Understanding Social Networks: A Comprehensive Overview
1. Definition of Social Networks
Social networks are forms of social interaction, defined as a dynamic exchange between individuals, groups, and institutions in complex contexts.
2. Social Networking Features
Social networks are open and continuously evolving, involving groups with shared needs and problems, organized to leverage their resources. Their purposes are varied but non-profit, ranging from connecting with classmates, friends, and relatives to fostering professional relationships and business

Understanding Mathematical Functions and Their Properties
Functions
A function, as defined by Laplace, is a law that associates each value of the independent variable x with a value of the dependent variable y. This correspondence can be written as:
A function is said to be injective if each element of the domain (set A, represented by x) maps to a unique element of the codomain (set B, represented by y). This is also known as a one-to-one correspondence.
A function is surjective if every element of the codomain (B) is an image of an element in the domain

Costing Methods in Business
Types of Costs
We analyze various types of costs, including variable and fixed costs, and how they are incorporated into different costing systems. The primary systems we’ll explore are:
- Full Costing
- Direct Costing
- Rational Imputation
Full Costing
Definition
Full costing, also known as absorption costing, incorporates all costs related to production into the cost of the products. The total cost of production for a given period is calculated as follows:
- Consumption of Raw Materials
