Datagram, fragment, packet segment, frame - what's the difference?

Question

JavaScript

I can not understand how a datagram differs from a fragment, packet, segment and frame? What is written on the Internet about this is often conflicting information or very confusing.

Answer 1

Bro, your problem is something else - an error in passing css method parameters. In the right way:

setTimeout(() => test.css("display", "none"), 2000);

Answer 2

It works. Just test == undefined

Answer 3

datagram - a block of information
fragment - part of a whole (for example, a fragment of a legendary sword for killing trolls)
a package - data collected in one place for sending (a bundle with a variety of food that a daughter carries to her father in the field)
segment - a selective object of interest to us. most often networks (a square of the Vietnamese coast that will be bombed)
frame - a data fragment of the OSI model link layer protocol

Answer 4

There is an OSI model. There are many levels. Each transmits data in quanta. At the network level, a quantum is called a packet, at the channel level - a frame. That's the whole difference.

Answer 5

These are all conventions for different parts (or the whole) of network protocol packets. At different protocol levels (according to the OSI model), the same (by meaning) parts can be called differently. Somewhere - a frame, somewhere - a packet, somewhere - a frame. But this is all conditional. Details can be gleaned in the book on the Cisco ICND1 course, they make a special emphasis on this there.
