What else can I help you with?
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.
Which two layers of the OSI model does a WAN operate?
According to Cisco Curriculum Semester 4 1.2.1.1 As described in relation to the OSI reference model, WAN operations focus primarily on Layer 1 and Layer 2. WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
What layer of the OSI model does NAT operate?
Layer 3
A non routable protocol does not operate in which layer of the OSI model?
Network Layer
What layer 2 Transmission Control Protocol?
TCP, the Transmission Control Protocol, is a layer-4 protocol (in the 7-layer OSI model).
Devices found in each OSI model?
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
Does TCP operate at the transport layer?
TCP operates at transport layer
TCP and UDP reside at which layer of the OSI model?
UDP or User Datagram Protocol works on the Transport Layer (layer 4) in the OSI model.
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.
Which one is the best model between osi and tcpip and why?
TCP/IP because the osi model has seven layer but in tcp/ip only four layers and most important is that the tcp/ip model is reduce the function of osi model.
If a firewall does nothing more than filter packets at what layer of the OSI model does it operate?
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.
The application tcp-ip layer maps to which osi layers?
The Application layer The Presentation layer The Session 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.

WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
How many layer of tcp ip?
The TCP/IP model was adopted and condensed into 4 Layers.1. Link layer ( Layer 1and 2 of the OSI model)2. Internet Layer (Layer 3 of the OSI model)3. Transport ( Layer 4, 5 and 6 of the OSI model)4. Application ( Layer 7 of the OSI model)http://en.wikipedia.org/wiki/TCP/IP_model#Link_Layer
The network interface TCP-IP layer maps to which OSI layers?
The data-link layer The physical layer
Does SSL operate at the transport layer or application layer?
I've always considered it to operate at the transport layer as it;s simply an encrypted version of TCP. However, Wikipedia OSI-model lists it as operating at the presentation layer, as it's concerned with the transformation of data between the application and transport layers.
