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

1. The speed of data transfer is generally slow, making it unsuitable for larger files or high-bandwidth applications.

2. Bluetooth connections have a limited range, typically up to 100 meters, which can restrict the mobility of devices.

1. High bandwidth costs associated with uploading large amounts of data, which can become expensive.

2. Potential security issues involved in storing sensitive data on cloud platforms.
