◉ Packet Sniffer. Answer: A passive receiver that records a copy of every
packet within a general vicinity of the object
◉ IP Spoofing. Answer: The act of injecting packets into the Internet with a
false source address
◉ Application Architecture. Answer: Designed by the application developer
and dictates how an application is structured over various end systems
◉ Client-Server Architecture. Answer: Consists of an always-on host that
services requests from many other hosts
◉ P2P Architecture. Answer: Exploits direct communication between pairs of
intermittently connected hosts
,◉ Self-Scalability. Answer: A feature of P2P architectures that implies
increased service capacity with increased users
◉ Process. Answer: A program running within an end system
◉ Socket. Answer: A software interface that receives messages from a process
and then sends those messages into the network; the API between the
application and the network
◉ IP Address. Answer: A 32-bit quantity that uniquely identifies a specific host
◉ Port Number. Answer: A quantity that identifies the receiving process
running in a host
◉ Reliable Data Transfer. Answer: A feature that guarantees that data will be
delivered to its destination
◉ Loss-Tolerant Applications. Answer: Applications such as multimedia
applications that do not require reliable data transfer
◉ Reliable Data Transfer, Throughput, Timing, Security. Answer: Transport
services available to applications
, ◉ Bandwidth-Sensitive Applications. Answer: Applications that have
throughput requirements
◉ Elastic Applications. Answer: Applications that can use as much or as little
throughput as is available
◉ TCP Connection. Answer: Exists between the sockets of two processes after
the handshaking phase
◉ Secure Sockets Layer. Answer: Provides critical process-to-process security
services such as encryption, data integrity, and end-point authentication to
TCP connections
◉ Application-Layer Protocol. Answer: Defines how an application's processes
pass messages between different end systems
◉ HyperText Transfer Protocol. Answer: HTTP
◉ Object. Answer: A file that is addressable by a single URL
