It follows a decentralized architecture, and there is no master architecture. Random access allows stations to transmit without permission, emphasizing equal fairness.* 01:03:38 Random *access protocols don't dictate who transmits next; it's a random decision. The system doesn't reveal successful or failed transmissions, and the next transmitting station is unpredictable.* 01:05:41 Understanding *random access involves creating diagrams for different scenarios, a crucial skill for exams. The process involves starting transmission, checking the medium for ongoing transmissions, and making decisions based on the presence of other transmissions.* 01:14:47 When *discussing channel bandwidth, the speaker mentions a 200-byte frame with a bandwidth of 200kb. The unitary method is applied to calculate transmission time.* 01:28:11 Probability *mechanism: Stations set a random number; if it's less than a predefined probability, they transmit. This minimizes collisions.* 01:32:38 Voltage *Level Identification for Collision Detection: In case of collision, voltage levels vary. Use identification methods like persistence and resistance. Utilize components like persistence, resistance, and parasitism for detection. Successful transmission is achieved without acknowledgment if no collision is detected during transmission.* 01:43:50 If *corruption or errors are detected in a frame at the receiver, the frame is silently discarded, and the negative acknowledgment is not explicitly sent.* 01:47:18 The *concept of queuing delay is introduced, highlighting the potential waiting time at switching devices like routers and switches.* 01:48:53 Factors *like packet size, transmission time, propagation time, and acknowledgment time are crucial in calculating the efficiency of data transmission.* 01:50:54 The *formula considers the transmission time of data, propagation time, acknowledgment time, and back propagation time, treating them as essentially the same.* 01:51:22 The *total time formula, considering all factors, provides a comprehensive approach to calculating the time required for transmitting data in a network.* 01:54:46 Demonstrating *the sliding window mechanism in Go Back N and its role in efficient packet transmission.* 02:16:32 Discussing *the trade-off between cost and error detection capabilities, the video highlights the minimum Hamming distance as a crucial property for effective error detection in different code words.* 02:21:14 Bit *data word contains original data, and redundancy is added using Reed-Muller code with parameters k = 2, power r - r-1. This forms a game to determine overall cost.* 02:28:16 Explains *the process of checksum verification, emphasizing the importance of comparing the calculated sum at the receiver's end.* 02:32:31 Introduction *to Cyclic Redundancy Check (CRC) in error detection and its basic concept.* 02:32:59 Circular *right shift is demonstrated by shifting each bit one position to the right. This creates a cyclic code, representing logical operations like checksums.* 02:33:25 Checksums, *used in CRC (Cyclic Redundancy Check), involve sending a sum with data to verify integrity. Division cannot be applied directly, but a reminder mechanism is employed.* 02:36:36 Perfectly *divisible numbers and remainders play a crucial role in error detection in network communication.* 02:47:54 When *sending data, there is a logical restriction to not send more than 1500 bytes at once. The data link layer includes a trailer, like CRC, for cyclic redundancy check.* 02:52:00 Token *Passing mechanism in Token Ring was deterministic, suitable for real-time applications, ensuring collision-free communication.* 02:59:09 IP *version 4 (IPv4) is the most popular variant of the Internet Protocol, and its detailed study is crucial in networking courses.* 03:00:46 Various *fields in the header address different aspects like type of connection, general tariff, and best-effort delivery.* 03:09:40 The *maximum number in a 16-bit field is 65535, representing the maximum data a packet can carry. Payload length calculation doesn't involve storing a direct number.* 03:24:59 Understanding *the importance of the additional 20 bits, knowing the address of intermediate routers, and using 32-bit addresses for independent routers allow for effective routing.* 03:33:14 Additional *protocols like ARP and ICMP are necessary for resolving local addresses and providing information during system boot.* 03:36:11 Reverse *Address Resolution Protocol (RARP) is introduced, addressing how a system discovers its IP when connected to a network for the first time.* 03:41:13 ICMP *is also useful in query reporting, allowing routers to communicate errors, diagnose issues, and enable network managers and users to pinpoint and address network problems effectively.* 03:43:46 Router *communication through ICMP and timestamping can be utilized to measure the distance and processing delay of routers in a network.* 03:46:19 Reference *to the transition from IPv4 to IPv6, highlighting the vast number of IPv6 addresses available.* 03:50:20 Using *a 32-bit address, divided into prefix (network ID) and suffix (host ID) to identify systems within networks.* 03:51:02 Drawing *an analogy to telephone numbers, explaining the concept of network and host identification within an address.* 03:54:38 Class *C networks explained, with a focus on smaller villages with fewer IP addresses.* 03:58:34 Hosts *in Class A have 24 bits, resulting in 2^24 combinations minus 2 reserved IDs.* 03:58:49 Host *IDs have an All-Zero ID reserved for network and an All-One ID reserved for broadcasting.