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 delivery. This includes the packet itself, plus a header containing the physical addresses (MAC addresses) of the sender and receiver devices.

Addressing: Uses physical addresses (MAC addresses) of network devices for local delivery within a specific network segment (e.g., your home network).

Size: Fixed size depending on the network technology (e.g., Ethernet frames are typically 1500 bytes).

Travels within a network segment: Frames are used to deliver data within a limited area like a local network and don't handle routing across different networks.

Speed test:

Checks how fast you can get water from the outside faucet (internet) into your house (device). This reflects how fast you download and upload things.

Iperf: 

Tests how fast water can move through the pipes inside your house (LAN network) between, say, your kitchen sink (one device) and the washing machine (another device).

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. ...
