A computer provides several network services, and a client requests one of them. What helps deliver the request to the intended service?

A
The request is delivered to the correct service because all services use the same address.
B
Protocols and addressing information help the request reach the correct service.
C
The client and server must be different kinds of hardware.
D
The request reaches the service because the server removes all headers before receiving it.

A browser sends a request for a webpage to a web service. Which statement correctly identifies the browser’s role in this exchange?

A
The browser is the server because it displays the page.
B
The browser is the client because it requests the page.
C
The web server is the client because it sends data.
D
Both programs are clients because they exchange data.

In the four-layer TCP/IP model, which layer supports communication between applications on hosts and can distinguish the applications at the endpoints?

A
The Application layer, because it forwards packets between networks.
B
The Link layer, because it distinguishes applications at the endpoints.
C
The Transport layer, because it supports communication between applications on hosts.
D
The Internet layer, because it provides services directly to network applications.

A destination host is on a different network from the sender. Which description best explains how the packet can reach it?

A
Routers forward IP packets between networks, and packets may take different routes.
B
A packet establishes a permanent connection that fixes the route between devices.
C
The local link sends every packet directly to its final destination without forwarding.
D
Servers choose a single permanent route that all packets must follow.

A device sends data across its directly connected local network. Which statement correctly describes the relationship between the local-link frame and the IP packet?

A
The IP packet is the local-link unit, and the frame is the TCP unit.
B
The UDP datagram is the IP unit, and the segment is the local-link unit.
C
The frame is the application unit, and the IP packet is the transport unit.
D
The frame is transmitted over the local link, and the IP packet is carried within it.
