5.1 Name a device that connects a LAN to a WAN - NSC Computer Application Technology - Question 5 - 2017 - Paper 2

1. Speed of data transfer is slow: Bluetooth connections are significantly slower compared to wired connections or Wi-Fi, making them less suitable for large data transfers.

2. Range is limited: Bluetooth has a range of about up to 100 meters, which restricts how far devices can be from each other.

1. High bandwidth costs: The costs associated with data transfer over the internet can become significant, especially for large volumes of data.

2. Security issues: Storing sensitive data on the cloud may raise concerns about data breaches and unauthorized access.

Wi-Fi is a common technology that uses radio waves for wireless data transfer.

A network switch connects two or more computers/devices in a network and directs network traffic data efficiently.

1. Unable to access folders/data/files: Users may be restricted from accessing certain files or directories on the network.

2. Cannot install software: Users may lack permission to install new software applications on their devices.

A web browser is typically required to access a company's intranet.

An example of a VoIP program, other than Skype, is WhatsApp.

Using VoIP for emergency calls can be unreliable due to issues like internet connection instability and difficulty in tracing the origin of the call.

A user might reduce the quality of VoIP calls to prevent dropped calls and save on data costs.

1. Connect speakers via Bluetooth: Users can use Bluetooth speakers to listen to music wirelessly.

2. Use USB cable: Music can also be listened to by connecting the smartphone to speakers using a USB cable.
