The Secure Sockets Layer (SSL) protocol ensures secure data transfer by encrypting information. The process begins with an SSL handshake, where the client and server establish a secure connection. The server sends its public key to the client, which verifies the authenticity by checking the digital certificate.

Once verified, the client creates a session key and encrypts it with the server's public key. This session key is only shared between the client and server, ensuring privacy in communication. All data transferred once the session key is established is encrypted using this key, maintaining confidentiality.

A switch connects devices in a network to a central location, enabling them to communicate with each other efficiently. It receives data packets from one device and forwards them to the appropriate destination device.

A router connects different networks together, directing data packets between them. It manages traffic and determines the best path for data to travel from the source to the destination.

A modem modulates and demodulates signals for internet connectivity, allowing digital data from a computer to be transmitted over telephone lines or other communication mediums.

A firewall acts as a barrier between the computer and the internet, monitoring and controlling incoming and outgoing network traffic. It checks programs attempting to access the internet and blocks any unauthorized access, thus preventing malicious attacks from reaching the computer.

A peer-to-peer network may be more suitable as it allows direct communication between devices (client to client), which can reduce the load on a central server and speed up the transfer process by distributing the data across multiple connections.

Files are transferred using the FTP protocol by establishing a connection between a client and a server. The client sends a request to the server to access and retrieve specific files. This protocol facilitates the secure and efficient transfer of files over the network.

Shaping refers to the practice of controlling the data flow on a network to optimize bandwidth usage and ensure essential services receive prioritized access, thus preventing congestion during peak times.

Throttling, on the other hand, is the intentional reduction of bandwidth for certain applications or users to prevent excessive consumption, ensuring a fair distribution of available bandwidth among all users.

The Internet of Things (IoT) refers to the interconnected network of physical devices embedded with sensors and software that enables them to collect and exchange data over the internet, enhancing automation and efficiency.

1. Smart lighting systems that adjust based on game activities for an immersive experience.
2. Wearable devices that track player performance and provide real-time feedback to enhance gameplay.
