TCP (TRANSMISSION CONTROLL PROTOCOL)

TCP STANDS FOR TRANSMISSION CONTROL PROTOCOL WHILE IP STANDS FOR INTERNET PROTOCOL. 

TCP IS USED TO TRANSFER  DATA INTO SMALL PACKETS AND SEND IT TO THE DESTINATION THROUGH THE NETWORK.

WHILE IP IS USED FOR ADDRESSING THROUGH WHICH DATA REACH THE FIND DESTINATION.

UDP (USER DATAGROUND PROTOCOL)

UDP STANDS FOR USER DATA GROUND PROTOCOL.

IT IS AN UNRERIABLE  AND CONNECTIONLESS PROTOCOL.

SO IN ORDER TO  SEND DATA FROM ONE MACHINE TO ANOTHER MACHINE TO ANOTHER MACHINE WE DID NOT ESTABLISH ANY CONNECTION AS COMPARED TO TCP IP PROTOCOL.

IT IS USED FOR TRANSFER THE DATA IN A SHORT DISTANCE.

FTP 

FTP STANDS FOR FILE TRANSFER PROTOCOL IS USED TO TRANSFER THE FILE FROM SERVER TO CLIENT MACHINE AND VICE VERSA.

FILE SERVER IS A COMPUTER RESPONSIBLE FOR THE STORAGE AND MANAGEMENT OF DATA FILES SO THAT OTHER COMPUTER ON THE SAME NETWORK CAN ACCESS THIS FILE.

IT IS USES THE TCP IP PROTOCOL TO ENABLE DATA TRANSFER.

FTP PORT NO IS 21.

DHCP

A DHCP SERVER IS A NETWORK SERVER THAT AUTOMATICALLY PROVIDES AND ASSIGNS IP ADDRESSES, DEFAULT GATEWAYS AND OTHER NETWORK PARAMETERS TO CLIENT DEVICES.

IT RELIES ON THE STANDARD PROTOCOL KNOWN AS DYNAMIC HOST CONFIGURATION PROTOCOL OR DHCP TO RESPOND TO BROADCAST QUERIES BY CLIENTS.

TFTP 

TRIVIAL FILE TRANSFER PROTOCOL (TFTP) IS A SIMPLE PROTOCOL THAT PROVIDES BASIC FILE TRANSFER FUNCTION WITH NO USER AUTHENTICATION.

TFTP IS BEST WHEN TRANSFERRING DATA LOCALLY WITHIN A DATA CENTER WHERE SECURITY AND NETWORK STABILITY IS NOT AN ISSUE.

ONE OF THE MAIN ADVANTAGES OF USING TFTP BOOT IS ITS SIMPLICITY AND SPEED. TFTP IS A VERY SIMPLE PROTOCOL THAT DOES NOT REQUIRE ANY AUTHENTICATION, ENCRYPTION, OR ERROR CORRECTION.

TFTP PORT NO IS 69.

SMTP

THE SIMPLE MAIL TRANSFER PROTOCOL IS AN INTERNET STANDARD COMMUNICATION PROTOCOL FOR ELECTRONIC MAIL TRANSMISSION.

MAIL SERVERS AND OTHER MESSAGE TRANSFER AGENTS USE SMTP TO SEND AND RECEIVE MAIL MESSAGES.

ORIGINALLY, THE SIMPLE MAIL TRANSFER PROTOCOL (SMTP) USED PORT 25. TODAY, SMTP SHOULD INSTEAD USE PORT 587 — THIS IS THE PORT FOR ENCRYPTED EMAIL TRANSMISSIONS USING SMTP SECURE (SMTPS).

PORT 465 IS ALSO USED SOMETIMES FOR SMTPS.

However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...
