Data Exchange – Packet Switching
Packet switching is a method used in networking to divide data into small packets, which are sent over various routes and reassembled at their destination. This process enables efficient and flexible internet communication by breaking large data into manageable pieces. Each packet contains part of the data, along with addressing information to ensure it reaches the correct destination. Routers play a key role in packet switching by directing these packets along the most efficient path, ensuring reliable delivery even if some routes are unavailable. This system allows networks to handle multiple communications simultaneously and maintain robust connectivity.

Data Exchange – Transmission
Data transmission refers to the process of sending data from one device to another. There are several methods of transmission: serial transmission sends data one bit at a time over a single channel, parallel transmission sends multiple bits at once over multiple channels, and wireless transmission uses radio waves to send data without physical connections. Over the internet, data is transmitted through a combination of cables, routers, and wireless signals. Reliable transmission is crucial to ensure data integrity, as it prevents errors and ensures that data reaches its destination accurately and intact, maintaining the quality and reliability of communication.

Client-side Processing
Client-side processing plays a critical role in web development by executing scripts directly in the user's browser. This approach enables faster interactions, reducing the need to communicate with a server for every action. Technologies like JavaScript and HTML5 enhance user experience by enabling dynamic content updates, animations, and form validations without reloading the page. Benefits include reduced server load and improved responsiveness, while limitations involve security concerns, as code runs locally, and dependency on the user's device capabilities. Understanding client-side processing is essential for creating interactive, user-friendly websites.
Client-side processing
Server-side Processing
Server-side processing involves operations performed on a web server, rather than the user's device. This processing handles tasks that require secure data storage, complex calculations, or communication with databases.Role: Server-side processing enables dynamic content generation, user authentication, and data management.
Technologies: Common server-side technologies include PHP, ASP.NET, and Node.js, each offering unique features for handling requests and generating responses.
Functionality & Security: Server-side processing ensures security by keeping sensitive data hidden from the client, while enabling database access and complex operations, which cannot be handled on the client side.

Database Theory
Database theory focuses on the fundamental principles of organizing, storing, and retrieving data efficiently. Key concepts include the design and structure of databases, with tables, fields, and relationships in relational databases, or flexible storage in NoSQL systems. Relational databases store data in structured tables, while NoSQL databases use unstructured formats for scalability and flexibility. Cloud databases store data online, enabling remote access and dynamic scaling. Data is retrieved using queries, typically SQL in relational databases, or other specialized query languages in NoSQL databases. A well-designed database ensures data integrity, security, and fast access.

Threats to Data
Data faces numerous security threats, including malware, hacking, and phishing attacks. Malware can infiltrate systems to corrupt or steal data, while hackers exploit vulnerabilities to gain unauthorised access. Phishing deceives individuals into revealing sensitive information through fake communications. Data can be compromised through weak passwords, unencrypted storage, or unauthorised physical access. These breaches can lead to financial losses, reputational damage, and regulatory penalties. Effective data protection strategies, such as strong authentication, encryption, regular software updates, and employee training, are essential. Risk mitigation plans, including backups and incident response protocols, safeguard organisations against data theft and ensure business continuity.
