The HTTP status code 201 indicates that a resource has been successfully created, typically in response to a POST request.

The HTTP status code 404 indicates that a resource was not found on the server.

Class A IP addresses are used for large networks, allowing for a vast number of hosts.

Class A IP addresses are used for large networks, allowing for a significant number of hosts due to their large address space.

Class A IP addresses are used for large networks, allowing for a significant number of hosts.

The IP address 127.0.0.1 is reserved for the loopback interface, allowing a device to communicate with itself.

A switch operates at the Data Link Layer (Layer 2) of the OSI model, forwarding frames based on MAC addresses.

Error detection and correction occur at the Data Link Layer (Layer 2) of the OSI model.

IP addressing operates at the Network Layer (Layer 3) of the OSI model, facilitating routing of packets.

Ethernet operates at the Data Link Layer (Layer 2) of the OSI model.

HTTP (Hypertext Transfer Protocol) operates at the Application Layer (Layer 7) of the OSI model.

The MAC address operates at the Data Link Layer of the OSI model, which is responsible for node-to-node data transfer.

The Data Link Layer is responsible for error detection and correction through mechanisms like checksums and CRC.

The Presentation Layer (Layer 6) is responsible for data encryption and decryption, as well as data formatting.

The Presentation Layer (Layer 6) is responsible for data formatting, encryption, and translation between different data formats.

The Transport Layer (Layer 4) is responsible for end-to-end communication and error recovery, ensuring reliable data transfer.

The Data Link Layer (Layer 2) is responsible for error detection and correction in frames.

The Session Layer (Layer 5) is responsible for establishing, managing, and terminating connections between applications.

The Session Layer (Layer 5) is responsible for establishing, managing, and terminating sessions between applications.

The Network Layer (Layer 3) is responsible for logical addressing, such as IP addresses, to route packets across networks.

The Network Layer is responsible for routing packets between different networks.

The Session Layer is responsible for establishing, maintaining, and terminating sessions between applications.

The Session Layer (Layer 5) is responsible for managing sessions between applications, establishing, maintaining, and terminating connections.

The Application Layer provides services directly to user applications.

The Application Layer of the TCP/IP model corresponds directly to the Application Layer of the OSI model, handling high-level protocols and user interfaces.
