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.
What layer of the OSI model does NAT operate?
Layer 3
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.
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
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.
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.
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.
The application tcp-ip layer maps to which osi layers?
The Application layer The Presentation layer The Session layer
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.
What layer of the OSI model does NAT operate?
Layer 3
The network interface TCP-IP layer maps to which OSI layers?
The data-link layer The physical layer
Routers operate at which osi layer?
3
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
