At which layer does a WAP operate?

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.

Which layer does a bridge operate?

Bridge operate on data link layer

Switches operate at layer and Hubs operate at layer of OSI model?

Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.

What layer does netbeui operate at?

The Transport Layer

Connectivity devices such as hubs and repeaters operate at which layer?

Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.

What layer of the OSI model does NAT operate?

Layer 3

What do you mean by WAP explain WAP architecture with diagram?

WAP is designed in a layered fashion so that it can be extensible,flexible, and scalable. As a result, the WAP protocol stack is divided into five layers:Application LayerWireless Application Environment (WAE). This layer is of most interest to content developers because it contains, among other things, device specifications and the content development programming languages, WML and WMLScript.Session LayerWireless Session Protocol (WSP). Unlike HTTP, WSP has been designed by the WAP Forum to provide fast connection suspension and reconnection.Transaction LayerWireless Transaction Protocol (WTP). The WTP runs on top of a datagram service such as User Datagram Protocol (UDP) and is part of the standard suite of TCP/IP protocols used to provide a simplified protocol suitable for low bandwidth wireless stations.Security LayerWireless Transport Layer Security (WTLS). WTLS incorporates security features that are based upon the established Transport Layer Security (TLS) protocol standard. It includes data integrity checks, privacy, service denial, and authentication services.Transport LayerWireless Datagram Protocol (WDP). The WDP allows WAP to be bearer-independent by adapting the transport layer of the underlying bearer. The WDP presents a consistent data format to the higher layers of the WAP protocol stack, thereby offering the advantage of bearer independence to application developers.Each of these layers provides a well-defined interface to the layer above it. This means that the internal workings of any layer are transparent or invisible to the layers above it. The layered architecture allows other applications and services to utilise the features provided by the WAP-stack as well. This makes it possible to use the WAP-stack for services and applications that currently are not specified by WAP.
