Answer:Network connections are how devices communicate with each other and the internet. There are several types, each with its own strengths and weaknesses: - Wired Connections: These use physical cables to transmit data. They're generally faster, more reliable, and more secure than wireless connections. Examples include: - Ethernet: The most common wired connection, using Ethernet cables to connect devices to a router or network switch. This is often used for home networks, offices, and data centers. - Fiber Optic: Uses light signals through thin glass or plastic fibers for extremely high-speed data transmission. This is typically used for long-distance connections and high-bandwidth applications. - Wireless Connections: These use radio waves to transmit data. They are convenient because they don't require physical cables, but they can be slower, less reliable, and less secure than wired connections. Examples include: - Wi-Fi: The most common wireless connection, using radio waves to connect devices to a wireless router. It's widely used in homes, offices, and public places. - Bluetooth: A short-range wireless technology used for connecting devices like smartphones, keyboards, and mice. - Cellular Data (4G, 5G): Uses cellular towers to provide internet access to mobile devices. The speed and reliability of cellular data vary depending on location and network conditions. - Satellite Internet: Uses satellites orbiting the Earth to provide internet access to remote areas where other connections aren't available. It can be expensive and have high latency (delay).
