    Very grateful for this dissection of the process. This is a great example of good teaching where you've taken something really complex and broken it down into small chunks which are easy to take in. Bravo, dude.

    The IPv6 protocol does not use header checksums. Its designers considered that the whole-packet link layer checksumming provided in protocols, such as PPP and Ethernet, combined with the use of checksums in upper layer protocols such as TCP and UDP, are sufficient.

    I have been watching about since about years about fetch-decode-execute cycle,but I haven't catch a significant points comparing with the time I consume. What is the prior topic I should attend to understand well.

    in this case operand shows the content to be added on, but sometimes CIR holds opcode+ Address of the content that the instruction is to be executed on. how to identify that?

    awesome video but one question...! How did four get stored in the accumulator??

    • @franklinmirandadossantos8315
      @franklinmirandadossantos8315 8 лет назад +2

      I think it was alread there, it was loaded there in the previous instruction that obvious wasn't showed in the video, and when an instruction has ADD as an opcode, it means that it has to add whatever there is in the accumulator, with that operand of that ADD instruction.

    wheres memory data register? is it essentially the memory buffer? If someone could help it would be greatly appreciated i have exams soon.

    Does the CPU fetch the instructions from the Hard Drive or does it fetch it from the RAM?

    • @CompFranklin
      @CompFranklin  8 лет назад +1

      +john rear fetches from RAM - instructions are also loaded into RAM from any secondary storage device still via data bus

    • @memelord9965
      @memelord9965 8 лет назад

      +Comp Franklin So the CPU fetches the instructions from the RAM via the address bus and the instruction (after being fetched) is sent back to the CPU via the data bus?

    • @TonyTigerTonyTiger
      @TonyTigerTonyTiger 4 года назад +1

      @@memelord9965 The address bus is just for selecting which address in RAM to work with (read or write). The data that is read from or written to RAM travels across the data bus.
      Everything in the diagram - other than main memory and the buses connected to it - is the CPU. So when an instruction gets to the Memory Buffer Register, the instruction is in the CPU.
