides one or more computing functions within a computer system. ... Typical hardware includes a computer mouse, speakers, printer and microphone. A device may also be referred to as an appliance, gadget or electronic tool.
DATA:- Any thing That we entered in Computer is Called DATA.
Data is the form of digits, Text, Picture, Video, Expression, Voice, etc.
All Data is an Information but Information is Not Data..
INFORMATION:- Accurate and time-bound, specific and organized data for any purpose, which can be presented in a context and give meaning and relevance to it and increase understanding and decrease uncertainty, we can call it information.
किसी उद्देश्य के लिए सटीक और समयबद्ध, विशिष्ट और संगठित डेटा, जो किसी संदर्भ में प्रस्तुत किया जा सके और उसे अर्थ और प्रासंगिकता दे सके और समझ में वृद्धि और अनिश्चितता में कमी ला सके उसे हम इनफार्मेशन कह सकते हैं |
TECHNOLOGY:- Technology is the application of scientific knowledge for practical purposes or applications, whether in industry or in our everyday lives. So, basically, whenever we use our scientific knowledge to achieve some specific objective, we are using technology. ... Technology is not a neutral term.
