A router connects networks together. Routers operate at the networking level of the TCP/IP protocol stack. On Home networks the router is responsible for connecting the home network to the Internet and provides several important networking services like: DHCP.
What device connects networks?
5. Routers – A router is a device like a switch that routes data packets based on their IP addresses. The router is mainly a Network Layer device. Routers normally connect LANs and WANs together and have a dynamically updating routing table based on which they make decisions on routing the data packets.

What is difference between hub and switch?
KEY DIFFERENCES
A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network . A Hub operates on the physical layer, whereas Switch operates on the data link layer.
Which device is called intelligent device in networking?
Explanation: network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
Is switch a networking device?
Switches are networking devices operating at layer 2 or a data link layer of the OSI model. They connect devices in a network and use packet switching to send, receive or forward data packets or data frames over the network. A switch has many ports, to which computers are plugged in.
What is switch router and hub?
A switch transmits data from one device to another in form of frames while a router transmits data from one network to another in form of packets. A hub transmits data from one device to another in form of binary bits.
What is a Level 3 network?
Layer 3 is the network layer and its protocol is the Internet Protocol or IP. ... Traditionally, the network device most associated with Layer 3 has been the router, which allows you to connect devices in different IP networks.
What is Layer 3 routing?
Simply put, a layer 3 switch combines the functionality of a switch and a router . It acts as a switch to connect devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence built into it to double up as a router. ... This is how a layer 3 switch acts as both a switch and a router.
Is a PC a Layer 3 device?
For a PC to be considered a Layer 3 device it would have to make all it's decisions based on L3 information such as IP-addresses.
Is UDP an IP?
UDP is an alternative to Transmission Control Protocol (TCP). Both UDP and TCP run on top of IP and are sometimes referred to as UDP/IP or TCP/IP. ... On the other hand, UDP sends messages, called datagrams, and is considered a best-effort mode of communications.
What network devices operate at OSI Layer 2?
The devices that operate at the Network Access layer include Layer 2 switches and bridges (operating on the Data Link layer) and Layer 1 hubs and repeaters (operating on the Physical layer).
What is Ethernet connection?
Ethernet is a way of connecting computers and other network devices in a physical space . This is often referred to as a local area network or LAN. The idea of an Ethernet network is that computers and other devices can share files, information and data between each other efficiently. Ethernet was released in 1980.
Is a router a Layer 1 device?
Bridges and Switches are considered Layer 2 devices while routers are considered Layer 3 devices . Network Interface Card or NICs operate at Layer 2 of the OSI model.
What does a multilayer switch do?
A multilayer switch is a network device that has the ability to operate at higher layers of the OSI reference model , unlike the Data Link Layer (DLL) traditionally used by switches. A multilayer switch can perform the functions of a switch as well as that of a router at incredibly fast speeds.
What is L2 network connectivity?
Layer 2 refers to the data link layer of the network . This is how data moves across the physical links in your network. It's how switches within your network talk to one another. Installing Layer 2 on your infrastructure gives you high-speed connectivity between devices.
Which of the following devices is not a networking device?
(C) CPU is not a network device.
Is the LAN connected to Internet?
A LAN does not require Internet access , however, and its sole purpose can be to transfer files easily between computers that are within close, relative proximity to one another, or to share printers, fax machines or other hardware.

What does LAN stand for?
A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi.
What is repeater router?
A Wi-Fi repeater, extender, or booster is a device that forwards wireless signals from the router to cover a larger area , such as multiple floors of a house. The repeater creates a new network based on signals from the originating network, and the clients that connect to the repeater are thus on a separate network.
