Which devices work in the presentation layer?
firewall, router,layer 3 switches and i approve that answer ! NO! In general the firewall is a layer 4 device, it traffics filter incoming and outgoing ports. It uses the function of TCP and UCP. However a Firewall can also be a layer 3 device as in internal firewall in a router. Also a switch is a layer 2 device unless your talking about a Router switch.
7 What connecting device do you use for a small LAN?
It's called a switch. Many wireless routers have a 4-port switch. Also you can purchase a switch separately.
Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
Is the switch an input or output?
In the grand scheme of things it could be called an output device. Also in the same train of thought it could also be called an input device depending on how you look at the overall picture of how it is going to be used.
What is diff between layer 3 switch and router?
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
Diifference between distribution layer switch core layer switch?
Core layer switch forms the heart of the network. it interconnects all the subnetworks formed by distribution switches. It also has special modules such as IDPS. It has very high switching capacity when compared with normal (Access ) Switches. Distribution switch forms the intermediate layer between access and core switch.
What is found on a datalink layer header?
The data link layer header contains the destination and source of information of the original frame and device sending information. You will also find that it contains the information of the device to receive it.
What is difference between L3 switch and router?
A layer 3 switch has routing capability like a router. However, it also has layer 2 switching capabilities like a switch. To fulfill both functions, layer 3 switches will generally have a greater number of ports than most routers.
Which layer of the sun's atmosphere is also called the surface?
The layer of the sun's atmosphere that is also called the surface is the photosphere. This is where most of the visible light is emitted and is the layer that gives the sun its brightness.
What is the difference between a network router and switch?
The difference between a router and a switch has to do with the layers of the OSI model that they reside in. A switch is a layer 2 device, which means it relies on the MAC (physical) address for switching packets. A router is a layer 3 device, using the network (logical) address. A router also can forward packets to another network; a switch does not do that. In addition, a switch forwards all broadcast packets whereas a router does not forward broadcast packets.
What layer of OSI model is switches on?
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
Router is a layer 3 or 4 device if your ans is layer 3 then while applying an extended access list on router interface how specifying port no is aloud as it comes under layer 4 protocols?
A router is a layer 3 device.In general, a Layer-3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities. A router is a Layer-3 device that simply do routing only. In the case of a switching router, it is primarily a router that may use switching technology (high-speed ASICs) for speed and performance (as well as also supporting Layer-2 bridging functions). As illustration, here are some examples Layer-2 switches Cisco: Catalyst 2950, 2960 series Layer-3 switches or routing switches Cisco: Catalyst 3550, 3560, 3750, 4500, 6500 series Juniper: EX series Routers (with some bridging and/or security features) or switching routers Cisco: 1800, 1900, 2600, 2800, 2900, 3700, 3800, 3900, 7200, 7600, ASR 1000 series Juniper: MX series, J series, M series