* 04:06:39 Understanding *the concept of limited broadcast and direct broadcast is crucial in networking. Use the total network ID in the destination to avoid complications within the local network.* 04:18:42 Discussing *CIDR notation in detail, calculating the number of addresses, and understanding the network length.* 04:21:14 Highlighting *the application of the "NOT of Mask" method for calculating the number of addresses, emphasizing the direct calculation approach.* 04:27:09 Emphasizes *the need for periodic updates in dynamic routing, drawing parallels with changing train schedules and the impact of events like the railway budget.* 04:27:23 Discusses *the dynamic nature of industries like airlines and stock exchanges, where rates and schedules change frequently.* 04:30:42 Explains *intra-domain and inter-domain concepts, emphasizing the need for decentralized, autonomous systems in managing the internet.* 04:35:03 Routing *algorithms may consider different costs, such as time-based or distance-based, depending on the specific requirements.* Made with HARPA AI

Thankyou very much sir, my CN mid sem is day after tomorrow and I am studying through this video. I always considered subjects like Computer network and web technology to be very hard and filled with rote learning. The truth is that our curriculum is purely theoretical and to be honest the theory part of these subjects is really hard to learn. The language also seems difficult especially if we try to read from books. I think that this is what makes these subjects hard and boring for me. But I really like your style of teaching very much! Thanks to you, I am actually having fun learning this subject, which frankly I never thought I would. Also I really like your way of mixing humor between studies, it really makes the things much more enjoyable and less stressful. Your railway line example at 1:21:15 to explain CSMA, really made me laugh a lot! Thankyou very much for your efforts to make this subject easier for college students like me. 😊

47:12 Short-range *communication is efficient using radio waves due to their quick dissipation in the atmosphere.*
48:34 Understanding *the spectrum for communication, ranging from visible light to infrared, microwaves, and radio waves.*
54:22 Traditional *telephone services used analog ISDN for transmission, while the internet was used for data communication.*
55:00 The *decline in old technologies like ISDN is attributed to the rise of broadband and the latest technologies.*
55:28 Two *types of data link layer are introduced: the lower half, which includes the MAC address and media access control, and the upper half, which involves logical link control (LLC).*
57:57 Defining *Propagation Delay in general terms, representing it as Tp (time per distance upon speed), simplifying the understanding of this fundamental concept.*
01:00:17 Introduces *the concept of cold transmission time and explains that the first drop of water may take 5 minutes to reach when the system starts.*
01:00:57 Expands *on the example of a game starting at **12:00** and the time it takes for the first and last drops of water to reach the destination, relating it to transmission propagation delay.*
01:03:11 In *random access, all stations are independent; no station is superior or assigned to control others. It follows a decentralized architecture, and there is no master architecture. Random access allows stations to transmit without permission, emphasizing equal fairness.*
01:03:38 Random *access protocols don't dictate who transmits next; it's a random decision. The system doesn't reveal successful or failed transmissions, and the next transmitting station is unpredictable.*
01:05:41 Understanding *random access involves creating diagrams for different scenarios, a crucial skill for exams. The process involves starting transmission, checking the medium for ongoing transmissions, and making decisions based on the presence of other transmissions.*
01:14:47 When *discussing channel bandwidth, the speaker mentions a 200-byte frame with a bandwidth of 200kb. The unitary method is applied to calculate transmission time.*
01:28:11 Probability *mechanism: Stations set a random number; if it's less than a predefined probability, they transmit. This minimizes collisions.*
01:32:38 Voltage *Level Identification for Collision Detection: In case of collision, voltage levels vary. Use identification methods like persistence and resistance. Utilize components like persistence, resistance, and parasitism for detection. Successful transmission is achieved without acknowledgment if no collision is detected during transmission.*
01:43:50 If *corruption or errors are detected in a frame at the receiver, the frame is silently discarded, and the negative acknowledgment is not explicitly sent.*
01:47:18 The *concept of queuing delay is introduced, highlighting the potential waiting time at switching devices like routers and switches.*
01:48:53 Factors *like packet size, transmission time, propagation time, and acknowledgment time are crucial in calculating the efficiency of data transmission.*
01:50:54 The *formula considers the transmission time of data, propagation time, acknowledgment time, and back propagation time, treating them as essentially the same.*
01:51:22 The *total time formula, considering all factors, provides a comprehensive approach to calculating the time required for transmitting data in a network.*
01:54:46 Demonstrating *the sliding window mechanism in Go Back N and its role in efficient packet transmission.*
