What is Networking Device?
hello, friends, my name is DINESH KUMAR GUPTA Today I'm going to discussing Networking Device.
First of all, what is Device?
Device:- An equipment that is connected to the network segment is called a device. the networking device is computer hardware used to connect to the network for the transmission of data.
Types of networking device
(1) End-user Device:- that device that is connected to directly to the user or that device that are provided direct services of the user. ex:- computer, printer, scanner etc.
(2) Networking Device:- that device that is connected to the end users or that device that help to transmission data to the end user or help to communicate to the network is called a networking device.
for example:-
NIC (Network Interface Card)
SWITCH
ROUTER
HUB
REPEATER
GATEWAY
BRIDGE
MODAM
FIREWALL etc.
Now I am going to discuss one by one all networking device
NIC
NIC stands for network interface card, sometimes is also known/called by network interface controller, NIC card, Ethernet card, RJ45 and also LAN card.
NIC card act as an interface computer and network cable.
allow the end user device to communicate in the network.
It contains the MAC (Media Access Control) address that has 48 Bit.
It's work on the Data Link Layer of the OSI Model.
It can be Wired and Wireless.
MAC ADDRESS
Stands for Media Access Control.
it also knows as Physical Address or Ethernet Address.
it is unique address on NIC Card
it has a 48-bit address and written in hexadecimal (0-9, A-F)
for example- FF-32-A9-DD-00-12
first 24 bit is Manufacturer ID and next 24 bit is Device ID or Serial ID.
REPEATER
The repeater is a Networking device that is to regenerate the signal or its convert week signal to strong signal.
it has two port first one is the input port and the second is output port.
it works the physical layer of the OSI Model.
HUB
HUB is a networking device that is used to connect or communication the computer or host in a network.
HUB always use Broadcast.
HUB is commonly used to connect segment of LAN.
it has multiple ports when a packet arrive at one port it is copied to the other port so that all segment of the LAN can see all packet.
it works the physical layer of the OSI Model.
Now, it is absolute from the network.
it has multiple ports it can be 4, 8, 16, 24, 42.
Transmission Mode
(1) Simplex:- Data flow in single Direction
(2) Duplex:-
(a) Half Duplex:- one-time data flow
(b) Full Duplex:- both side data flow at the same time.
In HUB transmission mode half-duplex mode.
SWITCH
The switch is a networking device that connects host in a network.
multiple ports to connect the computer or end-user device to communicate with each other.
it's working on the data link layer of the OSI Model.
Is use full duplex mode.
It has a transmission speed of 10 Mbps, 100 Mbps, 10 Gbps.
It contains the MAC Table and CAM table.
First-time use Broadcast and after use always unicast.
It has multiple ports it can be 8, 16, 24, 48, 64, 128.
It uses Star Topology.
ROUTER
A Router is a networking device that is used to transfer the data packet to the different network.
It works on the Network Layer of the OSI Model.
And also used to communicate two different Network.
Work as DHCP Server.
It is also used to access the internet.
It blocks the broadcast.
It used packet filtering Firewall.
GATEWAY
Gateway is a network node which connected two networks in a different protocol.
It acts as an exit point of the network.
It used to communicate two different networks.
MODEM
Modem stands foe modulator-demodulate.
A Modem is a device or programme that enable a computer to transmit data over.
that is used to convert analog signal to digital signal and digital signal to analog signal.
It works on the data link layer of the OSI Model.
BRIDGE
The bridge that used to connect two different LAN segment.
It is used to filter the frame for work it according to the destination.
It works layer 2 (data - link layer) of the OSI Model.
Thanks for reading my tutorials.
