Tpr2_u3: The Internet 1/3

The laptop uses a wireless connection to the modem-router. This means that it is able to connect to the internet without the need for any physical cables. The modem-router sends out a wireless signal that the laptop can pick up and connect to, allowing it to access the internet.

In this scenario, the client refers to the application that the person is using to send the picture, which is WhatsApp. The person is using their mobile phone to send the picture, so the correct answer is the application they are using at the moment.

The correct answer is "a laptop and a desktop computer" because the question asks for a digital device, and both a laptop and a desktop computer are digital devices. The other options, such as a mobile phone, a smart TV, and a tablet, are also digital devices, but they are not the best choices because they do not fulfill the requirement of needing a laptop and a desktop computer.

The modem-router is connected to the telephone line with a telephone cable (RJ11)/optic fiber cable. This is because the telephone line is the primary means of connection for the modem-router, and a telephone cable (RJ11) or optic fiber cable is typically used to establish this connection. The other options, such as using an ethernet cable (RJ45) or HDMI cable, are not commonly used for connecting a modem-router to a telephone line.

A browser is a program that allows users to access and view web pages on the internet. It acts as a gateway between the user and the internet, displaying the content of websites and allowing users to navigate through different pages. Without a browser, it would not be possible to connect to the internet and complete ICT activities as mentioned in the question.

The given answer "router" is correct because a router is a device that connects multiple devices to a network. It acts as a central hub, allowing devices such as computers, smartphones, and tablets to connect to the internet or communicate with each other within a local network. By connecting all digital devices to a router, they can share resources, access the internet, and communicate with each other seamlessly.

The correct answer is a switch with ethernet cables (RJ45) because ethernet cables (RJ45) are used to connect computers to a switch, allowing them to communicate with each other within a local area network. The other options mentioned, such as a modem-router with ethernet cables (RJ45), a switch with a telephone cable (RJ11), or a modem-router wirelessly, do not provide the necessary connectivity for desktop PCs to be connected together.

The correct answer is "the application my friend is using at the moment." In this scenario, the friend is using the WhatsApp application on their mobile phone. The client refers to the software or application that is used to access a service, in this case, WhatsApp. The WiFi connection, WhatsApp server, and your mobile phone are not the clients in this context.

The ICT activities are stored in a computer called a server, which acts as a central repository for the different files or web pages. When accessing these files, my laptop acts as the client and connects to the server to retrieve the information.

An ISP, or Internet Service Provider, is a company that provides individuals and businesses with access to the internet. They offer various plans and packages to connect users to the internet through different technologies such as DSL, cable, or fiber-optic connections. Users pay a fee to the ISP for this service, which allows them to browse the web, send emails, stream videos, and perform other online activities. The ISP is responsible for maintaining the network infrastructure and ensuring a reliable and secure internet connection for its customers.

The connection between our router and the ISP can use an optical fiber cable because it provides high-speed data transmission over long distances. Additionally, a telephone cable (RJ11) can be used for the connection because it is commonly used for DSL internet connections, which utilize existing telephone lines for internet access.

In order to connect to the Internet from home, a digital device such as a laptop is required. Additionally, a modem-router is needed to establish the connection with the Internet service provider. Lastly, a telephone line is necessary to transmit the data signals between the modem-router and the ISP's network. The telephone line serves as the medium through which the Internet connection is established, allowing data to be transmitted and received.

The correct answer is "My mobile phone, What's App Server". This means that the picture is currently present on both my mobile phone and the What's App Server. It suggests that the picture has been sent from my mobile phone to my friend's mobile phone via the What's App Server, which acts as an intermediary in the transmission process.

The picture is in my friend's mobile phone because I sent it to them directly. It is also in my mobile phone because I took the picture and sent it. Additionally, the picture is in the WhatsApp server as it is the platform through which the picture was sent and received.

The explanation for the given answer is that the communication between the client (the program running on the laptop) and the server (the program running in the webserver) is facilitated by software. This software could be a web browser, such as Chrome or Firefox, which allows the client to send requests to the server and receive responses. Additionally, the server-side software, such as PHP, processes these requests and generates the appropriate responses to be sent back to the client. Overall, software plays a crucial role in enabling communication between the client and the server in this scenario.
