Using a /30 subnet mask on a Class B network allows for 1024 subnets, as it borrows 2 bits from the host portion.

Using a subnet mask of 255.255.255.0 on a Class B network allows for 256 subnets.

A /22 subnet mask allows for 2^(22-16) = 2^6 = 64 subnets from a Class B network.

A /22 subnet mask allows for 4 subnets when using the remaining bits for subnetting (2^(32-22) = 4).

The maximum size of a URL in HTTP requests is typically 2048 characters, although this can vary by browser.

Private IP addresses are not routable on the internet, allowing organizations to conserve public IP addresses while using them internally.

The default gateway is used to route traffic from a local subnet to destinations outside that subnet, typically to the internet.

A router's primary function is to forward data packets between different networks, directing traffic efficiently.

A switch filters and forwards frames within the same network, operating primarily at the Data Link Layer.

The 'User-Agent' header identifies the client software making the request, allowing the server to tailor responses accordingly.

ARP (Address Resolution Protocol) is used to resolve IP addresses to their corresponding MAC addresses on a local network.

The Data Link layer is responsible for error detection and correction as well as framing data for transmission.

The primary function of the Network Layer (Layer 3) is to route packets across different networks.

The Physical Layer (Layer 1) is responsible for the transmission of raw bitstreams over a physical medium.

The subnet mask is used to identify which part of an IP address refers to the network and which part refers to the host.

TCP (Transmission Control Protocol) is responsible for data segmentation, ensuring that data is sent and received in manageable pieces.

The primary function of the Transport Layer (Layer 4) is to establish, manage, and terminate connections between applications.

The primary purpose of a router is to route packets between different networks, making decisions based on IP addresses.

A switch connects devices within the same network, using MAC addresses to forward data to the correct destination.

Error control is primarily used to ensure data integrity by detecting and correcting errors in transmitted data.

HTTP methods like GET and POST are used for data retrieval and submission between clients and servers.

Routing is primarily used to determine the best path for data packets to travel across networks, ensuring efficient data delivery.

Subnetting is primarily used to improve network performance and security by dividing a larger network into smaller, manageable segments.

The primary purpose of the ARP (Address Resolution Protocol) is to resolve IP addresses to MAC addresses in a local network.

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

HTTP headers provide metadata about the request or response, such as content type, length, and caching policies.

The primary purpose of the HTTP protocol is to request and transmit web pages between clients and servers.

The HTTP status code 404 indicates that the requested resource could not be found on the server.

The primary purpose of the Link Layer in the TCP/IP model is to provide physical addressing and manage the physical connection.

The primary purpose of the Physical layer (Layer 1) is to transmit raw bitstreams over a physical medium.
