Cards

Term
An architecture model based on the OSI protocol suite, which defines and standardizes the flow of data between computers.
Definition
Open Systems Interconnection (OSI) Seven-Layer Model
Term
An architecture model based on the TCP/IP protocol suite, which defines and standardizes the flow of data between computers.
Definition
TCP/IP Model
Term
An arrangement that governs the procedures used to exchange information between cooperating entities; usually includes how much information is to be sent, how often it is sent, how to recover from transmission errors, and who is to receive the information.
Definition
Protocol
Term
A popular cabling for telephone and networks composed of pairs of wires twisted around each other at specific intervals.
Definition
Unshielded Twisted Pair (UTP)
Term
An electronic device that sits at the center of a star topology network, providing a common point for the connection of network devices.
Definition
Hub
Term
A device that filters and forwards traffic based on some criteria.
Definition
Switch
Term
Traditionally, an expansion card that enables a PC to link physically to a network.
Definition
Network Interface Card (NIC)
Term
The part of a NIC that remembers the NIC's own MAC address and attaches that address to outgoing frames.
Definition
Media Access Control (MAC)
Term
The first 24 bits of a MAC address, assigned to the NIC manufactured by the IEEE.
Definition
Organizationally Unique Identifier (OUI)
Term
The last six digits of a MAC address, identifying the manufacturer's unique serial number for that NIC.
Definition
Devie ID
Term
An address burned into a ROM chip on a NIC. A MAC address is an example of this.
Definition
Physical Address
Term
A defined series of binary data that is the basic container for a discrete amount of data moving across a network. They are created in Layer 2 of the OSI model.
Definition
Frames
Term
A sequence of bits placed in a frame that is used to check the primary data for errors.
Definition
Frame Check Sequence (FCS)
Term
A mathmatical method that is used to check for errors in long streams of transmitted data with high accuracy.
Definition
Cyclic Redundancy Check (CRC)
Term
A frame or packet addressed to all machines, almost always limited to a broadcast domain.
Definition
Broadcast
Term
The address a NIC attaches to a frame when it wants every other NIC on the network to read it.
Definition
Broadcast Address
Term
The aspect of the NIC that talks to the operating system, places data coming from the sofware into frames, and creates the FCS on each frame.
Definition
Logical Link Control (LLC)
Term
A programmable network address, unlike a physical address that is burned into ROM.
Definition
Logical Address
Term
Each independent network in a TCP/IP internetwork.
Definition
Subnet
Term
Special software that exists in every network-capable operating system that acts to create unique identifiers for each system.
Definition
Network Protocol
Term
Part of the TCP/IP suite, operates at Layer 4 (transport) of the OSI seven-layer model.
Definition
Transmission Control Protocol (TCP)
Term
The internet standard protocol that handles the logical naming of the TCP/IP protocol using IP addresses.
Definition
Internet Protocol (IP)
Term
The numeric address of a computer connected to a TCP/IP network, such as the internet.
Definition
IP Address
Term
A device that connects separate networks and forwards a packet from one network to another based only on the network address for the protocol being used.
Definition
Router
Term
Basic component of communication over a network. A group of bits of fixed maximum size and well-defined format that is switched and transmitted as a complete whole through a network.
Definition
Packet
Term
Handles the process of differentiating among various types of connections on a PC.
Definition
Sessions Software
Term
A protocol used by some older applications, most prominently TFTP, to transfer files.
Definition
User Datagram Protocol (UDP)
Term
The connection-oriented payload of an IP packet. Works on the Transport layer.
Definition
TCP Segment
Term
A connectionless networking container used in UDP communication.
Definition
UDP Datagram
