Encoding Data

Encoded Data

Encoded data is data that has been changed by a algorithm so that if people get the data and they aren't meant to have it they won't be able to understand what it means and therefore it will be no use to them. If the people who were meant to recieve it and get it they will be able to uncode it and then use the data.

Reasons for Encoding Data

• coded data takes less effort to type in
• more data can appear on the screen
• takes up less storage space (less important as storage media is cheap)
• it is easier to check that a code is accurate using validation checks.
• Better security as the data will be encoded and therefore if people who shouldn't have the data get it they won't be able to uncode it or will take them a lot longer to uncode it and gain access to it
• Less typing so less…
