Term
|
Definition
| describes the frame type, as well as the protocols and security method used in the transmission |
|
|
Term
|
Definition
| specifies the duration within which the next frame should be received |
|
|
Term
|
Definition
| specify media access control or MAC, addresses-for the source node, a transmitter, a receiver or another intermediary device like an AP, and the destination node |
|
|
Term
|
Definition
| indicates where the frame fits within a sequence of frames that constitute a single message |
|
|
Term
|
Definition
| contains the data that the sending node needs to transmit |
|
|
Term
|
Definition
| contains a value that the recipient can use to check the integrity of the transmitted data |
|
|
Term
| Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) |
|
Definition
| 8021.11 based wireless networks use an access method to reduce he potential for collisions |
|
|
Term
| The CSMA/CA access method includes several steps: 1.preparing data to transmit |
|
Definition
| the access method starts when a client node has data for a transceiver to transmit |
|
|
Term
| The CSMA/CA access method includes several steps: 2. checking if the network is free |
|
Definition
| Once a client has data to transmit its network interface card, checks if another transmission is in progress. if a transmission is in progress, the NIC waits a predetermined time and then checks the network medium again |
|
|
Term
| The CSMA/CA access method includes several steps: 3. sending a jamming signal and waiting |
|
Definition
| if the network medium is free, the client's NIC sends a jamming signal, which indicates its intention to transmit a signal |
|
|
Term
| The CSMA/CA access method includes several steps: 4. transmitting data |
|
Definition
| after sending a jam signal and waiting for a specified period, the client NIC sends its transmission |
|
|
Term
| The CSMA/CA access method includes several steps: 5. checking for jamming signals |
|
Definition
| while transmitting data, the NIC listens for other NIC's jamming signals, which could indicate that other nodes tried to transmit data at the same time as it |
|
|
Term
| The CSMA/CA access method includes several steps: 6. listening for an ACK packet |
|
Definition
| after transmitting data, the NIC listens for an ACK packet, which indicates that the destination node received the whole transmission. if no packet arrives the , NIC starts the process again |
|
|
Term
|
Definition
| in this process, the AP and the client identify one another, and the client logs on to the network |
|
|
Term
|
Definition
| all the clients devices that connect to a WLAN using a particular AP |
|
|
Term
| service set identifier, SSID |
|
Definition
| This is the unique name used to identify the WLAN from other WLANs that broadcast in the same area |
|
|
Term
| extended service set, ESS |
|
Definition
| full group of participants in a large WLAN that includes more than one AP with the same SSID |
|
|
Term
| extended service set identifier, ESSID |
|
Definition
| is the common SSID given to the APs in a network that's large enough to require more than one access point |
