Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Data can be classified into structured, semi-structured, and unstructured formats:
- Structured data conforms to a rigid, predefined tabular data model (rows and columns with strict data types).
- Unstructured data lacks a predefined data model or organizational structure, making it difficult to store in conventional relational tables.
Step 1: Evaluating Each Given Activity:
(A) Writing tweets:
Tweets consist of natural language text, hashtags, emojis, and varied sentence lengths. This is qualitative text and constitutes unstructured data.
(B) Recording a video:
A video file consists of multimedia streams (pixels, frames, audio frequencies) that have no predefined relational row-and-column layout. Hence, it is unstructured data.
(C) Marking attendance by the teacher:
Attendance typically uses a predefined tabular sheet where rows represent students and columns represent dates with fixed values (Present/Absent). This represents structured data.
(D) Filling a form for opening an account:
An account form possesses designated fields (Name, DOB, Account Type) mapped directly to structured database records.
Step 2: Synthesis:
Only (A) and (B) represent unstructured data.
Final Answer:
The correct option is (A), which includes (A) and (B) only.
