Explanation:

For Question 4:

• Internet is a global wide-area network, not short-range device-to-device exchange.
• Bluetooth is designed specifically for short-range (typically up to 10-100 meters) wireless data exchange between nearby devices.
• GPS is for location tracking, not data exchange.
• FTP is a protocol for transferring files over networks, not short-range device-to-device.

For Question 5:

• RSS (Really Simple Syndication) feeds aggregate and deliver updated content from multiple websites to users in a standardized format.
• It is not used for video streaming, phone calls, or email sending.

For Open Ended Question 1:

VoIP (Voice over Internet Protocol) transmits voice data over internet or IP-based networks, while traditional phone services use dedicated circuit-switched telephone networks. VoIP often offers lower costs, integrated features like video calling and screen sharing, and works on internet-connected devices, whereas traditional services rely on physical phone lines and have more limited built-in features.

For Open Ended Question 2:

GPS (Global Positioning System) is widely used for navigation in cars, smartphones, and other devices to provide real-time directions to destinations. It also powers ride-sharing apps to match drivers and passengers, helps with package delivery route optimization, enables fitness trackers to log distance and location during workouts, and supports emergency services to locate people in need.

For Open Ended Question 3:

Wireless internet access points eliminate the need for physical Ethernet cables, allowing users to connect devices like laptops, phones, and tablets to the internet from anywhere within the signal range, increasing mobility and flexibility. They also support multiple devices connecting simultaneously, reduce clutter from cables, and can be easily expanded to cover larger areas by adding more access points, making them ideal for public spaces, offices, and homes.

Answer:

2. B) Receiving updates from websites
3. VoIP transmits voice over internet/IP networks, while traditional phone services use dedicated circuit-switched telephone networks; VoIP offers lower costs, integrated digital features, and works on internet-connected devices, unlike traditional services that rely on physical lines with limited built-in features.
4. GPS is used for real-time navigation in cars and smartphones, powers ride-sharing app location matching, optimizes package delivery routes, tracks fitness activity location and distance, and helps emergency services locate people in need.
5. Wireless internet access points provide mobility by allowing device connections without Ethernet cables, support simultaneous connections from multiple devices, reduce cable clutter, and can be easily expanded to cover larger areas, making them suitable for homes, offices, and public spaces.
