A subnet mask of 255.255.255.252 allows for 2 usable IP addresses (4 total - 2 for network and broadcast), which is suitable for point-to-point links.

A /20 subnet mask corresponds to 255.255.240.0, allowing for 4096 addresses in the subnet.

A /18 subnet mask allows for 2^(32-18) = 16384 total addresses, of which 16382 are usable for hosts.

HTTP operates at the Application layer of the OSI model, which is responsible for providing network services to end-user applications.

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

The Transport Layer (Layer 4) is responsible for end-to-end communication and ensures complete data transfer.

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

The Transport Layer in the TCP/IP model corresponds directly to the Transport Layer of the OSI model.

HTTP uses URL addressing to identify resources on the web.

IPv4 uses logical addressing, which allows devices to communicate over a network using IP addresses.

The Data Link layer uses MAC Addressing to identify devices on the same local network.

The Network Layer uses IP addressing to identify devices on a network.

The Network Layer uses logical addresses (such as IP addresses) to identify devices on a network.

The Network Layer uses logical addressing, such as IP addresses, to identify devices on a network.

The Data Link layer uses MAC Addressing to identify devices on the same local network.

IP addressing is used at the Network Layer (Layer 3) of the OSI model for routing packets.

Fiber Optic Cable is commonly used for high-speed data transmission due to its high bandwidth and low attenuation.

Fiber Optic Cable is commonly used for high-speed data transmission due to its high bandwidth and low attenuation.

TCP uses an acknowledgment mechanism to ensure that packets are received correctly and to request retransmission if necessary.

Fiber Optic Cable uses light to transmit data, allowing for high-speed and long-distance communication.

Logical Addressing is used in the Internet Protocol (IP) to identify devices on a network uniquely.

IP Addressing is used in the Network Layer (Layer 3) of the OSI model to identify devices on a network.

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

The GET method is considered idempotent and safe, meaning it can be called multiple times without changing the state of the resource.

The PUT method is idempotent, meaning that making the same request multiple times will not change the outcome beyond the initial application.

The GET method is used to request data from a specified resource on the server.

The GET method is used to request data from a specified resource, allowing clients to retrieve information from the server.

The GET method is used to retrieve data from a server, while POST is used to send data to the server.

The POST method is used to submit data to a specified resource for processing.

HTTP status code 200 indicates that the request was successful and the server returned the requested resource.
