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 .

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. 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. ...

LSA TYPES

In OSPF, different types of routers create various types of LSAs (Link-State Advertisements) depending on their roles in the network. Here’s a breakdown of the routers and the LSAs they generate:   1. All Routers (including internal routers):    - Type 1: Router LSA       - Every router in an OSPF area generates a Type 1 LSA, which describes its own interfaces and links within the same area.   2. Designated Router (DR):    - Type 2: Network LSA       - The DR on multi-access networks (like Ethernet) generates this LSA to describe all the routers attached to the shared network.   3. Area Border Router (ABR):    - Type 3: Summary LSA       - ABRs generate Type 3 LSAs to advertise networks from one OSPF area to another (inter-area communication).    - Type 4: ASBR Summary LSA       - ABRs also generate Type 4 LSAs to describe the path to...
