* Definition of GDPR:
* General Data Protection Regulation (GDPR) is a regulation in EU law on data protection and privacy for all individuals within the European Union and the European Economic Area. It also addresses the transfer of personal data outside the EU and EEA areas.
* Scope and Objectives:
* GDPR aims to give individuals control over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU.
* It enforces rules about data protection, requiring companies to protect the personal data and privacy of EU citizens for transactions that occur within EU member states.
* Comparison with Other Options:
* SCADA (Supervisory Control and Data Acquisition): Refers to control systems used in industrial and infrastructure processes, not related to personal data protection.
* SAML (Security Assertion Markup Language): A standard for exchanging authentication and authorization data between parties, not specifically for personal data protection.
* PCI DSS (Payment Card Industry Data Security Standard): A set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment, not specific to personal data protection in Europe.
* Key Provisions:
* GDPR includes provisions for data processing, data subject rights, obligations of data controllers and processors, and penalties for non-compliance.

An access point (AP) provides users with an extended footprint that allows connections from multiple devices within a designated Wireless Local Area Network (WLAN).
Router: Typically used to connect different networks, not specifically for extending wireless coverage.
Switch: Used to connect devices within a wired network, not for providing wireless access.
Access Point (AP): Extends wireless network coverage, allowing multiple wireless devices to connect to the network.
Firewall: Primarily used for network security, controlling incoming and outgoing traffic based on security rules, not for providing wireless connectivity.

To create three subnets with at least 30 hosts each:
Subnet Calculation: Each subnet must support 32 addresses (30 usable + 2 reserved for network and broadcast).
Bits for Subnets: Subnet mask 255.255.255.192 (/26) provides 64 addresses per subnet (4 subnets total).
Valid Subnets: Each subnet provides sufficient IPs to meet the requirement.
255.255.255.128 (A): Creates only 2 subnets, not enough for the requirement.
255.255.255.224 (C): Provides 8 subnets but only 30 addresses per subnet (28 usable), insufficient for hosts.
255.255.255.240 (D): Too restrictive, only 16 addresses per subnet (14 usable).

An ad hoc topology creates a direct, point-to-point wireless connection between two devices without requiring any central access point or infrastructure.
