Exam Questions and CORRECT Answers
client-server architecture - CORRECT ANSWER - In this type of architecture there is an
always-on host, called the server, which services requests from many other hosts, called clients.
data center - CORRECT ANSWER - Often in a client-server application, a single-server
host is incapable of keeping up with all the requests from clients so for this reason a ____
______, housing a large number of hosts, is often used to create a powerful virtual server.
P2P architecture - CORRECT ANSWER - In this architecture there is minimal or no
reliance on dedicated servers
self-scalability - CORRECT ANSWER - One of the most compelling features of P2P
architectures is their _______________.
socket - CORRECT ANSWER - A software interface which messages are sent into and
messages are received from in the network. Analogous to the doors of a house.
API (Application Programming Interface) - CORRECT ANSWER - sockets are the ___
between the application and the network
IP address - CORRECT ANSWER - In the Internet, the host is identified by its
port number - CORRECT ANSWER - Because a host could be running many network
applications, a destination ____ ______ is needed.
reliable data transfer - CORRECT ANSWER - A type of protocal that provides a
guaranteed data delivery services is said to provide RDT which stands for
, TCP (Transmission control protocol) - CORRECT ANSWER - Protocol is the underlying
layer of HTTP and is said to be a connection-oriented service
SSL (Secure Sockets Layer) - CORRECT ANSWER - An enhancement for TCP providing
security
UDP (User datagram protocol) - CORRECT ANSWER - A no-frills, lightweight transport
protocol, providing minimal services, DNS uses this protocol
Application-layer protocol - CORRECT ANSWER - TCP an UDP are forms of transport
layer protocols, HTTP and SMTP are forms of what protocol (protocol sends messages between
end systems)

layer protocol for electronic mail is
non-persistent connections - CORRECT ANSWER - type of HTTP connections that closes
after each request from the client
persistent connections - CORRECT ANSWER - type of HTTP connections that keeps
connections open after a request to the server
round-trip time - CORRECT ANSWER - RTT is the abbreviation for?
