    Schematic for a Networking Hub and Switch

    Gunnar, i agree with you "to work hard to "delearn" what you think that you know", there are lot of things one needs to delearn, because if we do something long enough one's alertness/inquisitiveness subsides and the biggest impediment is an illusion that we understand.( until it comes back to...

    Schematic for a Networking Hub and Switch

    I am trying to understand the full and half duplex logic. So i am trying to understand the consequence of each logic at the Physical layer. Basically i am trying to understand PHY layer. In short i am trying to learn, the consequence of each and every action. When i plug in a cable what...

    Schematic for a Networking Hub and Switch

    Hello, I am trying to find out the schematic for at Networking hub and switch, to better understand collision and broadcast and duplex logic. I was re-visiting the ethernet cabling ( straight through ,cross over etc etc) . I mentioned that (1,2) are used for Transmitting and (3,6) are used...

    Actual Packet : A PHY Layer question

    Coming to think about it, yes the original signal has no meaning!!!!! I think weather digital or analog, once the signal is processed the original signal is no more, it is reconstructed, i guess, i would have to read of Reciever and circuit to really understand it. The question to start with was...

    Actual Packet : A PHY Layer question

    Hello, a) My node generates a packet ( a PAM Signal in Ethernet , or 64-QAM in WiFi) b) When the packet reaches the switch/access point and let us presume that the packet has to go to the 4.2.2.2 (Public DNS)., what will happen to the original signal ( that is generated by my node (laptop) ) ...

    RF Propogation through solid objects

    Hello, Thank you for your responses. So what i understand is that RF Signals cannot pass through solid objects. Actually i understand the Nylon Clothes or Jeans we put are are not the same thickness as in metal. I was trying to imagine visually what path the RF Signal takes, in an office...

    RF Propogation through solid objects

    Good Morning, I have a quest about how an RF Wave behaves, when it encounter a solid objects. I was under the impression, when an RF wave encounter an obstacle (dry wall, metal, body) That the RF wave will pass through the molecules, in the sense because since the electron are randomly and...

    AC over DC

    I am sure, i know it is annoying for asking generic questions. Actually. I will be very careful in what i post, see that Siemens website what what i was talking about. Actually i am into WiMAX and Networking . But along the way i also want to understand nature. Because Electrical Engineering is...

    AC over DC

    Thank you for the good schooling you all. So i never understood electricity or the whole science. Now could you tell me how i can understand any books that will help me. Where do you people suggest i start. I am taking baby steps again.I want to learn. Thanks Bharat Chandra Penumutchu

    AC over DC

    Sorry for being vague. I was watching the "War of currents" yesterday, and they were talking about How D.C needed stations every 2 mile how AC could be transmitted over 100 or miles ( Step Up Step Down) etc etc. I wanted to know the science behind the AC signal. I was always fascinated but...

    AC over DC

    Could any one be kind enough to tell me why AC is more powerful than D.C. I did not find any convincing argument over Google.I wanted to hear from experts. I am taking baby steps.
