Ex.1 Answer the questions: 1. Is broadband quicker than an ordinary Internet connection? 2. How do you pay for a broadband connection? 3. What are the limits of wireless technology? 4. Has 3G technology been completely developed yet? 5. What will you be able to do with 3G technology on your mobile? 6. What is Wi-Fi? 7. How far can Wi-Fi signals travel?

Answer and Explanation:

1. Broadband is, in fact, faster than a regular internet connection. That's because broadband was designed to be a high speed connection, so it is competitive over common and most popular connections. The speed of broadband is the main reason why it is the most desired internet connection and also the most expensive in relation to the others.

2. In order to pay for a broadband connection, the user must contact a broadband internet provider. Once this contact is established, payment methods will be negotiated.

3. As wireless technology does not have wires, it presents a limitation that can be very uncomfortable for users, which is the presentation of interference with other connections present in the same area. This interference can impair the use of this technology because it can literally drop the signal and prevent the user from using the connection.

4. 3G technology has already been fully developed and is currently out of date, as more efficient technologies such as 4G and even 6G present a more efficient and satisfactory connection.

5. With 3G technology it allows the user to reply and view some text messages for a limited time. Viewing images, videos, social networks and any other media is difficult with this type of technology, which makes its use a major disadvantage.

6. Wi-Fi is a wireless communication technology that allows multiple devices to access the internet at the same time and can enjoy unlimited internet at any time, when their access to that network is allowed.

7. when it comes to home networks, it is common for Wi-Fi to be able to reach between 46 - 92 meters. This depends on the type of network, the capacity of the router and the nature of the environment that may be internal or external.
