Hey everyone
I am taking ICT 9626 as an a-level subject and I do not have enough resources, please can anyone help me by sharing theirs.
It would mean a lot to me, thanks.

To be precise, I do not have notes on a sub-topic - encoding.

Encoding is transforming the data from one format into another. It can include shortening, symbol replacement or abbreivations.
Encoding is not the same as cryptography
The aim of encoding is not to increase security.

pros/advantages:
-Less memory requirement: storing less information, tehrefore lessmemory is required (since encoding is about shortening the data/information)
-security: if the codes are not apparant then itis difficultto know and udnerstand the meaning of the codes.
-speedof input: the codes take less time to enter, therefor it is quicker to input a large volume of data
-data validation:since the codes follow a strict set of numbers and letters they are easy to validate.
organisations of data: if the data is in a standardised format then it can be comapred and organised.

cons/disadvantages:
-the precision of data is coarsened
-encoding of value judgements
-the user needs to know the codes used: the codes cannot be sued if the user does not know them.
-there are a limited number of codes
-it is difficult to track errors
