Employees of a company connect their wireless laptop computers to the enterprise LAN via wireless access points that are cabled to the Ethernet ports of switches At which layer of the three-layer hie?
access level
Which layer 2 portocol could be used inside network A nd C?
The layer 2 protocol that could be used inside of network A and network C is ethernet. Ethernet is a family of computer networking technologies for local area networks.
Where does Ethernet protocol align in the osi model?
Ethernet is a data link layer protocol - layer 2
Why does Ethernet cannot provide www service?
WWW service is work onApplication layer & Ethernet is datalink layer protocol.
How many bits are there in a data link layer Ethernet address?
How many bits are there in a data link layer ethernet address?
Routers operate at layer LAN switches operate at layer Ethernet hubs operate at layer?
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Why switch is data link layer?
Data link layer refers to things that happen within a single network; that's what a switch does. Only a router (or equivalent device, which I would still consider a "router") is able to connect different networks.The different networks may use the same technology (for example, Ethernet and Ethernet), or different technologies (for example, Ethernet and Wi-Fi); a switch is only able to connect parts of a single network that use the same technology (often this will be Ethernet).
What is an Ethernet switch and where does it fit into the OSI model?
Ethernet switch fits on osi physical layer
Is a router box the same as a Ethernet?
No, they are not the same. A router can connect several Ethernet networks together. Ethernet is the name of a layer 2 protocol.

What is wireless card?
a "wireless card" is a network card that receives a high frequency signal from a wireless router or wireless access point. Same as an Ethernet Card/Network Interface Card(NIC), only wireless. A wireless Card is a network card which connects to a radio-based computer network, unlike a regular network interface controller (NIC) which connects to a wire-based network such as token ring or ethernet. A wireless Card, just like a NIC, works on the Layer 1 and Layer 2 of the OSI Model. A wireless Card is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A wireless Card in a desktop computer usually is connected using the PCI bus. Other connectivity options are USB and PC card. Integrated WNIC's are also available, (typically in Mini PCI/PCI Express Mini Card form).
Why are Ethernet II frames preferred over Ethernet 802.3 frames on contemporay lans?
They can support multiple higher-layer protocols, and Ethernet 802.3 frames cannot.
