Three Threats to Wireless Transmissions

• Eavesdropping: Unauthorized data interception can capture sensitive information due to weak encryption or unsecured networks.

• Man-in-the-Middle Attacks: Attackers alter communication between parties without their knowledge, risking data breaches and compromised information.

• Denial of Service (DoS) Attacks: Networks are flooded with excessive traffic, causing outages and degrading performance.

Wireless Technologies

• Bluetooth: Short-range technology for data exchange between devices, commonly used for peripherals.

• NFC (Near Field Communication): Protocols for close-proximity communication, used in contactless payments and data exchange.

• WLAN: Wireless network for localized connectivity using radio waves.

Drivers for Mobile Computing

• Portability: Access information on the go.

• Connectivity: High-speed internet access via wireless technologies.

• Productivity: Efficient work and communication with mobile devices.

Definition of IoT

• IoT (Internet of Things): Network of interconnected devices that communicate over the internet to enable automation and decision-making.

Advantages and Disadvantages of IoT

• Advantages: Automation, data-driven insights, enhanced connectivity.

• Disadvantages: Security risks, privacy concerns, interoperability issues.

Wireless Transmission Media

• Radio Waves: Wide coverage with penetration capabilities, but suffer from interference and limited bandwidth.

• Microwaves: High bandwidth with focused transmission but require line-of-sight and are sensitive to weather.
