competency 1.2 For AL ICT
Investigates the need of technology to create, disseminate and manage data and information.
what is computer Data processing
} Data
processing is the manipulation of data to transform it into some desired
result.
}In
the early days, it meant feeding punch cards into tabulating machines.
Computer Data processing
Computer Data processing
}Computer data processing is
any process that uses a computer program to enter
data and summarize, analyze or otherwise convert data into
usable information.
}The process may be automated and run on
a computer. It involves recording, analyzing, sorting, summarizing,
calculating, disseminating and storing data.
Because
data is most useful when well-presented and actually informative,
data-processing systems are often referred to as information systems.
Manual data processing methods
}Manual
data processing is done with pen and paper with traditional data processing
method's
} its
tough and complicating as it consumes more pages and filling it makes the data
processing work more tedious and tiresome !
}Discuss
about slowness /inaccuracy /unreliability
}Examples
for manual data processing
Electronic Data Processing (EDP)
}It is
the modern technique to process data. The data is processed through computer.
Data and set of instructions are given to the computer as input and the
computer automatically processes the data according to the given set of
instructions.
}The
computer is also known as electronic data processing machine. This method of
processing data is very fast and accurate. Now-a-days, the data is processed
and analyzed through computers. For example, the results of students are
prepared through computer; in banks accounts of customers are processed through
computers etc.
}A
Definition:
Electronic Data Processing (EDP) refers
to the use of automated measures using simple, repetitive actions -
and computer technology - to organise
and store documents and sometimes to transfer them from paper to a digital
format.
