The ping command in Linux is used to check network connectivity to a specific hostname or IP address. It sends ICMP Echo Request packets and measures response times.

nslookup is used for DNS lookups, not connectivity testing.

ifconfig displays network interface configurations but does not test connectivity.

dig is used for detailed DNS queries.

The Application layer (Layer 7 of the OSI model) includes Hypertext Transfer Protocol (HTTP), which is used for web communication. This layer provides network services directly to applications and users.

Network layer deals with IP addressing and packet routing.

Session layer manages connections but does not include HTTP.

Transport layer ensures reliable data transmission but does not handle application protocols.

Confidentiality ensures that sensitive information is only accessible to authorized individuals. Role-Based Access Control (RBAC) enforces confidentiality by restricting access based on a user's role within an organization, ensuring that only authorized users can view or modify certain data.

Integrity ensures data is not altered improperly.

Availability ensures access to resources but does not manage permissions.

Consistency is not a CIA triad component.

A broadband router is a type of network router that connects multiple computers within a local network while also providing internet access. It functions as a gateway between the local network and the internet by handling data packet transmission and routing. Broadband routers are widely used in small offices and homes because they offer essential networking services, including DHCP, NAT, and sometimes wireless connectivity.

Inter-provider border routers are used by ISPs to route data between different providers and do not serve as an internet gateway for end users.

Subscriber edge routers are typically deployed at the edge of an ISP's network to connect subscriber networks but do not provide full internet routing functionalities.

Core routers operate at the backbone level of a network, facilitating high-speed data transfer but not connecting end-user devices directly.

PIPEDA requires businesses in Canada to protect personal information through security measures and proper disposal practices. This includes secure deletion of personal data when no longer needed to prevent unauthorized access.

Compensating individuals for data sales is not a legal requirement.

Notifying individuals of each data access is unnecessary unless required by a breach.

Disclosing security software is not mandated by PIPEDA.
