Switch

 

WHAT IS SWITCH

1. SWITCH IS A NETWORK DEVICE THAT CONNECT MULTIPAL COMPUTERS TOGETHER IN THE NETWORK.

2. SWITCH COMMUNICATION BASED ON MAC-ADDRESS.

3. SWITCH CAN EASILY INDETIFIE THAT WHICH DEVICE IS CONNECTED WHICH WITH PORT BY USING MAC-ADDRESS THAT WHY IT DELIVERED MESSAGE ON PARTICULAR DESTINATION MACHINE.

2 TYPES OF SWITCH.

 1. UNMENADABLE SWITCH 

NO CONFIGRATION AND VERIFIVATION CAN BE DONE.  
 
THERE IS NO CONSOL PORT. PLUG AND PLAY IS USED AND CONNECT.

 2. MENAGEABLE SWITCH: 

WE CAN CONFIGRATION AND VERIFICATION THROUGH SOME LAN PROTOCOL. IT HAS A CONSOLE PORT.  LAN PROTOCOL: UTP,STP,ULAN.

ADDVANTAGES OF SWITCH

1. IT GENERALLY USED TO UNICAST THE MESSAGE.

2. IT PROVIDES MORE SECURITY THAN HUB.

3. SWITCH SUPPORT FULL DUPLEX DATA TRANSMISSION MODE.

4. IF A NODE FAILS,THERE WILL BE NO EFFECT IN THE ENTIRE NETWORK.

5. IT IS USED TO SEND DATA PACKET BASED ON MAC-ADDRESS.

DISSADVANTAGES OF SWITCH

1. IF SWITCH IS FAILED THEN ENTIRE NETWORK WILL BE FAILED.

2. IT IS MORE EXPENSIVE.

3. DIFFICULT TO SETUP.

WHEN FIRST TIME ROUTER HIS OPEN THE FIST MODE HIS APPEARS

   switch>   AND WHEN TO ENABLE MODE TO ENTER    switch> enable

SEE  TO ENABLE MODE    switch#

AND WHEN TO CONFIGURATION MODE TO ENTER  switch# config t

AND SEE THE CONFIGURATION MDE  switch(config)#

_______________________

THE PURPOSE OF ENABLE MODE IS ALL THE CONFIGURATION YOU PERFORMS A SWITCH TO SEE IT AND ANY IP PING IN ENABLE MODE
AND CHECK COMMUNICATION.

THE PURPOSE OF CONFIGURATION TERMINAL MODE ALL THE PROTOCOLS AND CONFIGURATION POERFORMED HIS MODE.

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. ...
