Classify data types (structured, unstructured, semi-structured) and understand the lifecycle of data management.
Defining data vs information and introducing the three types.
A computer system processes raw, unorganised facts called data to produce meaningful results known as information. Because data comes from various sources, it is classified into three main types based on how it is formatted.
Visual examples of structured, semi-structured, and unstructured data.

Data can be strictly structured (tables), semi-structured (tagged code), or completely unstructured (multimedia).

Capturing, Storing, Retrieving, and Deleting data.
To process data effectively, a computer system follows a sequence of steps ranging from initial input to long-term management. This is known as the data lifecycle.
Fill-blanks testing the concept of deletion and recovery.
One of the biggest threats associated with digital data is its accidental or intentional . Deleting digitally stored data means changing the details of data at the level, which can be very time-consuming. Therefore, when any data is simply deleted, its address entry is marked as , and that much space is shown as empty to the user without actually erasing it. In case data gets deleted accidentally or corrupted, there arises a need for data . This retrieval process is possible only if the memory space marked as deleted has not been by new data. If an old storage device falls into the wrong hands without being properly shredded, mischief-mongers can easily retrieve the data, posing a threat to data .
