Cards

Term
Ethernet
Definition
____ is a set of networking technologies and media access methods specified for LANs. It allows computers to communicate over small distances using a wired medium.

Term
Start-of-Frame Delimiter (SFD)
Definition
The ____ identifies the beginning of the data field in an ethernet frame.
Term
Destination Address (DA)
Definition
The ____ is the MAC address of the computer to which the frame is being transmitted; it can be a unicast, multicast, or broadcast address.
Term
Source Address (SA)
Definition
The ____ is the MAC address of the computer transmitting data; it is always a unicast address.
Term
Frame type
Definition
The ____ is the length of the entire Ethernet frame in bytes, or the frame type ID of the frame. This field can hold a value between 0 and 65,534, but the maximum value is usually less than 1500.
Term
Data
Definition
The _____ is payload of the frame (or the information being sent). It must be a minimum of 46 bytes long and can be a maximum of 1500 bytes.
Term
Frame Check Sequence (FCS)
Definition
The ____ checks the frame using a 32–bit Cyclic Redundancy Check (CRC) value. The FCS allows the receiving device to detect errors in the Ethernet frame and reject it if it appears damaged.
Term
MAC address
Definition
A ___, also called a physical address, is a unique, hardware-level address assigned to every networking device by its manufacturer.
Term
International Organization for Standardization (ISO)
Definition
_____ is a non-governmental organization issuing voluntary standards in fields from agriculture to textiles. In 1984 it developed a reference model called the Open Systems Interconnection (OSI) model.
Term
Institute of Electrical and Electronics Engineers (IEEE)
Definition
____ is an organization dedicated to advancing theory and technology in electrical sciences.
Term
American National Standards Institute (ANSI)
Definition
____ is the national standards institute of the United States that facilitates the formation of a variety of national standards, as well as promoting those standards internationally.
Term
Telecommunications Industry Association, and Electronic Industries Alliance (TIA and EIA)
Definition
____ are two trade associations accredited by ANSI to develop and jointly issue standards for telecommunications and electronics.
Term
The Internet Engineering Task Force (IETF)
Definition
____ international open committee, consists of working groups, committees, and commercial organizations that work together to develop and maintain Internet standards and contribute to the evolution and operation of the Internet. Publiahes all Requests for Comments (RFCs).
Term
802.2 standard
Definition
The ____ specifies the frame size and transmission rate. Frames can be sent over Ethernet and Token ring networks using either copper or fiber media.
Term

Term
802.3j
Definition
The ____ specification applies to Fiber with a max distance of 2000 meters. It als known as the 10Base-F standard.
Term
Token ring
Definition
_____ is a type of technology used on ring networks in which computers pass a special sequence of bits called a token between them. Only the node holding the token can transmit on the network.
Term
Fiber Distributed Data Interface (FDDI)
Definition
The _____ is a type of technology used on ring networks and uses single mode or multi mode fiber that transmits data at a rate of 100 Mbps.
Term

_____ is a device that connects an IEEE 802.11 conformant MAC interface to a wireless medium with an Ethernet-like driver interface.
Term
Access Point (AP)
Definition
The ____ functions as a bridge between wireless STAs and the existing network backbone for network access.
Term
Distribution System (DS)
Definition
_____ is a wired connection between a BSS and a premise-wide network that enables mobility to devices and provides access to available network resources.
Term
Basic Service Set (BSS)
Definition
The ____ defines the way a WLAN is configured.
Term
Extended Service Set (ESS)
Definition
_____ is a configuration of multiple BSSs used to handle mobility on a wireless network.
Term
Independent Basic Service Set (IBSS)
Definition
____ is a peer-to-peer network where each wireless station acts as both a client and a wireless AP. Each wireless station can both transmit and receive data.
Term
