Role of an Access Point (AP):

Wireless to Wired Conversion: An access point (AP) is a device that allows wireless devices to connect to a wired network using Wi-Fi. It converts wireless signals (radio waves) into electronic signals that can be understood by wired network devices.

Functionality:

Signal Conversion: The AP receives wireless signals from devices such as laptops, smartphones, and tablets, converts them into electronic signals, and transmits them over the wired network.

Connectivity: APs provide a bridge between wireless and wired segments of the network, enabling seamless communication.

Comparison with Other Devices:

Router: Directs traffic between different networks and may include built-in AP functionality but is not primarily responsible for converting wireless to electronic signals.

Firewall: Protects the network by controlling incoming and outgoing traffic based on security rules, not involved in signal conversion.

Load Balancer: Distributes network or application traffic across multiple servers to ensure reliability and performance, not involved in signal conversion.

Deployment:

APs are commonly used in environments where wireless connectivity is needed, such as offices, homes, and public spaces. They enhance mobility and provide flexible network access.

Wi-Fi 6E is the best choice for high-density environments, such as a university campus. It:

Supports more devices with OFDMA (Orthogonal Frequency-Division Multiple Access)

Uses the 6GHz band, reducing congestion

Provides faster speeds and lower latency

This makes Wi-Fi 6E ideal for large networks with high-bandwidth demands, like those in a university setting.

Breakdown of Options:

A. Bluetooth – Used for short-range, low-power connections, not large-scale wireless networks.

B. Wi-Fi 6E – ? Correct answer. Designed for high-density environments, improving speed and efficiency.

C. 5G – Used for mobile networks, but not ideal for campus-wide local wireless infrastructure.

D. LTE – Used for cellular data, not for campus-wide Wi-Fi.

SSH (Secure Shell) is a protocol used to securely connect to a remote server/system over a network. It operates on port 22 and provides encrypted communication, unlike Telnet which operates on port 23 and is not secure. TLS is used for securing HTTP connections (HTTPS) and operates on ports like 443, while RDP (Remote Desktop Protocol) is used for remote desktop connections and operates on port 3389.
