Application Layer

In a client-server application, the server is characterized by:

A process is fully identified on the Internet by:

Which transport service does TCP provide that UDP does NOT?

SSL provides all of the following EXCEPT:

A web page has a base HTML file plus 3 referenced objects. With non-persistent HTTP fetched sequentially and RTT = 100 ms (ignore transmission time), the total time is about:

With non-persistent HTTP, retrieving one object takes approximately:

Cookies exist mainly because HTTP is:

FTP uses two parallel TCP connections; the control connection uses port:

SMTP transfers email between mail servers using TCP on port:

Which DNS server type holds the authoritative host-to-IP records for an organization's own hosts?

Application code runs on end systems, not on network-core devices.

In P2P architecture there is always an always-on central server.

A socket is the interface between the application process and the transport layer.

UDP guarantees reliable, in-order delivery of data.

Persistent HTTP can send multiple objects over a single TCP connection.

A Web cache (proxy) acts as both a client and a server.

FTP sends its commands and its file data over the same single connection.

SMTP is a 'push' protocol used to send mail toward the receiver's server.

With IMAP, messages are kept and organized on the server across sessions.

DNS is implemented as a single centralized database for the whole Internet.

Match each application with its transport protocol/port.

Match each transport protocol/property.

Match each email protocol/component with its role.

Match each DNS server type with its responsibility.

Match each Web/architecture concept.
