Purpose: To rearrange your data in a specific sequence (like A to Z or High to Low) without removing anything.
Alphabetical (A to Z or Z to A): Great for names, cities, or product types.
lNumerical (Smallest to Largest): Best for prices, ages, or quantities.
Date (Oldest to Newest): Perfect for tracking timelines or schedules.Example -Imagine you have a list of students and their test scores.

1) SRS and Requirements Engineering (10 Marks)
Definition: Requirements Engineering (RE) is the process of eliciting, analyzing, specifying, validating, and managing requirements. SRS is the formal document stating what the system shall do (FR) and constraints/quality expectations (NFR).

1. Structural Functionalism
(Macro-level theory)
Key Thinkers: Émile Durkheim, Talcott Parsons, Herbert Spencer
Example:
Family socializes children, education prepares workforce, religion creates moral unity
2. Conflict Theory
(Macro-level theory)
Answer:
A research problem is a clear, specific, and well-defined issue or question that a researcher intends to study systematically. It represents a gap between the existing state of knowledge and the desired state, which requires investigation. A well-formulated research problem provides direction to the entire research process and helps in deciding objectives, methodology, and data collection techniques.
The sources of a research problem
Brain tumors – increased intracranial pressure (ICP).The skull is a rigid compartment; any added volume (tumor, blood, edema, CSF) raises ICP. ICP > 20 mmHg (normal < 15). CPP = MAP − ICP → rising ICP reduces CPP and causes cerebral ischemia.Causes: intracranial mass (tumor, hematoma, large infarct), cerebral edema, hydrocephalus/CSF obstruction, venous sinus thrombosis, infection, trauma, toxic or idiopathic intracranial hypertension.Pathogenesis: early compensation by displacement
1. Sociology and Social Groups
Sociology is the scientific study of human social behavior, examining how people interact in groups ranging from small personal units to large institutions.
Primary Social Groups
Small, intimate, face-to-face groups (micro level)
Primary agents of socialization
Fulfil emotional needs and shape identity
Examples: family, close friends, married couples
Members are allowed into intimate space (0–50 cm)
Secondary Social Groups
Large, formal, impersonal groups (macro

Phylum Echinodermata (from Greek echinos = spiny; derma = skin) consists of exclusively marine animals known for their pentamerous radial symmetry and unique water-driven skeletal systems.
1. General Characters
* Habitat: Entirely marine; found at all depths from the intertidal zone to the deep sea.
* Symmetry: Adults exhibit pentamerous radial symmetry (body parts arranged in fives), while larvae are bilaterally symmetrical.
* Body Organization: Triploblastic, coelomate, and exhibit an organ-
Phylum Arthropoda is the largest phylum in the animal kingdom, comprising more than 80% of all known species. Their hallmark is the presence of jointed appendages and a chitinous exoskeleton.
1. General Characters of Phylum Arthropoda
* Level of Organization: Organ-system level.
* Symmetry and Germ Layers: Bilaterally symmetrical, triploblastic, and metamerically segmented.
* Exoskeleton: A hard outer covering made of chitin, which provides protection and is periodically shed through a process
