DATA

Lets recall back what we have learned before…

Do you still remember what are the 5 parts

of

information systems??

We have discuss about the people which is the users…

The procedures – the guidelines for computer operations..

Software….

Hardware……

And

 connectivity….

Now

We want to discuss on the last part of IS…

……DATA….

We conclude data as >> anything that can be stored….

Includes

Audio, music, photographs, video, etc…

There are 2 ways/ perspectives to view data

1^st

Physical view

N 2^nd

Logical view….

By physical view>>the data is viewed how it really looks like…(how the computer talk each other) using binary representation. only very specialized computer professionals are concerned with this view…

By logical view>>> data is viewed in the form of that how human understand it and interpret it..

e.g. on the screen appear your name “SYUHADA”… u may understand it.. but if the computer shows the binary representation like ‘0000011001010’

U may not understand right???? how to read it??

That is why the ‘language’ used by the computer are different by operations views and human views.

Software and hardware make it more easier where they translates the digital forms into a kind of information that human can understand ……

So, remember that data has two ways / perspectives to view….

Physical view

&

Logical view………

Make sure u don’t be confusing on both of them …OK?????
