The Data Link Layer.............
All 802.x map to 1. Data Link 2. Physical layer in OSI model.
The IEEE was started at February, 1980. So they started to name their standard as 802 such as 802.2, 802.3,802.11 .... 802 - 80 Represents the year when they started 2 - Represents the month
According to IEEE the 802STANDARD is used for LAN Standard.
802.1 Actually, I think the answer is 802.3.
802.5
802.5
transport layer
physical layer
fourth layer
The factors of 802 are: 1 2 401 802
yes 802n works with 802 a/b and g
A firewall generally works at layer 3 and 4 of the OSI model. Layer 3 is the Network Layer where IP works and Layer 4 is the Transport Layer, where TCP and UDP function. Many firewalls today have advanced up the OSI layers and can even understand Layer 7 - the Application Layer.
