Lesson 3 : Network Communication Protocols Flashcards
Describes the rules that govern the transmission of data over Communication Network
Network Protocols
Determine when to speak, how fast or slow to talk, and how long to wait for a response.
Message Timing
Determines when someone is able to send a message.
Access Method
How much information can be sent and the speed that it can be delivered.
Flow Control
Response within an acceptable amount of time.
Response Timeout
The special set of rules that end points in a telecommunication connection use
when they communicate.
Network Protocol
Communication between two network endpoints in which a message can be sent
from one end point to another without prior arrangement.
The device at one end of the communication transmits data to the other, without first ensuring that the recipient is available and ready to receive the data.
Connectionless/Stateless Protocols
Set of protocols developed to allow cooperating computers to share resources across a network.
TCP/IP
Responsible for breaking data down into small packets before they can be sent over a network, and for assembling the packets again when they arrived to the destination.
TCP - Transmission Control Protocol
Takes care of the communication between computers. It is responsible for addressing, sending and receiving the data packets over the Internet.
IP - Internet Protocol
Collection of rules and procedures for two computers to exchange information
Defines the format of data being exchanged.
Protocol
TCP/IP key Features
Logical addressing
Routability
Name resolution
Multiplexing
Interoperability
The address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program.
Logical Addressing
Allows packets to be forwarded from one network to another, which at home is
between the user’s local network and the Internet. The global standard routable
protocol is TCP/IP.
Routability
Used to resolve a human readable name
(also known as Fully Qualified Domain Names (FQDN)) to an IP address and vice
versa.
Name Resolution
Can work in a heterogeneous network. TCP/IP eliminates the cross-platform
boundaries.
Interoperability
Accepting data from different applications and directing that data to different
applications listening on different receiving computers
Multiplexing
An endpoint of communication in an operating system.
Always associated with an IP address of a host and the protocol type of the
communication, and thus completes the destination or origination address of a
communication session.
Port
A logical and conceptual model that defines network communication used by systems open to interconnection and communication with
other systems.
OSI Model
A routable protocol responsible for IP addressing, routing,
and the fragmentation and reassembly of packets.
Internet Protocol (IP)
Responsible for the resolution of the Internet layer address to the Network Interface layer address such as a hardware address.
Address Resolution Protocol (ARP)
Responsible for providing the
Application layer with session and datagram communication services.
Transport layer
