CPRE 230 Final Exam || with Complete Solution.
Physical Layer correct answers Sends bits on a wire or through wireless transmission
Data Link Layer correct answers MAC address
Organizationally Unique Identifier (OUI) correct answers The first 24 bits of a MAC address,
assigned to the NIC manufacturer by the IEEE.
Device ID assigned by manufacturer correct answers Last 24 bits of MAC address
Network Layer correct answers Moves messages from node to node using IP addresses
Transport Layer correct answers Transports application layer payloads from one application to
another. Uses TCP and UDP.
Transmission Control Protocol (TCP) correct answers A connection-oriented Transport-layer
protocol designed for reliable transfer of information.
User Datagram Protocol (UDP) correct answers A connectionless transport protocol. Does not
guarantee delivery by first connecting and checking data is received
Session Layer correct answers Describes how data between applications are synched and
recovered if messages don't arrive intact at the receiving application. Uses SSL/TLS.
Presentation Layer correct answers Responsible for reformatting, compressing, or encrypting
data in a way that the receiving application can read.
Application Layer correct answers Describes the interface between two applications on separate
computers.
, OSI Model correct answers Physical, Data Link, Network, Transport, Session, Presentation,
