Term
IP
Definition
Internet Protocol- Core protocol in the TCP/Ip suite that operates in the Network layer of the OSI, provides info on how and where data should be delivered
Term

Term
LLC
Definition
Logical Link Layer sublayer- Upper sublayer in the Data Link Layer- provides a common interface and supplies reliability and flow control services.
Term
MAC address
Definition
MEDIA ACCESS CONTROL- 12 character string that identifies the network node- block ID and device ID.
Term
MAC sublayer
Definition
MEDIA ACCESS CONTROL- LOWER sublayer of the data link layer. the MAC appends the physical address of the destination computer onto the frame
Term
MTU
Definition
Maximum Transmission Unit-Largest Data unit a network will accept for transmission.
Term
OSI
Definition
Open Systems Interconnection Model- 7 layer model for UNDERSTANDING and developing computer to computer communication developed in 1980's by ISO.
Term
PDU
Definition
Protocol Data Unit- a unit of data at any layer of the OSI model
Term
SYN
Definition
Synchronization-the packet one node sends to request a connection with another node on the network- syn is 1st packet of 3 of establishing a connection
Term
SYN-ACK
Definition
Synchronization-acknowledgment-Step 2 of 3 in establishing a connection-
Term
TIA
Definition
Telecommunications Industry Association- sub group of EIA that focuses on standards for info technology
Term
Transport Layer
Definition
4th layer of OSI, Ensures data are transferred from point a to b reliably and without errors- flow control, acknowledgment, error correction, segmentation, reassembly, and sequencing
Term
Session Layer
Definition
5th LAYER-establishes and maintains communication between 2 nodes on the network AKA "Traffic Cop".
Term
Presentation Layer
Definition
6th Layer- protocols and presentation, translate between the application and the network.
Term
Physical Layer
Definition
1st Layer of OSI,- protocols in the physical layer generate and detect signals
Term
Network Layer
Definition
3rd Layer- protocols in network layer translate network addresses into their physical counterparts and decide how to route data from the sender to the receiver.
Term
Data Link Layer
Definition
Layer 2 of the OSI- data link bridges the networking media with the network layer. It divides the data it receives from the network layer into frames that can be transmitted by the physical layer.
Term
Application Layer
Definition
7th layer of the OSI model- application layer protocols enable software programs to negotiate formatting, prodedural, security, synchronization, and other requirements with the network.