02:16:32 Discussing *the trade-off between cost and error detection capabilities, the video highlights the minimum Hamming distance as a crucial property for effective error detection in different code words.*
02:21:14 Bit *data word contains original data, and redundancy is added using Reed-Muller code with parameters k = 2, power r - r-1. This forms a game to determine overall cost.*
02:28:16 Explains *the process of checksum verification, emphasizing the importance of comparing the calculated sum at the receiver's end.*
02:32:31 Introduction *to Cyclic Redundancy Check (CRC) in error detection and its basic concept.*
02:32:59 Circular *right shift is demonstrated by shifting each bit one position to the right. This creates a cyclic code, representing logical operations like checksums.*
02:33:25 Checksums, *used in CRC (Cyclic Redundancy Check), involve sending a sum with data to verify integrity. Division cannot be applied directly, but a reminder mechanism is employed.*
02:36:36 Perfectly *divisible numbers and remainders play a crucial role in error detection in network communication.*
02:47:54 When *sending data, there is a logical restriction to not send more than 1500 bytes at once. The data link layer includes a trailer, like CRC, for cyclic redundancy check.*
02:52:00 Token *Passing mechanism in Token Ring was deterministic, suitable for real-time applications, ensuring collision-free communication.*
02:59:09 IP *version 4 (IPv4) is the most popular variant of the Internet Protocol, and its detailed study is crucial in networking courses.*
03:00:46 Various *fields in the header address different aspects like type of connection, general tariff, and best-effort delivery.*
03:09:40 The *maximum number in a 16-bit field is 65535, representing the maximum data a packet can carry. Payload length calculation doesn't involve storing a direct number.*
03:24:59 Understanding *the importance of the additional 20 bits, knowing the address of intermediate routers, and using 32-bit addresses for independent routers allow for effective routing.*
03:33:14 Additional *protocols like ARP and ICMP are necessary for resolving local addresses and providing information during system boot.*
03:36:11 Reverse *Address Resolution Protocol (RARP) is introduced, addressing how a system discovers its IP when connected to a network for the first time.*
03:41:13 ICMP *is also useful in query reporting, allowing routers to communicate errors, diagnose issues, and enable network managers and users to pinpoint and address network problems effectively.*
03:43:46 Router *communication through ICMP and timestamping can be utilized to measure the distance and processing delay of routers in a network.*
03:46:19 Reference *to the transition from IPv4 to IPv6, highlighting the vast number of IPv6 addresses available.*
03:50:20 Using *a 32-bit address, divided into prefix (network ID) and suffix (host ID) to identify systems within networks.*
03:51:02 Drawing *an analogy to telephone numbers, explaining the concept of network and host identification within an address.*
03:54:38 Class *C networks explained, with a focus on smaller villages with fewer IP addresses.*
03:58:34 Hosts *in Class A have 24 bits, resulting in 2^24 combinations minus 2 reserved IDs.*
03:58:49 Host *IDs have an All-Zero ID reserved for network and an All-One ID reserved for broadcasting.*
04:06:39 Understanding *the concept of limited broadcast and direct broadcast is crucial in networking. Use the total network ID in the destination to avoid complications within the local network.*
04:18:42 Discussing *CIDR notation in detail, calculating the number of addresses, and understanding the network length.*
04:21:14 Highlighting *the application of the "NOT of Mask" method for calculating the number of addresses, emphasizing the direct calculation approach.*
04:27:09 Emphasizes *the need for periodic updates in dynamic routing, drawing parallels with changing train schedules and the impact of events like the railway budget.*
04:27:23 Discusses *the dynamic nature of industries like airlines and stock exchanges, where rates and schedules change frequently.*
04:30:42 Explains *intra-domain and inter-domain concepts, emphasizing the need for decentralized, autonomous systems in managing the internet.*
04:35:03 Routing *algorithms may consider different costs, such as time-based or distance-based, depending on the specific requirements.*

Thankyou very much sir, my CN mid sem is day after tomorrow and I am studying through this video.
I always considered subjects like Computer network and web technology to be very hard and filled with rote learning. The truth is that our curriculum is purely theoretical and to be honest the theory part of these subjects is really hard to learn. The language also seems difficult especially if we try to read from books.
I think that this is what makes these subjects hard and boring for me.
But I really like your style of teaching very much!
Thanks to you, I am actually having fun learning this subject, which frankly I never thought I would.
Also I really like your way of mixing humor between studies, it really makes the things much more enjoyable and less stressful.
Your railway line example at 1:21:15 to explain CSMA, really made me laugh a lot!
Thankyou very much for your efforts to make this subject easier for college students like me. 😊
Glad to know you liked the content @Naman, thanks for following, wish you all the best for your exam, do well. Stay connected for more content & do share the video with your friends if you find it to be helpful.
