3.1 Networks are used at the studio to allow for fast and efficient communication to take place - NSC Information Technology - Question 3 - 2024 - Paper 2

Transferring data using SSL (Secure Sockets Layer) involves several key steps:

1. Establishing a Secure Connection: When a client connects to a secure server, the server sends its SSL certificate, which includes the server's public key.
2. Certificate Verification: The browser checks the authenticity of the SSL certificate with a trusted Certificate Authority (CA).
3. Session Key Creation: A session key is generated which is unique for each session, and the server encrypts this session key with the public key before sending it to the client.
4. Encrypted Communication: The session key is used for symmetric encryption of the data transferred, ensuring that both client and server can encrypt and decrypt messages securely.

A switch connects devices within a network to a central location, facilitating communication by directing data packets between devices on the same network.

A router connects different networks together, forwarding data packets between them, and often provides Wi-Fi connectivity.

A modem converts digital data from a computer into the analog signal required for transmission over telephone lines and vice versa, allowing internet access.

A firewall acts as a barrier between a computer and the internet by monitoring incoming and outgoing traffic. It prevents unauthorized access by blocking unwanted communication and threats, thus protecting the computer from potential attacks.

A peer-to-peer network may be more suitable because it allows direct communication between devices, reducing the load on a central server and speeding up the transfer process by distributing the data across multiple connections.

The FTP (File Transfer Protocol) is used to transfer files between a client and a server. It establishes a connection where the client sends commands to the server to request and receive files, enabling efficient file exchange over a network.

Shaping and throttling are techniques used to manage network bandwidth.

• Shaping involves prioritizing specific types of traffic to ensure essential services have enough bandwidth, improving overall network performance.
• Throttling reduces the speed of certain types of data transmission, preventing excessive use of bandwidth and ensuring fair access for all users.

The Internet of Things (IoT) refers to the interconnection of everyday devices to the internet, enabling them to send and receive data. This connectivity allows for automation, remote control, and data analysis, enhancing functionality.

1. Smart lighting systems that adjust based on player activity or game scenarios.
2. Automated inventory tracking systems that monitor and manage game development resources.
