Network Architecture

 

NETWORK ARCHITECTURE

NETWORK ARCHITECTURE MEANS THE NETWORK LAYOUT THAT TELLS US HOW COMPUTERS ARE ARRANGED AND HOW THE TASKS OR COMPUTERS ARE LOCATED.

TYPES OF NETWORK ARCHITECTURE

1.PEER TO PEER ARCHITECTURE

A PEER-TO-PEER NETWORK, ALSO KNOWN AS A POINT-TO-POINT NETWORK, IN WHICH ALL COMPUTERS ARE DIRECTLY CONNECTED TO EACH OTHER AND EQUAL PRIVILEGES AND ESPONSIBILITIES FOR SHARING DATA.

THERE IS  NO SERVERS IN IT.

ADDVENTAGES OF PEER TO PEER ARCHITETURE

1. IT IS A CHEAP NETWORK BECAUSE IT HAS NO SERVERS.

2. IF ONE COMPUTER STOPS WORKING, IT WILL NOT AFFECT OTHER COMPUTERS.

3. IT IS ALSO EASY TO SET UP AND MAINTAIN.SECURITY ISSUE.

4. WE CANNOT BACKUP THE DATA BECAUSE THERE IS NO SERVER.

2.CLIENT-SERVER-MODEL ARCHITECTURE

CLIENT-SERVER ARCHITECTURE ALSO KNOWN AS REQUEST-RESPONSE ARCHITECTURE.

IN THIS ARCHITECTURE, THE CLIENT MAKES A REQUEST TO THE SERVER AND THE SERVER WILL RETURN THE RESPONSE.

THE CLIENT-SERVER ARCHITECTURE REFERS TO A SYSTEM THAT HOSTS, DELIVERS, AND MANAGES MOST OF THE RESOURCES AND SERVICES THAT THE CLIENT REQUEST.

ADDVANTAGES OF CLIENT-SERVER-MODEL ARCHITECTURE

1.IT HAS A CENTRALIZED SYSTEM FROM ALLOWS DATA TO BE BACKED UP EASILY.

2.SECURITY IS BETTER IN THIS NETWORK.

3. ENTIRE SYSTEM IS MAINTAINED BY A SERVER .

4.THIS ALSO INCREASES THE SPEED OF RESOURCE  AND SHARING.

CSST COURSE 1.0

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. ...
