    Parallel & Distributed Computing
    Explain the wroking of Bit Torrent with example of
    each option:
    Once connected, a BitTorrent client downloads bits of the files in the torrent in small pieces,
    downloading all the data it can get. Once the BitTorrent client has some data, it can then
    begin to upload that data to other BitTorrent clients in the swarm. In this way, everyone
    downloading a torrent is also uploading the same torrent.

    Time Elapsed
    The number of minutes that each torrent has been running. This is information that uTorrent
    already tracks -- it's viewable under "Transfer" on the "General" tab -- so I suspect it would
    be a simple matter to implement as a sortable column. I used it frequently in Azureus for
    weeding out long-dead torrents from my list while preserving the ones in a temporary lull.

    For example
    if I've been on a torrent for two weeks and only uploaded two megabytes, I can remove it
    and make room for more effective seeding opportunities. If I've only been on it for five
    minutes, though, I stay on.

    Downloaded:
    It shows that whether the file has been downloaded or being downloading.

    Download Speed:
    ... Download speeds normally happen at faster speeds than uploads; however, that can
    depend on broadband connections or how web pages are created.

    Down Limit:
    In bit torrent u can fix the speed of downloading. You can set the speed of downloading so
    that the speed of your internet may not disturb so much.

    Status:
    Status shows the current situation of the torrent. If you re downloading a file than the update
    about that file will be shown by status.
    Up Limit:
    Torrent employs a mutual fair sharing algorithm, that ensures fairness in a torrent swarm.
    Users that upload more are usually prioritised. And if you limit upload too much your
    download speed will be affected as well. Limiting uploads depends on your usage frequency
    and bandwidth plan.

    Seeds 
    Seeds displays the number of seeds you are connected to, and the number of seeds in the
    swarm in the parentheses. The number in the swarm is collected from the tracker and other
    methods of exchanging peers, such as DHT or Peer Exchange.

    Peers
    Peers displays the number of peers you are connected to, and the number of peers in the
    swarm in the parentheses. The number in the swarm is collected from the tracker and other
    methods of exchanging peers, such as DHT or Peer Exchange.

    Share Ratio:
    Ratio is the amount of data you have downloaded for a torrent share (or all torrents on the
    site) divided by the amout of data you have uploaded. ... A ratio of more than 1 means
    you have uploaded more than the amount you downloaded, e.g. if you are seeding something
    for a long time.

    Wasted:
    Wasted means bad data has been received by your torrent client.  This data is discarded
    (wasted) because your torrent client didn’t want or need it.  Your torrent client is set up to
    automatically verify all downloaded data to ensure that only correct data is written to disk.

    Upload speed 
    Upload speed is the speed that your computer can transfer or send information to
    the Internet.
