Q2. Signal flow of AV system.
Ans. 
Signal flow of AV system refers to the path that audio and video signals take from input sources to output devices.
• Input sources such as microphones, cameras, or media players send signals to a mixer or switcher.

• The mixer or switcher processes the signals and sends them to amplifiers or processors.

• Amplifiers or processors then send the signals to output devices like speakers or displays.

• The final output is the audio an

Q1. Layers of OSI and explain in detail on packet level.
Ans. 
The OSI model consists of 7 layers that define the functions of a network. Each layer has specific responsibilities in handling data packets.
• Physical Layer: Deals with physical connections and transmission of raw data bits.

• Data Link Layer: Manages data frames and error detection/correction.

• Network Layer: Handles routing and logical addressing.

• Transport Layer: Ensures reliable data transfer between devices.

• Session Layer...read more

Q2. Explain OSPF on packet level.
Ans. 
OSPF is a routing protocol that uses link-state algorithm to determine the best path for routing packets.
• OSPF routers exchange link-state advertisements (LSAs) to build a topological database of the network.

• Each router calculates the shortest path tree to all destinations using Dijkstra's algorithm.

• OSPF uses cost metrics to determine the best path, with lower costs indicating faster links.

• LSAs are flooded throughout th...read more

Q3. Explain RIP, EIGRP, STP, RSTP, MSTP, LAG.
Ans. 
RIP, EIGRP, STP, RSTP, MSTP, LAG are networking protocols and technologies used in network engineering.
• RIP (Routing Information Protocol) is a distance-vector routing protocol.

• EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol.

• STP (Spanning Tree Protocol) prevents loops in Ethernet networks.

• RSTP (Rapid Spanning Tree Protocol) is an updated version of STP for faster convergence.

Q1. What is the difference between ipv4 and ipv6
Ans. 
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses, allowing for more unique addresses in IPv6.
• IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses

• IPv IPv4 supports 4.3 billion unique addresses while IPv6 supports 340 undecillion unique addresses

• IPv4 uses decimal notation for addresses (e.g. 192.168.1.1) while IPv6 uses hexadecimal notation (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334)

• IPv6 has built-...read more

Q2. What is osi model and explain it
Ans. 
The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and comm...read more

Q3. How does data flow trough osi model
Ans. 
Data flows through OSI model in a structured manner through different layers.
• Data is encapsulated into frames at the Application layer

• Frames are then segmented into packets at the Transport layer

• Packets are further divided into segments at the Network layer

• Segments are converted into bits at the Data Link layer

• Bits are transmitted physically through the network at the Physical layer
