What is ARP And DHCP Protocol, How It Works
Now today in this blog we are gonna talk about two important protocols ARP and DHCP.
ARP: ARP stands for Address Resolution Protocol which is used to associate device MAC address with IP address.
DHCP stands for Dynamic Host Configuration.
DHCP is configured as an IP service on network to automatically provide an available IP address to client devices.

You can check my blog for more details about Arp Protocol and DHCP protocol

LEARN OSI MODEL AND IMPORTANCE OF OSI MODEL IN NETWORKING
If you want to Read More In Detail About it :- https://www.jewkoiyie.com/learn360-osi-model/
-> OSI stands for Open System Interconnection, which was published in 1984 by ISO (International Organization for Standardization).
-> It is a reference model that describes how information from software applications in a computer travels from one physical medium to software applications in another computer. OSI has seven layers, and each layer performs a specific network function.
It Contain 7 Layer in OSI Model :-
7. Physical Layer
6. Data Link Layer
5. Network Layer
4. Transport Layer
3. Session Layer
2. Presentation Layer
1. Application Layer

What is TCP/IP And UDP and Why TCP/IP and UDP
TCP stands for Transmission Control Protocol which works in the transport layer of both the models. TCP protocol is used in transferring data or packet from source to destination and this protocol is connection oriented.

Three way Handshake :-
Three way handshake is nothing but the process of establish a connection between two devices before transmitting the data. So, now let’s see the process.

UDP Protocol :-
UDP stands for User Datagram Protocol , it is a connectionless protocol , this protocol doesn’t care whether packet is reached or not to the destination but TCP protocol does.

Computer Networking – What is Network Security and Devices used in iT.

Network Security :-
Network security is basically used to protect our computer from Unsecure IPs or from Attacker that wants to take over our access, and In Todays world Network Security is very important for all of us. You should know what services is running on your machine so that you will get to aware from remote access shells, trojans, viruses and etc...

Firewall :-
So, Firewall is nothing but a software or you can say hardware networking device which monitors the traffic and block the suspicious or malicious traffic between internal private network and the outside internet.
Types of Firewall :-
1. Host Based Firewall.
2. Network Based Firewall.
3. Next Generation Firewall.

Computer Network – What is Domain Name System ( DNS ).
Domain Name Server :-

DNS stands for Domain Name System, as it is basically used to access resources from the server. As we know every devices is connected to the internet and every device has IPv4 or IPv6 address, similarly server also has IP address again n again, as IP addresses are numbers and numbers are not easy to remember, that's why Domain Name System is introduced which is readable and easy to remember for humans.

Working of DNS :-

1. When we enter any web address like example.com in our browser then our computer firsts checks its local cache if we have visited that particular website recently, if visited then fine if not then a request to the Recursive DNS Server or DNS Resolver is made.

2. ipconfig /displaydns will show you DNS details in windows.

3. The recursive server then queries a DNS root server (.).

4. If we find result at root server then process ends up here.
If we don’t get results here then root server send that particular request to the TLD server who is handing that particular TLD, in
this case it is .com.

5. The TLD server then responds with the IP address of the domain’s name server, example.com .

6. Lastly recursive DNS server sends request to the authoritative nameserver of example.com.

7. Then IP address is returned to recursive DNS server from the authoritative name server.

8. Recursive DNS Server then responds to the web browser with the IP address of the domain requested initially.
