What is TCP/IP?
TCP/IP is a group of protocols designed to piece of occupation together to send information across the Network. It was created yesteryear the division of defence inwards the 1970s. TCP/IP is made of ii major protocols
1) TCP (Transmission Control Protocol)
2) IP (Internet Protocol)
TCP/IP (Transmission Control Protocol/Internet Protocol) is a reduced version of OSI Model, Where OSI is non based on a existent network piece TCP/IP is based on the existent network. It is an opened upwardly protocol suite in addition to gratuitous to use. That's hateful novel protocol tin last freely developed every bit needed.[3]
What does it do?
TCP/IP too incorporate about other large set out of protocols that are able to behavior many dissimilar Network functions. The role of TCP/IP is allowing networking device (Router, Switch, Bridge etc) to communicate alongside each other. These protocols define rules for networking device to communicate alongside correct devices.
TCP/IP Layers in addition to Protocols
TCP/IP is consist of Four Layers in addition to all TCP/IP protocols are located on the locomote yesteryear 3 layer in addition to protocols located on a bottom layer are non portion of the TCP/IP. Application Layer, Transport Layer, Internet Layer in addition to Network Layer.Application Layer
In this layer, nosotros define Protocols, Services, in addition to Process that let programs in addition to users to interface alongside the network. It too defines how programs interface alongside the carry layer service to usage the network.
HTTP
Hyper Text Transfer Protocol (HTTP) used to transfer spider web pages across the Network.
Telnet
Talent is remote access protocol allows you lot to access other computers through the command line. Telnet does non usage encryption.
FTP
File Transfer Protocol (FTP) used to transfer large file through the Network. It does non admit similar UDP.
TFTP
Trivial File Transfer Protocol (TFTP) allows you lot to transfer minor file through the Network. It uses admit similar TCP.
SNMP
Simple Network Management Protocol (SNMP) allows you lot to command in addition to contend Network device.
DNS
Domain Name System (DNS) used to transfer IP address to a human-readable format.
SMTP
Simple Mail Transfer Protocol (SMTP) allows you lot to portion electronic mail betwixt emails server.

Transport Layer
The carry layer provides communication session Management betwixt host system. It defines a marking of services in addition to condition of connectedness used when transporting data.
TCP
The Transmission Control Protocol (TCP) is 1 of the primary protocols of the Internet protocol suite.[2] TCP provides connections betwixt clients in addition to servers. It uses acknowledgment during communication. If an acknowledgment is non received, TCP retransmits the data.[4] UDP
User Datagram Protocol (UDP) uses a unproblematic connectionless communication model alongside a minimum of protocol mechanism.[2] It does non usage acknowledgment. UDP is unreliable every bit compared to TCP.7 RTP
Real-Time Protocol, this Protocol is used inwards Real-time communication similar vocalisation over IP etc.

Internet Layer
This layer is responsible for creating packets of information in addition to hence adding headers to the packets. The header contains root in addition to goal information. Internet layer uses this information to frontwards the packets betwixt host across the Network. The protocol uses yesteryear this layer is
IP
Internet Protocol (IP) is a unique address that is assigned to host. IP has the chore of delivering packets from the root host to the goal host alone based on the IP addresses inwards the package headers.[2]

ICMP
Internet Control Message Protocol is used to transfer command packets across the Network. This protocol is too used yesteryear Ping in addition to Trace Route Tool.
ARP
Address Resolution Protocol is used yesteryear IP Protocol to accept a logical or IP Address in addition to detect out what is the physical or Mac Address.
RARP
Reversed Address Resolution Protocol is used when nosotros cause got physical Address only nosotros don't know IP Address.
Network Interface Layer
Sometimes called Network Access Layer. This layer specifies how information is physically sent through a network. It too explained how bits are electrically signaled yesteryear hardware. It allows hardware device to interface alongside network Medium. e.g Coaxial Cable, Optical cable, in addition to Twisted Pair Cable.
