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.
What is the full form of ieee standard 802.3?
MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE)
Advantages and disadvantages of mac addressing?
The advantage of MAC addressing is that there is no attachment cost to devices that connect to the network. Its disadvantage, on the other hand, include easy spoofing due to the broadcast nature of the Ethernet.

What are the three most common types of internet addresses?
IP addresses and domain names, URLs, email addresses IP- Identify computers URL- Identify web pages Email- Identify people
What are three characteristics of rock that make up the earth's mantle?
The top layer is the crust, the next layer is the outer core, and the last layer is the inner core.
Which type of bridge would be used to connect an ethernet segment with a token ring segment?
You will need a router. Token Ring and Ethernet refer to two different layer two protocols. You will need a layer three device to encapsulate the data for communication between the two networks. A bridge refers to a layer two device.
What layer does ARP operate at?
ARP is protocol that doesn't fit nicely into the OSI model. It's not a layer two protocol because it utilizes Ethernet_II (Data Link) to get around with broadcast addresses (FF:FF:FF:FF:FF:FF). It's also not a layer three protocol because it doesn't provide routing capabilities. It maps layer 2 addresses to corresponding layer 3 addresses. So you could say it's 2.5. It is encapsulated within Ethernet_II frames.
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
Name three types of ethernet?
10-Mbps Ethernet, 100-Mbps or Fast Ethernet, and 1000-Mbps or Gigabit Ethernet.

What are the three ways a wirless network can be secured?
# with an Ethernet cable
Why do you call router as layer three device?
Routers operate in layer 3 because they must use the logical network address to determine which network to route the packet to. Logical addressing is a feature of layer 3, therefore a router is a layer 3 device.
1 Name three types of Ethernet What transmission speed does each support?
(From: Jean Andrews CompTIA A+ 6th Edition pg. 846) The three variations of Ethernet are primarily distinguished from one another by speed: (1) 10-Mbps Ethernet, (2) 100-Mbps or Fast Ethernet, and (3) 1000-Mbps or Gigabit Ethernet.
