   • What exactly is the info_Hash in a torrent file

     Top Answer

     Answered Nov 30, 2018 · 72 votes

     So I finally figured it out.

     The “infohash” is the SHA1 Hash over the part of a torrent file that includes:

     • ITEM: length(size) and path (path with filename)
     • Name: The name to search for
     • Piece length: The length(size) of a single piece
     • Pieces: SHA1 Hash of EVERY piece of this torrent
     • Private: flag for restricted access

     To show this a little more I took a random torrent file and used the “BEncode Editor” from Ultima to make it more clearly to me.

     As you can see the the red box marked the information part of the torrent file. The torrent file includes not the Hash of the items, but the hashes of every piece.

     • For item1 with: 1069496548
     • and item2 with: 223
     • It is together: 1069496771
     • With a piece size of: 524288
     • There are 2040 pieces. (1069496771/524288=2039.9032 approximately)
     • The pieces section includes 40800 byte of data what are 81600 + 2 chars in the file.
     • the +2 because 0x marks that this is hexadecimal.
     • A SHA1 hash has 40 0x chars or 20 Byte of data what are 2040 SHA1 hashes.

     I am sorry that this information is about a torrent that leads to a illegal movie, but i wanted to use a torrent that realy exists.

   • What is ?v=something mean in a JavaScript file name?

     Top Answer

     Answered Dec 16, 2020 · 4 votes

     The Purpose

     It is for client-side caching.

     If you have a JS file script.js, the users browser will cache it. When you change script.js, the browser will still have the old cached version.

     So, you add a ?v=... to it so when you make changes, the browser will load the new one.

     Since it is in the HTML file, it is the server that sets the ?v=...

     To do this yourself, simply add the ?v=...

     <script src="javascript.js?v=1.0.1" type="text/javascipt"></script>-

     Example

     Say you make a script for your site and name it "script.js".

     In your code you put:

     <script src="script.js?v=1" type="text/javascipt"></script>-

     Now when you change "script.js", you change your code as follows:

     <script src="script.js?v=2" type="text/javascipt"></script>-

     Now your visitor's browsers will get the new "version" of your script file.

     Also

     You could use ?foo=... or really any other string.

   • What is Broadcasting in Computer Network?

     In computer network, there are various ways in which we can transmit data from one node to another node, one node to multiple node, and many node to many nodes. For each type of transmission, there’s a term associated with it.  Let’s see their examples in brief :

     • For node to node: ‘Unicast’ also known as POINT-TO-POINT communication. Example: cell phone conversation.
     • When multiple POINT-TO-POINT communications are made its called – ‘Multicast‘. The message is received by only those hosts who choose to be a part of a multicast group.  Example: Video conferencing, sending a message targeting number of people at at a time.
     • One Node to ALL Nodes – Broadcasting. Today we’ll discuss broadcasting in depth.

     What is Broadcasting?Broadcasting in computer networks is a type of communication mechanism that allows the message to be received by all the nodes of a network. The term broadcast in general refers to the transmission of signals from radio or televisions.

     Every broadcasted signal is stopped at layer-3 network layer of OSI or to be more practical – at the router. A more technical example of Broadcasting would be: The Address-Resolution-Protocol request (ARP-Request) whenever a host needs to resolve an IP address to its corresponding MAC address it will broadcast a signal asking “Who this IP address belongs to?” and this broadcasted signal is received by every single node in a network domain and then an appropriate node will respond accordingly.

     Let’s take example of a broadcast message with an IPv4 address, see the below two diagram of two...

     • The sender of the message to be broadcasted will initiate the process by setting the destination address as the broadcast address of the network.
     • The message is encapsulated into the network frame with the destination MAC Address set to the broadcast MAC Address.
     • The message is then finally broadcasted, and is received by all the devices of the intended network and the devices that receive this message check if the broadcast matches with their own IP Address.
     • If its a match, then device proceeds with the message further else it discards it.
     • There is a total of 256 values for each octet (0-255). So we’ll subtract 248 from 256. 256-248 = 8.
     • 8 here is called the multiplier. Now we have to determine how many multiples of 8 we need to come up with in order to obtain a value just GREATER than – 33 (4th octet in the given IP – 192.168.3.33).
     • Checking multipliers of 8 (keep adding 8 until you get a number greater than 33) :-
     • 8 + 8 = 16      (16 < 33)
     • 16 + 8 = 24     (24 < 33)
     • 24 + 8 = 32     (32 < 33)   
     • 32 + 8 = 40     (40 > 33)

   • What is Delay Distortion in Computer Network?

     Delay distortion is basically a process where the frequency and velocity of signal wave can transmit only at a certain range of bandwidth in a particular medium. This process leads to delay distortion as the velocity and frequency will not be able to travel at the same amplitude as before which will eventually lead to a delay in the arrival of the wave. This delay in the time interval is the main property shown by the refractive index of that medium because the frequency and velocity get differently impacted by the refractive index of the medium.

     The data network signals get distorted over that medium due to varying frequency and velocity. Hackers may get access to this distorted data as it is a high vulnerability to data leaks. Any single data packet in the distorted network data path may spill all the data out and it may result in destabilization of the entire transmission line of the data packets over the network.

     However, we can solve the problem of data delay distortion using a telephone line that equalizes the speed as well as the frequency of the...

   • What is Dynamic Routing in Computer Network?

     Routing is a procedure of making decisions in which the router (which is a hardware device used in networking to receive and send data in the form of packets on a network) selects the best path to make data transfer from source to destination. A router exists in the network layer in the OSI as well as TCP/IP model. Some functions of a router are:

     • Building an optimal path on a network to reach its destination (in which static and dynamic routing take place).
     • Taking routing decisions.
     • Balancing load.

     Types of Routing:

     • Static routing
     • Default routing
     • Dynamic routing

     Static and Default routing has some drawbacks, due to which Dynamic Routing was introduced.

     Drawbacks of Static Routing:

     It is a burdensome task to sum up or add-on each route manually to the routing map in a large...

   How Torrent files are encoded?

   • Torrent files are encoded with a custom encoding called Bencoding. It supports data types such as Strings, Integers, List, and Dictionaries (which can only hold string keys). Strings are encoded as : . Hence, a string arpit will be encoded as 5:arpit. Integers are encoded as i e. Hence, an integer 10 will be encoded as i10e.

   How does BitTorrent work?

   • The torrent file acts as the key to initiating downloading of the actual content. Someone interested in receiving the shared file or folder first obtains the corresponding torrent file, either by directly downloading it or by using a magnet link. The user then opens that file in a BitTorrent client, which automates the rest of the process.
