What is Data?

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.

The Data Spectrum

Visual examples of structured, semi-structured, and unstructured data.

A rich vibrant illustration, Kurzgesagt-inspired, bold shapes with subtle texturing, saturated but harmonious color palette, strong composition, professional science museum display quality. Three distinct visual buckets or containers representing data types. Bucket 1 holds a perfectly neat Excel spreadsheet grid. Bucket 2 holds glowing lines of code with visible HTML tags. Bucket 3 overflows with a chaotic mix of a photograph, a video play button, and musical notes.

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

Test: Data Deletion

Fill-blanks testing the concept of deletion and recovery.

0 of 6 blanks filled
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 thelevel, 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 beenby 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.
