the channel is useful, but i suggest that if it is beginning of a series of videos for a course, an simple introduction is needed, bcz i get lost for the 1st minute on the first video, i wish you'd tell me what i should already know before taking this course, so i know that it is for me or not! thanks @itechnica
The following encoding is used in data link protocol: A:01000111; B:11100011; FLAG:01111110; ESC:11100000. What will be the bit sequence for the five characters frame: A B ESC B FLAG when character count method of framing is used? How to solve this question? Please sir...
Hi, In Byte Stuffing, start and end of frame are recognized with the help of flag bytes. Each frames starts with and ends with a flag byte. Two consecutive flag bytes indicate the end of one frame and start of the next one. General Sequence of Frame is as follows: FLAG HEADER PAYLOAD TRAILER FLAG In byte stuffing, a special byte called the escape character (ESC) is stuffed before every byte in the message with the same pattern as the flag byte. If the ESC sequence is found in the message byte, then another ESC byte is stuffed before it. For E.g. (ORIGINAL CHARACTER --> AFTER STUFFING) 1). A FLAG B - -> A ESC FLAG B 2). A ESC B --> A ESC ESC B 3). A ESC FLAG B --> A ESC ESC ESC FLAG B 4). A ESC ESC B --> A ESC ESC ESC ESC B Similarly, for your question: A B ESC B FLAG --> A B ESC ESC B ESC FLAG will be followed. Thanks, Team iTechnica
Hi, In this video we have shown the working normally in the first step i.e. How frames will be created? But in second step we have shown that it may be possible that due to some transmission error any data bit may get garbled. That's why we have denoted 5 as 7 just to show error in data frame. Instead of 7 it may be anything. Thanks!!
uma devi Hi ! Its not always, it depends on the length of frame. For eg if frame contains 4 elements then header will be 5 including itself as a member of frame, if frame contains 6 elements then header will be 7 including itself. Thanks !!
Bro U R live savior !!!!!💜💖😥😥💜💖💖
It's amazing. The simplest method of teaching. Thanks for these video...
Nice 👍
Nice video
A Big thanks from kerala 👏👍👌

Nice explanation
Please include video on ip addressing and sub netting
Hi !! We will upload remaining lectures of computer networks very soon.
Thanks !!!
@@itechnica Please sir do it soon. It will be very beneficial then for us. specially network layer
Actual video starts from 4:26
network layer ka video kyu nhi nanaye hai sir
why the 5 becomes 7 in the second step ?

Sir why add the header in 5

Thank you sir
oke?
