What is a FTP

 

FTP (File Transfer Protocol) ka kaam hai files ko ek machine se dusre machine par transfer karna. Yeh primarily upload aur download files ke liye use hota hai, aur remote servers se files access karne ke liye bhi use hota hai.


FTP ka kaam kaise hota hai:


1. *Client-Server Model*: FTP ek Client-Server Model par kaam karta hai. Aapka FTP client (jaise FileZilla ya command prompt) remote FTP server (jahan files store hote hain) se connect hota hai.

2. *Connection Establishment*: Jab aap FTP client ko open karte hain, toh aapko server ke IP address, username, aur password enter karna hota hai. Yeh certification process hai.

3. *File Operation*: Connection establish karne ke baad, aap FTP client se files upload aur download kar sakte hain. Aap directories search kar sakte hain, aur files move aur delete kar sakte hain.

4. *Data Transfer*: FTP se aap binary files (images, videos) aur text-based files (documents, scripts) transfer kar sakte hain.


*Port*: FTP ke liye do ports use hote hain:


- Port 21: Default control port hai, jahan commands exchange hote hain.

- Port 20: Data transfer ke liye use hota hai.


*Safety Information*: FTP ek unencrypted protocol hai, jiske matlab data transfers plain text mein hote hain (aur password bhi). Isliye, SFTP (Secure FTP) ya FTPS use karna zyada secure hai, kyunki yeh encrypted communication provide karte hain.

 

Example:

Aap apne FTP client (e.g., FileZilla) mein server address (ftp.example.com), username, aur password enter karte hain.

Aap server se connect ho jate hain.

Ab aap files ko local machine se server par upload kar sakte hain, ya server se apni required files download kar sakte hain.

File Size :

FTP ma ap 2gb taak ki file ko upload/download kr skty h.

TFTP ma ap 32mb ki file ko upload/download kr skty h .

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Internet Protocol (IP) Address

  IP ADDRESS IT IS A UNIQUE ADDRESS THAT WE CAN ASSIGN TO DEVICE .SO THAT DEVICECAN COMMUNICATE WITH EACH OTHER. WE CANNAOT ASSIGN SAME IP ADDRESS IN ANY TWO DEVICES IN OUR NETWORK. IF WE WILL DO THIS THEN IT WILL BE  CAUSE A CONFLICT ERROR. TWO VERSION OF IP ADDRESS: 1: IPV4 ; 2: IPV6 ; IPV4 32 BITS AND IPV6 128 BITS. AN IP ADDRESS, OR INTERNET PROTOCOL ADDRESS, IS A SERIES OF NUMBERS THAT IDENTIFIES ANY DEVICE ON A NETWORK.  COMPUTERS USE IP ADDRESSES TO COMMUNICATE WITH EACH OTHER BOTH OVER THE INTERNET AS WELL AS ON OTHER NETWORKS. TO FIND THE IP ADDRESS CLASS WE NEED TO LOOK AT THE FIRST DIGIT OF THE IP ADDRESS. AND BY LOOKING AT THE FIRST DIGIT, WE CAN GUESS THE SUBNET MASK TO WHICH CLASS IT BELONGS. CLASS A IP ADDRESS SUBNET MASK 255.0.0.0 CLASS B IP ADDRESS SUBNET MASK  255.255.0.0  CLASS C IP ADDRESS SUBNET MASK 255.255.255.0 IANA TABLE IP RANGES                 IANA   ( Internet Assigned Numbers Au...
