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...

  1.  Seeing Wi-Fi SSID on Ethernet connection is normal.  Both connect to the same network, and OS might just display the familiar Wi-Fi name. No worries, it's just a display quirk. You can rename the connection in settings if you prefer. 2.    Frequency range of single mode fiber  : Typically used in the 1260 nm to 1625 nm range.      Frequency range of   multimode mode fiber  : Typically used in the 850 nm  to 1300 nm range.    3.  How Routing Works: A device on your local network sends a data packet (like a car) with a destination IP address (like a destination city). The packet reaches your router (like the highway interchange). The router checks the destination IP address and routing table (like a map) to determine the best path to the remote network. The router forwards the packet to the appropriate network (like directing the car onto the correct highway). 4. How Switching Works: A device sends a...

  Typical range: In ideal conditions (empty space, no walls), a 2.4 GHz signal can reach around 150 feet (45 meters) indoors and 300 feet (90 meters) outdoors. Reality check:   Walls, furniture, appliances, and other obstacles can significantly reduce the range. In a typical home environment, expect a range of 30-50 meters (100-165 feet) or less. Range:   Expect a coverage of around 15 meters (50 feet) for a 5 GHz signal. This can be significantly lower in environments with obstacles or interference.

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...

  Problem: Private traces can fail, but network gadgets may not detect it. This can result in statistics getting stuck because it can't be rerouted. Reason: Traditional routing protocols rely on timers, which may be sluggish to come across disasters. Solution: BFD protocol acts like a quick heartbeat test between routers. If one router would not respond fast sufficient, the issue is detected, and site visitors can be rerouted to the backup line. Benefit: BFD allows avoid "facts forwarding black holes" by way of quickly switching to backup paths, improving community balance. __________ CONFIGURATION Configured Loopback And Assign Ip Address on Router 1 R1(config)#inter lo 0 R1(config-if-Loopback 0) #ip add 1.1.1.1 32   R1(config-if-Loopback 0) #inter g0/0 R1(config-if-GigabitEthernet 0/0)#ip add 12.0.0.1 30 Configured Loopback And Assign Ip Address on Router 2   R2(config)#inter lo 0 R2(config-if-Loopback 0)#ip add 2.2.2.2 32   R2(config-if-L...
