Cybersecurity Techniques: Email Tracking, Keylogging, and HTTP Tunneling
Email Tracking Explained
Definition
E-mail tracking is the technique used to monitor and record information about emails sent, such as whether the email was opened, when it was opened, how many times it was opened, and from which location or IP address. It is mainly used during footprinting and information gathering to collect useful details about the recipient.
Explanation
E-mail tracking works by embedding a tracking element (such as a tracking pixel or link) inside the email. When the receiver opens

Unary, Binary, and Ternary Operators in C
A unary operator in C is an operator that works on only one operand. Common unary operators include ++ (increment), -- (decrement), - (unary minus), ! (logical NOT), and sizeof.
A binary operator in C is an operator that works on two operands. Examples include:
- Arithmetic operators:
+,-,*,/,% - Relational operators:
==,!=,>,<,>=,<= - Logical operators:
&&,|| - Bitwise operators:
&,|,>>,<< - Assignment operators:
=,+=,-
Database Systems: Architecture, Design, and Normalization
Three-Level Database Architecture
The three-level (three-schema) architecture separates how data is physically stored, logically structured, and viewed by different users. This is the ANSI/SPARC architecture, and it exists mainly to provide data abstraction and data independence.
External, Conceptual, and Internal Levels
- External (View) level: This is the level closest to the users; it defines multiple user views (external schemas). Each view shows only part of the database relevant to that user or
