Kiara is working on a project where she needs to understand the concept of packet switching and its application in real-life scenarios. She is also building a website where she wants to request and display various components of her web page using URLs. Alongside, she wants to understand the difference between simplex and duplex communication. Which protocol should she use to achieve all these objectives?

James, Arjun, and Leo are working on a project to build a website for their new office. They are considering whether to use HTTP, HTTPS or FTP for their URL structure. In this scenario, what would be the role of their web server?

They are discussing the characteristics of URL routing, the concepts of static, dynamic and nested routing, and the role of packet switching in data transmission. Imagine they are setting up a routing system for a remote island's local intranet that heavily relies on packet switching. What do you think they would agree on as the key components for their system?

• Packet identification, error control bits & coded data

• Fibre optic, wired and wireless

• Static, dynamic and nested routing

• Parallel and serial transmission of data

What are the benefits of using social networking websites for communication?

Charlie, Elsie, and Isabella are working on a project that involves storing sensitive data on a website. They are using URLs to access this data. What are the security measures they should take to protect this data?

• Implementing different procedures for backing up data from URL communication

• Adopting measures to protect the security of data in URL communication

Kiara is using her computer to access a website via a URL and communicate with her friend via a chat application. Considering the concepts of URLs, simplex, duplex communication and packet switching, what role does her internet browser play in this process?

• It sends messages through the internet from Kiara to other users, manages URLs, duplex communication and packet switching

• It creates web pages for Kiara, manages URLs, simplex communication and packet switching

What is the relationship between bandwidth and transmission rates?

Aarav is working on a project about packet switching in computer networks. He is interested in creating a personal blog to share his findings. Noah suggested him to learn a specific language and also mentioned about simplex and duplex communication modes. Aarav is now curious about how URLs work in this context. If Aarav wants to create web pages which can send and receive data simultaneously, and also wants to understand how URLs are used in this process, which communication mode should he focus on? And what is the main feature of the language, HyperText Markup Language (HTML), that Noah suggested?
